WARNING
When jacking up the vehicle, only use the jack

Mercedes-Benz for your vehicle.
The
jack is designed exclusively for jacking up
the vehicle at the jacking points built into both
sides of the vehicle. The jack saddle must be 474

Breakdown assistance
placed centrally under the jacking point. The
jack must always be vertical when in use,
especially on inclines or declines.
The
jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizable objects before raising the vehicle with
the jack. Do not disengage the parking brake
while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack. X
Using lug wrench :, loosen the bolts on
the
wheel you wish to change by about one
full turn. Do not unscrew the bolts

The jacking points for the jack are located
behind
the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels (arrows). G
