{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your 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 your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into PARK (P) on
page 2-33. If you are pulling a trailer, see
Towing a Trailer on page 4-28.
The positions for the shift lever are:
PARK (P): This position locks the vehicle’s front
wheels. It is the best position to use when the engine is
started because the vehicle cannot move easily.Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an electronic shift
lock release system. You must fully apply the regular
brakes before shifting from PARK (P) when the ignition
is in ON/RUN. If you cannot shift out of PARK (P),
ease pressure on the shift lever by pushing it all the way
into PARK (P) as you maintain brake application.
Then move the shift lever into another gear. SeeShifting
Out of PARK (P) on page 2-35
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
REVERSE (R): Use this gear to back up.
To rock the vehicle back and forth in order to get it out
of snow, ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-20.
NEUTRAL (N):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when the vehicle is being towed.
2-30

Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transmission. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of SECOND (2).
SECOND (2): This position reduces vehicle speed even
more than THIRD (3) without using your brakes. You can
use SECOND (2) on hills. It can help control your speed
as you go down steep mountain roads, but then you
would also want to use your brakes off and on.
FIRST (1): This position reduces vehicle speed even
more than SECOND (2) without using your brakes. You
can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst 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 your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Parking Brake
To set the parking brake,
hold the regular brake
pedal down with your right
foot. Push down the
parking brake pedal with
your left foot.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal with your left foot. While you lift your
left foot, the parking brake pedal will follow it to the
released position.
A warning chime will sound and PARKING BRAKE ON
will display in the DIC if the parking brake is set, the
ignition is on, and the vehicle speed is greater than
5 mph (8km/h). For more information seeBrake System
Warning Light on page 3-37andDIC Warnings and
Messages on page 3-58.
2-32

Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and parking on any hill, see
Towing a Trailer on page 4-28. That section shows what
to do rst to keep the trailer from moving.
Shifting Into PARK (P)

2-34

Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of PARK (P). This is called torque lock. To
prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the driver’s
seat. To nd out how, seeShifting Into PARK (P) on
page 2-33.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever is
in PARK (P)
Prevent movement of the shift lever out of PARK
(P), unless the ignition is in ON/RUN and the
regular brake pedal is applied.
The shift lock is always functional except in the case of
a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-50.
