Driving and Operating Driver Information Center (DIC) messages. See Brake System Messages on page 5‑29 for more information. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the parking brake status light to ensure that the parking brake is applied. If the EPB is applied while the vehicle is in motion, a chime will sound, and a DIC message will be displayed. The vehicle will decelerate as long as the switch is held in the up position. Releasing the EPB switch during 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 parking brake status light flashes continuously, then the EPB is only partially applied or released, or there is a problem with the EPB. A DIC message 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. If the parking brake warning light is on, the EPB has detected an error in another system and is operating with reduced functionality. To apply the EPB when this light is on, lift up on the EPB switch and hold it in the up position. Full application of the 9-33 parking brake by the EPB system may take a longer period of time than normal when this light is on. Continue to hold the switch until the parking brake status light remains on. If the parking brake warning light is on, see your dealer. For maximum EPB force when parking on a hill, pull the EPB switch twice. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement. 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 parking brake status light will be on. While the brake is being applied, the status light will flash until it is fully applied. If the light does not come on, or remains flashing, you need to have the vehicle serviced. Do not drive the vehicle if the parking brake status light is flashing. See your dealer. See Electric Parking Brake Light on page 5‑18 for more information. EPB Release To release the EPB, place the ignition in the ACC/ACCESSORY or ON/RUN position, apply and hold the brake pedal, and push down momentarily on the EPB switch. If you attempt to release the EPB without the brake pedal applied, a chime will sound, and a DIC message will be displayed. The EPB is released when the parking brake status light is off.
