2019 MERCEDES-BENZ E CLASS engine

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.
