2015 Cadillac ATS Owner Manual - Page 254

Driving and Operating If equipped with an Electric Parking Brake (EPB), the switch is on the center console for manual transmission vehicles, or on the left side of the instrument panel for automatic transmission vehicles. The EPB can always be activated, even if the ignition is off. To prevent draining the battery, avoid repeated cycles of the EPB when the engine is not running. The system has a red parking brake status light and an amber parking brake warning light. See Parking Brake Light on page 5-19 and Service Electric Parking Brake Light on page 5-19. There are also parking brake-related Driver Information Center (DIC) messages. See Brake System Messages on page 5-33. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied. 9-31 EPB Apply To apply the EPB: 1. Be sure the vehicle is at a complete stop. 2. Lift up the EPB switch momentarily. The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come one, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. See Parking Brake Light on page 5-19. If the amber parking brake warning light is on, lift up on the EPB switch and hold it up. Continue to hold the switch until the red parking brake status light remains on. If the amber parking brake warning light is on, see your dealer. If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is held up. If the switch is held up until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement. EPB Release To release the EPB: 1. Place the ignition in the ACC/ ACCESSORY or ON/RUN/ START position. 2. Apply and hold the brake pedal.
