Do not place wheel bolts in sand or on a
dirty surface. This could cause damage to
the bolt and wheel hub threads.
X Remove the wheel.
Fit ting a new wheel G
Risk of accident
Replace damaged or corroded wheel bolts.
Never oil or grease wheel bolts. G
Risk of accident
If a wheel hub thread is damaged, you must
not drive the vehicle any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre or Service
24h for this purpose. In particular, work rel-
evant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop. G
Risk of accident
Only use wheel bolts that have been
designed for the wheel and the vehicle. For
safety reasons, Mercedes-Benz recom- mends that you only use wheel bolts which
have been approved for Mercedes-Benz
vehicles. Other bolts could work loose.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehi-
cle could topple off the jack.
X Clean the wheel and wheel hub contact
surfaces.
X Place the wheel on the wheel hub and push
it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
Lowering the vehicle X
Open the pressure release screw on the
jack using the pump lever (Y page 244) by
approximatel y one turn.
X Place the jack to one side. 1
–5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (1 to5). The tightening torque is
130 Nm . G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a torque of 130 Nm.
X Push the jack piston back in and close the
drain plug.
X Secure the faulty wheel by using the fas-
tening bolts to the exterior spare wheel
bracket. Practical advice

Jump-starting
251
X
Connect positive terminal clamp 1and
secure the cover.
X Connect negative terminal clamp 3.
X Connect breather hose 4. Make sure that
a cell cap is fitted between battery 2and
breather hose 4.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:2
R set the time (Y page 106)
R reset the head restraints on the front
seats (Y page 61)
R reset the side windows ( Ypage 85) 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 Jump-starting may only be performed 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 with
batteries that have the same nominal volt-
age.
R Only use jump leads which are protected
against polarity reversal and which have a
sufficient cross-section and insulated ter-
minal clamps.
i Jump leads which are protected against
polarity reversal and further information
about jump-starting can be obtained from
any Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts. Only use the jump-starting pro-
cedure for the battery in the engine com-
partment. Do not use a rapid-charging device to start
the engine. G
Risk of injury
There is a risk of acid burns when jump-
starting 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
protective measures when handling batter-
ies. You will find these under "Battery" in
the index.
X Make sure that the two vehicles do not
touch.
X Apply the parking brake.
X Move the selector lever to P.
X Switch off all electrical consumers. Practical advice

Towing and tow-starting
253
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.
! 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.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the transfer case can be shifted into neu-
tral N, you can tow the vehicle.
R If the transfer case cannot be shifted into
neutral N, you can tow the vehicle with one
axle raised. Please bear the following in
mind: -
remove the propeller shaft between the
transfer case and the rolling axle.
- turn the key to position 1in the ignition
lock.
R If the engine does not start, try jump start-
ing (Y page 251).
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 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
i Switch off the automatic locking feature
before the vehicle is towed (Y page 108).
You could otherwise be locked out when
pushing or towing the vehicle. Towing eye
Towing eye, front The vehicle is equipped with two towing eyes.
These are located at the front, under the
bumper.
