#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.
