i Vehicles without spare wheel are not
factory-equipped with the tools required for
a wheel change such as a jack or a wheel
wrench. Some tools required for a wheel
change are specific to your vehicle.
Contact an authorized Mercedes-Benz
Center to obtain the tools approved for
your vehicle. This section describes the
wheel change using the tools approved and
recommended for your vehicle.
Lifting the vehicle
GWarning!
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 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 engage the parking brake firmly and
block the wheels with wheel chocks or other
sizeable 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
to support the jack. 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.XPrevent the vehicle from rolling away by
blocking wheels with wheel chocks or other
sizeable objects.
When your vehicle is equipped with a wheel
chock, it is included with the vehicle tool kit
( Y page 260). For information on setting up
the collapsible wheel chock, see
( Y page 261).
When changing a wheel on a level surface:
XPlace a wheel chock or other sizeable
object in front of and another wheel chock
or other sizeable object behind the wheel
that is diagonally opposite to the wheel
being changed.
Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a hill:
XPlace wheel chocks or other sizeable
objects on the downhill side in front of both
wheels on the side opposite to the side on
which the wheel is to be changed.GWarning!
Only jack up the vehicle on level ground or on
slight inclines/declines. Otherwise, the
vehicle could fall off the jack and injure you or
others.

XOn the wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with wheel
wrench :).
XAssemble the jack (Y page 261).
The jack take-up brackets are located directly
behind the front wheel housings and in front
of the rear wheel housings.
GWarning!
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets. Make
sure the jack arm is fully seated in the jack
take-up bracket.
If you do not position the jack correctly in the
jack take-up bracket, the vehicle can fall off
the jack and seriously or fatally injure you or
others.
! Do not position the jack on the body of
the vehicle, as this may cause damage to
the vehicle.
XAttach reversible ratchet ? to jack = in
such a way that the word UP can be seen.
XPlace jack = on firm ground.XPosition jack = under take-up
bracket ; so that it is always vertical as
seen from the side, even if the vehicle is
parked on an incline.
XTurn ratchet ? up and down until jack =
is fully seated in take-up bracket ; and the
jack base evenly meets the ground.
XJack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the ground.
Removing the wheel
XUnscrew and remove the wheel bolts.
! Do not place wheel bolts in sand or dirt.
This could result in damage to the wheel
bolts and wheel hub threads.
XRemove the wheel.
Attaching the spare wheel
GWarning!

properly attached.
Inflate the collapsible tire using the electric
air pump before lowering the vehicle.
GWarning!
