Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually.
X Bring the front wheels into the straight-ahead
position.
X Shift the transmission to position 005D.
X Switch off the engine.
X With KEYLESS-GO start function or vehi-
cles with KEYLESS-GO:

door.
The vehicle electronics are now in key posi-
tion 0092. This is the same as the SmartKey
having been removed.
or X Remove the SmartKey from the ignition lock.
X If included in the vehicle equipment, remove
the tire-change tool kit from the vehicle.
X Safeguard the vehicle against rolling away.
Securing the vehicle to prevent it from
rolling away If your vehicle is equipped with a wheel chock, it
can be found in the tire-change tool kit
(Y page 249). The folding wheel chock is an additional safety
measure to prevent the vehicle from rolling
away, for example when changing a wheel.
X Fold both plates up 0043.
X Fold out lower plate 0044.
X Guide the lugs on the lower plate fully into the
openings in base plate 0087. 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.
! Only position the jack at the appropriate
jacking point of the vehicle. Otherwise, you
could damage the vehicle.
Observe the following when raising the vehi- cle:
R To raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
R The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
R Avoid changing the wheel on uphill and down-
hill slopes. 282

R
Before raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage 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 tires and the ground does not
exceed 1.2 in (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 trunk lid
when the vehicle is raised.
R Make sure that no persons are present in the
vehicle when the vehicle is raised.
Vehicles with hub caps: the hub cap covers
the wheel bolts. Before you can unscrew the
wheel bolts, you must remove the hub cap. X
To remove: take socket0044and lug wrench
0087 from the vehicle tool kit (Y page 249).
X Position socket 0044on hub cap 0043.
X Position lug wrench 0087on socket 0044.
X Using lug wrench 0087, turn hub cap0043coun-
ter-clockwise and remove it.
X To install: before installing, check hub cap 0043
and the wheel area for soiling and clean if
necessary.
X Put hub cap 0043in position and turn until it is in
the right position. X
Position socket 0044on hub cap 0043.
X Attach lug wrench 0087to socket 0044and
tighten hub cap 0043.
The tightening torque must be
18 lb-ft (25 Nm).
i Note
that the hub cap should be tightened
to the specified torque of 18 lb-ft (25 Nm).
Mercedes-Benz recommends that you have
the hub cap installed at a qualified specialist
workshop. X
Using lug wrench 0087, loosen the bolts on the
wheel you wish to change by about one full
turn. Do not unscrew the bolts completely. The jacking point is centered between the front
and rear wheel arches (arrow). Changing a wheel
