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.
&WARNINGRisk 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.
Breakdown assistance421

#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.
&WARNINGRisk 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.
&WARNINGRisk 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.

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.

#Duringstarting assistance:before discon‐nectingthe jumper cable, switch on an elec‐trical consumer inyourownvehicle, e.g.therear windowdefroster or lighting.
Whenthestarting assistance/charging processis complete:
#First,removethe jumper cable/chargingcable from ground point5and negativepole ofthe donor battery,then from positiveclamp4and positive pole ofthe donor bat‐
tery. Begin eachtime with the contacts onyourownvehiclefirst.
#Afterremovingthe jumper cable/chargingcable, close cover3of positive clamp4.
