GWARNING
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.
!Only position the jack at the appropriatejacking point of the vehicle. Otherwise, youcould damage the vehicle.
Observe the following when raising the vehi-cle:
RTo raise the vehicle, only use the vehicle-specific jack that has been tested andapproved by Mercedes-Benz. If used incor-rectly, the jack could tip over with the vehi-cle raised.
RThe jack is designed only to raise and holdthe vehicle for a short time while a wheelis being changed. It must not be used forperforming maintenance work under thevehicle.
RAvoid changing the wheel on uphill anddownhill slopes.
RBefore raising the vehicle, secure it fromrolling away by applying the parking brakeand inserting wheel chocks. Do not disen-gage the parking brake while the vehicle israised.
RThe jack must be placed on a firm, flat andnon-slip surface. On a loose surface, a large,flat, load-bearing underlay must be used. Ona slippery surface, a non-slip underlay mustbe used, e.g. rubber mats.
RDo not use wooden blocks or similar objectsas a jack underlay. Otherwise, the jack willnot be able to achieve its load-bearing capa-city due to the restricted height.
RMake sure that the distance between theunderside of the tires and the ground doesnot exceed 1.2 in (3 cm).
RNever place your hands and feet under theraised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle israised.
RDo not open or close a door or the trunk lidwhen the vehicle is raised.
RMake sure that no persons are present inthe vehicle when the vehicle is raised.
