can escape and generate minor explosions.
This may injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be
charged when still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. G

charging process due to the gases which
escape from the battery. Do not lean over
the battery during the charging process. G
Risk of injury
Battery acid is caustic. Avoid contact with
the skin, eyes or clothing.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. These battery
chargers allow the battery to be charged
while it is still installed. However, the bat-
tery must always be disconnected first.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
X Charge the battery. Observe the notes in
the operating instructions for your battery
