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.
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.
378Breakdown 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.

Observethefollowing points duringstartingassistance and whenchargingthe battery:
ROnly use undamaged jumper cables/charg‐ing cables with a sufficient cross-section andinsulatedterminal clamps.
RNon-insulated parts oftheterminal clampsmust not come into contact withother metalparts whilethe jumper cable/charging cableis connectedtothe battery/jump-startcon‐nection point.
RThe jumper cable/charging cable must notcome into contact withany parts which maymovewhenthe engine isrunning.
RAlways make surethat neitheryou northebattery is electrostaticallycharged.
