Points to remember
G Risk of accident
If you have the vehicle towed, you must use a
rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the voltage supply
or the vehicle's electrical system.
The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. Then, greater braking force will be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
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 cannot
be steered.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle.
It is better to have the vehicle transported
than to have it towed.

stop.
X Insert the wheel wrench handle into the
towing eye and tighten it. Towing the vehicle
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/hm ust
not be exceeded.
For towing distances over 50 km, the entire
vehicle needs to be lifted up and transpor-
ted.
! Vehicles with 4MATIC may not be towed
with the front or rear axle raised.
X Turn the key to position 2(Y page 61) in
the ignition lock.
X Move the selector lever to N. Removing the towing eye

tool kit (Y page 175).
X Insert the wheel wrench handle into the
towing eye and turn it anti-clockwise.
X Unscrew the towing eye.
X Replace the cover and press it until it
engages.
X Return the towing eye and the wheel
wrench to the vehicle tool kit. Transporting the vehicle
The towing eyes or trailer coupling* can be
used to pull the vehicle onto a trailer or trans-
porter if you wish to transport it.
! 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.
X Turn the key to position 2(Y page 61) in
the ignition lock.
X Move the selector lever to N. Fuses
Notes on changing fuses
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart. A Mercedes-
Benz Service Centre will be happy to advise
you. G
Risk of fire
Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the 238 FusesPractical advice
