must be positioned vertically, directly under
the jacking point of the vehicle.
!
The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
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).
Do not 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 trunk lid
R
when the vehicle is raised.
Make sure that no persons are present in the
R
vehicle when the vehicle is raised.
