A warning light can be a small reminder or a serious alert. Knowing the main ones helps you decide whether to keep driving or stop right away.

Red lights: stop safely

Red usually means a serious problem. Pull over as soon as it is safe.

  • **Oil pressure:** the engine may not be getting oil. Stop and turn it off.
  • **Engine temperature:** the engine is overheating. Pull over and let it cool.
  • **Brake system:** the brakes may be failing or the fluid is low.
  • **Battery or charging:** the car may stop running soon.

Yellow or amber lights: have it checked soon

Amber usually means something needs attention but is not an emergency.

  • **Check engine:** a steady light means a problem to check soon. A flashing light means a serious misfire and you should stop.
  • **Tire pressure:** at least one tire is low.
  • **ABS:** the anti-lock brakes are off, but normal braking still works.

Green or blue lights

These are information lights, such as headlights or cruise control.

What to do when a light comes on

  1. Note the color and the symbol.
  2. If it is red, pull over safely and stop.
  3. Check the owner's manual.
  4. If you are not sure, call for help or a tow.

Do not ignore a flashing light

A flashing check engine light or a red light with a sound is a sign to stop driving, not to wait.

Frequently asked questions

Can I drive with the check engine light on?

If it is steady and the car drives normally, you can drive carefully to a shop. If it flashes, stop.

Why did a light come on and then go away?

Some faults come and go. Have it checked anyway.

Can a dead battery cause warning lights?

Yes. A weak battery or charging problem can cause several lights at once.
