298 STARTING AND OPERATING
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave the transmission in
PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park brake,
firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.Parking Brake Release When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the transmission is
placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake before
placing the gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in the
vehicle.

AUTOMATIC TRANSMISSION
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Leaving unattended children in
a vehicle is dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before driving; failure to do so can lead to brake failure and a
collision.
• Always fully apply the parking brake when leaving your vehicle or it may roll and cause damage or injury.
Also, be certain to leave the transmission in PARK.
Failure to do so may cause the vehicle to roll and cause
damage or injury.CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment and possible injury or damage.
• Your vehicle could move and injure you and others if it is not in PARK. Check by trying to move the transmis -
sion gear selector out of PARK with the brake pedal
released. Make sure the transmission is in PARK before
exiting the vehicle.

(Continued)
• The transmission may not engage PARK if the vehicleis moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is
not firmly pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You could lose
control of the vehicle and hit someone or something.
Only shift into gear when the engine is idling normally
and your foot is firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure those in or near the vehicle. As with all vehicles, you should
never exit a vehicle while the engine is running. Before
exiting a vehicle, always come to a complete stop, then
apply the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the ignition is
in the OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
WARNING! (Continued)
• When exiting the vehicle, always make sure the igni -
tion is in the OFF mode, remove the key fob from the
vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the transmission gear
selector.
• Do not leave the key fob in or near the vehicle (or in a location accessible to children), and do not leave the
ignition in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
WARNING! (Continued)

STARTING AND OPERATING 301
NOTE:
You must press and hold the brake pedal while shifting out
of PARK.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the driver
avoid inadvertently leaving the vehicle without placing the
transmission in PARK. This system also locks the transmis-
sion in PARK whenever the ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK when the ignition
is in the ACC mode (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition is
OFF (not in ACC mode) before exiting the vehicle.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
Eight-Speed Automatic Transmission
The transmission is controlled using a rotary electronic gear
selector located on the instrument panel. The transmission
gear range (PRND) is displayed both above the gear selector
and in the instrument cluster. To select a gear range, simply
rotate the gear selector. You must press the brake pedal to
shift the transmission out of PARK (or NEUTRAL, when the
vehicle is stopped or moving at low speeds). To shift past
multiple gear ranges at once (such as PARK to DRIVE),
simply rotate the gear selector to the appropriate detent.
Select the DRIVE range for normal driving.
CAUTION!
• Shift into or out of PARK or REVERSE only after the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL, or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is firmly pressing the brake pedal.

PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range. Never
attempt to use PARK while the vehicle is in motion. Apply
the parking brake when exiting the vehicle in this range.
When parking on a level surface, you may shift the transmis-
sion into PARK first, and then apply the parking brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precaution,
turn the front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade.
NOTE:
On four-wheel drive vehicles be sure that the transfer case is
in a drive position.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the key fob.WARNING!

304 STARTING AND OPERATING
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK posi-
tion:
• Look at the transmission gear position display and verify that it indicates the PARK position (P), and is not blinking.
• With brake pedal released, verify that the gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete stop.
• Unintended movement of a vehicle could injure those
in or near the vehicle. As with all vehicles, you should
never exit a vehicle while the engine is running. Before
exiting a vehicle, always come to a complete stop, then
apply the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the ignition is
in the OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When exiting the vehicle, always make sure the igni -
tion is in the OFF mode, remove the key fob from the
vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the transmission gear
selector.
• Do not leave the key fob in or near the vehicle (or in a location accessible to children), and do not leave the
ignition in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
WARNING! (Continued)CAUTION!
• DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage
the drivetrain.
• Before moving the transmission gear selector out of PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.

314 STARTING AND OPERATING
Manually Shifted Transfer Case — If Equipped
The transfer case provides four mode positions:
• Two-Wheel Drive High Range (2H)
• Four-Wheel Drive Lock High Range (4H)
• Neutral (N)
• Four-Wheel Drive Low Range (4L)
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2H
Two-Wheel Drive High Range — This range is for normal
street and highway driving on dry, hard surfaced roads.
4H
Four-Wheel Drive Lock High Range — This range locks the
front and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction for
loose, slippery road surfaces only.
NEUTRAL (N)
Neutral — This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat towingbehind another vehicle. Refer to “Recreational Towing” in
“Starting And Operating” for further information.
4L
Four-Wheel Drive Low Range — This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
This transfer case is intended to be driven in the 2H position
for normal street and highway conditions such as dry, hard
surfaced roads.
When additional traction is required, the 4H and 4L posi -
tions can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at the
same speed. This is accomplished by simply moving the gear
selector to the desired positions once the appropriate speed
and gear requirements are met, refer to “Shifting Procedure
– Manually Shifted Transfer Case” in this section for further
information.
The 4H and 4L positions are intended for loose, slippery road
surfaces only. Driving in the 4H and 4L positions on dry,
hard surfaced roads may cause increased tire wear and
damage to the driveline components.

STARTING AND OPERATING 315
The “Transfer Case Position Indicator Light” in the instru-
ment cluster will alert the driver that the vehicle is in
four-wheel drive and that the front and rear driveshafts are
locked together. This light will illuminate when the transfer
case is shifted into either the 4H or 4L position. There is no
light for the 2H or NEUTRAL positions on some models.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H positions at a
given road speed. Take care not to overspeed the engine and
do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference will adversely affect shifting and can cause
damage to the drivetrain.
NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning, as this can cause damage to driveline
components.
Because four-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds. Do
not go faster than road conditions permit.NOTE:
Delayed shifts out of four-wheel drive may be experienced
due to uneven tire wear, low or uneven tire pressures, exces
-
sive vehicle loading, or cold temperatures.
Two-Wheel Drive High Range (2H)
Rear-Wheel Drive High Range — This range is for normal
street and highway driving on dry hard surfaced roads.
Four-Wheel Drive High Range (4H)
Four-Wheel Drive High Range — This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction for
loose, slippery road surfaces only.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from the
powertrain and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle.
