Low Tire Pressure Warning Light

Low Tire Pressure Warning Light

When the tire pressure monitoring system warning light illuminates, the pressure in one or more tires is significantly below the specified value.
If the warning light illuminates, reduce speed immediately, avoid sharp turns and braking maneuvers, and anticipate increased braking distance. You should stop and check your tires as soon as possible.
Inflate the tires to the proper pressure indicated on the vehicle certification label or tire inflation pressure label located on the inside of the driver's side center pillar. If you cannot reach a service station or if the tire does not hold the newly added air, replace the low-pressure tire with the spare tire.
The TPMS malfunction indicator and low tire pressure warning light may change and illuminate after restarting and after approximately 20 minutes of continuous driving until you repair or replace the low tire on the vehicle.
In winter or in cold weather, the low tire pressure warning light may illuminate if the tire pressure was adjusted to the recommended tire pressure in warm weather. This does not mean that your TPMS is malfunctioning, as a decrease in temperature causes a proportional decrease in tire pressure.
When you drive the vehicle from a warm region to a cold region, or from a cold region to a warm region, or when the outside air temperature changes significantly, you should check the tire pressure and adjust the tires to the recommended tire pressure.
WARNING! Damage due to low pressure
Do not drive on underinflated tires. Significantly low tire pressure can cause the tires to overheat and fail, making the vehicle unstable, which leads to increased braking distance and loss of vehicle control.
CAUTION
When inflating tires with a large amount of air, the low tire pressure warning light may turn off before reaching the recommended pressure. This is because the tire inflator pump has an error in its output. The low tire pressure warning light will turn off if the tire pressure exceeds the recommended tire pressure.
