WARNING!(Continued)
•When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the key fob from the vehicle and lock the
vehicle.
• 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.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
• Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
(Continued)
CAUTION! (Continued)
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. 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 switch is in
the OFF position.

STARTING AND OPERATING 469

Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the gear selector in
PARK unless the brakes are applied. To shift the trans-
mission 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.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. Press the “ECO” switch in the center stack of the
instrument panel to activate or disable ECO mode. An
amber light indicates when ECO mode is engaged.When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•
The transmission will upshift sooner and downshift
later.Fuel Economy Mode Switch
470 STARTING AND OPERATING

•The transmission will launch (from a stop) in second
gear.
• The torque converter clutch may engage at lower
engine speeds and remain on longer.
• The engine idle speed will be lower.
• The overall driving performance will be more conser-
vative.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
NOTE: ECO mode is only available in AUTO mode.
Active Noise Cancellation
Your vehicle is equipped with an Active Noise Cancella-
tion System, this system is designed to address the
change in exhaust noise whenever the vehicle is operat-
ing in Fuel Economy Mode (ECO) or 4 cylinder mode. This system relies on four microphones embedded in the
headliner to detect the exhaust drone and prompt an
onboard frequency generator to create counteracting
sound waves through the audio system’s speakers and
sub-woofer. This helps keep the vehicle quiet at highway
speeds.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
besides the gear selector bezel and in the Driver Infor-
mation Display (DID). To select a gear range, press the
lock button on the gear selector and move the lever
rearward or forward. To shift the transmission out of
PARK, the engine must be running and the brake pedal
must be pressed. You must also press the brake pedal to
shift from NEUTRAL into DRIVE or REVERSE when the
vehicle is stopped or moving at low speeds (refer to
“Brake/Transmission Shift Interlock System” in this sec-
tion). Select the DRIVE range for normal driving.5
STARTING AND OPERATING 471

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).
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, RE-
VERSE, NEUTRAL, DRIVE and MANUAL (AutoStick)
shift positions. Manual shifts can be made using the
AutoStick shift control (refer to “AutoStick” in this
section for further information). Toggling the gear selec-
tor forward (-) or rearward (+) while in the MANUAL
(AutoStick) position (beside the DRIVE position), ortapping the shift paddles (+/-), will manually select the
transmission gear, and will display the current gear in the
instrument cluster.
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
transmission 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, RE-
VERSE, and NEUTRAL.
472 STARTING AND OPERATING

Gear Ranges
DO NOT race the engine 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 leaving the
vehicle in this range.
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. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

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 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
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission
is in PARK before leaving 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 re-
verse. You could lose control of the vehicle and hit

WARNING! (Continued)
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 apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the Key Fob.
When the ignition is in the OFF mode, the trans-
mission 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.

474 STARTING AND OPERATING

WARNING!(Continued)
•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 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.
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 gear selector out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the gear selector could
result.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
• When shifting into PARK, press the lock button on the
gear selector and push the lever 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 position (P).
5
STARTING AND OPERATING 475

•With brake pedal released, verify that the gear selector
will not move out of PARK.
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
transmission 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, RE-
VERSE, and NEUTRAL.
REVERSE (R)
This range is for moving the vehicle backward. 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. Apply the parking brake and shift the transmission into PARK if you must
leave the vehicle.
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. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
476 STARTING AND OPERATING

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing a heavy trailer), select TOW mode (refer to
“Selec-Track” in “Starting And Operating”) or use the
AutoStick shift control (refer to “AutoStick” in this
section for further information) to select a lower gear.
Under these conditions, using TOW mode or a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of transmission
shifting (also known as AutoStick mode; refer to
“AutoStick” in this section for further information). Tog-
gling the gear selector forward (-) or rearward (+) while
in the MANUAL (AutoStick) position will manually
select the transmission gear, and will display the current
gear in the instrument cluster.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
5
STARTING AND OPERATING 477

result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be
illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle. 2. Shift the transmission into PARK, if possible. If not,
shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
