07 Wheels and tires Tire Sealing System* NOTE The air pressure gauge will temporarily show an increase in pressure to approximately 88 psi (6 bar) while the sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately 30 seconds. 12. Switch off the compressor and disconnect the electrical wire from the 12-volt socket. 13. Unscrew the hose from the tire's inflation valve and reinstall the valve cap. 14. Immediately drive the vehicle for approximately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to distribute the sealing compound in the tire. WARNING If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the vehicle in a safe place. Recheck the tire for bumps, cracks, or other visible damage, and recheck its inflation pressure. If the pressure is below 19 psi (1.3 bar), do not continue driving. Have the vehicle towed to a trained and qualified Volvo service technician. 11. Within seven minutes, inflate the tire to between 22-44 psi (1.8-3.0 bar). Switch off the compressor briefly to get a clear reading from the pressure gauge. The compressor should not be used for more than 10 minutes at a time to avoid overheating. CAUTION If your vehicle is equipped with the Tire Pressure Monitoring System (TPMS), the use of the sealing compound may lead to incorrect tire pressure readings or in rare cases, damage to the tire pressure sensor. Use the tire sealing system to check and adjust the damaged tire's inflation pressure. Stage 2: Checking inflation pressure 1. Connect the tire sealing system as described in stage 1. 2. Refer to the inflation pressure tables for the correct inflation pressure. If the tire needs to be inflated, start the tire sealing system's compressor. If necessary, release air from the tire by turning the air release knob counterclockwise. CAUTION The compressor should not be used for more than 10 minutes at a time to avoid overheating. NOTE • WARNING 07 If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this case, the hole is too large to be sealed and the vehicle should not be driven. Safely stow the tire sealing system in a convenient place as it will soon be used again to check the tire's inflation pressure. The empty bottle of sealing compound cannot be removed from the bottle holder. Consult a trained and qualified Volvo service technician to have the bottle removed and properly disposed of. CAUTION The compressor should not be used for more than 10 minutes at a time to avoid overheating. • WARNING If you interrupt your trip for more than 1 hour, check the inflation pressure in the damaged tire again before continuing. 196 * Option/accessory, for more information, see Introduction.
