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 coolant temperature above 248‡
(120†). Doing so may cause serious
damage which is not covered by the

After the malfunction has been remedied, the combination low tire

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.What to do if …265Practical hints230_AKB; 6; 22, en-USd2ureepe,Version: 2.11.8.12009-07-28T18:49:58+02:00 - Seite 265Z

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 thenremain 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.

GWarning!
Batteries contain poisonous and corrosive
substances. Therefore, keep the batteries out
of reach of children.
If a battery is swallowed, seek medical help
immediately.
GWarning!
SmartKey batteries contain perchlorate
material, which may require special handling
and regard for the environment. Check with
your local government’s disposal guidelines.
California residents, see www.dtsc.ca.gov/

index.cfm.
Batteries contain materials that can harm the
environment if disposed of improperly.
Recycling of batteries is the preferred method
of disposal. Many states (USA only) or
provinces (Canada only) require sellers of
batteries to accept old batteries for recycling.
When inserting the batteries, make sure they
are clean and free of lint.
When replacing batteries, always replace
both batteries.
iThe required replacement batteries are
available at any authorized Mercedes-Benz
Center.

Replacing bulbs for front lamps
GWarning!
Do not remove the cover for the Bi-Xenon
headlamp. Because of high voltage in Xenon
lamps, it is dangerous to replace the bulb or
repair the lamp and its components. It is
recommended to have such work done by a
qualified technician.
Before you start to replace a bulb for a front
lamp, do the following:

Replacing wiper blades
Safety notes
GWarning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(vehicles with 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.
GWarning!
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! To avoid damage to the hood, the wiper
arms should only be folded forward when
in the vertical position.
! Never open the hood when a wiper arm is
folded forward.
Hold on to the wiper when folding a wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
Do not allow a wiper arm to contact the
windshield glass without a wiper blade
inserted.
Mercedes-Benz recommends that you have
this work carried out at an authorized
Mercedes-Benz Center.
