Notes onstarting assistance and oncharg‐ingthe12V battery
Vehicles with a lithium-ion batteryWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
NOTEDamagetothe battery fromover‐voltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthe on-board electronics may be damaged.
Only use batterychargerswith a maxi‐mumchargingvoltage of14.4V.
AllothervehiclesWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
NOTEDamagingthe batterythroughovervoltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthevehicle electronics may be damaged.
Only use batterychargerswith a maxi‐mumchargingvoltage of14.8V.
\nWARNINGRisk ofexplosion fromhydro‐gengas igniting
A batterygenerateshydrogengas duringthecharging process. Ifthere is a short circuit orsparksstarttoform,there is a danger ofthehydrogengas igniting.
Make surethatthe positiveterminal ofthe connected battery does not comeinto contact withvehicle parts.
Never place metal objects ortools on abattery.
When connecting and disconnectingthebattery,you must observethe descri‐bed orderforthe battery clamps.
372Breakdown assistance

When givingstarting assistance, alwaysmake surethatyou onlyconnect bat‐teryterminals with identical polarity.
Duringstarting assistance,you mustobservethe described orderfor con‐necting and disconnectingthe jumpercables.
Do not connect or disconnectthe bat‐teryclamps whilethe engine isrunning.
\nWARNINGRisk ofexplosion duringcharging process andstarting assistance
Duringthecharging process andstartingassistance,the battery mayrelease anexplo‐sivegas mixture.
Avoidfire, openflames, creating sparksand smoking.
Make surethatthere is sufficientventi‐lation duringthecharging process andduringstarting assistance.
Do not leanover a battery.
\nWARNINGRisk ofexplosion from a fro‐zen battery
A discharged battery may freeze attempera‐tures slightly aboveor below freezing point.
Duringstarting assistance or batterycharg‐ing, batterygas may bereleased.
Alwaysthawa frozen batteryoutfirstbeforecharging it or performingstart‐ing assistance.
Ifthe indicator/warning lamps inthe instrumentcluster do not light up at lowtemperatures, it isverylikelythatthe discharged battery has fro‐zen. Inthis caseyou may neither jump-startthevehicle norchargethe battery.
The service life of a batterythat has beenthawed may be dramatically shortened. Thestartingcharacteristics may be impaired, espe‐cially at lowtemperatures.
It isrecommendedthatyou haveathawed bat‐terychecked at aqualified specialistworkshop.

Replacing the12V battery
Observethe notes onthe12V battery(→page370).
Mercedes-Benzrecommendsthatyou havethe12V batteryreplaced at aqualified specialistworkshop, e.g. at an authorized Mercedes-BenzCenter.
Observethefollowing notes ifyouwanttoreplacethe batteryyourself:
RAlwaysreplace afaulty batterywith a batterywhich meetsthe specificvehiclerequire‐ments.
Thevehicle is equipped with anAGMtechnol‐ogy battery (Absorbent Glass Mat) or a lith‐ium-ion battery.Fullvehicle functionality is
only guaranteed with anAGM battery or lith‐ium-ion battery.For safetyreasons,Mercedes-Benzrecommendsthatyou onlyuse batteries which havebeentested andapprovedforyourvehiclebyMercedes-Benz.
RCarryover detachable parts, such asventhoses, elbowfitting orterminal coversfromthe battery beingreplaced.
RMake surethatthevent hose is alwayscon‐nectedtothe original opening onthe side ofthe battery.
