D (Drive with Overdrive) with Tow/Haul On
The Tow/Haul feature improves
transmission operation when towing
a trailer or a heavy load. All
transmission gear ranges are
available when using Tow/Haul.
To activate Tow/Haul, press the
button on the side of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/Haul delays upshifts to reduce frequency of transmission shifting.
Tow/Haul also provides engine braking in all forward gears when the
transmission is in the D (Drive with Overdrive) position; this engine
braking will slow the vehicle and assist the driver in controlling the
vehicle when descending a grade. Depending on driving conditions and
load conditions, the transmission may downshift, slow the vehicle and
control the vehicle speed when descending a hill, without the accelerator
pedal being pressed. The amount of downshift braking provided will vary
based upon the amount the brake pedal is depressed.
To deactivate the Tow/Haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will automatically
return to normal D (Drive with Overdrive) mode (Tow/Haul OFF).
