Rremove the SmartKey from the ignition lock
The interior lighting is switched on for a settime when the SmartKey is removed from theignition lock. You can activate this delayedswitch-off using the on-board computer(Ypage 201).
Replacing bulbs
The front and rear lamps of your vehicle areequipped with LED bulbs. Do not replace thebulbs yourself. Contact a qualified specialistworkshop which has the necessary specialistknowledge and tools to carry out the workrequired.
Bulbs and lamps are an important aspect ofvehicle safety. You must therefore make surethat these function correctly at all times. Havethe headlamp setting checked regularly.
Windshield wipers
Switching the windshield wipers
on/off
!Do not operate the windshield wiperswhen the windshield is dry, as this could
damage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes place whenthe windshield is dry.
If it is necessary to switch on the windshieldwipers in dry weather conditions, always usewasher fluid when operating the windshieldwipers.
!If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluidafter washing the vehicle in an automaticcar wash.
!Intermittent wiping with rain sensor: dueto optical influences and the windshieldbecoming dirty in dry weather conditions,the windshield wipers may be activatedinadvertently. This could then damage thewindshield wiper blades or scratch the wind-shield.
For this reason, you should always switchoff the windshield wipers in dry weather.

GWARNING
Electrostatic build-up can lead to the crea-
tion of sparks, which could ignite the highly
explosive gases of a battery. There is a risk
of an explosion.
Before handling the battery, touch the vehi-
cle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms whencharging the battery as well as when jump-starting.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across thecarpet or other synthetic materials
Rif you wipe the battery with a cloth
GWARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit occurs
or sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objects or tools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting and disconnecting a bat-
tery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
HEnvironmental note
Batteries contain pollutants.
It is illegal to dispose of
them with the household
rubbish. They must be col-
lected separately and dis-
posed of in an environmen-
tally responsible recycling
system.
Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used bat-
teries.

Battery acid is caustic. Avoid con-tact with skin, eyes or clothing.
Wear suitable protective clothing,especially gloves, apron and face-guard.
Rinse any acid spills immediatelywith clear water. Contact a physi-cian if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-mends that you only use batteries which have
been tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns shouldthe battery be damaged in the event of anaccident.
In order for the battery to achieve the maxi-mum possible service life, it must always besufficiently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehi-cle. In this case, have the battery disconnec-ted at a qualified specialist workshop. You canalso charge the battery with a charger recom-mended by Mercedes-Benz. Contact a quali-fied specialist workshop for further informa-tion.
Have the battery condition of charge checkedmore frequently if you use the vehicle mainlyfor short trips or if you leave it standing idlefor a lengthy period. Consult a qualified spe-cialist workshop if you wish to leave your vehi-cle parked for a long period of time.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy,thus conserving battery power.
After an interruption to the power supply, e.g.due to a discharged battery, you must resetthe clock (see the Digital Operator's Manual).
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over a battery.

ately with plenty of clean water and seek
medical attention.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a maximumcharging voltage of 14.8 V.
!Only charge the battery using the jump-starting connection point.
The jump-starting connection point is in theengine compartment.
If the indicator/warning lamps do not light upat low temperatures, it is very likely that thedischarged battery has frozen. In this case,you may neither charge the battery nor jump-start the vehicle. The service life of a thawed-out battery may be shorter. The starting char-acteristics can be impaired, particularly at lowtemperatures. Have the thawed-out batterychecked at a qualified specialist workshop.
Read the battery charger's operating instruc-tions before charging the battery.
XOpen the hood.
XConnect the battery charger to the positiveterminal and ground point in the same order
as when connecting the donor battery in thejump-starting procedure (Ypage 285).
Replacing the 12 V battery
Observe the notes on the 12 V battery(Ypage 282).
Mercedes-Benz recommends that you havethe 12 V battery replaced at a qualified spe-cialist workshop, e.g. at an authorizedMercedes-Benz Center.
If you want to replace the battery yourself,observe the following notes:
RAlways replace a defective battery with abattery which meets the specific require-ments of the vehicle.
The vehicle is equipped with an AGM(Absorbent Glass Mat) technology battery.Full vehicle functionality is only guaranteedwith an AGM battery. For safety reasons,Mercedes-Benz recommends that you onlyuse batteries which have been tested andapproved for your vehicle by Mercedes-Benz.
RUse detachable parts such as breatherhoses, angled connecting pieces or terminalcovers from the battery which is to bereplaced.
RMake sure that the vent hose is always con-nected to the original opening on the bat-tery side.
RInstall existing or supplied cell caps to pre-vent gases or battery acid from escaping.
RMake sure that the detachable parts areconnected again in the same way.
Jump-starting
For the jump-starting procedure, use only the jump-starting connection point in the engine com-partment, consisting of a positive terminal and a ground point.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the
