Changing a wheel and mounting the
spare wheel
Preparing the vehicle
GWarning!
The wheel and tire size of the emergency
spare wheel/spare wheel may differ to that of
the damaged wheel. When using an
emergency spare wheel/spare wheel the
handling characteristics of the vehicle may
change.
Adapt your style of driving accordingly.
Never operate the vehicle with more than one
emergency spare wheel/spare wheel that
differs in size.
Only use an emergency spare wheel/spare
wheel of a differing size briefly and do not
switch off ESP®.
When using an emergency spare wheel, you
must not exceed a maximum speed of 50 mph
(80 km/h).
GWarning!
Have the emergency spare wheel/spare
wheel replaced with a new wheel as soon as
possible at a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.
iVehicles without an emergency spare
wheel/spare wheel are not equipped with
wheel-changing tools at the factory. For
more information on which tools are
required to perform a wheel change on your
vehicle, e.g. wheel chock, alignment bolt or
lug wrench, consult an authorized

Raising 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 jacking points built into both
sides of the vehicle. The jack saddle must be
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.
XUsing lug wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely.
