Automatic EngineStart/Stop FeatureStart the engine as you would anyother engine. See “Starting theEngine” in the owner manual formore information on starting. Thehybrid system provides very quietengine starting. If pulling a trailerwith trailer brakes, see TrailerTowing on page 9‑9 for moreinformation.

Auto Stop

The vehicle has an Auto Stopfeature. After a successful enginestart, the engine may turn off andoperate in the Auto Stop mode.

Keep your foot firmly on the brakepedal until you are ready for thevehicle to move.

Engine OFF and AUTO STOPmodes are indicated on thetachometer display. When thetachometer needle indicates OFF,the engine is not running and willremain off until the ignition key isplaced in the START position or aremote vehicle start is performed.When the tachometer needleindicates AUTO STOP, the hybridsystem is on, the engine is notrunning, but may Auto Start at anytime without notice. See Tachometeron page 5‑3 for more information.

A chime will sound if the driver dooris opened while in Auto Stop as areminder that the ignition switch isnot in the LOCK/OFF position.Always turn the ignition switch toLOCK/OFF and remove the keyfrom the ignition switch when exitingthe vehicle.

Auto Start

The vehicle also has an Auto Startfeature. The engine will remain offwhile in Auto Stop mode untilvehicle conditions require theengine to run. The near-instantstarting of the engine from AutoStop mode is called Auto Start.

EV Mode

The vehicle also has an EV modewhich uses only the electric motorto move the vehicle. With lightacceleration, the vehicle will drive inEV mode. EV mode is unavailablewhen the vehicle is out of fuel.

For more information on Auto Stop,Auto Start, and EV Mode, seeStarting the Vehicle on page 9‑2.


1-4 In Brief

Regenerative BrakingRegenerative braking enables theelectric drive motor to operate as agenerator when coasting or braking.Energy from the moving vehiclerecharges the hybrid battery.

The hydraulic disc brakes work withthe regenerative braking to insureeffective braking.

The braking system iscomputer controlled and blendsthe regenerative braking with theconventional hydraulic disc brakesto meet any requirements fordeceleration. Because the controllerapplies the hydraulic brakes throughits high pressure accumulator, youmay occasionally hear the motordriven pump when it recharges thesystem. This is normal. In the eventof a controller problem, the brakepedal may be harder to push andthe stopping distance may belonger.

See Regenerative Braking onpage 9‑8.

BatteryThis vehicle has a standard 12-voltbattery and a high voltage hybridbattery. When a new standard12-volt battery is needed, seeyour dealer for one that has thereplacement number shown onthe original battery's label. Only atrained service technician with theproper knowledge and tools shouldinspect, test, or replace the hybridbattery. See your dealer if the hybridbattery needs service. See Batteryon page 10‑13.

ServiceNever try to do your own service onhybrid components. You can beinjured and the vehicle can bedamaged if you try to do your ownservice work. Service and repair ofthese hybrid components shouldonly be performed by a trainedservice technician with the properknowledge and tools. See DoingYour Own Service Work onpage 10‑2.

When the ignition is in ON/RUN, thetachometer indicates the vehiclestatus.

When pointing to AUTO STOP, thevehicle is on and can move. theengine could AUTO START at anytime. when the indicator is OFF,the vehicle is off. when the engineis on, the tachometer will indicatethe engine's revolutions perminute (rpm).

The tachometer may vary by severalhundred rpm's, during AUTO STOPmode, when the engine is shuttingoff and restarting. A slight bumpmay be felt when the transmission isdetermining the most fuel efficientoperating range.

Fuel Gauge

Metric

English

When the ignition is on, the fuelgauge shows approximately howmuch fuel is left in the fuel tank. Anarrow on the fuel gauge indicatesthe side of the vehicle the fuel dooris on. The gauge first indicatesE (empty) before the vehicle is outof fuel, but the vehicle should berefueled as soon as possible.



Listed are four situations that mayoccur with the fuel gauge, none ofthese indicate a problem:. At the gas station, the fuel pump

shuts off before the gauge readsF (full).

. It takes a little more or less fuelto fill up than the fuel gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.

. The gauge moves a little whileturning a corner or whileaccelerating.

. The gauge does not go backto E (empty) when the ignition isturned off.

The gauge moves to the leftwhen braking and to the right whenaccelerating. When either are doneaggressively, the efficiency isdecreased.



Engine Oil PressureGauge

Metric

English

The oil pressure gauge shows theengine oil pressure in psi (poundsper square inch) when the engine isrunning. Canadian vehicles indicatepressure in kPa (kilopascals). Theoil pressure gauge will read zerowhen operating in the AUTOSTOP mode.

Oil pressure should be 200 to550 kPa (29 to 80 psi). In certainsituations, such as long extendedidles on hot days, it could read aslow as 105 kPa (15 psi) and still beconsidered normal.

When the engine is runningreadings in the low pressure zonemay be caused by a dangerouslylow oil level or some other problemscausing low oil pressure. Check theoil as soon as possible.

{ WARNING

Do not keep driving if the oilpressure is low. The engine canbecome so hot that it catches fire.Someone could be burned. Checkthe oil as soon as possible andhave the vehicle serviced.

Notice: Lack of proper engine oilmaintenance can damage theengine. The repairs would not becovered by the vehicle warranty.Always follow the maintenanceschedule for changing engine oil.



AUTO STOP

When the engine is in AUTO STOPmode, the oil pressure gauge dropsto zero. Oil pressure returns to thenormal operating range after theengine starts.

Starting andOperating

Starting the Vehicle

{ WARNING

Exiting the vehicle, without firstshifting into P (Park), may causethe vehicle to move, and you orothers can be seriously injured.Because the vehicle has theAutomatic Engine Start/Stopfeature, the vehicle’s enginemight seem to be shut off whenyou come to a complete stop.However, once the brake pedal isreleased, the vehicle can move.The vehicle’s engine can alsorestart at any time.

Shift to P (Park) and turn theignition to LOCK/OFF, beforeexiting the vehicle.

Start the engine as you would anyother engine. See “Starting theEngine” in the owner manual formore information on starting.If pulling a trailer with trailer brakes,see Towing Equipment onpage 9‑10 for more information.

Auto Stop

The vehicle has an Auto Stopfeature. After a successful enginestart, the engine may turn off andoperate in the Auto Stop mode.Some of the vehicle conditions thatallow the engine to stop running andenter the Auto Stop mode are:. Ignition switch is in the ON/RUN

position.. The hood is closed.. The gear selector is in P (Park),

R (Reverse), N (Neutral) orD (Drive).

. The hybrid battery is at anacceptable state of charge.

. The hybrid battery voltage,temperature or power limits arenot exceeded. In very hotconditions, Auto Stop may beunavailable until the hybridbattery has cooled.

. The engine is at operatingtemperature.

. The vehicle may enter Auto Stopafter a remote vehicle start.

With your foot off the brake and thevehicle on level ground, the hybriddrive motor may cause the vehicleto roll slowly forward, even when theengine is in Auto Stop.

Keep your foot firmly on the brakepedal until you are ready for thevehicle to move.

Engine OFF and AUTO STOPmodes are indicated on thetachometer display. When thetachometer needle indicates OFF,the engine is not running and willremain off until the ignition key isplaced in the START position or aremote vehicle start is performed.



When the tachometer needleindicates AUTO STOP, the hybridsystem is on, the engine is notrunning, but may Auto Start at anytime without notice. See Tachometeron page 5‑3 for more information.

A chime will sound if the driver dooris opened while in Auto Stop as areminder that the ignition switch isnot in the LOCK/OFF position.Always turn the ignition switch toLOCK/OFF and remove the keyfrom the ignition switch when exitingthe vehicle.

Auto Start

The vehicle also has an Auto Startfeature. The engine will remain offwhile in Auto Stop mode untilvehicle conditions require theengine to run. The near-instantstarting of the engine from AutoStop mode is called Auto Start.

Some of the vehicle conditions thatmay cause the engine to AutoStart are:. The hood is opened.. The gear selector is in

M (Manual Mode).. The hybrid battery state of

charge is too low.. The hybrid battery voltage,

temperature or power limits areexceeded.

. A remote vehicle start has beenrequested.

. The engine is not at operatingtemperature.

. Acceleration demands requirethe use of the engine.

EV Mode

The vehicle also has an ElectricVehicle (EV) mode which uses onlythe electric motor to move thevehicle. With light acceleration, thevehicle will drive in EV mode. EVmode is unavailable when thevehicle is out of fuel.

If increased acceleration isrequired, or the vehicle reachesapproximately 40 km/h (30 mph), theengine will start automatically. Theengine shuts off at speeds below40 km/h (25 mph) unless thetransmission is in M (Manual Mode)or Auto Stop is disabled.

During heavy acceleration, both theengine and hybrid electric motorssupply power. A sensation similar toa transmission gear change can befelt as the transmission changesmodes. Engine RPM may remainabove 4,000 RPM for a longerperiod during hard acceleration.



Engine Coolant HeaterThe engine coolant heater canprovide easier starting and betterfuel economy during enginewarm-up in cold weather conditionsat or below −18°C (0°F). Vehicleswith an engine heater should beplugged in at least four hours beforestarting. An internal thermostat inthe plug-end of the cord may existwhich will prevent engine coolantheater operation at temperaturesabove −18°C (0°F).

Using the Engine CoolantHeater

1. Turn off the engine.

2. Open the hood and unwrap theelectrical cord. The cord issecured to a wiring harnessbetween the engine and theHybrid Auxiliary UnderhoodFuse Block with a clip.

Carefully remove the wire tiewhich secures the electricalcord. Do not cut theelectrical cord.

3. Plug the cord into a normal,grounded 110-volt AC outlet.

{ WARNING

Plugging the cord into anungrounded outlet could causean electrical shock. Also, thewrong kind of extension cordcould overheat and cause a fire.You could be seriously injured.Plug the cord into a properlygrounded three-prong 110-volt ACoutlet. If the cord will not reach,use a heavy-duty three-prongextension cord rated for at least15 amps.

4. Before starting the engine, besure to unplug and store thecord as it was before to keep itaway from moving engine parts.If you do not, it could bedamaged.

The length of time the heater shouldremain plugged in depends onseveral factors. Ask a dealer in thearea where you will be parking thevehicle for the best advice on this.



Engine Exhaust

Running the VehicleWhile ParkedIt is better not to park with theengine running. But if you ever haveto, here are some things to know.

{ WARNING

Exiting the vehicle, without firstshifting into P (Park), may causethe vehicle to move, and you orothers can be seriously injured.Because the vehicle has theAutomatic Engine Start/Stopfeature, the vehicle’s enginemight seem to be shut off whenyou come to a complete stop.

(Continued)

WARNING (Continued)

However, once the brake pedal isreleased, the vehicle can move.The vehicle’s engine can alsorestart at any time.

Shift to P (Park) and turn theignition to LOCK/OFF, beforeexiting the vehicle.

Follow the proper steps to be surethe vehicle will not move. See“Shifting Into Park” in the ownermanual for more information.

If pulling a trailer, see “DrivingCharacteristics and Towing Tips” inthe owner manual.

AutomaticTransmissionThe vehicle has an electronic shiftposition indicator within theinstrument panel cluster.

There are several different positionsfor the shift lever.

See “Range Selection Mode” in thissection.

P (Park): This position locks therear wheels. It is the best position touse when you start the enginebecause the vehicle cannot moveeasily.

When parked on a hill, especiallywhen the vehicle has a heavy load,you may notice an increase in theeffort to shift out of P (Park).



See “Shifting Into Park” in the Indexof vehicle's owner manual for moreinformation.

{ WARNING

It is dangerous to get out of thevehicle if the shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.

Do not leave the vehicle when theengine is running unless youhave to. If you have left theengine running, the vehicle canmove suddenly. You or otherscould be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brake andmove the shift lever to P (Park).See “Shifting Into Park” in theowner manual. If you arepulling a trailer, see “DrivingCharacteristics and Towing Tips”in the owner manual.

{ WARNING

If you have Four-Wheel Drive, thevehicle will be free to roll— evenif the shift lever is in P (Park)— ifthe transfer case is in Neutral. So,be sure the transfer case is in adrive gear, Two-Wheel Drive Highor Four-Wheel Drive High orFour-Wheel Drive Low— not inNeutral. See “Shifting Into Park”in the owner manual.

R (Reverse): Use this gear toback up.

Notice: Shifting to R (Reverse)while the vehicle is movingforward could damage thetransmission. The repairs wouldnot be covered by the vehiclewarranty. Shift to R (Reverse) onlyafter the vehicle is stopped.

To rock the vehicle back and forth toget out of snow, ice, or sand withoutdamaging the transmission, see “Ifthe Vehicle is Stuck” in the Index ofthe vehicle's owner manual.

N (Neutral): In this position, theengine and transmission are notconnected with the wheels. Torestart the engine when the vehicleis already moving, useN (Neutral) only.

{ WARNING

Shifting into a drive gear while theengine is running at high speed isdangerous. Unless your foot isfirmly on the brake pedal, thevehicle could move very rapidly.You could lose control and hitpeople or objects. Do not shiftinto a drive gear while the engineis running at high speed.



Notice: Shifting out of P (Park) orN (Neutral) with the enginerunning at high speed maydamage the transmission. Therepairs would not be covered bythe vehicle warranty. Be sure theengine is not running at highspeed when shifting the vehicle.

D (Drive): This position is fornormal driving. It provides the bestfuel economy. If you need morepower for passing, and you are:. Going less than about 55 km/h

(35 mph), push the acceleratorpedal about halfway down.

. Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.

D (Drive) or M (Manual Mode) canbe used when towing a trailer,carrying a heavy load, driving onsteep hills, or for off-road driving.You may want to shift thetransmission to a lower gearselection if the transmission shiftstoo often.

Downshifting the transmission inslippery road conditions could resultin skidding. See “Skidding” under“Loss of Control” in the ownermanual for more information.

When temperatures are very cold,the transmission's gear shifting maybe delayed, providing more stableshifts until the engine warms up.Shifts may be more noticeable witha cold transmission. This differencein shifting is normal.

M (Manual Mode): This positionlets drivers select the range of gearsappropriate for current drivingconditions. If the vehicle has thisfeature, see Manual Mode onpage 9‑7.

Notice: Spinning the tires orholding the vehicle in one placeon a hill using only theaccelerator pedal may damagethe transmission. The repair willnot be covered by the vehiclewarranty. If you are stuck, do not

spin the tires. When stopping ona hill, use the brakes to hold thevehicle in place.

The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions to reduce rapid upshiftsand downshifts. If the shiftstabilization feature determines thata current vehicle speed cannot bemaintained, the transmission doesnot upshift. In some cases, this mayappear to be a delayed shift,however the transmission isoperating normally.

Manual Mode

Range Selection Mode

The Range Selection Mode controlsthe vehicle's transmission.



To use this feature:

1. Move the shift lever to theM (Manual Mode).

2. Press the plus/minus button toupshift or downshift selecting thedesired range of gears.

A number displays next to the M,indicating the current gear thathas been selected. The numberdisplayed in the gear indicator is thehighest gear that can be used. Thevehicle can automatically shift tolower gears as it adjusts to drivingconditions. When 3 (Third) isselected, 1 (First) through 3 (Third)gears are automatically shifted bythe vehicle, but 4 (Fourth) cannot beused until it is selected.

The Range Selection Mode controlsthe vehicle and engine speed whiledriving down a hill or towing a trailer,by allowing you to select a desiredrange of gears.

When you move the shift lever intoM, the transmission will default toM4. In this gear range, effectiveengine braking occurs at speedsabove 72 km/h (45 mph).

Pushing the minus (−) button on theshift lever reduces the gear range.

In the M3 gear range, effectiveengine braking occurs at speedsabove 56 km/h (35 mph).



When operating in M (ManualMode), Auto Stop is disabled.For better vehicle efficiency, operatethe vehicle in D (Drive) notM (Manual Mode).

Cruise control can be used whileusing the Range Selection Mode.

Brakes

Regenerative BrakingRegenerative braking is a hybridtechnology that enables theelectric drive motor to operate as agenerator when coasting or braking.Energy from the moving vehiclerecharges the hybrid battery.

The hydraulic disc brakes work withthe regenerative braking to insureeffective braking, such as when ahigh braking demand is requested.

The braking system is computercontrolled and blends theregenerative braking with theconventional hydraulic disc brakesto meet any requirements fordeceleration. The controllerinterprets the braking requestand uses regenerative braking,conventional hydraulic braking or acombination of both as necessary.



Because the controller applies thehydraulic brakes through its highpressure accumulator, you mayoccasionally hear the motor drivenpump when it recharges the system.This is normal.

In the event of a controller problem,the brake pedal may be harder topush and the stopping distance maybe longer.

Towing

General TowingInformationConsult your dealer or aprofessional towing service if thedisabled vehicle needs to be towed.

Trailer TowingFor more information, see “TrailerTowing” in the owner manual.

Weight of the Trailer

How heavy can a trailer safely be?

It depends on how the rig is used.For example, speed, altitude, roadgrades, outside temperature andhow much the vehicle is used to pulla trailer are all important. It candepend on any special equipmenton the vehicle, and the amount oftongue weight the vehicle can carry.

Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment. Theweight of additional optionalequipment, passengers and cargo inthe tow vehicle must be subtractedfrom the maximum trailer weight.



Use the following charts to determine how much the vehicle can weigh, based upon the vehicle model and options.

Vehicle Axle Ratio Maximum Trailer Weight GCWR*

2WD 6.0 L V8 3.08 2 767 kg (6,100 lbs) 5 443 kg (12,000 lbs)

4WD 6.0 L V8 3.08 2 676 kg (5,900 lbs) 5 443 kg (12,000 lbs)

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle andtrailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not beexceeded.

Towing Equipment

Trailer Brakes

If a trailer is being towed that hastrailer brakes and the trailer brakesare manually applied while drivingslower than 40 km/h (25 mph), thevehicle may go into Auto Stop modeeven if the brakes are not beingpressed. Using the trailer brake

system manually can make thehybrid vehicle perform as if thebrake pedal in the vehicle is beingpressed. The trailer brake operationcheck will still work. If the trailerbrakes are manually applied for anextended period of time, theSERVICE BRAKE SYSTEM

message comes on in the DriverInformation Center. The messagegoes off after the trailer brakes havebeen released. No other action isnecessary. For more information,see “Towing Equipment” in theowner manual.

Automatic TransmissionFluid

When to Check and ChangeAutomatic Transmission Fluid

It is usually not necessary tocheck the transmission fluid level.The only reason for fluid loss is atransmission leak or overheating thetransmission. If a small leak issuspected, then use the followingchecking procedures to check thefluid level. However, if there is alarge leak, then it may be necessaryto have the vehicle towed to adealer and have it repaired beforedriving the vehicle further.

Notice: Use of the incorrectautomatic transmission fluidmay damage the vehicle, and thedamages may not be covered bythe vehicle warranty. Always usethe automatic transmission fluidlisted in Recommended Fluidsand Lubricants on page 11‑2.

Change the fluid and filter at thescheduled maintenance intervals.See “Scheduled Maintenance” inthe owner manual. Be sure to usethe transmission fluid listed inRecommended Fluids andLubricants on page 11‑2.

How to Check AutomaticTransmission Fluid

Notice: Too much or toolittle fluid can damage thetransmission. Too much canmean that some of the fluid couldcome out and fall on hot engineparts or exhaust system parts,starting a fire. Too little fluidcould cause the transmission tooverheat. Be sure to get anaccurate reading if checking thetransmission fluid.

Before checking the fluid level,prepare the vehicle as follows:

1. Start the engine and park thevehicle on a level surface. Keepthe engine running.

2. Apply the parking brake andplace the shift lever in P (Park).

3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about three secondsin each range. Then, move theshift lever back to P (Park).

4. Allow the engine to idle(500–800 RPM) for at leastone minute. Slowly release thebrake pedal.

5. Keep the engine running andpress the Trip/Fuel button or tripodometer reset stem untilTRANS TEMP (TransmissionTemperature) displays on theDriver Information Center (DIC).


Vehicle Care 10-7

6. Using the TRANS TEMPreading, determine andperform the appropriate checkprocedure. If the TRANS TEMPreading is not within the requiredtemperature ranges, allow thevehicle to cool, or operate thevehicle until the appropriatetransmission fluid temperature isreached.

Cold Check Procedure

Use this procedure only as areference to determine if thetransmission has enough fluid to beoperated safely until a hot checkprocedure can be made. The hotcheck procedure is the mostaccurate method to check the fluidlevel. Perform the hot checkprocedure at the first opportunity.Use this cold check procedure tocheck fluid level when thetransmission temperature isbetween 24°C and 34°C(75°F and 93°F).

1. Locate the transmissiondipstick at the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑4 for moreinformation.

2. Pull out the dipstick and wipe itwith a clean rag or paper towel.

3. Install the dipstick by pushingit back in all the way, waitthree seconds, and then pull itback out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.

5. If the fluid level is below theCOLD check band, add onlyenough fluid as necessary tobring the level into the COLDband. It does not take muchfluid, generally less than 0.5 Liter(1 Pint). Do not overfill.

6. Perform a hot check at thefirst opportunity after thetransmission reaches anormal operating temperaturebetween 60°C and 75°C(140°F and 167°F).

7. If the fluid level is in theacceptable range, push thedipstick back in all the way.


10-8 Vehicle Care

Hot Check Procedure

Use this procedure to check thetransmission fluid level when thetransmission fluid temperatureis between 60°C and 75°C(140°F and 167°F).

The hot check is the most accuratemethod to check the fluid level. Thehot check should be performed atthe first opportunity in order to verifythe cold check. The fluid level risesas fluid temperature increases,so it is important to ensure thetransmission temperature is withinrange.

1. Locate the transmission dipstickat the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑4 for moreinformation.

2. Pull out the dipstick and wipe itwith a clean rag or paper towel.

3. Install the dipstick by pushingit back in all the way, waitthree seconds, and then pull itback out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.

5. Safe operating level is within theHOT cross hatch band on thedipstick. If the fluid level is notwithin the HOT band, and thetransmission temperature isbetween 60°C and 75°C(140°F and 167°F), add ordrain fluid as necessary to bringthe level into the HOT band.If the fluid level is low, add onlyenough fluid to bring the levelinto the HOT band. It does nottake much fluid, generally lessthan 0.5 Liter (1 Pint). Do notoverfill.

6. If the fluid level is in theacceptable range, push thedipstick back in all the way.


Vehicle Care 10-9

Consistency of Readings

Always check the fluid level at leasttwice using the procedure describedpreviously. Consistency (repeatablereadings) is important to maintainingproper fluid level. If readings are stillinconsistent, contact your dealer.

Drive Motor/GeneratorControl Module (DMCM)Coolant Surge TankPressure Cap

See Engine Compartment Overviewon page 10‑4 for more informationon location.

The Drive Motor/Generator ControlModule (DMCM) coolant surge tankpressure cap must be fully installedon the hybrid coolant surge tank.

Notice: If the pressure cap isnot tightly installed, coolant lossand possible damage to theDrive Motor/Generator ControlModule (DMCM) may occur. Besure the cap is properly andtightly secured.

Drive Motor/GeneratorControl Module (DMCM)Cooling SystemIn addition to the regular coolingsystem, the vehicle also has acooling system for the DMCMsystem. This system is serviceddifferently than the vehicle's maincooling system. The DMCM coolingsystem includes the DMCM coolantsurge tank, DMCM surge tankpressure cap, DMCM coolingpumps, hybrid cooling radiatorand the Drive Motor/GeneratorControl Module (DMCM). TheDMCM cooling system uses a 50/50pre-mixed DEX-COOL® coolant anddeionized water available at yourdealer. See “Engine Coolant” and“Cooling System” in the ownermanual for more information.

E. DMCM Coolant Surge TankPressure Cap

If the coolant inside the DMCMcoolant surge tank is boiling, do notdo anything else until it cools down.

The coolant level should be at orabove the FULL COLD mark withthe vehicle parked on a levelsurface. If it is not, there might be aleak at the DMCM cooler core,DMCM pressure cap, DMCM coolerhoses, DMCM cooling pump orsomewhere else in the DMCMcooling system.

Notice: Running the engine whenthere is a leak in the hybridcooling system can cause thehybrid cooling system to lose allcoolant and can damage thesystem. Get any leak fixed beforeyou drive the vehicle or run theengine.

How to Add Coolant to theDMCM Coolant Surge Tank

If no problem has been found yet,check to see if coolant is visible inthe DMCM coolant surge tank.If coolant is visible, add pre‐mixedDEX-COOL coolant, available atyour dealer, at the DMCM coolantsurge tank, but be sure the DMCMcooling system, including the DMCMcoolant surge tank pressure cap, iscool before you do it. Use theprocedure following.


Vehicle Care 10-11

{ WARNING

Steam and scalding liquids from ahot cooling system can blow outand burn you badly. They areunder pressure, and if you turnthe coolant surge tank pressurecap— even a little— they cancome out at high speed. Neverturn the cap when the coolingsystem, including the coolantsurge tank pressure cap, is hot.Wait for the cooling system andcoolant surge tank pressure capto cool if you ever have to turnthe pressure cap.

Electrical System

High Voltage Devices andWiring

{ WARNING

Exposure to high voltagecan cause shock, burns, andeven death. The high voltagecomponents in the vehicle canonly be serviced by technicianswith special training.

High voltage components areidentified by labels. Do notremove, open, take apart,or modify these components.High voltage cable or wiring hasorange covering. Do not probe,tamper with, cut, or modify highvoltage cable or wiring.

Fuses and CircuitBreakersThe wiring circuits in the vehicleare protected from short circuits bya combination of fuses, circuitbreakers and fusible thermal links.This greatly reduces the chance offires caused by electrical problems.

Be sure you replace a bad fuse witha new one of the identical size andrating.

If you ever have a problem on theroad and do not have a spare fuse,you can borrow one that has thesame amperage. Just pick somefeature of the vehicle that you canget along without, like the radio orcigarette lighter, and use its fuse,if it is the correct amperage.Replace it as soon as you can.

The vehicle also has a special fusein the battery box for the 300-voltbatteries. If this fuse has failed andneeds to be replaced, the vehiclewill be disabled and you will need tohave the vehicle repaired by yourdealer. Do not attempt toself-service this fuse.

{ WARNING

Personal injury, death, or damageto the vehicle can result if you tryjump starting or using a batterycharger on the high voltagehybrid battery. Use only the12-volt battery for jump startingand charging.

For more information about thevehicle's batteries, see Battery onpage 10‑13.

If the vehicle's 12‐volt battery hasrun down, you may want to useanother vehicle and some jumpercables to start your vehicle. Use thefollowing steps to do it safely.

{ WARNING

Batteries can hurt you. They canbe dangerous because:

. They contain acid that canburn you.

. They contain gas that canexplode or ignite.

. They contain enoughelectricity to burn you.

If you do not follow these stepsexactly, some or all of thesethings can hurt you.

Notice: Ignoring these stepscould result in costly damage tothe vehicle that would not becovered by the warranty.


Vehicle Care 10-17

Trying to start the vehicle bypushing or pulling it will notwork, and it could damage thevehicle.

1. Check the other vehicle. It musthave a 12‐volt battery with anegative ground system.

Notice: Only use a vehicle thathas a 12-volt system with anegative ground for jumpstarting. If the other vehicle doesnot have a 12-volt system with anegative ground, both vehiclescan be damaged.

2. Get the vehicles close enoughso the jumper cables can reach,but be sure the vehicles are nottouching each other. It couldcause a ground connection youdo not want. You would not beable to start your vehicle, andthe bad grounding could damagethe electrical systems.

To avoid the possibility of thevehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put the automatictransmission in P (Park) or amanual transmission inN (Neutral) before setting theparking brake. If you have afour-wheel-drive vehicle, be surethe transfer case is in a drivegear, not in N (Neutral).

Notice: If any accessories are lefton or plugged in during the jumpstarting procedure, they couldbe damaged. The repairs wouldnot be covered by the vehiclewarranty. Whenever possible,turn off or unplug all accessorieson either vehicle when jumpstarting the vehicle.

3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into thecigarette lighter or the accessorypower outlets. Turn off the radioand all the lamps that are notneeded.

This avoids sparks and helpssave both batteries. It couldsave the radio!

4. Open the hood on the othervehicle and locate thepositive (+) and negative (−)terminal locations on thatvehicle.


10-18 Vehicle Care

The positive (+) connection islocated under a red plastic coverat the positive battery post. Touncover the remote positive (+)terminal, open the red plasticcover.

5. The remote negative (−) is asolid engine ground.

{ WARNING

An electric fan can start up evenwhen the engine is not runningand can injure you. Keep hands,clothing and tools away from anyunderhood electric fan.

{ WARNING

Using an open flame near abattery can cause battery gas toexplode. People have been hurtdoing this, and some have beenblinded. Use a flashlight if youneed more light.

Be sure the battery has enoughwater. You do not need to addwater to the battery installed inyour new vehicle. But if a batteryhas filler caps, be sure the rightamount of fluid is there. If it is low,

(Continued)

WARNING (Continued)

add water to take care of thatfirst. If you do not, explosive gascould be present.

Battery fluid contains acid thatcan burn you. Do not get it onyou. If you accidentally get it inyour eyes or on your skin, flushthe place with water and getmedical help immediately.

{ WARNING

Fans or other moving engineparts can injure you badly. Keepyour hands away from movingparts once the engine is running.

6. Check that the jumper cablesdo not have loose or missinginsulation. If they do, you couldget a shock. The vehicles couldbe damaged too.


Vehicle Care 10-19

Before you connect the cables,here are some basic things youshould know. Positive (+) goesto positive (+) or to a remotepositive (+) terminal if the vehiclehas one. Negative (−) will go to aheavy, unpainted metal enginepart or a solid engine ground.

Do not connect positive (+) tonegative (−) or you will get ashort that would damagethe battery and maybe otherparts too. Do not connect thenegative (−) cable to thenegative (−) terminal on the deadbattery because this can causesparks.

7. Connect the red positive (+)cable to the positive (+) terminalof the vehicle with the deadbattery. Use a remotepositive (+) if the vehiclehas one.

8. Do not let the other end touchmetal. Connect it to thepositive (+) terminal of thegood battery. Use a remotepositive (+) if the vehiclehas one.

9. Now connect the blacknegative (−) cable to thenegative (−) terminal of thegood battery. Use a remotenegative (−) if the vehiclehas one.

Do not let the other end touchanything until the next step. Theother end of the negative (−)cable does not go to the deadbattery. It goes to a heavy,unpainted metal engine part orto the remote negative (−)terminal on the vehicle with thedead battery.

10. Connect the other end of thenegative (−) cable to theremote negative (−) terminal,on the vehicle with the deadbattery.

11. Now start the vehicle with thegood battery and run theengine for a while.

12. Try to start the vehicle that hadthe dead battery. If it will notstart after a few tries, itprobably needs service.

Notice: If the jumper cables areconnected or removed in thewrong order, electrical shortingmay occur and damage thevehicle. The repairs would not becovered by the vehicle warranty.Always connect and remove thejumper cables in the correctorder, making sure that thecables do not touch each other orother metal.
