Foreign objects (e.g. screws or nails)

Warning!
G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approx. 0.16 in (4 mm) and tire dam-
age caused by driving with extremely low
tire inflation pressure, or on a flat tire, or a
damaged wheel.
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance.
Warning!
G
Take care not to allow the contents of
T I R E F I T t o c o m e i n c o n t a c t w i t h h a i r , e y e s o r
clothing. TIREFIT is harmful if inhaled, swal-
lowed or absorbed through the skin - causes
skin, eye and respiratory irritation.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with TIREFIT,
change clothing as soon as possible.
In case of allergic reaction or rash, consult a
physician immediately.Warning!
G
Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting!
Consult a physician immediately.
Keep away from open flame or heat source.
iIf sealant has leaked out, let it dry. You
can then peel it off.

Screw filler hosea onto tire valve7.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn the SmartKey in the starter switch
to position1 (
page 36).
or

Press the KEYLESS-GO* start/stop
button (
page 37) on the gear selec-
tor lever 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 5 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 inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 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 hose5onto tire valve7.

Inflate the tire again.
Warning!
G
Observe safety instructions on air pump la-
bel.
!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.


391 Practical hints
Flat tire

After attaining a tire inflation pressure
of 26 psi (1.8 bar), press 0 on electric
air pump switch8.
The electric air pump should now be
switched off.

Turn the SmartKey in the ignition to
position0 (
page 36).
or

Press the KEYLESS-GO* start/stop
button (
page 37) on the gear selec-
tor lever twice. Do not depress brake
pedal.

Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.

Store the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.

Close the trunk lid.

Drive away immediately.
The TIREFIT sealant will distribute itself
evenly inside the tire.
Warning!
G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, 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.
Warning!
G
Do not exceed vehicle speed of
50 mph (80 km / h). A TIREFIT repair is not
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.


392 Practical hintsFlat tire
After driving vehicle for an initial
10 minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.

Visit an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.

Bring used TIREFIT materials to an au-
thorized Mercedes-Benz Center for
proper disposal.

Replace your TIREFIT container every
four years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!
G
If tire inflation pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct pres-
sure (see placard on the driver’s door
B-pillar), and drive vehicle to nearest tire re-
pair facility to have tire repaired or replaced.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km/h)
with the recommended tire inflation pres-
sure.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
Do not exceed vehicle speed of 50 mph
(80 km/h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
