Tow/Haul Mode
4-Speed Automatic Transmission
6-Speed Automatic Transmission
Vehicles with an automatic transmission have 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 driving down steep hills or Mountain grades, towing, or hauling heavy loads.
The selector button is located on the end of the shift lever. Turn the Tow/ Haul Mode on and off by pressing the button. When the Tow/Haul Mode is enabled, a light on the instrument panel cluster will come on.
See Tow/Haul Mode Light on page 5‑29 and Hill and Mountain Roads on page 9‑13 for more information.
Also see “Tow/Haul Mode” under Towing Equipment on page 9‑100 for more information.
