Driving and Operating Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal. 9-33 Parking Brake 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 parking brake status light and a parking brake warning light. See Electric Parking Brake Light on page 5‑20. There are also three Driver Information Center (DIC) messages. See Brake System Messages on page 5‑33 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. Braking in Emergencies ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking. The vehicle has an Electric Parking Brake (EPB). The switch for the EPB is in the center console.
