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

Towing in the event of malfunctions
In the event of damage to the transfer
case Have the propeller shafts between the axles
and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the front axle
Have the propeller shaft between the rear
axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the rear axle Have the propeller shaft between the front
axle and the transfer case removed.
Have the vehicle towed with the rear axle
raised.
! New bolts must always be used when the
propeller shafts are refitted. The specified
tightening torques must be observed.
i Consult a Mercedes-Benz Service Centre.
In the event of damage to the electrical
system If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to neutral,
you must supply power to the vehicle’s elec-
trical system in the same way as jump-start-
ing (Y page 276).
Have the vehicle transported on a transporter
or trailer. 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
required fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. A circuit overload could other-
wise cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses are located in various fuse boxes:
R dashboard fuse box on the front-passenger
side
R fuse box in the engine compartment on the
right-hand side of the vehicle
R fuse box in the luggage compartment on
the right-hand side of the vehicle
Fuse allocation chart The fuse allocation chart is located with the
vehicle tool kit (Y
page 209) in the stowage
compartment under the luggage compart-
ment floor. 280
