HEnvironmental note
Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in an
environmentally 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 batter-
ies.
!Have the battery regularly checked at aqualified specialist workshop.
Comply with the service intervals in the Main-tenance Booklet, or contact a qualified spe-cialist workshop for more information.
!You should have all work involving the bat-tery carried out at a qualified specialist work-shop. In the exceptional case that it is neces-sary for you to disconnect the battery your-self, make sure that:
Rswitch off the engine and remove theSmartKey. On vehicles with KEYLESS-GO,make sure that the ignition is switched off.Check that all the indicator lamps in theinstrument cluster are off. Otherwise, elec-tronic components, such as the alternator,may be damaged.
Ryou first remove the negative terminalclamp and then the positive terminalclamp. Never swap the terminal clamps.Otherwise, the vehicle's electronic systemmay be damaged.
Rin vehicles with automatic transmission,the transmission is locked in position]after the battery is disconnected. The vehi-cle is secured against rolling away. You canthen no longer move the vehicle.
The battery and the cover of the positive ter-minal clamp must be installed securely duringoperation.
Comply with safety precautions and take pro-tective measures when handling batteries.
Risk of explosion.
Fire, open flames and smoking areprohibited when handling the bat-tery. Avoid creating sparks.
Battery acid is caustic. Avoid contactwith skin, eyes or clothing.
Wear suitable protective clothing,especially gloves, apron and face-guard.
Rinse any acid spills immediatelywith clear water. Contact a physicianif 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 havebeen tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns should thebattery be damaged in the event of an accident.
In order for the battery to achieve the maximumpossible service life, it must always be suffi-ciently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehicle.In this case, have the battery disconnected at aqualified specialist workshop. You can alsocharge the battery with a charger recommendedby Mercedes-Benz. Contact a qualified special-ist workshop for further information.
Have the battery condition of charge checkedmore frequently if you use the vehicle mainly forshort trips or if you leave it standing idle for alengthy period. Consult a qualified specialistworkshop if you wish to leave your vehicleparked for a long period of time.
280Battery (vehicle)
Breakdown assistance

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
