WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on 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 when your foot is
firmly on the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the ignition switch to the LOCK posi-
tion. The key fob can only be removed from the ignition
switch when the ignition switch is in the LOCK position
and once removed the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to either the
ON or START position (engine running or not) and the
brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the ignition switch in the ON position and the brake
pedal pressed. To operate the shift lock manual override,
perform the following steps:
1. Turn the ignition switch to the ON position, but do not
start the engine.
2. Firmly set the parking brake.5
STARTING AND OPERATING 241

3. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel.
4. Press and maintain firm pressure on the brake pedal.
5. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.6. Move the shift lever into the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
Have your vehicle inspected by your local authorized
dealer, if the shift lock manual override has been used.
Five–Speed Automatic Transmission
The electronically controlled transmission provides a
precise shift schedule. 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.
Interlock Manual Override
242 STARTING AND OPERATING

NOTE:The Electronic Stability Program (ESP) and
Traction Control (if equipped) should be turned OFF
before attempting to rock the vehicle. Refer to “Electronic
Brake Control System” in “Starting and Operating” for
further information.
The least amount of accelerator pedal pressure to main-
tain the rocking motion without spinning the wheels or
racing the engine is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
the vehicle, may lead to transmission overheating and
failure. Allow the engine to idle with the shift lever in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.CAUTION!
When “rocking” a stuck vehicle by moving between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
AUTOSTICK
AutoStick is a driver-interactive transmission that offers
manual gear shifting capability to provide the driver
with more control. AutoStick allows the driver to in-
crease engine braking ability, control upshift and down-
shift points, and enhance the driving experience. This
system can also provide the driver with more control
during passing, city driving, mountain driving, trailer
towing, and many other situations.

STARTING AND OPERATING 245

Operation
By placing the shift lever in the DRIVE position, the shift
lever can be moved from side to side. This allows the
driver to engage the AutoStickmode. Moving the shift
lever to the right (+) or the left (-) will engage the
AutoStick mode. In normal driving mode (Boxed “D”
displayed in the PRNDL), moving the shift lever to the
right (+) will engage the AutoStick mode putting the
transmission in the currently engaged gear. Moving the
shift lever to the Left (-) will engage the AutoStick mode
and downshift the transmission one gear. For example, if
the transmission is in Drive mode (a boxed Dis
displayed in the cluster) and is operating in third gear,
tapping the shift lever to the right (+) will engage
AutoStick mode (while remaining in third gear) and a
boxed 3will be displayed in the cluster. Tapping the
shift lever to the left (-) would also engage AutoStick 
mode, but would force a downshift to second gear, and display a boxed
2in the cluster. Once AutoStick mode
is engaged, a move to the right (+) or left (-) will trigger
a upshift (+) or trigger a downshift (-).
NOTE: In the AutoStick mode, the transmission will
shift up and down when left or right (D-/D+) is manu-
ally selected by the driver.
The transmission will not allow a downshift if the
downshift would result in an engine overspeed condi-
tion. The transmission will always allow a upshift from
first to second gear, however 2nd - 3rd, 3rd - 4th, and 4th
– 5th upshifts will not be allowed if the vehicle speed is
too low to maintain operation in the selected gear. The
transmission will automatically downshift as the vehicle
slows to a stop (to prevent engine lugging) and will
display the current gear. After a stop, the driver should
manually upshift (D+) the transmission as the vehicle is
accelerated.
246 STARTING AND OPERATING

When in the AutoStickmode, as the engine RPM nears
the engine maximum speed, an “UPSHIFT” message will
appear in the Electronic Vehicle Information Center
(EVIC) portion of your instrument cluster. This message
appears in order to alert the driver that the engine speed
is approaching it’s maximum value and a upshift to the
next gear is required. In the event that the driver does not
upshift, the engine control system will automatically do it
for the driver. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
Shifting into or out of the AutoStick mode can be done
at any time without taking your foot off the accelerator
pedal. When the driver wishes to engage AutoStick ,
simply move the shift lever to the left or right (D-/D+)
position while in DRIVE. Hold the shift lever to the right for at least one second to
disengage AutoStick. The transmission will now oper-
ate automatically; shifting between the five available
gears.
General Information
•
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop. Tapping the shift lever to
the D+ position (at a stop) will allow starting in second
gear. After starting, the driver should continue to
manually upshift (D+) as the vehicle is accelerated.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when AutoStick
is en-
gaged.
