Points to remember
G
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 malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
The electric power steering and the brake
force booster do not work when the engine
is not running. Greater braking force will
then be required and the brake pedal travel
will be longer. If necessary, depress the
brake pedal with maximum force.
Do not tow the vehicle if the key cannot be
turned in the ignition lock. If this is the case,
the steering is locked and the vehicle can-
not be steered.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
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 with-
out jerking. If the tractive power is too high,
the vehicles could be damaged.
! Do not use the towing eye for recovery,
as this will 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.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! On vehicles with KEYLESS GO*: use the
key instead of the KEYLESS GO * button.
Turn the key to position 2in the ignition
lock and set 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 may otherwise
damage the vehicle. Practical advice

Towing and tow-starting
331
R
Tow-starting the vehicle is not permitted.
R Vehicles with 4MATIC *must not be towed
with the front or rear axle raised.
R If the engine does not start, try jump-start-
ing it (Y page 329).
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 the vehicle has suffered transmission
damage, have it carried away on a trans-
porter or trailer.
R If you are towing the vehicle, move the
automatic transmission selector lever to
N and turn the key to position 2
(Y page 76) 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 move the selector lever to N
- you have no support when braking

away protection* (Y page 64)and the auto-
matic door locking feature (Y page 134).You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
