Driving and Operating
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.
Turn the Tow/Haul Mode on and off
by pressing the button, located to
the right of the steering wheel on
the instrument panel. When tow/
haul is on, a light on the instrument
panel cluster will come on.
See Tow/Haul Mode Light on
page 5‑24 for more information.
Also see “Tow Haul Mode” under
Towing Equipment on page 9‑54 for
more information.
Grade Braking (Six Speed
Automatic Transmission)
The Grade Braking shift modes
can be activated by pressing
the TOW/HAUL button on the
instrument panel. While in Range
Selection Mode, Grade Braking is
deactivated allowing the driver to
select a desired range of gears.
Grade Braking is only active while
the Tow/Haul Mode is selected and
you are not in the Range Selection
Mode. See “Tow/Haul Mode” listed
previously and Manual Mode on
page 9‑31 for more information on
the Range Selection Mode. Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades by automatically
shifting to lower gears when the
driver desires to slow the vehicle by
applying the brake. This reduces
wear on the braking system and
increases control of the vehicle.
Also see Trailer Towing on
page 9‑50 for more information.
Cruise Grade Braking
(Six Speed Automatic
Transmission)
Cruise Grade Braking operates only
while Cruise Control is engaged
in Tow/Haul Mode. Cruise Grade
Braking assists in maintaining
desired vehicle speeds when driving
on downhill grades in cruise control
by automatically shifting to lower
gears when the cruise set speed is
exceeded.
While in the Range Selection
Mode, Cruise Grade Braking is not
available.
