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.

Tempera t u re
The temperature grades are A (the highest), B, and C, 
representing the tire‘s resistance to the generation of 
heat and its ability to dissipate heat when tested under 
controlled conditions on a specified indoor laboratory 
test wheel. Sustained high temperature can cause the 
material of the tire to degenerate and reduce tire life, 
and excessive temperature can lead to sudden tire 
failure. The grade corresponds to a level of performance 
which all passenger car tires must meet under the 
Federal Motor Vehicle Safety Standard No. 109. Grades 
B and A represent higher levels of performance on the 
laboratory test wheel than the minimum required by 
law.
Wa r n i n g !
The temperature grade for this tire is established 
for a tire that is properly inflated and not 
overloaded. Excessive speed, underinflation, or 
excessive loading, either separately or in 
combination, can cause excessive heat build up 
and possible tire failure.
