Instruments and Controls 5-25 Electric Parking Brake Light Service Electric Parking Brake Light This status light comes on when the parking brake is applied. If the light flashes and stays on after the parking brake is released, or while driving, there is a problem with the Electric Parking Brake system. If the light does not come on, or remains flashing, see your dealer. See Electric Parking Brake on page 9‑35 for more information. The Service Electric Parking Brake light should come on briefly when the vehicle is in ON/RUN. If it does not come on, have it fixed so it will be ready to warn if there is a problem. If this light stays on, there is a problem with a system on the vehicle that is causing the parking brake system to work at a reduced level. The vehicle can still be driven, but should be taken to a dealer as soon as possible. See Electric Parking Brake on page 9‑35 for more information. If a message displays in the Driver Information Center (DIC), see Brake System Messages on page 5‑46 for more information.
