One helpful tip is to rely on color. Red lights usually indicate serious trouble, while yellow are closer to warning lights. Green lights are indicators (like high beams on).
Here are a few dashboard lights you should know:
Battery: Charge system trouble indicator
BRAKE (in all caps): Brake trouble indicator
Oil can: Oil warning
A P in a circle: Parking brake engaged
If your GMC is showing a dashboard light that you don’t recognize, check your owner’s manual for help.
