What do my dashboard warning lights mean?

Car warning lights
  • A red warning light on the instrument panel indicates a serious car problem or a safety issue and should be checked straightaway
  • The cause of an orange warning light should be checked as soon as you’re able
  • Consult the owner’s manual for explanation or call NRMA motoring advice on 13 11 22 

The electronic system in today’s cars relies on a series of sensors – these sensors can also tell you if there’s something wrong with your car using warning symbols on the dashboard.

There are two types of warning lights – red and orange. A red warning light suggests that you should act quickly because the problem is serious, such as an overheating engine, low engine oil pressure or a braking system problem.

An orange warning light means that the engine management system – the computer that runs the engine – has detected a fault. You may continue to drive, but you should take your car to your local service centre for diagnosis and repair as soon as possible.

It’s important to pay attention to car dashboard warning lights because they can help you avoid a car breakdown, as well as potentially saving you from an expensive repair bill and keeping you safe on the road.

If a red or orange warning light appears on your dash, don’t ignore it. Instead, pull over somewhere safe and look up what it means in your owner’s manual.

If you’re not sure what the problem is, call roadside assistance or ask your NRMA car service centre for advice.

If a light momentarily illuminates then disappears, there may not be a problem, but it is a good idea to get it checked out at NRMA car servicing for peace of mind.
