Risk of injury
Only charge the battery in a well-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions.
This could injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle. You can obtain information about battery
chargers which allow the battery to be
charged while still installed from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre.
G
Risk of injury
There is a risk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process. G
Risk of injury
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
! Never charge the battery when it is instal-
led unless the battery charger has been
tested and approved by Mercedes-Benz.
These battery chargers allow the battery to
be charged while it is still installed.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.

i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R set the time (Y page 104).
On vehicles with COMAND and a naviga-
tion system*, the clock is set automati-
cally.
R reset the sliding/tilting sun-
roof* (Y page 151).
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 73)
R reset the side windows ( Ypage 86). Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R you may only jump-start when the engine
and catalytic converter are cold.
R do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R only use jump leads which have a sufficient
cross-section and insulated terminal
clamps.
i Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Do not use a rapid-charging device to start
the engine. G
Risk of injury
There is a risk of acid burns when jump-start-
ing a vehicle due to the gases which escape
from the battery. Do not lean over the battery
while the engine is being jump-started. G
Risk of explosion
Gases escaping from the battery during jump-
starting may cause minor explosions. Avoid
creating sparks. Keep naked flames away
from the battery, and do not smoke.
Comply with safety precautions and take pro-
tective measures when handling batteries.
You will find these under "Battery" in the
index.

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 power 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. Greater braking force will then be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
force.
Before towing away, make sure that the steer-
ing can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. Towing and tow-starting

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

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. Recovering 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 and tow-starting

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
