Grade Braking (Six Speed Automatic
Transmission)
The Grade Braking shift modes can be activated by
pressing the tow/haul button on the dash. 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 (Six Speed Automatic
Transmission) on page 3-27 or Automatic Transmission
Operation (Four Speed Automatic Transmission) on
page 3-32 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 Towing a Trailer on page 5-30 for more
