Practical advice

Jump-starting

Jump-starting
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:
Jump-starting must only be performed
R
when the engine and catalytic converter
are cold.
Do not start the engine if the battery has
R
frozen. Thaw the battery out first.
Jump-starting may only be performed from
R
12V batteries.
Only use jump leads which are protected
R
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.
Never start the vehicle using a rapid battery
charger.
