the reference value.XCarefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers.XCheck and adjust tire inflation pressure as required.XIf necessary, change the wheel ( Y page 405).GWarning!
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.

GWarning!
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with the engine oil temperature above 140†. Doing
so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.

GWarning!
Each tire, including the spare (if provided), should be checked at least once a month when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on the Tire and
Loading Information placard on the driver’s door B-pillar or the tire inflation pressure label on the
inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on
the Tire and Loading Information placard or the tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are
significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver’s responsibility to maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the telltale will flash for approximately
1 minute and then remain continuously illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

Replacing bulbs
Safety notes
Safe vehicle operation depends on proper
exterior lighting and signaling to a large
degree.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment.
GWarning!
Bulbs and bulb sockets can be very hot. Allow
the lamp to cool down before changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
i Since replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.
i If the headlamps are fogged up on the
inside as a result of high humidity, driving
the vehicle a distance with the lights on
should clear up the fogging.
Replacing bulbs for front lamps
You cannot replace the bulbs in the front
lamps yourself. Contact an authorized
Mercedes-Benz Center or a qualified
workshop.
Replacing bulbs for rear lamps
Except for the license plate lamp bulbs, you
cannot replace the bulbs in the rear lamps
yourself.
License plate lamps
A bulb of type C 5 W is required.

Safety notes
GWarning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(KEYLESS-GO: Make sure the vehicle’s on-
board electronics have status 0) before
replacing a wiper blade. Otherwise, the wiper
motor could suddenly turn on and cause
injury.

wheels are in a straight-ahead position.
XEngage the electronic parking brake.XShift the transmission into park position P.XTurn off the engine.XKEYLESS-GO: Open the driver’s door (this
puts the starter switch in position 0, same

be closed again. Open doors only when
conditions are safe to do so.
or
XRemove the SmartKey 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.
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 -40‡ (-40†).
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 trunk
(Y page 362).
XOpen the TIREFIT kit.XAttach upper part of sticker D where it will
be easily seen by the driver on the
instrument cluster.
XAttach lower part of sticker D 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.
