Understanding Your Car's TPMS System

What Is TPMS?

Since 2007, all new US vehicles have TPMS to monitor tire pressure.

What to Do When the Light Comes On

1. Check all four tires visually

1. Use a gauge to check pressure

1. Add air to any low tires

1. If a tire loses pressure again, visit us for inspection

Temperature changes affect tire pressure — tires lose about 1 PSI for every 10°F drop.
