Your dashboard lights automatically illuminate when your engine starts, and then they should go dark in seconds. If one of these lights remains on, though, it’s a sign that one of the systems isn’t working correctly and needs to be checked ASAP. As your GMC dealer, we want to tell you about some of your GMC dashboard lights and the issues an illuminated light can represent.

Battery Warning
This light looks like a line drawing of a battery and lights up if there’s a problem with the electrical system. It could represent a weak alternator, a failing battery, blown fuses, or damaged wiring. Our technicians can swiftly trace and repair any electrical issue.
Check Engine Light
This light appears as a line drawing of the side view of a car engine. It’s your most important light, as it illuminates if something is affecting your engine. This covers a very broad range of systems, including the transmission and catalytic converter.
A blocked converter, for example, decreases engine performance as the blockage forces more gases back into the engine. A lit engine light needs to be investigated ASAP, as it could result in permanent engine damage.
Brake Warning Light
This light looks like an exclamation point in a circle inside brackets or the word BRAKE, depending on your model. It warns of a potential issue in the braking system, ranging from a still-engaged hand brake to a worn caliper.
ABS Warning Light
The ABS light appears as the letters ABS in a circle inside brackets, and it means your ABS isn’t working correctly. The ABS (Anti-Lock Braking System) prevents your wheels from locking if you spin on a wet or muddy surface. It doesn’t affect regular braking, but it makes driving less safe until the cause of the problem is repaired.
Low Fuel Indicator
If you’re low on gas, this warning light illuminates as a reminder. It looks like a gas pump.
Oil Warning Light
The oil warning light illuminates if your engine oil is low or it’s old and needs to be changed. Low or old oil can cause engine damage, so we advise visiting us right away so we can fix the issue. Its icon is an oil can.
Temperature Warning Light
This looks like a thermometer with water underneath. This indicator lights up if something is wrong with your cooling system. It could be caused by several issues, including low coolant, a blocked radiator, or a failed water pump. Contact us immediately, as a malfunctioning cooling system can cause your engine to overheat within minutes.
