What is a common alternative name for the Malfunction Indicator Light (M.I.L)?

The Malfunction Indicator Light (M.I.L) is commonly referred to as the "Service Engine Soon" light. This term is widely recognized and used by drivers and automotive professionals alike to indicate that there is an issue with the vehicle's engine or emissions system that needs attention. When illuminated, the light serves as an alert to the driver that the vehicle's onboard diagnostics have detected a potential problem that could affect performance or emissions compliance.

The other options represent various warning lights that alert drivers to specific issues unrelated to the general engine performance or emissions signaling. For example, the low oil pressure light indicates a problem with the engine's oil supply, the brake warning light signals issues related to the braking system, and the battery warning light indicates issues with the vehicle's electrical system or battery condition. Each of these lights serves a distinct purpose, whereas the "Service Engine Soon" light specifically addresses engine or emissions faults, making it synonymous with M.I.L.
