Observe the following when raising the vehicle:
RWhen raising the vehicle, only use the jack
which Mercedes-Benz has specifically
approved for your vehicle.
RThe vehicle's jack is intended only to raise the
vehicle for a short time when changing a
wheel. It is not suited for performing mainte-
nance work under the vehicle.
RAvoid changing the wheel on uphill and down-
hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Never disengage the
parking brake while the vehicle is raised.
RThe 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.
RMake sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in(3 cm).
RNever place your hands or feet under the
raised vehicle.
RNever lie under the raised vehicle.
RNever start the engine when the vehicle is
raised.
RNever open or close a door when the vehicle
is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
!Only use the jack pump lever middle rod and
the rod with the largest diameter as a lug
wrench extension. Only slide the middle rod
as far as it will go onto the lug wrench. The
rods may otherwise bend and be distorted to
such an extent that they can no longer be
used as a pump lever for the jack.
!Do not place the jack on the leaf spring or
the differential case.
Hydraulic jack
