The vehicle may be equipped with a Tow/Haul mode. The button is located on instrument panel under the climate controls. You should use this feature to assist when towing or hauling a heavy load.
When Tow/Haul is activated the Tow/Haul symbol will illuminate on the instrument panel cluster. See Tow/Haul Mode under Towing a Trailer for more information.
Grade Braking
Grade Braking assists when driving on a downhill grade. It maintains vehicle 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 vehicle 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 reduce vehicle 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.
