    Environmental Concerns andRecommendationsWhenever you see instructions in this manual to dis-card materials, you should first attempt to reclaimand recycle them. To preserve our environment, fol-low appropriate environmental rules and regulationswhen disposing of materials.

    Event Data RecorderThis vehicle is equipped with one or more devicesthat record specific vehicle data. The type andamount of data recorded varies depending on howthe vehicle is equipped (such as the brand of engine,if an air bag is installed, or if the vehicle features acollision avoidance system, etc.).This vehicle is equipped with an event data recorder(EDR). The main purpose of an EDR is to recorddata in certain crash or near-crash situations, suchas air bag deployment or hitting a road obstacle, thatwill assist in understanding how a vehicles systemsperformed. The EDR is designed to record data re-

    lated to vehicle dynamics and safety systems for ap-proximately 60 seconds. This data can help providea better understanding of the circumstances in whichcrashes and injuries occur. Data recorded includesthe following items:

    how various systems in the vehicle were oper-ating

    engine system information how far (if at all) the driver was depressing the

    accelerator if the driver was depressing the brake pedal how fast the vehicle was traveling

    NOTE: Data is not recorded by the EDR undernormal driving conditions. Personal data suchas name, gender, age, and crash location arenot recorded. However, other parties such aslaw enforcement could combine the EDR datawith the type of personally identifying data rou-tinely acquired during a crash investigation.To read data recorded by an EDR, special equipmentis required, and access to the vehicle or the EDR isneeded. In addition to the vehicle manufacturer, otherparties that have the special equipment, such as lawenforcement, can read the information if they haveaccess to the vehicle or the EDR.

It also recaps the major assemblies and in-stallations shown on the chassis specification sheet.One copy of the specification decal is attached to thedrivers side sunvisor; another copy is inside the rearcover of the Owners Warranty Information for NorthAmerica booklet. An illustration of the decal is shownin Fig. 1.1.

    NOTE: Labels shown in this chapter are ex-amples only. Actual specifications may vary fromvehicle to vehicle.

    Federal Motor Vehicle SafetyStandard (FMVSS) LabelsNOTE: Due to the variety of FMVSS certificationrequirements, not all of the labels shown willapply to your vehicle.Tractors with or without fifth wheels purchased in theU.S. are certified by means of a certification label(Fig. 1.2) and the tire and rim labels (Fig. 1.3).These labels are attached to the left rear door post,as shown in Fig. 1.4.If purchased for service in the U.S., trucks built with-out a cargo body have a certification label (Fig. 1.5)attached to the left rear door post. See Fig. 1.4. Inaddition, after completion of the vehicle, a certifica-tion label similar to that shown in Fig. 1.2 must beattached by the final-stage manufacturer. This labelwill be located on the left rear door post and certifies

    that the vehicle conforms to all applicable FMVSSregulations in effect on the date of completion.

    Canadian Motor Vehicle SafetyStandard (CMVSS) LabelsIn Canada, tractors with fifth wheels are certified bymeans of a "Statement of Compliance" label and theCanadian National Safety Mark (Fig. 1.6), which areattached to the left rear door post. In addition, tireand rim labels (Fig. 1.3) are also attached to the leftrear door post.If purchased for service in Canada, trucks built with-out a cargo body and tractors built without a fifthwheel are certified by a "Statement of Compliance"label, similar to Fig. 1.2. This label must be attachedby the final-stage manufacturer after completion ofthe vehicle. The label is located on the left rear door

  • post, and certifies that the vehicle conforms to allapplicable CMVSS regulations in effect on the dateof completion.

    Tire and Rim LabelsTire and rim labels certify suitable tire and rim combi-nations that can be installed on the vehicle, for thegiven gross axle weight rating. Tires and rims in-stalled on the vehicle at the time of manufacture mayhave a higher load capacity than that certified by thetire and rim label. If the tires and rims currently onthe vehicle have a lower load capacity than thatshown on the tire and rim label, then the tires andrims determine the load limitations on each of theaxles. See Fig. 1.3.

    EPA Emission ControlVehicle Noise Emission Control LabelA vehicle noise emission control label (Fig. 1.7) isattached either to the left side of the dashboard or tothe top-right surface of the frontwall between thedash and the windshield.

    IMPORTANT: Certain Freightliner incompletevehicles may be produced with incomplete noisecontrol hardware. Such vehicles will not have avehicle noise emission control information label.For such vehicles, it is the final-stage manufac-turers responsibility to complete the vehicle inconformity to U.S. EPA regulations (40 CFR Part205) and label it for compliance.EPA07 Exhaust EmissionsRegulationsTo meet January 2007 emissions regulations, en-gines manufactured after January 1, 2007, areequipped with an emission aftertreatment device.There is a warning label on the drivers sunvisor, ex-plaining important new warning indicators in thedrivers message display, that pertain to the after-treatment system. See Fig. 1.8.

  • Instrumentation Control UnitsThe instrumentation control unit (ICU) provides thedriver with engine and vehicle information. It is com-prised of standard and optional gauges, an audiblewarning, a driver message center, and a lightbar con-taining warning and indicator lamps (also known astelltales). Warning and indicator lamps illuminate inred (danger), amber (caution), green (status advi-sory), or blue (high-beam headlights activated).Century Class vehicles are equipped with either anICU4M (Fig. 2.1) or ICU2M (Fig. 2.2).The following headings in this chapter provide addi-tional information and operating instructions for ICUcomponents:

    "Warning and Indicator Lights" "Driver Message Center" "Instruments"

    Ignition SequenceWhen the ignition is turned on, the ICU runs a self-check. Observing the ignition sequence is a goodway to ensure the ICU is functioning properly.IMPORTANT: Do not crank the engine until theICU gauge sweep is complete.NOTE: Air gauges do not complete a sweep oftheir dials during the ignition sequence.When the ignition is turned on, the following actionsshould occur:

    electronic gauges complete a full sweep oftheir dials

    some warning and indicator lamps illuminate,then are extinguished

    IMPORTANT: If any red or amber warning orindicator lamps do not illuminate during the ICUself-check or do not extinguish after the self-check completes, take the action outlined inTable 2.1, or take the vehicle to an authorizedDaimler Trucks service facility as soon as pos-sible.NOTE: If active faults are present, take the ve-hicle to an authorized Daimler Trucks servicefacility as soon as possible.If the ICU receives active fault codes, it displaysthem one after the other until the parking brake isreleased or the ignition is turned off. Once the park-ing brake is completely released, the ICU displaysthe odometer. If there are no active faults, the ICUdisplays the odometer after the self-check completes.When the self-check is complete on an ICU4M, thefasten seat belt screen displays if the engine is off. Ifthe engine is running, the idle hours screen displays.

    Audible AlertsAn audible alert sounds during the ignition sequenceand whenever one of the following conditions exists:

    Engine oil pressure falls below the minimumpreset value.

    Coolant temperature rises above the maximumpreset value.

    Air pressure falls below approximately 70 psi(483 kPa).

    Parking brake is set with the vehicle movingfaster than two miles per hour.

    System voltage falls below 12 volts. Door is open or the headlights are on, with the

    parking brake off.

    Warning and Indicator LightsThe ICU lightbar has three or four rows of warningand indicator lights with icon symbols, depending onthe ICU. The positions of the lights may vary for thedifferent ICUs, but the telltales are standard for allapplications. See Table 2.1 for a listing of standardand commonly used warning and indicator lamps.Warning and indicator lamps illuminate in red (dan-ger), amber (caution), green (status advisory), orblue (high-beam headlights active).IMPORTANT: Depending upon local jurisdic-tional emissions guidelines, vehicles may not beequipped with all of the lamps shown inTable 2.1.

    Engine Protection System

    WARNINGWhen the red STOP engine lamp illuminates,most engines are programmed to shut down au-tomatically within 30 seconds. The driver mustimmediately move the vehicle to a safe locationat the side of the road to prevent causing a haz-ardous situation that could cause bodily injury,property damage, or severe damage to the en-gine.See Fig. 2.3 for an explanation of the aftertreatmentsystem (ATS) warning indicators, and actions re-quired to avoid further engine protection steps.

  • Common Warning and Indicator LampsLamp Description Color

    STOP STOP Engine *

    Indicates a serious fault that requires engine shutdownimmediately. The engine protection system reduces themaximum engine torque and speed, and, if the conditiondoes not improve, shuts down the engine within 30 to 60seconds.

    Safely bring the vehicle to a stop on the side of the roadand shut down the engine as soon as the red light is seen.IMPORTANT: If the engine shuts down while the vehicleis in a hazardous location, turn the key to the OFFposition for a few seconds, then restart the engine andmove the vehicle to a safer location.

    RedLow Air Pressure Indicates air pressure in the primary or secondary reservoiris below 70 psi (483 kPa).

    BRAKEParking Brake

    Indicates the parking brake is engaged. An audible alertactivates when the vehicle is moving over 2 mph (3 km/h)with the parking brake set.

    Low Battery Voltage Indicates that battery voltage is 11.9 volts or less.

    Unfastened Seat Belt

    Activates with an audible alert when the system detects thatthe parking brake is off and the driver seat belt is notfastened on some vehicles. On other vehicles, this lampilluminates for 15 seconds when the ignition is first turnedon.

    CHECK CHECK Engine *

    Indicates an engine condition (low oil pressure, low coolantlevel, high coolant temperature, high DPF soot level, oruncontrolled DPF regeneration) that requires correction.Correct the condition as soon as possible. If the conditionworsens, the STOP engine lamp illuminates.

    Amber

    High Exhaust SystemTemperature (HEST) *

    Slow (10-second) flashing indicates a regeneration (regen)is in progress.IMPORTANT: When the HEST lamp is illuminated, donot park the vehicle near flammable material.

    Solid illumination indicates high exhaust temperatures at theoutlet of the tail pipe when speed is below 5 mph (8 km/h).

  • The STOP engine lamp illuminates when the engineprotection system is activated in one of two ways. Onsome engines, the engine protection system deratesthe engine, allowing it to run at lower rpm and slowervehicle speed. Drive the vehicle to a safe location orto a service facility.IMPORTANT: Safely bring the vehicle to a stopon the side of the road and shut down the en-gine as soon as the red light is seen. If the en-gine shuts down while the vehicle is in a haz-ardous location, turn the key to the OFF positionfor a few seconds, then restart the engine andmove the vehicle to a safer location.On other engines, the engine protection systemshuts down the engine. It first derates the engine,then shuts it down completely 30 to 60 seconds afterthe indicator illuminates (depending on the criticalfault type) if the condition does not improve. Bringthe vehicle to a stop on the side of the road beforethe engine shuts down.Some vehicles may have a shutdown-overrideswitch, which may be used to momentarily overridethe shutdown sequence. See Chapter 7 for detailedinformation regarding the shutdown process.

    IMPORTANT: Do not attempt to restart the en-gine while the vehicle is moving. Bring the ve-hicle to a safe stop, then restart the engine.To restart the engine, turn the ignition switch to OFFfor a few seconds, then turn the ignition switch to ONand let the gauge sweep complete before starting theengine. The engine will run for a short period andshut down again if the condition does not improve.

  • Service intervals that are programmable via thekeypad.

    An audible warning and alert message to warnthe driver if the door is opened without first set-ting the parking brake.

    A flashing alert message that appears on thedriver message center in low engine oil pres-sure or high coolant temperature conditions.

    With the parking brake off, only the odometer andalert screens will display. Park the vehicle and setthe parking brake to access additional screens.The dash message center displays alert screenswhen certain conditions occur. They are warnings,cautions, or other messages that require the driversattention, but not all of them are critical to the opera-tion of the vehicle. Warning messages always displayat full brightness.More important messages take priority over less im-portant messages. The order of priority is:1. parking brake set (with the vehicle moving)2. parking brake off (with the door open)3. low oil pressure or high coolant temperature4. hard brake warnings (if equipped with roll stabil-

    ity advisor)5. low battery voltage6. turn signal on7. service warnings8. no datalink activity

    Alert ScreensNOTE: If there is more than one alert messageto display, tap any key to access the next mes-sage, and so on, until all the messages havebeen viewed.

    Parking Brake OnThis warning message and an audible warning comeon whenever the parking brake is applied and thevehicle is moving faster than 2 mph (3 km/h). Thescreen and audible warning go away only when theparking brake is released, or speed is reduced below2 mph.

    Low Oil PressureThis warning message and an audible warning comeon whenever the oil pressure falls below the mini-mum oil pressure, whether the vehicle is idling or inmotion. Tap any key to dismiss the message.If the fault is still active 30 seconds after the mes-sage is dismissed, the warning message will comeon again.

    High Coolant TempThis message and an audible warning come onwhenever the engine coolant temperature exceedsthe maximum allowable temperature.If the fault is still active 30 seconds after the mes-sage is dismissed, the warning message will comeon again.

    Low VoltageOn some vehicles, this optional message and an au-dible warning come on whenever the ICU detects alow voltage condition.

    Turn Signal OnThis warning message and audible warning come onwhenever the turn signal remains on for four minutesor five miles of travel.To dismiss this message, either turn off the turn sig-nal or tap any key.

    Service WarningsService warning screens display during the ignitionsequence and indicate that a service interval hasbeen reached or exceeded and maintenance is re-quired. The messages may indicate the number ofmiles (KM) or hours until the next required service or,once passed, the number of miles (KM) or hours agothat maintenance should have been performed.

It displaysone time only for seven seconds. It notifies the driverthat recirculated air is being used and that fresh airneeds to be provided after 20 minutes.

    If fresh air is not provided after 20 minutes, ProvideFresh Air is displayed. It displays for seven secondsapproximately every four minutes until the driver se-lects fresh air on the fresh/air recirculation switch orrotates the air circulation switch away from maximumair conditioning. See Chapter 4 for detailed operatinginstructions for the heater/air conditioner.

    Low Fuel LevelThe ICU continuously monitors fuel level. When thefuel level drops to 1/8th full, the word Warningflashes on the message display screen above thelow fuel alert.

When the batteries are charging, themeter needle moves to the plus side of the gauge;when the batteries are being discharged, the needlemoves to the minus side. A consistent negative read-ing when the engine is running indicates a possibleproblem with the charging system.

    Application Air Pressure GaugeAn application air pressure gauge registers the airpressure being used to apply the brakes, and shouldbe used for reference only. The gauge will not regis-ter air pressure until the foot brake pedal is de-pressed or the trailer hand brake is applied.

    Coolant Temperature Gauge

    NOTICEA sudden increase in coolant temperature mayindicate engine or cooling system failure. Bringthe vehicle to a safe stop and investigate thecause to prevent further damage. Do not operatethe engine until the cause has been determinedand corrected.During normal engine operation, the coolant tem-perature gauge should read between 175 and 195F(79 and 91C). If the temperature remains below160F (71C), inspect the cooling system to deter-mine the cause.If the temperature exceeds the maximum tempera-ture shown in Table 2.3, inspect the cooling systemto determine the cause. See the Century ClassTrucks Workshop Manual for troubleshooting andrepair procedures.

    If coolant temperature rises above the maximumtemperature listed in Table 2.3 on EPA07 engines,the CHECK engine lamp will illuminate. If the condi-

    tion does not improve, the STOP engine lamp willalso illuminate and an audible warning will sound.The engine will then derate or shut down, dependingon the type of engine protection system installed.

    Drive Axle Oil Temperature Gauges

    NOTICEA sudden increase in oil temperature that is notcaused by a load increase may indicate mechani-cal failure. Bring the vehicle to a safe stop andinvestigate the cause to prevent further damage.Do not operate the vehicle until the cause hasbeen determined and corrected.During normal operation, drive axle oil temperaturegauges should read as follows:

    160 to 220F (71 to 104C) for Detroit andMeritor drive axles

    180 to 200F (82 to 93C) for Dana Spicerdrive axles

    Under heavy loads, such as when climbing steepgrades, temperatures that exceed the normal oil tem-perature range for a short period are not unusual. Ifthe temperature returns to normal when the load de-creases, there is no problem.

    Engine Oil Pressure Gauge

    NOTICEA sudden decrease or absence of oil pressuremay indicate mechanical failure. Bring the vehicleto a safe stop and investigate the cause to pre-vent further damage. Do not operate the engineuntil the cause has been determined and cor-rected.The engine oil pressure gauge displays the currentengine oil pressure. If engine oil pressure falls belowthe minimum levels shown in Table 2.4, the CHECKengine lamp will illuminate. If the condition does notimprove, the STOP engine lamp will also illuminateand an audible warning will sound. The engine willthen derate or shut down, depending on the type ofengine protection system installed.

    Under heavy loads, such as when climbing steepgrades, temperatures that exceed the normal oil tem-perature range for a short period are not unusual. Ifthe temperature returns to normal when the load de-creases, there is no problem.

    Fuel GaugeThe fuel gauge indicates the level of fuel in the fueltank(s). A single fuel gauge is standard. If equippedwith an optional second fuel tank, each fuel tanklevel is indicated on a separate gauge.

    Primary and Secondary Air PressureGauges

    WARNINGIf air pressure falls below minimum pressure, thebraking ability of the vehicle will be limited. Slowthe vehicle down and bring it to a gradual stop.Do not attempt to move the vehicle until air pres-sure has risen above the minimum level. Movinga vehicle without adequate braking power couldcause an accident resulting in property damage,personal injury, or death.Air pressure gauges register the pressure in the pri-mary and secondary air systems. Normal pressure,with the engine running, is 100 to 120 psi (689 to827 kPa) in both systems.A low-air-pressure warning light and audible alert,connected to both the primary and secondary sys-tems, activate when air pressure in either systemdrops below 64 to 76 psi (441 to 524 kPa).When the engine is started, the warning light andaudible warning remain on until air pressure in bothsystems exceeds minimum pressure.

    PyrometerA pyrometer registers the exhaust temperature nearthe turbocharger. Variations in engine load can causeexhaust temperatures to vary. If the pyrometer read-ing shows that exhaust temperature exceeds normal,reduce fuel to the engine until the exhaust tempera-ture is reduced. Shift to a lower gear if the engine isoverloaded.

    SpeedometerThe speedometer registers speed in both miles perhour (mph) and kilometers per hour (km/h).TachometerThe tachometer indicates engine speed in revolutionsper minute (rpm) and serves as a guide for shiftingthe transmission and keeping the engine in the ap-propriate rpm range. For low idle and rated rpm, seethe engine identification plate.

  • Transmission Fluid TemperatureGaugeThe transmission fluid temperature gauge indicatesthe transmission lubricant operating temperature.Temperatures vary by application, but the transmis-sion fluid temperature gauge reading should not ex-ceed 250F (121C).Under heavy loads, such as when climbing steepgrades, temperatures that exceed the normal oil tem-perature range for a short period are not unusual. Ifthe temperature returns to normal when the load de-creases, there is no problem.

    NOTICEA sudden increase in transmission fluid tempera-ture that is not caused by a load increase mayindicate mechanical failure. Bring the vehicle to asafe stop and investigate the cause to preventfurther damage. Do not operate the vehicle untilthe cause has been determined and corrected.

    Turbocharger Boost Pressure GaugeA turbocharger boost pressure gauge indicates thepressure in the intake manifold, in excess of atmos-pheric pressure, being created by the turbocharger.

    VoltmeterThe voltmeter indicates the vehicle charging systemvoltage when the engine is running and the batteryvoltage when the engine is off. By monitoring thevoltmeter, the driver can stay aware of potential bat-tery charging problems and have them fixed beforethe batteries discharge enough to create starting diffi-culties. Vehicles are equipped with either a voltmetergauge, or a digital voltmeter readout located on thebottom line of the dash message center.The voltmeter will normally show approximately 13.7to 14.1 volts when the engine is running. The voltageof a fully charged battery is 12.7 to 12.8 volts whenthe engine is off. Battery voltage under 12.0 volts isconsidered a low battery, and a completely dis-charged battery will produce only about 11.0 volts.If the voltmeter shows an undercharged or over-charged condition for an extended period, have thecharging system and batteries checked at an autho-rized Freightliner service facility.

    On a vehicle equipped with a battery isolator system,the voltmeter measures the average voltage of all thebatteries when the engine is running. When the en-gine is off, the voltmeter shows only the isolated bat-tery voltage and does not indicate the voltage of theengine-starting batteries.

    ControlsControls and switches are listed here in alphabeticalorder.

    Roll Stability AdvisorIMPORTANT: This is not an advance warningsystem. The roll stability advisor displays a mes-sage only after the driving maneuver is com-pleted.The roll stability system uses a lateral-accelerationsensor that monitors rollover risk. Shortly after acurve, lane change, or other driving maneuver thatresults in a rollover-risk detection, a dash warninglight illuminates, an audible tone sounds, and a driveradvisory message is displayed in the driver message

    center. The purpose is to advise the driver that theprevious maneuver produced a rollover risk.The roll stability advisor displays different text mes-sages depending on the severity of the risk of eachoccurrence of risky driving. From the highest risklevel to the lowest risk level, the system will soundan audible alert, and display a message, as shown inFig. 2.30.NOTE: The system will calculate and recom-mend a speed reduction value. It may be differ-ent than the values shown here.Bring the vehicle to an authorized service facility if asystem failure message is displayed.

    Roll Stability Control

    WARNINGThe Roll Stability Control system is intended onlyas an aid for a conscientious and alert driver.Carefully read the information in this manual tounderstand this system and its limitations. TheRoll Stability Control system is not a substitutefor safe driving procedures. Failure to drivesafely, and use the system properly, could resultin personal injury and/or death and propertydamage.The roll stability control system automatically reducesengine power, applies the engine brake, and/or ap-plies the tractor and trailer brakes when the accelera-tion sensor detects that the vehicle is at risk of rollingover. The control can intervene even before an advi-sory message is displayed.The dash indicator light illuminates whenever the rollstability control system intervenes.

    Hard-Braking AdvisorThe hard-braking advisor uses the information fromthe ABS wheel speed sensors to determine whenbraking is severe enough to produce lockup at oneor more wheels on the tractor, and/or very rapid ve-hicle deceleration. Shortly after a hard-braking eventoccurs, an advisory message is displayed in thedriver message center, indicating that the brakingbehavior was too aggressive for the current road sur-face conditions. This system is not a replacement fora drivers good judgment. Sometimes it is necessaryto brake hard.
