Raising the vehicle
G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the
jack must be positioned vertically, directly
under the jacking point of the vehicle.
The following must be observed 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
incorrectly, the jack could tip over with the
vehicle 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
performing maintenance work under the
vehicle.
avoid changing the wheel on uphill and
R
downhill slopes.
before raising the vehicle, secure it from
R
rolling away by applying the electric
parking brake and positioning wheel
chocks. Never release the electric 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, 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.
