R Jump-starting must only be performed
when the engine and catalytic converte r
are cold.
R Do not start the engine if the battery ha s
frozen. Thaw the battery out first.
R Jump-starting may only be performed from
12V batteries .
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 informatio n
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. G

starting a vehicle due to the gases which
escape from the battery. Do not lean over

started. G
Risk of explosion

Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunctio n
R the voltage supply or the vehicle's elec-
trical system is damage d
There is no power assistance for the steer-
ing when the engine is not running.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirement s
in all countries concerned.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
