14. Vehicles with steel rims (Canada only)
Installation of wheel cover:
Position small wheel cover opening over tire valve
and press wheel cover against wheel rim. Now press
(do not hit) opposite side of wheel cover against
wheel rim until seated. Make certain that the
springs of the wheel cover are firmly seated in the
outer rim of the steel wheel.Notes:
Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of vehicle jack see page 325.

Wa r n i n g !
Always replace wheel bolts that are damaged or
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired
immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.

(C 32 AMG only)
Small punctures, particularly those in the tread can be
sealed with TIREFIT.
Foreign objects (e.g. screws or nails) should not be
removed from the tire.
TIREFIT can be used in ambient temperatures down to
approx. - 4
°F (- 20
°C).
Wa r n i n g !
Cuts or punctures larger than approx. 0.16 in
(4 mm), tire damage caused by driving with
extremely low tire pressure or on a flat tire, or a
damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances.Do not drive the vehicle under such circumstances.Contact your nearest Mercedes-Benz Center for
assistance.Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes or clothing.
TIREFIT is harmful if inhaled, swallowed or
absorbed through the skin - causes skin, eye and
respiratory irritation.
Any contact with eyes or skin should be flushed
immediately with plenty of water.If clothing comes in contact with TIREFIT, change
clothing as soon as possible.In case of allergic reaction or rash, consult a
physician immediately.Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with plenty
of water and drink plenty of water.Do not induce vomiting!Consult a physician immediately.Keep away from open flame or heat source.

Sealing tire with TIREFIT
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
3. Take TIREFIT out of trunk, see page 326.
4. Shake contents of TIREFIT container.
Screw hose (1) on to TIREFIT container.
TIREFIT is now ready for use.5. Unscrew valve tire cap. Remove tire valve (2) using
valve stem r emoval tool (3 ). Do n ot p lace tir e valve in
sand or dirt.

(1) onto valve stem.
7. Hold container upside down (hose down) and
squeeze entire contents of container into tire.
8. Pull hose (1) off and screw tire valve (2) using valve
stem tool (3) into the valve stem.
Note:
A spare tire valve is stored with the valve stem tool.
9. Install plug (4) onto end of hose (1).
10. The air pump is located inside the wheel well in the
trunk. Observe instructions on air pump label.

11. Remove air pump from storage compartment inside
trunk.
12. Pull out air hose with pressure gauge (5) and
electrical plug (6).
13. Screw filler hose (5) onto tire valve.
14. Plug air pump electrical plug (6) into vehicle cigar
lighter.
15. To switch on air pump, turn key in steering lock to
position 1.
Note:
After 5 minutes, pressure gauge must display
26 psi (1.8 bar). Do not exceed the maximum pressure
of 36 psi (2.5 bar)!
If pressure is not attained, drive vehicle
approx. 394 in (10 m), so that the sealing material is
evenly distributed inside the tire. Reconnect air pump
and inflate tire.Note:
Do not operate electric air pump longer that 6 minutes
wit hout interruption. Air pump could overheat! Af ter air
pump has cooled off, operate air pump again.
16. To switch off air pump, turn key in steering lock to
position 0.
17. Reinstall valve tire cap.
18. Drive vehicle to distribute the sealant evenly inside
the tire.
Wa r n i n g !
If a tire 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 can not properly seal the tire.Do not drive the vehicle.Contact the nearest Mercedes-Benz Center or call
Roadside Assistance.

cluster displayPractical hintsCar care Index Notes:
If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material had dried,
it can easily be peeled off and properly discarded.
Replace TIREFIT every 3 years.Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18
°F (10
°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68
°F (+20
°C)
and ambient temperature = approximately +32
°F (0
°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
Wa r n i n g !
Do not exceed vehicle speed of 50 mph (80 km / h).
A TIREFIT repair is not designed to operate at
higher speeds.Vehicle handling characteristics may change.After driving vehicle for an initial 10 minutes,
check tire pressure. If tire pressure has fallen
below 20 psi (1.3 bar) do not continue to drive the
vehicle.If tire pressure is at least 20 psi (1.3 bar), inflate
tire to correct pressure (see label on fuel filler
flap), and drive vehicle to nearest tire repair
facility to have tire repaired or replaced.Recommended duration of use: 300 miles (500 km)
at 50 mph (80 km / h) with the recommended tire
pressure.
