Sealing tires with TIREFIT
Small tire punctures, particularly those in
the tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Foreign objects (e.g. screws or nails)
should not be removed from the tire.
Take TIREFIT, the sticker, and the
electric air pump out of the trunk.
Attach the sticker where it will be easily
seen by the driver on the instrument
cluster.
!A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
iOpen door only when conditions are safe to
do so.
Warning!G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage 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
circumstances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance.
!After using TIREFIT, the tire inflation
pressure sensor may have to be replaced.

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
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.
Warning!G
Have worn or damaged tires replaced in
pairs (front pair or rear pair) an make sure
the tires rotate in the direction specified

ty of the vehicle will be adversely affected,
especially when driving at high speeds.
