Tire pressure light is on
A steady light means at least one tire is low on air; if all four look normal, you can usually drive slowly to the nearest air pump and fill them to the number on the door-jamb sticker. If a tire keeps losing air or looks flat, don't drive on it, because it likely has a puncture or a leaking valve.

Likely causes
- A cold snap lowering the pressure in every tire
- A nail, screw or other puncture
- A leaking valve stem
- A damaged wheel or a leak where the tire meets the rim
- A faulty sensor (the light flashes, then stays on)
Try this first
- Walk around the car and look at all four tires
- Check each tire with a gauge and compare it to the door-jamb sticker
- Add air at a gas station pump if the tires look normal
- Look for a nail or screw head in the tread
- If the light flashes for about a minute at start-up, have the sensor system checked
When to call us
- One tire is visibly low or flat

Questions
01Can I drive with the tire pressure light on?
If the tires look normal, drive slowly to an air pump and fill them. Don't drive any distance on a tire that looks flat; that can damage it beyond repair.
02Why did the light come on when the weather turned cold?
Air contracts in the cold, so tire pressure drops on chilly mornings. Filling to the recommended pressure usually turns the light off after a short drive.
