Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire.

GWarning!
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.
XAfter driving for approximately 5 miles
(3 km) or 10 minutes, stop the vehicle and
check the tire inflation pressure using the
electric air pump.
i The TIREFIT sealing may impair the
function of the sensors in the tire. Proper
operating sensors are necessary to check
the tire inflation pressure with the
Advanced Tire Pressure Monitoring
System. When the sensors are not
operating properly, the measured tire
inflation pressure may be inaccurate or the
tire inflation pressure may not be displayed
at all. Error messages may appear.
Therefore, check and adjust the tire
inflation pressure with pressure gauge 0087
on the electric air pump.
GWarning!
If tire inflation pressure has fallen below
130 kPA (1.3 bar, 20 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
Have the damaged tire replaced.
If the tire inflation pressure is at least 130 kPA
(1.3 bar, 20 psi), inflate or deflate the tire to
the correct tire inflation pressure (see Tire
and Loading Information placard on the
driver’s door B-pillar):XTo increase tire inflation pressure:
Switch on the electric air pump.XTo decrease tire inflation pressure:
Open vent screw 006E on air hose 0070.XDrive to the nearest qualified workshop,
e.g. an authorized Mercedes-Benz Center,
to have the damaged tire replaced.XContact an authorized Mercedes-Benz
Center as soon as possible to obtain a new
TIREFIT kit.XBring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.XReplace your TIREFIT container every
4 years. Replacement containers are
available at any authorized Mercedes-Benz
Center.
