The vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking both parts need to be working.
If the warning light comes on, there is a brake problem. Have the brake system inspected right away.
Caution: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.
This light comes on briefly when the ignition key is turned to ON/RUN. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light will then go off.
When the ignition is on, the brake system warning light also comes on when the parking brake is set. The light stays on if the parking brake does not fully release. If it stays on after the parking brake is fully released, it means there is a brake problem.
The Driver Information Center (DIC) may display a BRAKE FLUID message. See DIC Warnings and Messages for more information.
If the light comes on while driving, pull off the road and stop carefully. The pedal may be harder to push or it may go closer to the floor. It may take longer to stop. Try turning off and restarting the vehicle one or two times, if the light is still on, have the vehicle towed for service. See Towing Your Vehicle .
