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.

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

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing 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.
!
Only charge the installed battery with a bat-
tery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged while
still installed in the vehicle.
!
Only use battery chargers with a maximum
charging voltage of 14.8 V.
!
Only charge the battery using the jump-start
connection point.
The jump-starting connection point is in the
engine compartment.
If the indicator/warning lamps do not light up at
low temperatures, it is very likely that the dis-
charged battery has frozen. In this case you may
neither jump-start the vehicle nor charge the
Battery (vehicle)
battery. The service life of a battery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at a qualified specialist workshop.
Read the battery charger's operating instruc-
tions before charging the battery.
Open the bonnet.
