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 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 (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 operates in third gear only.
Used for improved traction on slippery roads. Selecting 3 (Third)
provides engine braking.
2 (Second)
Transmission operates in 2nd gear only.
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
1 (First)
• Transmission operates in 1st gear only.
• Provides maximum engine braking.
• Allows upshifts by moving gearshift lever.
• Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
• Allowed in D (Drive) only.
• Depress the accelerator to the floor.
• Allows transmission to select an appropriate gear.
