Changing a wheel
288
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:
To raise the vehicle, only use the vehicle-spe-
R
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
The jack is designed only to raise and hold the
R
vehicle for a short time while a wheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
Avoid changing the wheel on uphill and down-
R
hill slopes.
Before raising the vehicle, secure it from roll-
R
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
The jack must be placed on a firm, flat and
R
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.
Do not use wooden blocks or similar objects
R
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
Make sure that the distance between the
R
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
Never place your hands and feet under the
R
raised vehicle.
Do not lie under the vehicle.
R
Do not start the engine when the vehicle is
R
raised.
Never open or close a door or the tailgate
R
when the vehicle is raised.
Make sure that no persons are present in the
R
vehicle when the vehicle is raised.
Using lug wrench :, loosen the bolts on the
X
wheel you wish to change by about one full
turn. Do not unscrew the bolts completely.
Jacking points
The jacking points are located just behind the
front wheel housings and just in front of the rear
wheel housings (arrows).

X
