braking can cause the rear wheels to slide
and your vehicle to swing around with the
possible loss of vehicle control.
E161509
To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator
light illuminates in the instrument cluster.
The tow/haul feature:
Delays upshifts to reduce the frequency
of transmission shifting.
Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided will vary
based upon the amount you press the
brake pedal.
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.
Note: If your vehicle is equipped with the
Adaptive Steering System, enabling the
tow/haul feature will adjust the steering
response. In tow/haul mode the Adaptive
Steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds
while maintaining the ease of parking and
maneuverability at low speeds. See
Steering (page 256).
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever when
tow/haul is active. The TOW HAUL light
deactivates. Tow/haul also deactivates
when you power down your vehicle.
