tire pressure light · low tire pressure light · tire pressure monitoring system light
A horseshoe-shaped light with an exclamation point means the tire pressure monitoring system has detected one or more tires below the recommended pressure. If it flashes for about a minute then stays on, the TPMS system itself has a fault rather than the tires.
Check all four tire pressures (including the spare on some systems) with a gauge and inflate to the pressure listed on the driver door jamb sticker, not the number on the tire sidewall. Inspect for punctures if a tire keeps losing air.
Yes, but check pressures soon - underinflated tires wear unevenly, hurt fuel economy, and increase blowout risk, especially at highway speed.

This warning light sometimes appears alongside these symptoms:
Check Engine Light
WarningThe engine control unit has detected a fault somewhere in the engine, transmission, or emissions system and stored a trouble code (a "P" code) explaining what went wrong.
Parking Brake Warning Light
WarningThis light most commonly just means the parking brake is engaged, but if it stays on after you release it, it can share the same circuit as the brake fluid warning.
ABS Warning Light
WarningThe anti-lock braking system has detected a fault and disabled itself. Normal brakes still work, but you lose anti-lock protection during hard braking.
Master Warning Light
WarningA general-purpose alert (usually a red or amber exclamation mark or triangle) that lights up alongside a specific message on the instrument cluster display, pointing to a variety of possible issues.
