Low tire pressure warning light, low tire pressure warning position
Low tire pressure warning light:

Low tire pressure warning position indicator:

When the Tire Pressure Monitoring System warning light comes on, one or more of your tires is significantly under-inflated. The low tire pressure warning light will indicate which tire is significantly under-inflated by illuminating the corresponding position light.
If any warning light comes on, immediately reduce speed, avoid sharp turns, and anticipate longer braking distances. You should stop and check your tires as soon as possible. Inflate the tires to the correct pressure specified on the tire placard or the tire pressure label located on the driver's side center pillar. If you cannot reach a service station or if the tire does not hold the added air, replace the under-inflated tire with the spare tire. If you drive the vehicle for about 10 minutes at speeds above 25 km/h after replacing the under-inflated tire with the spare tire, the following will occur:
• The TPMS malfunction indicator may flash for approximately 1 minute and then remain continuously illuminated, because the TPMS sensor is not installed on the spare tire.
CAUTION
In winter or cold weather, the low tire pressure warning light may come on if the tire pressure was adjusted to the recommended tire pressure in warm weather. This does not mean the TPMS is malfunctioning, because a drop in temperature causes a proportional decrease in tire pressure.
When you drive your vehicle from a warm area to a cold area, or from a cold area to a warm area, or if the outside temperature changes significantly, you should check the tire pressure and adjust the tires to the recommended tire pressure.
CAUTION - Low Pressure Damage
Significantly low tire pressure causes the vehicle to be unstable and may lead to loss of vehicle control and increased braking distance.
Continued driving on a low tire may cause the tire to overheat and fail.
