Flat tire
̈ After attaining a tire inflation pressure
of 26 psi (1.8 bar), press 0 on electric
air pump switch 8.
The electric air pump should now be
switched off.
̈ Turn the SmartKey in the ignition to
position 0 (
୴ page 40).
̈ 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.
̈ After driving vehicle for an initial
10 minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.
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.
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 placards on driver’s door B-pillar
or on fuel filler flap), and drive vehicle to
nearest tire repair facility to have tire re-
paired or replaced.
