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.

warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.
If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment on the right hand side.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight as indicated by the label on
the driver’s door latch post). Overloading the tires
can overheat them, possibly causing a blowout.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clot hin g. In cas e i t d oes , i mm ed ia tely f lus h a f fected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc.
