Securing the vehicle on level ground
X On level ground: place chocks or other
suitable items under the front and rear of
the wheel that is diagonally opposite the
wheel you wish to change. Securing the vehicle on slight downhill gradients
X On light downhill gradients: place
chocks or other suitable items in front of
the wheels of the front and rear axle.
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 jack-
ing 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:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the
vehicle is 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 suitable for per-
forming maintenance work under the vehi- cle.
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 positioning wheel chocks. Never
release 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. a rubber mat.
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 tyres and the ground does
not exceed 3 cm.
R never 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.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. Changing a wheel

front wheel arches and just in front of the rear wheel arches (arrows). Covers, front (example: vehicles with AMG equip-
ment)
AMG vehicles and vehicles with AMG
equipment: to protect the vehicle body, the
vehicle has covers fitted next to the jacking
points on the outer sills. X

Removing a wheel !
AMG vehicles:
during removal and repo-
sitioning of the wheel, the wheel rim can
strike the ceramic-brake disc and damage
it. Therefore, take precautions and get a
second person to assist you. Alternatively,
you can use a second centring pin.
! Do not place wheel bolts in sand or dirt.
