Charging and fitting the battery
page 62) in
G Risk of injury
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.
G Risk of injury
There is a risk of acid burns during the
charging process due to the gases which
escape from the battery. Do not lean over
the battery during the charging process.
