NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Ignition Park Interlock
Vehicles with push button start:
This vehicle is equipped with an Ignition
Park Interlock which requires the transmis-
sion 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 transmission in
PARK whenever the ignition is in the OFF
mode.
Vehicles with mechanical key:
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis -
sion to be in PARK before the ignition can be
turned to the OFF (key removal) position. The
key can only be removed from the ignition when the ignition is in the OFF position, and
the transmission is locked in PARK whenever
the ignition is in the OFF position.
If the vehicle's battery becomes discharged,
the key will be trapped in the ignition even
when the gear selector is in PARK. Recharge
the battery to allow key removal.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans
-
mission 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 ignition must
be in the ON/RUN mode (whether the engine
is running or not), 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.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is
displayed both beside the gear selector and
in the instrument cluster. To select a gear
range, push the lock button on the gear
selector and move the selector rearward or
forward. You must also press the brake pedal
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the park 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 a vehicle equipped with push button
start) in the ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
CAUTION!
Damage to the transmission may occur if
the following precautions are not observed:
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.
WARNING! (Continued)
Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.

to shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or
moving at low speeds). Select the DRIVE
range for normal driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE
while driving forward), the position indicator
will blink continuously until the selector is
returned to the proper position, or the
requested shift can be completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts
on a new vehicle may be somewhat abrupt.
This is a normal condition, and precision
shifts will develop within a few hundred
miles (kilometers).
The nine-speed transmission has been devel-
oped to meet the needs of current and future
FWD/AWD vehicles. Software and calibration
is refined to optimize the customer’s driving
experience and fuel economy. By design,
some vehicle and driveline combinations
utilize 9th gear only in very specific driving
situations and conditions. Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting
between these gears.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
AutoStick (+/-) shift positions. Manual shifts
can be made using the AutoStick shift
control. Moving the gear selector into the
AutoStick (+/-) position (beside the DRIVE
position) activates AutoStick mode,
providing manual shift control and displaying
the current gear in the instrument cluster (as
1, 2, 3, etc.). Toggling the gear selector
forward (-) or rearward (+) while in the Auto
-
Stick position will manually select the trans -
mission gear. Refer to "AutoStick" in this
section for further information.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward) it is probably in the
AutoStick (+/-) position (beside the DRIVE
position). In AutoStick mode, the transmis -
sion gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to
the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL. Gear Selector
Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into
another gear range.
NOTE:
After selecting any gear range, wait a
moment to allow the selected gear to engage
before accelerating. This is especially
important when the engine is cold.
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.

(Continued)
When parking on a level surface, you may
shift the transmission into PARK first, and
then apply the parking brake.
When parking on a hill, apply the parking
brake before shifting the transmission to
PARK, otherwise the load on the transmis -
sion locking mechanism may make it diffi -
cult to move the gear selector out of 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.
When exiting the vehicle, always:
1. Apply the parking brake.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Remove the key fob from the vehicle.
NOTE:
Block the wheels with a wedge or a stone if
the vehicle is parked on a steep slope.
WARNING!
Never use the PARK position as a substi -
tute for the park brake. Always apply the
park brake fully when exiting the vehicle
to guard against vehicle movement 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 gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
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.
The vehicle may not engage a newly
selected gear when shifting between
PARK, REVERSE, or DRIVE if the
vehicle is moving while shifting.
WARNING! (Continued)
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 park
brake, shift the transmission into PARK,
turn the engine OFF, and remove the key
fob. When the ignition is in the LOCK/
OFF (key removal) position (or, with push
button start, when the ignition is in the
OFF mode), the transmission is locked in
PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always make
sure the ignition 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 unat -
tended is dangerous for a number of
reasons. A child or others could be seri -
ously or fatally injured. Children should
be warned not to touch the park brake,
brake pedal or the transmission gear
selector.
WARNING! (Continued)

The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
When shifting into PARK, push the lock
button on the gear selector, and firmly
move the selector all the way forward until
it stops and is fully seated.
Look at the transmission gear position
display and verify that it indicates the
PARK (P) position.
With brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle back-
ward. Shift into REVERSE only after the
vehicle has come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing
for prolonged periods with the engine
running. The engine may be started in this
range. Apply the park brake and shift the
transmission into PARK if you must exit the
vehicle.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears. The
DRIVE position provides optimum driving
characteristics under all normal operating
conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick
shift control to select a lower gear (refer to
"AutoStick" in this section for further infor -
mation). Under these conditions, using a
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 a vehicle equipped with push button
start) in the ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must turn the
ignition to the ON/RUN mode, and also
press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting
from PARK or NEUTRAL into another
gear range, as this can damage the drive-
train.
WARNING! (Continued)
WARNING!
Do not coast in NEUTRAL and never turn
off the ignition to coast down a hill. These
are unsafe practices that limit your
response to changing traffic or road
conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for
any other reason with the transmission in
NEUTRAL can cause severe transmission
damage.
