Using the TIREFIT kit - EQB SUV October 2024 X243 MBUX Owner's Manual

Requirements:

    • Tire sealant bottle and tire inflation compressor are ready for use (TIREFIT kit storage location) .
    • TIREFIT sticker is displayed.
    • Gloves are at hand.

You can use TIREFIT tire sealant to seal perforation damage of up to0.16 in(4 mm), particularly on the tire contact surface. You can use TIREFIT in outside temperatures down to-4 °F(-20 °C).


The tire sealant may be unable to seal the tire properly, especially in the following cases:

    • There are large cuts or punctures in the tire (larger than damage previously mentioned)
    • The wheel rims have been damaged
    • After journeys with very low tire pressure or with flat tires
Do not continue driving.
Consult a qualified specialist workshop.


The tire sealant is harmful and causes irritation. Do not allow it to come into contact with the skin, eyes or clothing, and do not swallow it. Do not inhale tire sealant fumes. Keep the tire sealant away from children.

If you come into contact with the tire sealant, observe the following:

Rinse off the tire sealant from your skin immediately using water.
If tire sealant gets into your eyes, thoroughly rinse out the eyes using clean water.
If tire sealant has been swallowed, immediately rinse out the mouth thoroughly and drink plenty of water. Do not induce vomiting and seek medical attention immediately.
Change out of any clothes contaminated with tire sealant immediately.
If allergic reactions occur, seek medical attention immediately.


Do not run the tire inflation compressor for longer than ten minutes without interruption.

Observe the manufacturer's safety notes on the sticker on the tire sealant bottle.

Have the tire sealant bottle replaced at a qualified specialist workshop every five years.

Do not remove any foreign objects that have pierced the tire.
Flat tire - Using the TIREFIT kit
Remove sticker1from the tire inflation compressor housing and affix it to the driver display within the driver's field of vision.
Flat tire - Using the TIREFIT kit
Remove sticker2from the tire sealant bottle and affix it near the valve on the wheel with the defective tire.
Flat tire - Using the TIREFIT kit
Pull plug7with cable and filling hose3out of the tire inflation compressor housing.
Insert the tire sealant bottle9into the socket6of the tire inflation compressor so that the red arrow on the tire sealant bottle9aligns with the red arrow on the tire inflation compressor.
Rotate the tire sealant bottle9clockwise for a quarter of a turn.
Insert the plug of the filling hose3into the socket5of the tire sealant bottle9.
Rotate the filling hose3clockwise for a quarter of a turn.
Flat tire - Using the TIREFIT kit
Remove the valve cap from the valveAon the faulty tire.
Screw the union nut4of the filling hose3onto the valveA.
Flat tire - Using the TIREFIT kit
Insert the plug7into a 12 V socket in your vehicle (Using the 12 V socket) .
Switch on the vehicle.
Press the On/Off switch8on the tire inflation compressor.

The tire inflation compressor is switched on. The tire is inflated. First, tire sealant is pumped into the tire. The pressure may briefly rise to approximately 500 kPa (5 bar/73 psi).

Do not switch off the tire inflation compressor during this phase!

Allow the tire inflation compressor to run for a maximum of ten minutes.

The tire should then have attained a tire pressure of at least 200 kPa (2.0 bar/29 psi).

If tire sealant leaks out, ensure that the affected area is cleaned as quickly as possible. It is preferable to use clean water.

If you get tire sealant on your clothing, have it cleaned at a dry cleaner's as soon as possible with perchloroethylene.

If after ten minutes a tire pressure of 200 kPa (2.0 bar/29 psi) has not been attained:

Switch off the tire inflation compressor.
Unscrew the filling hose from the valve of the defective tire.

Please note that tire sealant may leak out when unscrewing the filling hose.

Drive the vehicle forwards or in reverse very slowly for approximately33 ft(10 m).
Pump up the tire again.

After a maximum of ten minutes, the tire pressure must be at least 200 kPa (2.0 bar/29 psi).


If the specified tire pressure is not achieved after the specified time, the tire is too badly damaged. The tire sealant cannot repair the tire in this instance.

The braking characteristics as well as the driving characteristics may be greatly impaired.

Do not continue driving.
Consult a qualified specialist workshop.


After use, excess tire sealant may leak out from the filling hose.

Therefore, place the filling hose in the plastic bag that contained the TIREFIT kit.

If after ten minutes a tire pressure of 200 kPa (2.0 bar/29 psi) has been attained:

Switch off the tire inflation compressor.
Unscrew the filling hose from the valve of the defective tire.

Please note that tire sealant may leak out when unscrewing the filling hose.


A tire temporarily sealed with tire sealant impairs the handling characteristics and is not suitable for higher speeds.

Adapt your driving style accordingly and drive carefully.
Do not exceed the maximum speed limit with a tire that has been repaired using tire sealant.

Observe the maximum permissible speed of50 mph(80 km/h)for a tire sealed with tire sealant.
The sticker with details of the maximum permissible speed must be affixed to the instrument cluster where it can be easily seen by the driver.

After use, excess tire sealant may leak out from the filling hose.

Therefore, place the filling hose in the plastic bag that contained the TIREFIT kit.


Tire sealant contains pollutants.

Have the tire sealant bottle disposed of professionally, e.g. at an authorized Mercedes-Benz Center.

Stow the tire sealant bottle and the tire inflation compressor.
Pull away immediately.
Stop driving after approximately ten minutes and check the tire pressure using the tire inflation compressor.

The tire pressure must now be at least 130 kPa (1.3 bar/19 psi).


If the specified tire pressure is not reached, the tire is too badly damaged. The tire sealant cannot repair the tire in this instance.

The braking and driving characteristics may be greatly impaired.

Do not continue driving.
Consult a qualified specialist workshop.

In cases such as the one mentioned above, contact a Mercedes-Benz Service Center. Or call1-800-FOR-MERCedes(in the USA) or1-800-387-0100(in Canada).

Correct the tire pressure if it is still at least 130 kPa (1.3 bar/19 psi). For values, refer to the tire data and load data plate on the B‑pillar on the driver's side or the tire pressure table on the fuel filler flap.

Increasing the tire pressure

Switch on the tire inflation compressor.

Decreasing the tire pressure

Remove the tire sealant bottle from the tire inflation compressor.
Insert the filling hose into the socket of the tire inflation compressor and rotate it clockwise a quarter of a turn.
Flat tire - Using the TIREFIT kit
Press the pressure release buttonCnext to the manometerB.

When the tire pressure is correct

Unscrew the filling hose from the valve of the sealed tire.
Screw the valve cap onto the valve of the sealed tire.
Stow the tire sealant bottle and the tire inflation compressor.
Drive to the nearest qualified specialist workshop and have the tire, tire sealant bottle and filling hose replaced.
