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.
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.

Make sure that no persons are present in the
vehicle when the vehicle is raised.
