GMC Vehicle Service Warning Indicators
Boost your driving confidence by reading this page. It includes descriptions of dashboard warning lights commonly found on GMC models and other vehicles.
Airbag Fault
This light monitors your vehicle's supplemental restraint system, which includes your airbags and seat belts. When the light illuminates, you'll know that your vehicle's control module noticed a fault in your SRS. We recommend that you have this problem professionally repaired immediately. Until you do, improper airbag deployment is possible during an accident.
Low Fuel Level Warning Light
Treat this light as your reminder to stop for fuel. To estimate your remaining fuel amount, check your owner's manual.
Oil Pressure Warning Light
If your vehicle is running when this light appears, stop driving quickly and safely, and turn off your engine. Low oil pressure can cause significant friction damage. If you find that you need to add oil, use the correct viscosity. When your oil level is adequate, and the light remains, you will need a professional technician's help.
Service Vehicle Soon
This indicator's meaning varies by model, so please double check your owner's manual. On many vehicles, it's simply a reminder to perform periodic maintenance. Other autos use it to alert you to minor-repair needs.
TPMS (Tire Pressure Monitoring System)
You have low tire pressure if you see this light. Find an air hose, and adjust low tires appropriately. If the light does not turn off soon after you return to your drive, your TPMS sensors may need service.
Slip Indicator
If you lose traction, this light flashes to let you know your traction-restoring features are engaged. When the light illuminates despite perfect traction, seek professional service for a potential malfunction.
Charging System Warning Light
Your battery, alternator, and voltage regulator comprise your charging system, which supports the battery. This light indicates a fault in that circuit. Often, replacing your battery or alternator solves this problem.
Brake System
This indicator monitors your brake lines. If it appears, you most likely have air in your lines, or you have a fluid leak. For your safety, do not ignore this problem. We can expertly bleed and repair your brake lines.
Open Door Warning Light
You have a door open on your vehicle if this light appears. Never drive with open doors.
Coolant Level Warning
You should always take this light seriously. It warns you of low engine coolant. Immediately address the probable leak. Driving with low coolant destroys engines.
