Know your dashboard warning lights

It’s no fun when your dashboard lights up like a Christmas tree, but what do those warning lights mean?

Dashboard icons

Your car’s dashboard has a myriad of icons which light up to either let you know something is operating or to warn you when something has gone wrong.

The average car has around 25 dashboard icons, while feature packed cars such as the Mercedes-Benz E-Class can have more than 40. The more complex the car, the more potential there is for mechanical or electronic carnage.

While many annunciator lights are easily recognisable, some icons are specific to certain cars, such as diesels and hybrids or four-wheel-drives. To add to the confusion there are also many new icons introduced along with new technology such as driver assist functions.

The first thing to take note is the colour as not all lights signify a problem. Red means something that requires immediate attention ranging from a door being open to low oil pressure, that can damage your car engine. In any case stop the car immediately and attend to the problem.

Orange usually signifies something that requires monitoring, such as low fuel, while green, blue and white generally show when something is switched on or operating automatically.

Think of it like traffic lights where red means stop, orange is caution, and green is go.
