Replacing bulbs
Replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment.

360 Practical hintsReplacing bulbsRear lamps Notes on bulb replacement
Use only 12 volt bulbs of the same type
and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Center.
Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon* lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.

368 Practical hintsFlat tire
Unscrew the valve cap from tire
valve7.
Screw filler hosea onto tire valve7.
Insert electrical plug4 into vehicle
cigarette lighter socket.
Turn SmartKey in starter switch to
position1 (
page 31).
or
Press the KEYLESS-GO* start / stop
button (
page 33) on the selector le-
ver once. Do not depress brake pedal.
Press I on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After five minutes, the pressure gauge
must display at least 26 psi (1.8 bar). The
air hose can become hot during inflation.
Please exercise appropriate caution.
If this tire pressure is not attained, turn
off the electric air pump, detach the fill-
er hose from the tire valve, and drive
vehicle back and forth very slowly ap-
proximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Unscrew the air pump’s air hose5
from flange6 of the TIREFIT contain-
er.
Screw air hose5 onto tire valve7.
Inflate the tire again.
After attaining a tire pressure of 26 psi
(1.8 bar), press 0 on electric air pump
switch8.
The electric air pump should now be
switched off.
iIf sealant has leaked out, let it dry. You
can then peel it off.
!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
If a tire pressure of 26 psi (1.8 bar) is not at-
tained, tire is too severely damaged for
TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
