Warning!
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 What to do if …

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. Lamp in center console

Warning!
Batteries contain poisonous and corrosive
substances. Therefore, keep the batteries out
of reach of children.
If a battery is swallowed, seek medical help
immediately. G
Warning!
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/
HazardousWaste/Perchlorate/
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.
i The required replacement batteries are
available at any authorized Mercedes-Benz
Center.
Replacement batteries: Lithium, type
CR 2025 or equivalent.

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. G
Warning!
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. G
Warning!
The bulbs in the tail lamps cannot be replaced
individually. The tail lamp bulbs are under
pressure and could explode during an attempt
to replace them.
If the tail lamps are malfunctioning, have them
replaced at an authorized Mercedes-Benz
Center.
i Since replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.

Notes on bulb replacement
!
Do not replace LEDs or bulbs not
described in this section. You could
otherwise damage the LEDs, the bulbs or
parts of the vehicle. Only have the LEDs and
bulbs replaced at an authorized Mercedes-
Benz Center. G
Observe Safety notes, see page 266.
R Only use 12-volt bulbs of the same type and
with the specified watt rating.
R Switch the lights off before changing a bulb
to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil and
grease.
R If the newly installed bulb does not come
on, contact an authorized Mercedes-Benz
Center.
