Understanding Engine Warning Lights — What They Really Mean
Don't Ignore Your Dashboard
Modern vehicles are equipped with sophisticated onboard computers (OBD systems) that monitor hundreds of parameters in real time. When something falls outside normal range, a warning light appears. Here's a guide to the most important ones.
Red Lights — Act Immediately
- Oil pressure warning – Stop the engine as soon as it is safe to do so. Driving with low oil pressure can destroy your engine within minutes.
- Engine temperature – Your engine is overheating. Pull over, switch off, and let it cool before checking the coolant level.
- Battery warning – The charging system has failed. You may have limited time before the car stops running entirely.
Amber Lights — Attend Soon
- Check engine (MIL) – Could be anything from a faulty oxygen sensor to a misfire. Get a diagnostic scan to read the fault codes.
- Traction control / ABS – A fault in the stability or braking system. Safe to drive carefully but should be inspected.
- Service due – Your vehicle has reached its service interval. Book a service before the next long journey.
