Tow/Haul Mode
The 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 on page 3-46 for more
information.
Also see “Tow Haul Mode” under Towing a Trailer on
page 5-44 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
®
on page 5-44.
Grade Braking
The Grade Braking shift modes can be activated by
pressing the button on the end of the shift control lever.
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 Automatic
Transmission Operation on page 2-29 for more
information on the Range Selection Mode. Grade Braking
assists in maintaining desired vehicle speeds when
driving on downhill grades by automatically implementing
a shift schedule that utilizes the engine and transmission
to slow the vehicle. This reduces wear on the braking
system and increases control of the vehicle. Grade
Braking monitors vehicle speed, acceleration, engine
torque and brake pedal usage. Using this information, it
detects when the vehicle is on a downhill grade and the
driver desires to slow the vehicle by pressing the brake.
