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 battery using the jump-
starting connection point.
!
Only use battery chargers with a maximum
charging voltage of 14.8 V.
!
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.
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do not
light up, it is highly likely that the discharged
battery has frozen. In this case you may neither
jump-start the vehicle nor charge the battery.
The service life of a thawed-out battery may be
shorter. The starting characteristics can be
impaired, particularly at low temperatures. Have
the thawed-out battery checked at a qualified
specialist workshop.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Contact an authorized Mercedes-
Benz Center for information and availability.
Charge the battery in accordance with the oper-
ating instructions for the battery charger.
