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 (
page 226).

222 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
Mercedes-Benz Center.

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot.
Allow 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 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.

Open flap1 on air pump.
Pull out electrical plug4 and air hose
with pressure gauge2.
Screw union nut3 with air hose2 on to
the tire valve.
Insert electrical plug4 into vehicle
cigarette lighter socket.
Turn key in steering lock to position1
(page 29).
PressI on the electric air pump switch.
The electric air pump should now
switch on and inflate the tire.
After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose and the union nut can become hot
during inflation. Please exercise appropri-
ate caution.
If this tire pressure is not attained, turn
off the electric air pump, detach the air
hose from the tire valve, and again
drive vehicle back and forth very slowly
approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Inflate the tire again.
Press0 on the electric air pump
switch.
Turn key in steering lock to position0.
The electric air pump should now be
switched off.
Warning!
G
Observe safety instructions on air pump la-
bel.
!Do not exceed the maximum pressure
of 36 psi (2.5 bar).
!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.

Please exercise appropriate caution.
If this tire pressure is not attained, turn

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 container.
Inflate the tire again.
After attaining a tire pressure of 26 psi
(1.8 bar), press0 on electric air pump
switch8.
The electric air pump should now be
switched off.
Turn key in steering lock to position0
(page 29).
!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.

or call Roadside Assistance.
