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.

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.

switch.
Turn key in steering lock to position0.
The electric air pump should now be
switched off.
Warning!

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.
