It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Do not use the towing eye for recovery,
as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
For towing distances over 50 km, the entire
vehicle must be lifted up and transported.
! On vehicles with KEYLESS GO*, use the
key instead of the Start/Stop button. Turn
the key to position 2in the ignition lock and
shift the automatic transmission to N. Then
turn the key back to 0and leave it in the
ignition lock.
! Only secure the tow cable or towing bar
to the towing eyes. You could otherwise
damage the vehicle.
R Tow-starting the vehicle is not permitted.
R The vehicle may not be towed with the front
or rear axle raised.
R If the vehicle has suffered transmission
damage, have it carried away on a trans-
porter or trailer.
R If the engine does not start, try jump-start-
ing it (Y page 276).
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-Benz
Service Centre.
R If you are towing the vehicle, move the
automatic transmission selector lever to N
and turn the key to position
2 (Y page 63) in the ignition lock.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
- you cannot switch on the ignition.
- you cannot shift the transmission to posi-
tion N.
- you have no support when braking.
i Switch off the automatic locking feature
before the vehicle is towed (Y page 107).
Otherwise, you could be locked out when
pushing or towing the vehicle.
Deactivate tow-away protection*
(Y page 55) before the vehicle is towed. Fitting the towing eye
Vehicles with a trailer tow hitch*: if you
intend to use the vehicle for towing, fit the ball
coupling and connect the towbar to this.
Opening the covers The mountings for the removable towing eyes
are located in the bumpers. They are located
at the front and rear behind covers. 278

! Only secure the vehicle by the wheels or
wheel rims, not by parts of the vehicle such
as axle or steering components. Otherwise,
the vehicle could be damaged. Recovering a vehicle that has become
stuck
Take great care when recovering a vehicle
whose drive wheels have become embedded
in loose earth or mud, particularly if the vehi-
cle is laden.
When recovering the vehicle do not use jerky
movements and do not pull it at an angle. The
chassis could otherwise be damaged.
Never attempt to recover a vehicle with a
trailer attached.
