If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R Jump-starting may only be performed when
the engine and catalytic converter are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R Jump-starting may only be performed with
batteries that have the same nominal volt-
age.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal and further information
about jump-starting can be obtained from
any Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts. Only use the jump-starting pro-
cedure for the battery in the engine com-
partment. Do not use a rapid-charging device to start
the engine. G
Risk of injury
There is a risk of acid burns when jump-
starting a vehicle due to the gases which
escape from the battery. Do not lean over
the battery while the engine is being jump-
started. G
Risk of explosion
Gases escaping from the battery during
jump-starting may cause minor explosions.
Avoid creating sparks. Keep naked flames
away from the battery, and do not smoke.
Comply with safety precautions and take
protective measures when handling batter-
ies. You will find these under "Battery" in
the index.
