D (Overdrive) with tow/haul on
E161510
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.
E161509
To activate tow/haul, press the
button on the end 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 (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
pressed.
Grade braking downshifts occur
automatically when all three of the
following occur:
•
Positive vehicle acceleration (natural
acceleration from driving on a decline)
is sensed.
•
Nearly all pressure is released from the
accelerator pedal.
•
A minimum amount of time has expired
since the last grade braking downshift.
Grade braking downshift mode is
immediately exited if the Tow/Haul mode
is deactivated or if the accelerator pedal
is depressed beyond a minimum threshold.
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 (Overdrive) mode (tow/haul
off).
WARNING
Do not use the tow/haul feature
when driving in icy or slippery
conditions as the increased engine
braking can cause the rear wheels to slide
and the vehicle to swing around with the
possible loss of vehicle control.
3 (Third)
Transmission starts and operates in third
gear only
Used for improved traction on slippery
roads. Selecting 3 (Third) provides engine
braking.
2 (Second)
Use 2 (Second) to start-up on slippery
roads or to provide additional engine
braking on downgrades.
