General notes The vehicle tool kit can be found in the stowage
well under the luggage compartment floor.
Apart from some country-specific variants, vehi-
cles are not equipped with tyre-changing tools.
Some tools for changing a wheel are specific to the vehicle. For more information on which tools
are required to perform a wheel change on your
vehicle, consult a qualified specialist workshop.
Necessary tyre-changing tools can include, for
example:
R Jack
R Wheel chock
R Wheel wrench
R Ratchet ring spanner
R Centring pin
i The jack weighs approximately 3.4 kg.
The maximum load bearing capacity of the
jack can be found on the adhesive label on the jack.
The jack is maintenance-free. If there is a
malfunction, please contact a qualified spe-
cialist workshop. Vehicles with a TIREFIT kit

Preparing the vehicle
Your vehicle may be equipped with: R MOExtended tyres (tyres with run-flat char-
acteristics)
Vehicle preparation is not necessary on vehi-
cles with MOExtended tyres.

Information on changing and fitting a wheel
(Y page 413).
X Stop the vehicle as far away as possible from
traffic on solid, non-slippery and level ground.
X Switch on the hazard warning lamps.
X Safeguard the vehicle against rolling away
(Y page 191).
X If possible, bring the front wheels into the
straight-ahead position.
X Vehicles with the AIRMATIC package:
make sure that the normal vehicle level is
selected (Y page 222).
X Vehicles with the Off-Road Engineering
package:
make sure that the normal vehicle
level is selected (Y page 216).
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove the
key from the ignition lock.
X Vehicles with KEYLESS-GO: open the driv-
er's door.
The on-board electronics now have status 0.
This is the same as the key having been
removed.
X Vehicles with KEYLESS-GO: remove the
Start/Stop button from the ignition lock
(Y page 158).
X Make sure that the passengers are not endan-
gered as they do so. Make sure that no one is near the danger area while a wheel is being
changed. Anyone who is not directly assisting
in the wheel change should, for example,
stand behind the barrier.
X Get out of the vehicle. Pay attention to traffic
conditions when doing so.
X Close the driver's door.
X Place the warning triangle at a suitable dis-
tance (Y page 386). Observe legal require-
ments.
X Unload heavy luggage.
i Only operate the tyre inflation compressor
using a 12 V socket, even if the ignition is
turned off (Y page 364).
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the on-
board voltage is too low, the power to the
sockets is automatically cut. This ensures
that there is sufficient power to start the
engine. MOExtended tyres (tyres with run-flat
characteristics)
General notes With MOExtended tyres (tyres with run-flat char-
acteristics), you can continue to drive your vehi-
cle even if there is a total loss of pressure in one or more tyres. The affected tyre must not show
any clearly visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the tyre
wall. You will find this marking next to the tyre
size designation, the load-bearing capacity and
the speed index.
MOExtended tyres may only be used in conjunc- tion with an activated tyre pressure loss warning
system or tyre pressure monitor.
If a pressure loss warning message appears in the multifunction display:
R observe the instructions in the display mes-
sages (Y page 330)
R check the tyre for damage
R if driving on, observe the following notes
The driving distance possible in run-flat mode is approximately 80 km when the vehicle is parti-
ally laden and approximately 30 km when the
vehicle is fully laden. 388

The folding wheel chock is an additional secur-
ing measure to safeguard the vehicle from roll-
ing away, for example when changing a wheel.
X Fold both plates upwards :.
X Fold out lower plate ;.
X Insert the lugs on the lower plate fully into the
openings in base plate =.X
Place chocks or other suitable items under
the front and rear of the wheel that is diago-
nally opposite the wheel you wish to change.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi- cle:
R only use the vehicle-specific jack that has
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake and positioning wheel chocks. Do not release the
parking brake while the vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R do not place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the tailgate
while the vehicle is raised.
R make sure that no persons are present in the
vehicle when the vehicle is raised. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts completely. Changing a wheel
