Observe the following when raising the
vehicle:
R
To raise the vehicle, only use the vehicle-
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.
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 suited for per-
forming maintenance work under the vehi-
cle.
R
Avoid changing the wheel on uphill and
downhill slopes.
R
Before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Do not disen-
gage 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
Never place your hands and 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.
