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.

- 05VerifyFollow the vehicle source and confirm the warning stays resolved
Follow the sequence, stop when evidence changes the path, and verify the exact vehicle information before acting.
Record the exact symbol, color, steady-versus-flashing behavior, messages, and other lamps before clearing evidence.
Safe first checks
Confirm whether the warning appears only during the normal key-on self-check or while the engine is running.
Use the vehicle's owner/service information when the check depends on a location, specification, service mode, or scan-tool function.

Can you keep driving?
Safety boundary
Possible engine-damage condition
A warning sender can fail, but the safe assumption until tested is that lubrication may be inadequate. Do not run the engine to see whether the lamp goes away.
