have all work involving the battery, e.g.
removing, charging and replacing, carried
out at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.

Risk of accident
If the battery is disconnected:
R the brake boosting effect will not be avail-
able. Greater braking force will then be
required and the brake pedal travel will
be longer. If necessary, depress the
brake pedal with maximum force.
R you can no longer turn the key in the igni-

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
341
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 339).
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 75) 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
i Before towing the vehicle, deactivate tow-
away protection* (Y page 63) and the auto-
matic door locking feature (Y page 132).You could otherwise be locked out when
pushing or towing the vehicle. Fitting the towing eye
Opening the front cover The mountings for the removable towing eyes
are located in the bumpers. They are located
at the front and rear under the covers on the
right-hand side of the vehicle when viewed in
the direction of travel.

343Recovering 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.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck. Towing in the event of the following
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 339).
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 correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, a circuit overload
could cause a fire. Have the cause traced
and rectified at a qualified specialist work-
shop, 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 Practical advice
