You can use the TIREFIT kit to seal small punctures, particularly those in the tire tread.

You can use TIREFIT at outside temperatures down to -4 °F (-20 °C).

WARNING
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.

Contact the nearest authorized Mercedes- Benz Center for assistance or call Roadside Assistance.

•► Do not remove any foreign objects which have penetrated the tire, e.g. screws or nails.

•► Remove the tire sealant bottle, the accompanying "max. 80 km/h" sticker and the tire inflation compressor from the stowage well underneath the trunk floor/ trunk floor

•► Affix part 1 of the sticker within the driver's field of vision.

•► Affix part 2 of the sticker near the valve on the wheel with the defective tire.

WARNING
Take care not to allow the contents of TIREFIT to come in contact with hair, eyes or clothing.

In case of allergic reaction or rash, consult a physician immediately.

WARNING
Keep TIREFIT away from children. If swallowed, rinse mouth immediately with plenty of water and drink plenty of water.

Keep away from open flame or heat source.

If TIREFIT leaks out, allow it to dry. It can then be removed like a layer of film.

If you get TIREFIT on your clothing, have it cleaned as soon as possible with perchloroethylene.

•► Pull connector 4 with the cable and hose 5 out of the housing.

•► Screw hose 5 onto flange 6 of tire sealant bottle 1.

•► Insert tire sealant bottle 1 upside down into opening 2 on the tire inflation compressor.

•► Remove the cap from valve 7 on the defective tire.

•► Screw filler hose 8 onto valve 7.

•► Insert plug 4 into the cigarette lighter socket or into a 12 V socket in your vehicle

•► Turn the SmartKey to position 1 in the ignition lock.

•► Press on/off switch 3 on the tire inflation compressor to I.

The tire inflation compressor is switched on. The tire is inflated.

First, TIREFIT is pumped into the tire. The pressure can 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 five minutes. The tire should then have attained a pressure of at least 180 kPa (1.8 bar/26 psi).

Do not operate the tire inflation compressor for longer than eight minutes at a time without a break. It may otherwise overheat.

The tire inflation compressor can be operated again once it has cooled down.

If a pressure of 180 kPa (1.8 bar/26 psi) has been achieved after five minutes

If a pressure of 180 kPa (1.8 bar/26 psi) has not been achieved after five minutes
