Mercedes-Benz 2013 GL Class - Manual (Page 421)

The following must be observed 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
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 is not suited for
performing maintenance work under the
vehicle.
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. Never
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, 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
the maximum clearance between the
underside of the tire and the ground must
be 1.2 in (3 cm).
R
never place your hands and feet under the
raised vehicle.
R
never lie under the raised vehicle.
R
never start the engine when the vehicle is
raised.
R
never open or close a door or the tailgate
when the vehicle is raised.
R
make sure that no persons are present in
the vehicle when the vehicle is raised.
X Using lug wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely.
The jacking points are located just behind the
front wheel housings and just in front of the
rear wheel housings (arrows).
X Take the ratchet wrench out of the vehicle
tool kit and place it on the hexagon nut of
the jack so that the letters
AUF are visible.
