When charging using a battery charger without a maximum charging voltage, the battery or the on-board electronics may be damaged.
When using a battery charger without a maximum charging voltage, the battery or the vehicle electronics may be damaged.
A battery generates hydrogen gas during the charging process. If there is a short circuit or sparks start to form, there is a danger of the hydrogen gas igniting.
During the charging process and starting assistance, the battery may release an explosive gas mixture.
If the indicator/warning lamps in the instrument cluster do not light up at low temperatures, it is very likely that the discharged battery has frozen.
A discharged battery may freeze at temperatures slightly above or below freezing point.
During starting assistance or battery charging, battery gas may be released.
Charging the battery at very low temperatures may shorten the service life of the battery and have a negative effect on starting.
It is recommended that you have the thawed battery checked at a qualified specialist workshop.
Numerous or extended attempts to start the engine may damage the catalytic converter due to non-combusted fuel.
Only use undamaged jump leads/charging cables with a sufficient cross-section and insulated terminal clamps.
Non-insulated parts of the terminal clamps must not come into contact with other metal parts while the jump lead/charging cable is connected to the battery/jump-start connection point.
The jump lead/charging cable must not come into contact with any parts which may move when the engine is running.
Always make sure that neither you nor the battery is electrostatically charged.
Keep away from fire and naked flames.
Do not lean over the battery.
When charging: only use battery chargers tested and approved by Mercedes-Benz and read the battery charger's operating instructions before charging the battery.
Starting assistance may only be provided using batteries with a nominal voltage of 12 V.
The vehicles must not touch.
Petrol engine: Only accept starting assistance if the engine and exhaust system are cold.
When the starting assistance/charging process is complete:
You can obtain further information on starting assistance at any qualified specialist workshop.
