  3. TIRE PRESSURE WARNING SYSTEM PRECAUTION

    1. It is necessary for the tire pressures to be adjusted periodically because tire pressure decreases naturally over time.

    2. In winter, tire pressure may decrease due to low ambient temperatures (tire pressure decreases by approximately 10 kPa (0.1 kgf/cm2, 1.5 psi) for every 10°C (18°F) drop in the ambient temperature). Therefore, the tire pressure warning system is more likely to indicate a warning if the tire pressures are not adjusted appropriately. If the daily temperature variation is large, increase the pressure of the tires so that the tire pressures are suitable under cold conditions. As a result, unnecessary tire pressure warning operations should decrease.

    3. The system may not operate properly in the following conditions (when the conditions return to normal, the system will work properly).

      1. The vehicle speed is less than 40 km/h (25 mph).

      2. When different size tires from that which is specified are used.

      3. When tires of different manufacturers are used.

      4. When snow tires, a compact spare tire or tire chains are used.

      5. One of the tires on the vehicle is extremely worn or new.

      6. When aftermarket tire repair sealant is used.

      7. The vehicle is driven on unpaved, extremely rough or slippery roads.
