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!
Vehicles 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
XVehicles with air suspension program:
Make sure the vehicle level is set to
highway level ( Y page 155).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
switch.
or
XVehicles with KEYLESS-GO: Open the
driver’s door (this puts the starter switch in
position 0, same as with the SmartKey
removed from the starter switch). The
driver’s door can then be closed again.
Open doors only when conditions are safe
to do so.XVehicles with KEYLESS-GO: Remove the
KEYLESS-GO start/stop button from the
starter switch.XHave any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so.
i Vehicles with spare wheel with collapsible
tire or TIREFIT:
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
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

If the tire inflation pressure is at least 20 psi
(1.3 bar), inflate or deflate the tire to the
correct tire inflation pressure (see Tire and
Loading Information placard on the driver’s
door B-pillar):XTo increase tire inflation pressure:
Switch on the electric air pump.XTo decrease tire inflation pressure:

at the end of the filler hose.XDrive to the nearest qualified workshop,
e.g. an authorized Mercedes-Benz Center,
to have the damaged tire replaced.XRecommended duration of use: A
maximum of 300 miles (500 km) at 50 mph

XPrepare the vehicle as described
( Y page 320).XTake the following out of the vehicle:
R spare wheel
R jack
R wheel wrench
R collapsible wheel chockR

R electric air pump (required for vehicles

For information on where to find the
respective items, see “Where will I find ...?”
( Y page 268) and ( Y page 271).
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

164_AKB; 7; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:07:36+02:00 - Seite 324
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 268). For information on setting up
the collapsible wheel chock, see
(Y page 270).
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.

and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery.
If the battery is discharged, the engine can be
started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on all
vehicles. If you cannot access the battery
of the other vehicle, provide jump start
power by an external battery or starter
pack.
R Jump starting should only be performed
when the engine and catalytic converter 32
are cold.
R Do not start the engine if the battery is
frozen. Let the battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump startingwith a more powerful battery could damage
the vehicle’s electrical system. Such
damage will not be covered by the
Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.
