Practical hints Flat tire Unscrew the valve cap from tire valve 7. Screw filler hose 10 onto tire valve 7. Insert electrical plug 4 into vehicle cigarette lighter socket. Turn key in steering lock to position 1 ( page 29). Press I on electric air pump switch 8. The electric air pump should now switch on and inflate the tire. After 5 minutes, the pressure gauge must display at least 26 psi (1.8 bar). The air hose can become hot during inflation. Please exercise appropriate caution. If this tire pressure is not attained, turn off the electric air pump, detach the filler hose from the tire valve, and drive vehicle back and forth very slowly approximately 30 ft (10 m). This serves to better distribute the TIREFIT sealant material inside the tire. Unscrew the air pump's air hose 5 from flange 6 of the TIREFIT container. Inflate the tire again. Warning! 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 cannot properly seal the tire. Do not drive the vehicle. Contact the nearest Mercedes-Benz Center or call Roadside Assistance. ! Do not operate the electric air pump longer than eight minutes without interruption. Otherwise it may overheat. You may operate the air pump again after it has cooled off. After attaining a tire pressure of 26 psi (1.8 bar), press 0 on electric air pump switch 8. The electric air pump should now be switched off. Turn key in steering lock to position 0 ( page 29). 236
