Warning Lights Explained

[GMC] Charge System Warning

[GMC] 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.


[GMC] Brake Warning

[GMC] 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.


[GMC] Oil Warning

[GMC] 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.


[GMC] Engine Temperature Warning

[GMC] 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.


[GMC] Airbag Warning

[GMC] 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.


[GMC] Security Indicator

[GMC] 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.


[GMC] Seat Belt Reminder

[GMC] 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.


[GMC] Tire Pressure Warning

[GMC] 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.


About Buick

Buick Logo

Buick warning lights can be a little confusing to decipher. There are many different indicators that all have their own meanings and you should know what they mean. On this page, we will take a look at the car’s warning lights and how to understand them better.

The warning light that is most important to know about in detail is the ABS, airbag, check engine and transmission. The ABS light is red when it comes on. This means there has been a problem with your anti-lock brake system (ABS) and you must stop the car as soon as possible.

History of Buick

Buick Motors was founded in 1899. The headquarters of Buick is located in Detroit, Michigan.

Buick is one of the oldest American car brands still in production. It was founded by David Dunbar Buick and acquired shortly after its establishment by General Motors (GM).

The company manufactures vehicles for the American market that are mostly gasoline-powered sedans, coupes, and station wagon models.

They also offer SUVs and crossovers such as the Enclave and Encore that make up a large share of their sales in recent years.

The company has an extensive history of producing powertrain components such as engines for other car companies like Cadillac and GMC.

Buick was one of the first automobile manufacturers to offer a fully automatic transmission in 1940.
