Changing a wheel
328
must be positioned vertically, directly under
the jacking point of the vehicle.
! The jack is designed exclusively for jack-
ing up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged.
Observe the following when raising the
vehicle:
To raise the vehicle, only use the vehicle-
R
specific jack that has been tested and
approved by Mercedes-Benz. If used incor-
rectly, the jack could tip over with the vehi-
cle raised.
The jack is designed only to raise and hold
R
the vehicle for a short time while a wheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
Avoid changing the wheel on uphill and
R
downhill slopes.
Before raising the vehicle, secure it from
R
rolling away by applying the parking brake
and inserting wheel chocks. Do not disen-
gage 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
R
objects 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.
Do not open or close a door or the trunk lid
R
when the vehicle is raised.
Make sure that no persons are present in
R
the vehicle when the vehicle is raised.
Vehicles with alloy wheels and hub caps:
the wheel bolts are covered by a hub cap.

iants can be installed.
