Tow/Haul Mode

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 towing or hauling heavy loads.

The selector button is located on the end of the shift
lever. Turn the tow/haul on and off by pressing the
button. When the tow/haul is on, a light on the
instrument panel cluster will come on.

See Tow/Haul Mode Light on page 4‑48 for more
information.

Also see Tow Haul Mode under Towing a Trailer on
page 5‑55 for more information.
