Warning Lights Explained

Charge System Warning

Charge System Warning Example

If your GM has detected an issue with the power from the battery not making it to the electrical system this warning will appear.

It looks like a battery from the side with the positive and negative icons inside of it, most likely illuminated red.

The cause of this can range from a dying (or not sufficiently charged) battery through to a faulty alternator or even a problem with the wiring.


Brake Warning

Brake Warning Example

An icon showing the word BRAKE in capital letters illuminated red signifies a problem with the brakes.

It could be as simple as the parking brake (or handbrake as it’s known in some regions) being left on while attempting to drive off.

On the other end of the spectrum, it could be suggesting that a problem with the brake system has occurred and if this is the case seek professional help.


Oil Warning

Oil Warning Example

What looks like an old-fashioned oil lamp with a drip of oil coming from it could be a warning that you have an issue with your oil in the engine.

The severity of this can range from a temporary low pressure at the point of the sensor all the way through to a broken pump.

Try turning the car off and then on again to see if it persists, if it does then seek a trained GM mechanic.


Engine Temperature Warning

Engine Temperature Warning Example

A red illuminated icon showing a thermometer floating in a liquid is evidence of an overheating engine.

This may be temporary and by stopping and letting your GM cool down you could get rid of it.

If it persists then it is best to stop driving your car and let a mechanic look at it to avoid further damage.


Airbag Warning

Airbag Warning Example

If you see an icon that looks like the side profile of a passenger in a car with a large circle in front of them then this may mean there is a problem with one or more airbags.

Try turning your car off and on again to see if that fixes the error, if this doesn’t then seek a trained mechanic as soon as possible.


Security Indicator

Security Indicator Example

An icon showing the front of a car with a lock overlapping it represents the security warning indicator in a GM.

This warning can be quite vague as it can cover various security systems in different GM models.

It could be as simple as a low battery in your keyfob all the way through to a fault in your immobilizer.


Seat Belt Reminder

Seat Belt Reminder Example

A simple reminder icon that appears as a passenger with a set of seat belts around them is telling you that an occupant isn’t wearing their safety belt.

The car knows this by detecting weight on one or more car seats using a pressure pad underneath the seat.

If this light persists with no one sat on any of the seats and you have no cargo resting on them either then you may have a fault somewhere.


Tire Pressure Warning

Tire Pressure Warning Example

What looks like an exclamation mark in a vase-shaped icon is a warning concerning the tire pressures.

This may affect one or more tires and if you find that your tire pressures are in order then it may also represent a faulty sensor that needs replacing.
