Maintenance and care

Only replace a battery with a battery that hasbeen recommended by Mercedes-Benz.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy, thusconserving battery power.
If the power supply has been interrupted, e.g. ifyou reconnect the battery, you will have to:
Rset the clock using the multimedia system(see the Digital Operator's Manual)
Rreset the function for folding the exterior mir-rors in/out automatically, by folding the mir-rors out once (Ypage 98)
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 sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
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 batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
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 (Ypage 282).
XOpen the hood.
XConnect the battery charger to the positiveterminal and ground point in the same orderas when connecting the donor battery in thejump-starting procedure (Ypage 282).
If the indicator/warning lamps do not light up inthe instrument cluster at low temperatures, it isvery likely that the discharged battery has fro-zen. In this case you may neither jump-start thevehicle nor charge the battery. The service life ofa thawed-out battery may be shorter. The start-ing characteristics can be impaired, particularlyat low temperatures. Have the thawed-out bat-tery checked at a qualified specialist workshop.
Only charge the installed battery with a batterycharger which has been tested and approved byMercedes-Benz. A battery charger unit speciallyadapted for Mercedes-Benz vehicles and testedand approved by Mercedes-Benz is available asan accessory. It permits the charging of the bat-tery in its installed position. Contact an author-ized Mercedes-Benz Center for further informa-tion and availability. Read the battery charger'soperating instructions before charging the bat-tery.
Replacing the 12 V battery
Observe the notes on the 12 V battery(Ypage 279).
Mercedes-Benz recommends that you have the12 V battery replaced at a qualified specialistworkshop, e.g. at an authorized Mercedes-BenzCenter.
If you want to replace the battery yourself,observe the following notes:
RAlways replace a defective battery with a bat-tery which meets the specific requirements ofthe vehicle.
The vehicle is equipped with a battery usingAGM (absorbent glass mat) technology or abattery using EFB (enhanced flooded battery)technology. Full vehicle functionality is guar-anteed only with an AGM or EFB battery. Ifreplacement is necessary, always use the bat-tery technology originally installed. Switchingbetween the battery technologies is not per-mitted. For safety reasons, Mercedes-Benzrecommends that you only use batteries

If the indicator/warning lamps do not light up in the instrument cluster at low temperatures, it is verylikely that the discharged battery has frozen. In this case you may neither jump-start the vehicle norcharge the battery. Let the battery thaw first. The service life of a thawed-out battery may be shorter.The starting characteristics can be impaired, particularly at low temperatures. Have the thawed-outbattery checked at a qualified specialist workshop.
Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, theengine can be jump-started from another vehicle or from a second battery using jumper cables.Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-start the vehicle using a second battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables that are not damaged and have a sufficient cross-section and insulatedterminal clamps.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RNon-insulated parts of the terminal clamps do not come into contact with other metal parts whilethe jumper cables are connected to the battery.
