Tire pressure light on
Low — fix soon
The tire pressure warning light (an exclamation mark inside a tire shape) stays on. One or more tires may be low on air.
Possible causes
- Low tire pressure — Most likely
Check first: Check all four tires with a pressure gauge, including the spare if it has a sensor. Look for a nail or screw in the tread. - Cold weather pressure drop — Possible
Check first: Remember that pressure drops about 1 psi for every 10 degrees colder. Inflate the tires to the number on the driver's door sticker. - Faulty tire pressure sensor — Less likely
Check first: If the light stays on after you inflate all tires to the correct pressure, a sensor in one wheel may be bad.
