What this warning means
A warning light identifies a system, condition, or protection strategy. It does not authorize a parts replacement by itself.
A warning lamp signals a condition or protection strategy. Its color, behavior, messages, and companion symptoms control urgency.

- 02AssessCheck all tire pressures cold against the vehicle placard, inspect for damage, and treat a flashing-then-steady lamp as a possible system fault after pressure is verified.

- 04CheckMeasure each tire with a known-good gauge before driving farther than necessary. / Inspect tread, sidewalls, valve areas, and the spare if the vehicle monitors it.

Record the exact symbol, color, steady-versus-flashing behavior, messages, and other lamps before clearing evidence.
Safe first checks
Measure each tire with a known-good gauge before driving farther than necessary.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Inspect tread, sidewalls, valve areas, and the spare if the vehicle monitors it.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Record whether the lamp is steady or flashes first and whether a tire was recently serviced.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.
Use exact sensor frequency, registration, and relearn information for the vehicle.

Safety boundary
Tire condition is a safety issue
Do not drive on a visibly damaged, severely underinflated, or rapidly leaking tire. The vehicle placard and exact tire information control pressure decisions.
