Automatic Transmission Operation
The shift lever is located on the center console between
the front seats.
There are several different
positions for the shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.
{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.
CAUTION: (Continued)
CAUTION: (Continued)
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 2-36.
If you are pulling a trailer, seeTowing a Trailer
on page 4-41.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes rst and then press the
shift lever button before you can shift from PARK (P)
when the ignition key is in ON/RUN. If you cannot
shift out of PARK (P), ease pressure on the shift lever
and push the shift lever all the way into PARK (P) as
you maintain brake application. Then press the shift
lever button and move the shift lever into another gear.
SeeShifting Out of PARK (P) on page 2-38.

When Tow/Haul is activated the Tow/Haul symbol
will illuminate on the instrument panel cluster.
SeeTow/Haul ModeunderTowing a Trailer on
page 4-41for more information.
Grade Braking
Grade Braking assists when driving on a downhill
grade. It maintains the vehicle’s speed by automatically
implementing a shift schedule that uses the engine
and the transmission to slow the vehicle. This reduces
wear on the brakes system and increases control of the
vehicle. The system constantly monitors the vehicle’s
speed, acceleration, throttle position, and whether the
brake pedal is being pressed, and determines when
to keep the current vehicle speed or to slow down.
The system will then automatically command downshifts
that reduces the vehicles speed, until the brake pedal is
no longer being pressed. This indicates the desired
vehicle speed has been reached.The tow/haul mode and grade braking shift modes can
be activated by pressing the button on the instrument
panel console. While in the DSC mode, grade braking is
deactivated, allowing the driver to select a gear.
SeeAutomatic Transmission Operation on page 2-30.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
2-34
If the ignition is on, the brake system warning light
on the instrument panel cluster should come on.
If it does not, you need to have your vehicle serviced.
SeeBrake System Warning Light on page 3-38for
more information.
To release the parking brake, pull the release lever
located to the left of the steering wheel on the
instrument panel.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.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill,
seeTowing a Trailer on page 4-41for more information.
