Contact a qualified specialist work-shop which has the necessary specialistknowledge and tools to carry out the workrequired. Mercedes-Benz recommends thatyou use an authorized Mercedes-Benz Centerfor this purpose.

Operator's Manual

Vehicle equipmentThis Supplement provides information on all theimportant functions of your hybrid vehicle thatare either not described or differ from thedescriptions in the vehicle Operator's Manual.The information supplements or substitutes thecorresponding sections in the vehicle Opera-tor's Manual. Under no circumstances does thesupplement replace the Operator's Manual.This Supplement describes all models, andstandard and optional equipment for your sys-tem, as available at the time of going to print.Country-specific differences are possible. Bearin mind that your vehicle may not feature allfunctions described here. This also applies tosafety-relevant systems and functions. Theequipment in your vehicle may therefore differfrom that shown in the descriptions and illus-trations.The original purchase contract documentationfor your vehicle contains a list of all the systemsin your vehicle.Should you have any questions concerningequipment and operation, please consult aqualified specialist workshop.The Operator's Manual and Maintenance Book-let are important documents and should be keptin the vehicle.

Operating safety

Important safety notesHybrid vehicles have a combustion engine andan electric motor. The voltage supply for oper-

ating the vehicle electrically is provided by thevehicle's high-voltage electrical system of thehybrid drive system.

G DANGERThe vehicle's high-voltage electrical system isunder high voltage. If you modify componentsin the vehicle's high-voltage electrical systemor touch damaged components, you may beelectrocuted. The components in the vehi-cle's high-voltage electrical system may bedamaged in an accident, although the damageis not visible. There is a risk of fatal injury.Following an accident, do not touch any high-voltage components and never modify thevehicle's high-voltage electrical system. Havethe vehicle towed away after an accident andthe vehicle's high-voltage electrical systemchecked by a qualified specialist workshop.

All components of the hybrid drive system aremarked with yellow warning stickers that warnyou of the danger of high voltage. The cables ofthe vehicle's high-voltage electrical system areorange in color.Always have all work on the hybrid drive systemcarried out at a qualified specialist workshop.Vehicles with an electric motor generate muchless driving noise than vehicles with internalcombustion engines. As a result, your vehiclemay not be heard by other road users in certainsituations. This can happen, for example, whenyou are parking and your vehicle is not seen byother road users. This requires you to adopt aparticularly anticipatory driving style, as it isnecessary to allow for the possibility that otherroad users may behave erratically.

Important safety notes

Danger of electric shock


When towing a vehicle after an accident, be sureto observe the following sections in the vehicleOperator's Manual:RTransporting the vehicleRTowing the vehicle with the rear axle raisedRTowing a vehicle with both axles on theground

Read the safety instructions on towing and tow-starting (Y page 53).

All components of the hybrid drive system aremarked with yellow warning stickers that warnyou of the danger of high voltage. The cables ofthe vehicle's high-voltage electrical system areorange in color.The ignition must be switched off when carryingout general tasks, such as replacing bulbs orchecking the coolant level.

Automatic switching off of the hybriddrive systemIf components of the restraint system are acti-vated during an accident, the hybrid drive sys-tem is automatically deactivated.The hybrid drive system is not activated whenthe vehicle is started if:Ran electrical short circuit is detected in thehybrid drive systemRan electrical connection in the hybrid drivesystem is disconnected

This ensures that you do not come into contactwith high voltage.

Manual switching off of the hybrid drivesystemThe hybrid drive system can be deactivatedmanually using the high voltage switch-offdevice.

! To prevent damage to the hybrid drive sys-tem please observe the following instruc-tions:Ronly deactivate the hybrid drive systemmanually in the following situations.Rwork on the hybrid drive system may onlybe carried out at a qualified specialist work-shop, even when it has been deactivatedmanually.

Deactivate the hybrid system manually if:Rthe6 restraint systemwarning lamp in theinstrument cluster lights up after an accidentRthe vehicle is badly damaged, e.g. after anaccident, and the restraint system compo-nents were not activatedRthe vehicle is badly damaged and has to betowed or transported

Points to remember

General notesHybrid technology combines a fuel-efficientcombustion engine with a powerful electricmotor. In HYBRID operating mode, the hybriddrive systemautomatically selects themost effi-cient operating mode for every driving situation.Drive the vehicle in the usual manner.To save fuel in HYBRID mode, the hybrid drivesystem switches off the combustion engine asoften as possible during the journeywhen poweroutput requirements are low. When power out-put requirements are low, the electric motorpowers the vehicle. The engine is switched on,even while the vehicle is in motion, when ahigher power output is required. The engine isusually switched off when the vehicle is station-ary. Consequently, there is usually no engineidling as with combustion engine vehicles.For pulling away and accelerating, the electricmotor supports the internal combustion engineusing the power stored in the high-voltage bat-tery. In addition, the power is used for electricdriving, operation of the electric refrigerantcompressor and to supply the 12 V on-boardelectrical system. In this way the hybrid drivesystem helps to reduce your vehicle's fuel con-sumption.Observe the driving tips on plug-in-hybrid oper-ation (Y page 26).

Recuperative Brake SystemIf you release the accelerator pedal when thevehicle is in motion, recuperation is initiated.The electric motor is operating as a generator,e.g. in overrun mode and when braking. Hybridtechnology converts the kinetic energy of thevehicle to electric energy and stores it in thehigh-voltage battery.Observe the important safety notes for theRecuperative Brake System (Y page 11).

Important safety notesIf the engine is switched off by the ECO start/stop function, you open the driver's door andunfasten your seat belt:Ra message appears in the multifunction dis-play andRa warning tone soundsFurther information (Y page 45).All of the vehicle's systems remain active, if:Rthe vehicle is stationaryRthe combustion engine is switched off andRtheõ indicator lights up in the instrumentcluster

If you remove your foot from the brake pedalwhile in transmission positionh ork, thevehicle could pull away automatically.Observe the notes on theõ indicator of theECO start/stop function (Y page 23).Vehicles with an electric motor generate muchless driving noise than vehicles with internalcombustion engines. As a result, your vehiclemay not be heard by other road users in certainsituations.The vehicle is equipped with the acoustic pres-ence indicator.The acoustic presence indicator generates asound at speeds between 0 and 20 mph(30 km/h). This helps other road users, partic-ularly pedestrians and cyclists, to hear yourvehicle better. This noise can also be heardwithin the vehicle interior in a quiet environ-ment, for example.The volume depends on the engine speed. Thefaster you accelerate, the louder the sound is. Itis reduced at speeds between 12 and 18 mph(20 to 30 km/h) and is switched off when aspeed of 20 mph (30 km/h) is reached. Abovethis speed, normal vehicle noise emission is suf-ficient for the vehicle to be heard in good time byother road users.

Starting the engineThe vehicle starts in electric mode without theinternal combustion engine (noiseless start).The internal combustion engine starts only afterthe power demanded by the driver exceeds theavailable power that the electric motor can cur-rently provide.Noiseless start operation is dependent on theoutside temperature and the operating temper-ature of the internal combustion engine. If not allconditions for noiseless start operation are ful-filled, the vehicle starts with the internal com-bustion engine.Observe the notes on starting the vehicle in thevehicle Operator's Manual.

Overrun modeIn overrun mode, the combustion engine isswitched off and is disconnected from the drivetrain. The electric motor:Rgenerates low thrust, which corresponds tothe overrun mode of an active combustionengineRfunctions as an alternator, produces the nec-essary energy for the auxiliary consumers andcharges the high-voltage battery

Overrun mode is available in the Comfort driveprogram at speeds below 80 mph (130 km/h).

Route-based operating strategyFor the route-based operating strategy, the sys-tem factors in information about the expectedroute when route guidance is active.The information on the route is provided by themultimedia system and includes the following:Rroad typesRspeed limitationsThe use of electric energy is automatically opti-mally distributed from the beginning to the endof the journey, using map data. The distributionis pre-emptive and takes into consideration:Rthe sections of the journey aheadRthe energy consumption on the whole route

The condition of charge of the high-voltage bat-tery is thus systematically controlled. In addi-tion, the control function takes into accountthat:Rthe fuel savings through the use of electricalenergy can vary, depending on the route (e.g.urban, interurban or highway)Rthe use of electrical energy is held availablefor electric driving, particularly for urbanroutes

The vehicle thus automatically selects the opti-mum driving mode for the respective section ofthe route.The route-based operating strategy is availableunder the following conditions:Rthe Individual drive program is selectedRthe ECO setting is selected under Drive in theIndividual drive programRthe HYBRID operating mode is selectedRactive route guidance is activatedRsuitable map data is availableWhen the route-based operating strategy isbeing used, the area in front of the vehicle isshown as green in the multifunction display.

Driving tips

General driving tipsDrive carefully and maintain a safe distancefrom the vehicle in front. Avoid frequent andsudden acceleration as well as abrupt braking.During partial electric driving, pulling away andacceleration, the electric motor supports theinternal combustion engine.During overrun mode in transmission positionh and when braking, the electric motor oper-ates as an alternator.Further information on the ECO start/stop func-tion (Y page 23).You can find further driving tips in the vehicleOperator's Manual.

Stationary vehicleIf the vehicle is stopped, the combustion engineis, for the most part, switched off. Automaticclimate control continues to function. The elec-tromechanically assisted steering gear allowsyou to use the power steering without reducedcomfort.

AccelerationDepending on the operating mode, under lowload conditions, pulling away and driving areperformed:Rentirely by electric propulsionRin combination with the internal combustionengine

When accelerating at an increased or full load,boost mode is utilized. The electric motor sup-ports the combustion engine by providing addi-tional drive torque.

Overrun mode or brakingThere are three possible operating modes whenthe hybrid vehicle is decelerating:Rwhen coasting and decelerating, energy recu-peration is already taking place (Y page 20).The electric motor operates as a generatorand stores the recovered energy in the high-voltage battery.Rwhen the brakes are applied lightly, the vehi-cle is slowed down further by the electricmotor. Energy recuperation is increased(Y page 20). The electric motor operates as agenerator and stores the recovered energy inthe high-voltage battery.Rduring heavy braking, the service brake is alsoused to slow down the vehicle. The two sys-tems work together.

26 Driving tipsDrivingandparking

Urban drivingIn city traffic, energy is recuperated during fre-quent deceleration phases.The vehicle can be driven by the electric motoralone up to a speed of approximately 80 mph(130 km/h).The vehicle is driven by the electric motor aloneonly when all conditions for the automaticengine switch-off are fulfilled.Further information on the automatic engineswitch-off (Y page 23).

Driving on inter-urban roadsThe following phases are possible when drivingon inter-urban roads:Rrapid acceleration (boost mode)RrecuperationRelectric operation modeThe vehicle can be driven by the electric motoralone up to a speed of approximately 74 mph(120 km/h).A great deal of recovered energy may be avail-able, depending on the route profile. Thisreduces consumption and emissions.

Highway drivingWhen driving on a highway, switching off thecombustion engine has a particularly positiveeffect on fuel consumption and emissions.If the driver removes his/her foot from theaccelerator pedal in the Comfort drive programand a speed of 80mph (130 km/h) is not excee-ded, the combustion engine is automaticallyswitched off.Further information on the automatic engineswitch-off (Y page 23).

Battery (vehicle)

Important safety notesYour vehicle is equipped with a 12 V battery anda high-voltage battery.For the 12 V battery, observe the notes under"Battery (vehicle)" in the vehicle Operator'sManual.


G WARNINGIn the event of a vehicle fire, the internal pres-sure of the high-voltage battery could exceeda critical value. In this case, flammable gasescapes through a vent valve in the vehicle'sunderbody. The gas could ignite. There is arisk of injury.In cases of unusual smells developing, smokeor burn marks, stop the charging processimmediately.Leave the danger area immediately. Securethe danger area at a suitable distance.Contact a qualified specialist workshop.

G WARNINGIf the housing of the high-voltage battery hasbeen damaged, electrolyte and gases mayleak out. These are poisonous and caustic.There is a risk of injury.Avoid contact with skin, eyes or clothing.Immediately rinse electrolyte splashes off

with water and seek medical attentionstraight away.

! Exhaustive discharge caused by the vehiclestanding idle for lengthy periods can damagethe high-voltage battery. If the vehicle is idlefor lengthy periods leave the high-voltage bat-tery connected to a charging station.

If the battery charge is sufficient, the high-volt-age battery can also supply the 12V batterywithenergy. This happens only if the battery chargeof the 12 V battery requires this, e.g. after usingelectrical consumers for an extended periodwith the engine switched off. As the on-boardvoltage is continuously monitored this can alsobe performed when the engine is switched off.The battery charge of the 12 V battery and theon-board voltage are thereby kept stable forlonger.Consult a qualified specialist workshop if youwish to leave your vehicle parked for a longperiod of time.

Charging the high-voltage batterywhile the vehicle is stationary

G DANGERCombustion engines emit poisonous exhaustgases such as carbon monoxide. Inhalingthese exhaust gases is hazardous to healthand can result in poisoning. There is a risk offatal injury. Therefore, never leave the enginerunning in an enclosed space without ade-quate ventilation.

! Only charge the high-voltage battery in the"Charging when stationary" mode. Do notconnect any battery chargers to the high-volt-age battery. This could damage the vehicle’shigh-voltage electrical system.

X Bring the vehicle to a stop with the enginerunning.The engine powers the electric motor. Theelectric motor operates as an alternator. Thehigh-voltage battery is being charged.

If the high-voltage battery has been dischargedexcessively, charge the high-voltage battery toat least 60%. In the "Charging when stationary"operating mode, you can observe the conditionof charge of the high-voltage battery up to a

Jump-starting

Observe the notes on jump-starting in the vehi-cle Operator's Manual.If your vehicle has been jump-started, the elec-tric drive may not be available for approximately30 minutes.Jump-starting is not considered to be a normaloperating condition.Jumper cables and further information regardingjump-starting can be obtained at any qualifiedspecialist workshop.

Towing

Important safety notesObserve the notes on towing and transporting inthe vehicle Operator's Manual.Towing the vehicle with the rear axle raised ortransporting the vehicle should only be carriedout by professional recovery companies. It isbetter to have the vehicle transported than tohave it towed away.In the following cases, the vehicle must not betowed but be transported instead:Rthe multifunction display is not workingRtheá Towing Not Permitted SeeTowing Not Permitted SeeOperator's ManualOperator's Manual message is shown inthe multifunction display

If the vehicle is in a dangerous area, it can betowed out of that area with both axles on theground. In this case, the towing distance mustnot be greater than 165 ft (50 m) and must notexceed a towing speed of 6 mph (10 km/h). Forlonger distances, have the vehicle loaded andtransported.
