Your vehicle has a tow/haul mode. The tow/haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when towing or hauling heavy loads.
Press the button located on the end of the shift lever to turn the tow/haul on or off. When the tow/haul is on, a light on the instrument panel cluster will come on.
See Tow/Haul Mode Light for more information.
Also see "Tow Haul Mode" under Towing a Trailer for more information.
The tow/haul mode works with the Autoride® feature, if the vehicle has this, to enhance the ride when trailering or with a loaded vehicle. See Autoride® .
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 end of the shift control stalk. While in the DSC mode, grade braking is deactivated, allowing the driver to select a gear.
