Charging and fitting the battery
G Risk of injury
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 it is still installed. Otherwise, the vehi-
cle's electronic system may be damaged.
Only charge the battery in a well-ventilated
area. As the battery is being charged, gases
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.
Practical advice

There is a risk of acid burns during the
