Jack
GWarning!
Only use the jack supplied with your vehicle
to lift the vehicle briefly for wheel changes. If
you use the jack for any other purpose, you or
others could be injured, as the jack is
designed only for the purpose of changing a
wheel.
When using the jack, observe the safety notes
in the “Mounting the spare wheel” section and
the notes on the jack.

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire.
GWarning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc.

Lamps in instrument cluster
Notes
If any of the following lamps in the instrument
cluster fails to come on during the bulb self-
check when switching on the ignition, have
the respective bulb checked and replaced if
necessary.
When you switch on the ignition, all lamps
(except low-beam headlamp indicator lamp,
high-beam headlamp indicator lamp, and turn
signal indicator lamps unless activated) in the
instrument cluster come on. If a lamp in the
instrument cluster fails to come on when the
ignition is switched on, have it checked and
replaced if necessary.What to do if …297Practical hints164_AKB; 7; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:07:36+02:00 - Seite 297Z
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

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 cargo
compartment (Y page 268).
Two-part sticker
XAttach upper part : of the sticker where
it will be easily seen by the driver on the
instrument cluster.
XAttach lower part ; of the sticker to the
damaged tire (close to the tire valve).
GWarning!
Take care not to allow the contents of TIREFIT
to come in contact with hair, eyes or clothing.
TIREFIT is harmful if inhaled, swallowed or
absorbed through the skin - causes skin, eye
and respiratory irritation.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with TIREFIT,
change clothing as soon as possible.
In case of allergic reaction or rash, consult a
physician immediately.
GWarning!
Keep TIREFIT out of reach of children. If
swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting!
Consult a physician immediately.
iIf sealant has leaked out, let it dry. You
can then peel it off.
If clothing has come in contact with
TIREFIT, have it dry-cleaned with
perchloroethylene as soon as possible.
GWarning!
Observe safety instructions on air pump label.
Your vehicle may be equipped with either of
two versions of the electric air pump:
RVersion 1: The air hose with pressure
gauge and the electrical plug are located
behind a flap.
RVersion 2: The pressure gauge is located
in the pump housing. The air hose and
electrical plug are located at the bottom of
the pump housing.
The following description applies to both
versions. Differences in usage are expressly
declared.
