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. G
WARNING
On uphill and downhill slopes, the jack could
tip over with the vehicle raised. There is a risk
of injury.
Do not change wheels on uphill or downhill
gradients. Notify a qualified specialist work-
shop.
! Only position the jack on the jacking
points intended for this purpose. You could
otherwise damage the vehicle.
Observe the following when raising the vehi-
cle:
R When raising the vehicle, only use the jack
which Mercedes-Benz has specifically
approved for your vehicle.
R The vehicle's jack is intended only to raise
the vehicle for a short time when changing
a wheel. 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 disen-
gage 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 Make sure that the distance between the
underside of the tires and the ground does
not exceed 1,2 in(3 cm).
R Never place your hands or 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 when the vehi-
cle is raised.
R Make sure that no persons are present in
the vehicle when the vehicle is raised. Changing wheels
