In brief:
- The red oil pressure light requires an immediate stop of the vehicle.
- A flashing engine light is more serious than a steady one.
- The ABS light does not require an immediate stop but needs a quick check.
Understanding the warning light color code
Dashboard warning lights follow a standardized color code: red for immediate danger, orange for an issue to monitor, green or blue for simple information.
Red lights: stop immediately
- Oil pressure: risk of engine failure within minutes
- Engine temperature: risk of overheating and head gasket failure
- Braking: partial or total loss of braking efficiency
Orange lights to monitor
| Light | Meaning | Urgency |
|---|---|---|
| Engine (steady) | Engine or emissions issue | Diagnostic within a few days |
| Engine (flashing) | Misfire, catalytic converter risk | Stop recommended |
| ABS | Anti-lock system disabled | Check within 1 to 2 weeks |
| Airbag | Safety system malfunction | Quick diagnostic |
What to do in case of doubt
In case of an unknown light or doubt, checking the vehicle manual remains the most reliable reflex, as each model has its own display specifics.
After a repair: keep the record
Keeping the invoice for each intervention feeds the vehicle’s maintenance logbook, which matters when reselling. See our maintenance schedule.
