Refer to the tire inflation tables for the correct inflation pressure. If the tire needs to be inflated, start the tire sealing system's compressor (press the on/off switch to position I). If necessary, release air from the tire by turning the air release knob counterclockwise. Tire Pressure Monitoring System (TPMS)-U.S models only NOTE USA - FCC ID: KR5S122780002 This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS SYST SERVICE REQUIRED will be displayed. CAUTION The compressor should not be used for more than 10 minutes at a time to avoid overheating. 9. Turn off the compressor (press the on/off switch to position 0) when the correct inflation pressure has been reached. 10. Unscrew the hose from the tire's inflation valve and reinstall the valve cap. 11. Disconnect the electrical wire from the 12-volt socket. The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When the vehicle is moving at a speed of approximately 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a receiver located in the vehicle. When low inflation pressure is detected, TPMS will light up the tire pressure warning light ) (also referred to as a telltale) in the ( instrument panel and will display one of the following messages in the text window: LOW TIRE PRESS. CHECK TIRES or VERY LOW TIRE PRESSURE. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv`` 06 263
