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.
- 01IdentifyOIL · stop urgency
- 02AssessIf the warning remains on while the engine is running, stop as soon as it is safe, switch the engine off, and do not diagnose by continuing to drive.
- 03PreserveWarning timing / Oil level and visible leakage
- 04CheckConfirm whether the warning appears only during the normal key-on self-check or while the engine is running. / Look for a low oil level or fresh leakage only after the engine is off and safe to inspect.
- 05VerifyFollow the vehicle source and confirm the warning stays resolved
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.

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.
