Observe the following points when towing
with a tow rope:
R secure the tow rope on the same side on
both vehicles.
R make sure that the tow rope is not longer
than legally permitted. Mark the tow rope
in the middle, e.g. with a white cloth
(30 x 30 cm). This makes other road
users aware that a vehicle is being
towed.
R only secure the tow rope to the towing
eye.
R observe the brake lamps of the towing
vehicle while driving. Always maintain a
distance so that the tow rope does not
sag.
R do not use steel cables or chains to tow
your vehicle. You could otherwise dam-
age the vehicle.
! Do not use the towing eyes for recovery
purposes as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high,
the vehicles could be damaged.
! Shift the automatic transmission to
Nand
do not open the driver's or front passeng-
er's door during towing. The automatic
transmission may otherwise shift to posi-
tion P, which could damage the transmis-
sion.
! You may tow the vehicle for a maximum of
50km. 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.
Observe the legal requirements for the rele-
vant countries when towing.
It is better to have the vehicle transported
than to have it towed.
If the vehicle has suffered transmission dam-
age, have it transported on a transporter or
trailer. The automatic transmission must be in posi-
tion
Nwhen the vehicle is being towed away.
If the automatic transmission cannot be shif- ted to position N, have the vehicle transpor-
ted on a transporter or trailer.
The battery must be connected and charged. Otherwise, you:
R cannot turn the key in the ignition lock to
position 2
R cannot release the electric parking brake
R cannot shift the automatic transmission to
position N
i Deactivate the automatic locking feature
before the vehicle is towed away
(Y page 92). You could otherwise be locked
out when pushing or towing the vehicle.
i Deactivate tow-away protection before
the vehicle is towed away (Y page 81). Fitting/removing the towing eye

the ground
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 369).
The automatic transmission automatically
shifts to position Pwhen you open the driver's
or front-passenger door or when you remove the key from the ignition lock.
In order to ensure that the automatic trans-
mission stays in position Nwhen towing the
vehicle, you must observe the following
points:
X You must use the key instead of the Start/
Stop button (Y page 161).
X Make sure that the vehicle is stationary and
that the key is in position 0in the ignition
lock.
X Turn the key to position 2in the ignition
lock.
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the electric parking brake. X
Leave the key in position 2in the ignition
lock.
X Switch on the hazard warning lamps
(Y page 128).
i In order to signal a change of direction
when towing the vehicle with the hazard
warning lamps switched on, use the com-
bination switch as usual. In this case, only
the turn signals for the desired direction
flash. When you reset the combination
switch, the hazard warning lamps start
flashing again. Towing the vehicle away with the rear
axle raised
Only vehicles without 4MATIC can be
towed away with the rear axle raised.
! The ignition must be switched off if you
are towing the vehicle with the rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged.
! Vehicles with automatic transmission
must not be towed with the rear axle raised.
The car/trailer combination may otherwise swerve or even overturn. Transporting the vehicle
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise,
the vehicle could be damaged.
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporta-
tion.

As soon as the vehicle is loaded:
X Prevent the vehicle from rolling away by
applying the electric parking brake.
X Shift the automatic transmission to posi-

X Secure the vehicle. Notes for 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise,
the transmission may be damaged.
Vehicles with 4MATIC may either be towed
away with both axles on the ground or be loa- ded up and transported.
If the vehicle has transmission damage or
damage to the front or rear axle, have it trans-
ported on a transporter or trailer.
In the event of damage to the electrical
system: if the battery is defective, the auto-
matic transmission will be locked in position

tion N, you must provide power to the vehi-
cle's electrical system in the same way as
when jump-starting (Y page 366).

Important safety notes
G
WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
The fuse allocation chart is on the fuse box in
the boot (Y page 374).
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz Ser-
vice 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 in your vehicle disconnect faulty
circuits. If a fuse blows, all the components on the circuit and their functions will fail. Before replacing a fuse
X Safeguard the vehicle against rolling away
(Y page 181).
X Switch off all electrical consumers.
X Make sure that the ignition is switched off
(Y page 161).
