Observe legal requirements. Changing a wheel and fitting the spare
wheel G
Risk of accident
If the spare wheel is more than six years
old, or it does not correspond to the regular
wheel type: have the spare wheel replaced
by a new wheel at the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Never drive the vehicle with more than one
spare wheel fitted.
Vehicles with different tyre dimensions on
the front and rear axles: wheel and tyre size
of the spare wheel and normal wheel are
different. When using the spare wheel, the
handling characteristics are compromised.
Do not exceed the maximum speed of 80
km/h. G
Risk of accident
Vehicles with AMG equipment: when you fit
the spare wheel, make sure you observe the
following:
R the maximum speed of 80 km/h
R the prescribed tyre pressure
Preparing the vehicle X
Prepare the vehicle as described
(Y page 243).
X If a trailer is coupled, uncouple it.
X Remove the vehicle tool kit and the jack
(Y page 191).
X Remove the spare wheel from the spare
wheel bracket (Y page 192).
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under the front and rear of the wheel
that is diagonally opposite the wheel you
wish to change.
X On downhill gradients: place chocks or
similar items under both wheels of the
other axle. Raising
the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise
the vehicle as described, it could slip off the
jack (e.g. when starting the engine, opening
or closing a door or the tailgate) and you
could be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may: Practical advice

Thus, it is important to make sure that the
jack is positioned correctly in the respec-
tive jacking points. Before positioning the
jack, remove any dirt that may have collec-
ted in the jacking points. Wheel wrench

By using the wheel wrench, loosen the
wheel bolts on the wheel you wish to
change by about one full turn. Do not
unscrew the bolts completely. Pump lever

i Never turn pressure release screw 2by
more than one to two revolutions. Other-
wise, hydraulic fluid could escape. X
Position the jack at the front and rear axle
carrier tubes The jack must always stand
vertically, even on slopes.
X Raise the vehicle by pumping (arrow) until
the tyre is three centimetres off the ground
at the most.

!
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

Towing and tow-starting
254
Towing eye, rear The rear towing eye is located under the
bumper, on the left-hand side when viewed in
the direction of travel. 1
Towing eye Towing the vehicle
! 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. X
Turn the key to position 2in the ignition
lock.
X Shift the transfer case to neutral position
N (Y page 92).
X Move the selector lever to N.
i The transmission can only change gear
when the battery has sufficient charge.
If you cannot move the selector lever to
N, you must remove the propellor shafts to
the driven axles. Transporting the vehicle
The towing eyes can be used to pull the vehi-
cle onto a trailer or transporter for transport-
ing purposes.
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components. The
vehicle could otherwise be damaged.
X Turn the key to position 2in the ignition
lock.
X Move the selector lever to N.
X Shift the transfer case to neutral position
N (Y page 92). 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 in the event of malfunctions
Engine damage, gear damage or electri-
cal faults X
Move the selector lever to N(Y page 90).
X Change gear into neutral N(Y page 92).
In the event of damage to the transfer
case Have the propeller shafts between the axles
and the transfer case removed.Practical advice
