must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehi-
cle:
only use the vehicle-specific jack that has
R
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.
the jack is designed only to raise and hold the
R
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.
avoid changing the wheel on uphill and down-
R
hill slopes.
before raising the vehicle, safeguard it from
R
rolling away by applying the parking brake and
positioning wheel chocks. Do not release 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 tyres and the ground does
not exceed 3 cm.
never place your hands or 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 boot lid
R
when the vehicle is raised.
make sure that no persons are present in the
R
vehicle when the vehicle is raised.
