Stop safely for oil pressure, brake, coolant temperature, battery charging, or airbag warnings.
Check soon. The car may drive, but the fault should not be ignored.
A feature is active, such as lane assist, lights, or cruise-related systems.
Information, most often high beams. Adjust it for other drivers.
| Light | System | What to do |
|---|---|---|
| Oil pressure light | Engine oil | Pull over safely, shut the engine off, and check oil level. Do not keep driving with this light on. |
| Brake warning light | Brake | Check the parking brake first. If the light stays on or the pedal feels wrong, stop and get help. |
| Battery charging light | Charging | Turn off extra electrical loads and drive only far enough to reach a safe stop or service point. |
| Airbag light | SRS | Check seat belts and passenger-seat items. Have the SRS system scanned soon. |
| Coolant temperature light | Cooling | Pull over safely, turn the engine off, and let it cool. Do not open a hot coolant cap. |

Common questions
Why did several warning lights come on at once?
A weak battery, wheel-speed sensor fault, or communication problem can trigger several systems. Read the stored codes before replacing random parts.
Can I drive with a yellow warning light?
Often yes, but it depends on the symbol. Drive gently and schedule a check if the light stays on, flashes, or the car feels different.
Which warning lights mean stop now?
Oil pressure, coolant temperature, brake, charging, and flashing check-engine lights should be treated as stop-safely warnings.
