Jump Starting - Mercedes-Benz Citan 2015 Operating Instructions Manual

Jump-starting
G
WARNING
If the ECO start/stop function is activated, the engine can be started unintentionally, e.g. by
accidentally depressing the clutch pedal. If work is being carried out on the engine under these
circumstances, there is a risk of injury from moving engine parts.
Deactivate the ECO start/stop function before work is carried out on the engine.
G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over
the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clean water and seek medical attention at once.
G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a risk
of an explosion.
Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over a battery.
G
WARNING
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks
are created, the hydrogen gas can ignite. There is a risk of an explosion.
Make sure that the positive terminal of a connected battery does not come into contact with
R
vehicle parts.
Never place metal objects or tools on a battery.
R
It is important that you observe the described order of the battery terminals when connecting
R
and disconnecting a battery.

WARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Vehicles with a petrol engine: avoid repeated and lengthy starting attempts. Otherwise, the
non-combusted fuel may damage the catalytic converter.
If the indicator/warning lamps do not light up in the instrument cluster when temperatures are low,
it is probably because the discharged battery has frozen. Should this be the case, do not jump-start
the vehicle or charge the battery. The service life of a thawed battery may be shorter. Start-up
behaviour may deteriorate, in particular at low temperatures. Have the thawed battery checked at
a qualified specialist workshop.
