STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust
both inside and outside mirrors, and fasten your seat
belts.
WARNING!
•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. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the transmission gear selec-
tor.
• Do not leave the key fob in or near the vehicle (or
in a location accessible to children). A child could
operate power windows, other controls, or move
the vehicle.
Automatic Transmission
The gear selector must be in the PARK or NEUTRAL
position before you can start the engine. Depress the
brake pedal before shifting to any driving gear. NOTE:
You must press the brake pedal before shifting
out of PARK.
Normal Starting
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Turn the ignition switch to the AVV/ACC (START)
position and release it when the engine starts. If the
engine fails to start within 10 seconds, turn the ignition
switch to the STOP (OFF/LOCK) position, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
Cold Weather Operation
To prevent possible engine damage while starting at
low temperatures, this vehicle will inhibit engine crank-
ing when the ambient temperature is less than –22°F
(–30°C) and the oil temperature sensor reading indi-
cates an engine block heater has not been used. An
externally powered electric engine block heater is avail-
able as a factory installed option.
The message “plug in engine heater” will be displayed
in the instrument cluster when the ambient temperature
is below 5°F (–15°C) at the time the engine is shut off as
218 STARTING AND OPERATING

a reminder to avoid possible crank delays at the next
cold start.
CAUTION!
Use of the recommended SAE 5W-40 Synthetic oil
and adhering to the prescribed oil change intervals
is important to prevent engine damage and ensure
satisfactory starting in cold conditions.
Extended Park Starting
NOTE:Extended Park condition occurs when the ve-
hicle has not been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the
crank cycle.
2. Cycle the ignition in the START position and release it when the engine starts.
3. If the engine fails to start within 10 to 15 seconds, cycle the ignition to the STOP (OFF/LOCK) position,
wait five seconds to allow the starter to cool, then
repeat the Extended Park Starting procedure. 4. If the engine fails to start after eight attempts, allow
the starter to cool for at least 10 minutes, then repeat
the procedure.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
To prevent damage to the starter, do not continu-
ously crank the engine for more than 15 seconds at
a time. Wait 10 to 15 seconds before trying again.

STARTING AND OPERATING 219

After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool
the turbocharger after the engine is shut off. Depending
on the type of driving and the amount of cargo, the pump
will run for up to 10 minutes after the engine has been
shut off to circulate coolant through the turbocharger.
Although the pump is rubber-mounted for quiet opera-
tion, it is normal to hear it running during this time.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the fol-
lowing 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, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
(Continued)
CAUTION! (Continued)
•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.
WARNING!
• 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 apply
the parking brake, shift the transmission into
PARK, turn the engine OFF, and remove the

WARNING!(Continued)
ignition key. Once the key is removed, the trans-
mission is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always remove the
ignition key 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 ignition key in or near the
vehicle (or in a location accessible to children). A
child could operate power windows, other con-
trols, or move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park
Interlock which requires the transmission to be in PARK
before the ignition can be turned to the LOCK/OFF
(key removal) position. The key can only be removed from the ignition when the ignition is in the LOCK/OFF
position, and once removed, the transmission is locked
in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission
Shift Interlock System (BTSI) that holds the transmis-
sion gear selector in PARK unless the brakes are ap-
plied. To shift the transmission out of PARK, the igni-
tion must be turned to the ON/RUN mode (engine
running or not), and the brake pedal (and the lock
button on the gear selector) must be pressed.
Six-Speed Automatic Transmission
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear
range. You must press the brake pedal and push the
lock button on the gear selector to move the gear
selector out of PARK (Refer to “Brake/Transmission
Shift Interlock System” in this section). To drive, push
the lock button on the front of the gear selector and
move the gear selector from PARK or NEUTRAL to the
DRIVE position.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
5
STARTING AND OPERATING 221

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 has PARK, REVERSE,
NEUTRAL, DRIVE, and AutoStick (+/-) shift positions.
Manual shifts can be made using the AutoStick shift
control (refer to “AutoStick” in this section for furtherinformation). Moving the gear selector into the
AutoStick (+/-) position (beside the DRIVE position)
activates AutoStick mode, providing manual shift con-
trol and displaying the current gear in the instrument
cluster (as 1, 2, 3, etc). Toggling the gear selector
forward (-) or rearward (+) while in the Autostick
position will manually select the transmission gear.
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,
REVERSE, and NEUTRAL.
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.
Transmission Gear Selector
222 STARTING AND OPERATING

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 park-
ing brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load
on the transmission locking mechanism may make it
difficult 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:
•Apply the parking brake.
• Shift the transmission into PARK.
• Turn the engine OFF.
• Remove the ignition key.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.
• 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 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
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 apply
the parking brake, shift the transmission into

WARNING!(Continued)
PARK, turn the engine OFF, and remove the
ignition key. Once the key is removed, the trans-
mission is locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always remove the
ignition key 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 ignition key in or near the
vehicle (or in a location accessible to children). A
child could operate power windows, other con-
trols, or move the vehicle.
CAUTION!
•Before moving the transmission gear selector out
of PARK, you must turn the ignition to the
(Continued)
CAUTION! (Continued)
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 drivetrain.
The following indicators should be used to ensure that
you have engaged the transmission into the PARK
position:
• When shifting into PARK, push the lock button on
the gear selector and firmly move the gear 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 position (P).
• With brake pedal released, verify that the gear selec-
tor 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.
224 STARTING AND OPERATING

NEUTRAL (N)
Use this range when the vehicle is standing for pro-
longed periods with the engine running. The engine
may be started in this range. 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 traf-
fic 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.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 con-
ditions, in hilly terrain, or traveling into strong head
winds), use the AutoStick shift control (refer to
AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a
lower gear will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will expand the
range of torque converter clutch engagement. This is
done to prevent transmission damage due to overheat-
ing.
5
STARTING AND OPERATING 225

During cold temperatures, transmission operation may
be modified depending on engine coolant temperature.
Normal operation will resume once the engine tempera-
ture has risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual condi-
tions occur.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that
could result in transmission damage, Transmission
Limp Home Mode is activated. In this mode, the
transmission remains in third gear regardless of which
forward gear is selected. PARK, REVERSE, and NEU-
TRAL will continue to operate. The Malfunction Indi-
cator Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an authorized
dealer for service without damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing
the following steps:
1. Stop the vehicle.2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to nor-
mal operation.
NOTE: Even if the transmission can be reset, we rec-
ommend 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.
AUTOSTICK
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
226 STARTING AND OPERATING

can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driv-
ing, and many other situations.
Operation
When the gear selector is in the AutoStick position
(beside the Drive position), it can be moved forward
and rearward. This allows the driver to manually select
the transmission gear being used. Moving the gear
selector forward (-) triggers a downshift, and rearward
(+) an upshift. The current gear is displayed in the
instrument cluster.
NOTE:In AutoStick mode, the transmission will only
shift up or down when the driver moves the gear
selector rearward (+) or forward (-), except as described
below.
• The transmission will automatically upshift when
necessary to prevent engine over-speed.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear. •
The transmission will automatically downshift to
first gear when coming to a stop. After a stop, the
driver should manually upshift (+) the transmission
as the vehicle is accelerated.
• You can start out (from a stop) in first, second, or
third gear. Starting out in second or third gear can be
helpful in snow or icy conditions. To select second or
third gear after the vehicle is brought to a stop, tap
the gear selector rearward (+) once or twice.
• If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Avoid using speed control when AutoStick is en-
gaged because the transmission will not shift auto-
matically.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
• The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, return the gear selector
to the DRIVE position. You can shift in or out of the
