Charging
GWARNING
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.
If the indicator/warning lamps do not light up in the instrument cluster when temperatures are
low, it is probably because the discharged bat-
tery 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 behavior may deteriorate, in particular
at low temperatures. Have the thawed battery
checked at a qualified specialist workshop.
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
!Only charge the installed battery with a bat-
tery charger that has been tested and
approved by Mercedes-Benz. This device
