WARNING
Fuels are toxic and harmful to health. There is a risk of injury.
You must avoid fuels coming into contact with
skin, eyes and clothes or being swallowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process.
If you or others come into contact with fuel,
observe the following points:
R Immediately rinse the fuel off your skin with
soap and water.
R If you get fuel into your eyes, immediately
rinse your eyes throughly with clean water.
Seek medical attention immediately.
R Seek medical attention immediately if fuel
has been swallowed. Do not induce vomit-
ing.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
Electrostatic charging can lead to the creation
of sparks and ignite fuel vapor. There is a risk of fire and explosion.
Touch the metallic body of the vehicle before
you open the fuel filler cap or handle the pump nozzle. Any possible electrostatic charge
present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Overfilling the fuel tank could damage the
fuel system. !
Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.

X Completely insert the filler neck of the fuel
pump nozzle into the tank, hook in place and refuel.
X Only fill the tank until the pump nozzle
switches off. Do not add any more fuel after the pump stops
filling for the first time. Otherwise, fuel may leak
out.

Tire pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five minutes:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the filler hose.
X Very slowly drive forwards or reverse approx-
imately 30 ft (10 m).
X Pump up the tire again.
After a maximum of five minutes the tire pres-
sure must be at least 180 kPa (1.8 bar/
26 psi). G
WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached G
WARNING
A tire temporarily sealed with tire sealant
impairs the vehicle's driving characteristics
and is not suitable for driving at higher
speeds. There is a risk of an accident.
Adapt your driving style accordingly and drive carefully. Do not exceed the maximum per-
missible speed for a tire sealed with tire seal- ant.
The maximum permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h).
The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driver's
field of vision.
! Residue from the tire sealant may come out
of the filler hose after use. This could cause
stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit. H
Environmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 180 kPa (1.8 ba r/26 psi) has
been attained after five minutes:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of the
faulty tire.
X Stow the tire sealant bottle and the tire infla-
tion compressor.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tire pressure with the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
i In cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCedes (in the
USA) or 1-800-387-0100 (in Canada).
X Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the Tire and
Loading Information placard on the driver's
side B-pillar or the tire pressure table in the
fuel filler flap for values.
X To increase the tire pressure: switch on the
tire inflation compressor. Flat tire
