Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described
(
page 519).
Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(
page 490).
Take the Minispare wheel out of the
cargo compartment (
page 495).Lifting the vehicle
!Depending on vehicle production date your
vehicle may be equipped with a scissors-type
jack (located under the cargo compartment
floor). If so equipped, only use this jack when
jacking up the vehicle as otherwise the vehicle’s
underbody can be damaged. See separate
instructions for scissors-type jack.
Warning!G
When jacking up the vehicle, only use the
jack which has been specifically approved
by Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. Make
sure the jack arm is fully seated in the jack
take-up bracket.
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 in-
jury, use the jack only to lift the vehicle dur-
ing a wheel change.
Never get beneath the vehicle while it is sup-
ported 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 set parking brake and block
wheels with wheel chocks or other sizeable
objects before raising vehicle with jack. Do
not disengage parking brake while the vehi-
cle is raised.
Make sure that the ground on which the ve-
hicle is standing and where you place the
jack is solid, level and not slippery. If neces-
sary, use a large underlay. On slippery sur-
faces, such as tiled floors, you should use a
non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing ca-
pacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
