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 starter switch
to position 0 (
୴ page 40).
̈ Detach the electric air pump.
The air hose may still be hot. Please
exercise appropriate caution.
̈ Store the electrical plug and the air
hose behind the flap and place the
electrical air pump back in the trunk.
̈ Close the trunk lid.
̈ Drive off 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.
̈ If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct
pressure (see placard on driver’s door
B-pillar) and contact a nearest qualified
workshop, e.g. an authorized
Mercedes-Benz Center, to have the
damaged tire replaced.
Recommended duration of use:
A maximum of 300 miles (500 km) at
or below 50 mph (80 km/h) with the
recommended tire inflation pressure.
Warning! G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, the 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.
Have the damaged tire replaced.
