Grade Braking Grade Braking assists when driving on a downhill grade. It maintains the vehicle's speed by automatically implementing a shift schedule that uses the engine and the transmission to slow the vehicle. This reduces wear on the brakes system and increases control of the vehicle. The system constantly monitors the vehicle's speed, acceleration, throttle position, and whether the brake pedal is being pressed, and determines when to keep the current vehicle speed or to slow down. The system will then automatically command downshifts that reduces the vehicles speed, until the brake pedal is no longer being pressed. This indicates the desired vehicle speed has been reached. The tow/haul mode and grade braking shift modes can be activated by pressing the button on the instrument panel console. While in the DSC mode, grade braking is deactivated, allowing the driver to select a gear. See Automatic Transmission Operation on page 122. Parking Brake The parking brake pedal is located on the lower portion of the instrument panel to the left of the steering wheel. To set the parking brake, hold the regular brake pedal down with your right foot and push the parking brake pedal down with your left foot. If the ignition is on, the brake system warning light on the instrument panel cluster should come on. If it does not, you need to have your vehicle serviced. See Brake System Warning Light on page 204 for more information. 127
