Safety notes
Your vehicle may be equipped with an
MOExtended system or a Minispare wheel.
Vehicles with an MOExtended system do not
have a spare wheel or a TIREFIT kit.
For information on your vehicle’s equipment,
see “Rims and tires” (Y page 365).
GWarning!
The dimensions of the spare wheel are
different from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Contact the nearest authorized Mercedes-
Benz Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than one
spare wheel mounted.
Do not switch off the ESP® when a spare
wheel is mounted.
GWarning!
Your vehicle is equipped with air suspension
program. Do not open or close any doors or
the tailgate while mounting a spare wheel. The
vehicle could rise or lower to a previously
selected level. You or others could be injured
as a result.
Preparing the vehicle
XMake sure the vehicle level is set to
highway level (Y page 159).
XWhenever possible, park the vehicle in a
safe distance from moving traffic on a hard,
flat surface.
XTurn on the hazard warning flasher.XTurn the steering wheel so that the front
wheels are in a straight-ahead position.
XEngage the parking brake.XShift the automatic transmission into park
position P.
XTurn off the engine.XRemove the SmartKey from the starter

iVehicles retrofitted with TIREFIT kit:
Only use the power outlet in the second-
row footwell for electric air pump
operation.
You can use the power outlet even when
the ignition is switched off, e.g. in order to
inflate the collapsible tire.
An emergency shut-off feature is designed
to prevent the vehicle’s on-board voltage
from dropping below a minimum level. If
the on-board voltage drops to this
minimum level, the power outlets are
switched off automatically to help preserve
engine starting power.
Sealing tires with TIREFIT
This section applies to vehicles retrofitted
with a TIREFIT kit only.
Small tire punctures, particularly those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient temperatures
down to -4‡ (-20†).
GWarning!
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely low
tire inflation pressure, or on a flat tire, or a
damaged wheel.
Do not drive the vehicle under such
circumstances.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.
XForeign objects (e.g. screws or nails)
should not be removed from the tire.
XTake the TIREFIT kit, the sticker, and the
electric air pump out of the vehicle.
Two-part sticker
XAttach upper part : of the sticker where
it will be easily seen by the driver on the
instrument cluster.

Lifting the vehicleGWarning!
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 284). For information on setting up
the collapsible wheel chock, see
(Y page 286).
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.
Changing a wheel on a level surface
Changing rear wheel on passenger side (exampleillustration)
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.
Changing a wheel on a slight decline
Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a slight
decline:

Changing wheel on passenger side (exampleillustration)
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.
Changing a wheel on a slight incline
Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a slight
incline:
Changing wheel on passenger side (exampleillustration)
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.
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 286).
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.
