Automatic Transmission Operation
(Four Speed Automatic
Transmission)
There are several different positions for your shift lever.
P (Park):This position locks your rear wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 3-37. If you are pulling a trailer, see
Towing a Trailer on page 5-30.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must first
press the brake pedal before you can shift from P (Park)
with the ignition in ON/RUN.
If you cannot shift out of P (Park), ease pressure on the
shift lever and push the shift lever all the way into
P (Park) as you maintain brake application. Then move
the shift lever into another gear. SeeShifting Out of
Park on page 3-38.
3-32

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice or sand without damaging the transmission, see
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5-18.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It
provides the best fuel economy. If you need more
power for passing, and you are:
•Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-10.
3 (Third):This position is also used for normal driving.
However it reduces vehicle speed more than D (Drive)
without using the brakes. You might choose 3 (Third)
instead of D (Drive) when driving on hilly, winding roads,
when towing a trailer, so there is less shifting between
gears and when going down a steep hill.
You should use 3 (Third) (or a lower gear as needed)
when towing a trailer to minimize heat build-up and
extend the life of the transmission.
3-33

2 (Second):This position reduces vehicle speed even
more than 3 (Third) without using the brakes. You
can use 2 (Second) on hills. It can help control vehicle
speed as you go down steep mountain roads, but
then you would also want to use the brakes off and on.
You may use this feature for reducing torque to the
rear wheels when you are trying to start the vehicle from
a stop on slippery road surfaces.
1 (First):This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud. If
the shift lever is put in 1 (First) while the vehicle
is moving forward, the transmission will not shift into
first gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on a
hill, use the brakes to hold the vehicle in place.Tow/Haul Mode
Vehicles with an automatic transmission have a tow/haul
mode. The tow/haul mode adjusts the transmission
shift pattern to reduce shift cycling, providing increased
performance, vehicle control, and transmission
cooling when towing or hauling heavy loads.
3-34

Turn the tow/haul mode on and off by pressing the
button, located to the right of the steering wheel on the
instrument panel. When tow/haul is on, a light on
the instrument panel cluster will come on.
SeeTow/Haul Mode Light on page 4-35for more
information.
Also see “Tow Haul Mode” underTowing a Trailer on
page 5-30for more information.
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 3-27orAutomatic Transmission
Operation (Four Speed Automatic Transmission) on
page 3-32for 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 seeTowing a Trailer on page 5-30for more
information.

Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has StabiliTrak
®, and the system begins to
limit wheel spin, cruise control will automatically
disengage. SeeStabiliTrak
®System on page 5-5. When
road conditions allow the cruise control to be safely
used again, it can be turned back on.
