07 Wheels and tires Tire Sealing System 7. Connect the electrical wire to the nearest 12-volt socket in the vehicle. 8. Start the vehicle's engine. 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. Unscrew the hose from the tire's inflation valve and reinstall the valve cap. 13. 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 The vehicle´s engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be sure the vehicle is parked in a well ventilated place, or outdoors, before using the system. CAUTION 10. 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. 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. 9. Start the tire sealing system's compressor by pressing the on/off switch to position I. CAUTION The compressor should not be used for more than 10 minutes at a time to avoid overheating. WARNING • • • Never stand next to the tire being inflated when the compressor is in operation. If cracks, bubbles, etc. form on the tire, switch off the compressor immediately. If there is visible damage to the sidewall or the rim, the tire cannot be repaired. The vehicle should not be driven if this occurs. Contact a towing service or Volvo On Call Roadside Assistance if applicable. NOTE • WARNING 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. 07 • 11. Switch off the compressor and disconnect the electrical wire from the 12-volt socket. `` 305
