First, TIREFIT is pumped into the tire. The

pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation

compressor during this phase.

X

Allow the tire inflation compressor to run
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).

!

Do not operate the tire inflation

compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.

If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
(

Y

page 302).

If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(

Y

page 302).

Tire pressure of at least 180 kPa

(1.8 bar/26 psi) is not reached

If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:

X

Press the on/off switch on the tire inflation
compressor to

Unscrew the filler hose from the valve of
the faulty tire.

X

Very slowly drive forwards or reverse
approximately 30 ft (10 m).

X

Pump up the tire again.

WARNING

If after five minutes a pressure of 180 kPa
(1.8 bar/26 psi) cannot be achieved, the tire
is too badly damaged to be repaired reliably
using TIREFIT.
In this case TIREFIT cannot seal the tire
properly.
Do not drive any further.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.

Tire pressure of 180 kPa (1.8 bar/

26 psi) is reached

Unscrew the filler hose from the valve of
the faulty tire.

!

After use, excess TIREFIT may run out of

the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.

X

Stow the tire sealant bottle and the tire
inflation compressor.

X

Pull away immediately.

WARNING

Do not exceed a 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
instrument cluster where it will be easily seen
by the driver.
Vehicle handling characteristics of a TIREFIT
repaired tire may change. Adapt your driving
accordingly.
