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.
! When towing, pull away slowly and with-
out jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! 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
entire vehicle needs to be lifted up and
transported. !
Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission*
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 233).
R If it is not possible to jump-start the vehicle ,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Ben z
Service Centre.
R If the vehicle has suffered transmission
damage, it must only be towed with the rear
axle raised.
R The selector lever must be in position Non
vehicles with automatic transmission*.
R If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
