8-32 Driving and Operating There are also three Driver Information Center (DIC) messages. See Brake System Messages on page 4‑33 for more information. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the park brake status lamp to insure the park brake is applied. If the EPB is applied while the vehicle is in motion, a chime will sound, and the DIC message RELEASE PARK BRAKE SWITCH will be displayed. The vehicle will decelerate as long as the switch is held in the up position. Releasing the EPB switch during the deceleration will release the parking brake. If the switch is held in the up position until the vehicle comes to a stop, the EPB will remain applied. If the park brake status light flashes continuously, the EPB is only partially applied or released, or there is a problem with the EPB. The DIC message SERVICE PARK BRAKE will be displayed. If this light flashes continuously, release the EPB, and attempt to apply it again. If this light continues to flash, do not drive the vehicle. See your dealer/ retailer. Parking Brake EPB Apply The EPB can be applied any time the vehicle is stopped. The EPB is applied by momentarily lifting up on the EPB switch. Once fully applied, the park brake status light will be on. While the brake is being applied, the status lamp will flash until full apply is reached. If the light does not come on, or remains flashing, you need to have the vehicle serviced. Do not drive the vehicle if the park brake status light is flashing. See your dealer/retailer. See Electric Parking Brake Light on page 4‑20 for more information. The vehicle has an Electric Parking Brake (EPB). The switch for the EPB is in the center console. The EPB can always be activated, even if the ignition is OFF. To prevent draining the battery, avoid repeated cycles of the EPB system when the engine is not running. The system has a Park Brake Status light and a Park Brake Warning light. See Electric Parking Brake Light on page 4‑20.
