AutoPark

AutoPark is a supplemental feature to assist in placing the

vehicle in PARK should the situations on the following

pages occur. It is a back up system and should not be relied

upon as the primary method by which the driver shifts the

vehicle into PARK.
The conditions under which AutoPark will engage are

outlined on the following pages.

WARNING!

• Driver inattention could lead to failure to place the

vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the instrument
cluster display and on the gear selector. If the

ⴖPⴖ

indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.

• AutoPark is a supplemental feature. It is not de-

signed to replace the need to shift your vehicle into
PARK. It is a back up system and should not be
relied upon as the primary method by which the
driver shifts the vehicle into PARK.

If the vehicle is not in PARK and the driver turns off the
engine, the vehicle may AutoPark.

AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with an 8-speed transmission
• Drivers door is ajar or in conditions where driver door is

removed an additional trigger would be if the driver is

off the seat (seat pad sensor detects driver missing).

• Vehicle is not in PARK

STARTING AND OPERATING

• Vehicle Speed is 0 mph (0 km/h)
• Ignition switched from RUN to OFF

NOTE:

For Keyless Go equipped vehicles, The engine will

turn off and the ignition switch will change to ACC mode.

After 30 minutes the ignition switches to OFF automati-

cally, unless the driver turns the ignition switch OFF.

If the vehicle is not in PARK and the driver exits the
vehicle with the engine running, the vehicle may Au-
toPark.

AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with an 8-speed transmission
• Drivers door is ajar or in conditions where driver door is

removed an aditional trigger would be if the driver is off

the seat (seat pad sensor detects driver missing).

The MESSAGE “ AutoPark Engaged Shift to P then Shift
to Gear

” will display in the instrument cluster.

NOTE:

In some cases the ParkSense graphic will be

displayed in the instrument cluster. In these cases, the

shifter must be returned to “P” to select desired gear.

If the driver shifts into PARK while moving, the vehicle
may AutoPark.

AutoPark will engage ONLY when vehicle speed is 1.2

MPH (2.0 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to P”

will be displayed in the instrument cluster if vehicle speed

is above 1.2 MPH (2.0 km/h).

WARNING!

If vehicle speed is above 1.2 MPH (2.0 km/h), the
transmission will default to NEUTRAL until the ve-
hicle speed drops below 1.2 MPH (1.9 km). A vehicle
left in the NEUTRAL position can roll. As an added
precaution, always apply the parking brake when
exiting the vehicle.

STARTING AND OPERATING

295

4WD LOW

AutoPark will be disabled when operating the vehicle in
4WD LOW.

The MESSAGE “ AutoPark Disabled” will be displayed in

the instrument cluster.

Additional customer warnings will be given when both
of these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
The MESSAGE “ AutoPark Not Engaged” will be dis-

played in the instrument cluster. A warning chime will

continue until you shift the vehicle into PARK or the

Driver’s Door is closed.

ALWAYS DO A VISUAL CHECK

that your vehicle is in

PARK by looking for the

⬙P⬙ in the instrument cluster

display and on the shifter. As an added precaution, always

apply the parking brake when exiting the vehicle.

Extreme Cold Weather (Below –22°F Or −30°C)

To ensure reliable starting at these temperatures, use of an

externally powered electric engine block heater (available

from your authorized dealer) is recommended.

If Engine Fails To Start

WARNING!

• Never pour fuel or other flammable liquid into the

throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.

• Do not attempt to push or tow your vehicle to get it

started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.

• If the vehicle has a discharged battery, booster cables

may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to “Jump
Starting Procedure” in “In Case Of Emergency” for
further information.

After Starting

The idle speed is controlled automatically, and it will

decrease as the engine warms up.

296

STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED

The engine block heater warms the engine, and permits

quicker starts in cold weather. Connect the cord to a

standard 110-115 Volt AC electrical outlet with a grounded,

three-wire extension cord.
The engine block heater must be plugged in at least one

hour to have an adequate warming effect on the engine.
The engine block heater cord is found under the hood

bundled in front of the battery tray.

WARNING!

Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt AC electri-
cal cord could cause electrocution.

ENGINE BREAK-IN RECOMMENDATIONS

A long break-in period is not required for the engine and

drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After

the initial 60 miles (100 km), speeds up to 50 or 55 mph (80

or 90 km/h) are desirable.

While cruising, brief full-throttle acceleration within the

limits of local traffic laws contributes to a good break-in.

Wide-open throttle acceleration in low gear can be detri-

mental and should be avoided.
The engine oil installed in the engine at the factory is a

high-quality energy conserving type lubricant. Oil changes

should be consistent with anticipated climate conditions

under which vehicle operations will occur. For the recom-

mended viscosity and quality grades, refer to “Dealer

Service” in “Servicing And Maintenance”.

CAUTION!

Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.

NOTE:

A new engine may consume some oil during its

first few thousand miles (kilometers) of operation. This

should be considered a normal part of the break-in and not

interpreted as a problem.

STARTING AND OPERATING

297

PARKING BRAKE

Before exiting the vehicle, make sure that the parking brake

is fully applied. Also, be certain to leave an automatic

transmission in PARK, or manual transmission in RE-

VERSE or FIRST gear.
The parking brake lever is located in the center console. To

apply the parking brake, pull the lever up as firmly as

possible. To release the parking brake, pull the lever up

slightly, push the center button, then lower the lever

completely.

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 automatic

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. For vehicles equipped

with an automatic transmission, 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.

STARTING AND OPERATING

WARNING!

• Never use the PARK position on an automatic trans-

mission 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.

• When exiting the vehicle, always remove the key fob

from the ignition and lock your 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 gear
selector.

• Do not leave the key fob in or near the vehicle, or in

a location accessible to children. A child could oper-
ate 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.

(Continued)

WARNING! (Continued)

• Always fully apply the parking brake when leaving

your vehicle or it may roll and cause damage or
injury. Also, be certain to leave an automatic trans-
mission in PARK, a manual transmission in RE-
VERSE or first gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.

CAUTION!

If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.

MANUAL TRANSMISSION — IF EQUIPPED

WARNING!

You or others could be injured if you leave the vehicle
unattended without having the parking brake fully
applied. The parking brake should always be applied
when the driver is not in the vehicle, especially on an
incline.

STARTING AND OPERATING

299

CAUTION!

Never drive with your foot resting on the clutch pedal,
or attempt to hold the vehicle on a hill with the clutch
pedal partially engaged, as this will cause abnormal
wear on the clutch.

NOTE:

During cold weather, you may experience in-

creased effort in shifting until the transmission fluid warms

up. This is normal.

To shift the gears, fully press the clutch pedal and place the

gear selector into the desired gear position (the diagram for

the engagement of the gears is displayed on the handle of

the selector).
To engage REVERSE gear from the NEUTRAL position, lift

the REVERSE ring, located below the knob and move the

gear selector all the way left and then forward.

Shifting

Fully press the clutch pedal before shifting gears. As you

release the clutch pedal, lightly press the accelerator pedal.

STARTING AND OPERATING

You should always use first gear when starting from a

standing position.

NOTE:

A certain amount of noise from the transmission is

normal. This noise can be most noticeable when the vehicle

is idling in NEUTRAL with the clutch engaged (clutch

pedal released), but it may also be heard when driving. The

noise may also be more noticeable when the transmission is

warm. This noise is normal and is not an indication of a

problem with your clutch or transmission.

Recommended Vehicle Shift Speeds

To utilize your manual transmission efficiently for both

fuel economy and performance, it should be upshifted as

listed in recommended shift speed chart. Shift at the

vehicle speeds listed for acceleration. When heavily loaded

or pulling a trailer these recommended up-shift speeds

may not apply.

Downshifting

Moving from a high gear down to a lower gear is recom-

mended to preserve brakes when driving down steep hills.

In addition, downshifting at the right time provides better

acceleration when you desire to resume speed. Downshift

progressively. Do not skip gears to avoid overspeeding the

engine and clutch.

NOTE:

Above certain speeds downshifts may be blocked

and not available.

WARNING!

Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip, and the vehicle could skid.

STARTING AND OPERATING

301

CAUTION!

• Skipping gears and downshifting into lower gears at

higher vehicle speeds can damage the engine and
clutch systems, Any attempt to shift into lower gear
with clutch pedal depressed may result damage to
the clutch system. Shifting into lower gear and
releasing the clutch may result in engine damage.

• When descending a hill, be very careful to downshift

one gear at a time to prevent overspeeding the engine
which can cause engine damage, and/or clutch dam-
age, even if the clutch pedal is pressed. If transfer
case is in low range the vehicle speeds to cause
engine and clutch damage are significantly lower.

(Continued)

CAUTION! (Continued)

• Failure to follow the maximum recommended down-

shifting speeds may cause the engine damage and/or
damage the clutch, even if the clutch pedal is
pressed.

• Descending a hill in low range with clutch pedal

depressed could result in clutch damage.

AUTOMATIC TRANSMISSION — IF EQUIPPED

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.

• 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!

• 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
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
transmission gear selector out of PARK with the

WARNING! (Continued)

brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.

• The transmission may not engage PARK if the ve-

hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion 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 re-
verse. 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.

• When exiting 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

• 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.

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 transmission 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 gear range (PRNDM) is displayed both

beside the gear selector and in the instrument cluster. To

select a gear range, press the lock button on the gear

STARTING AND OPERATING

selector and move the selector 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 mov-

ing 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 PARK while driving), the position

indicator will blink continuously until the selector is re-

turned 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).
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 MANUAL (AutoStick) shift posi-

tions. Manual shifts can be made using the AutoStick shift

control. Toggling the gear selector forward (-) or rearward

(+) while in the MANUAL (AutoStick) position (beside the

DRIVE position) will manually select the transmission

gear, and will display the current gear in the instrument

cluster. Refer to

⬙AutoStick⬙ in this section for further

information.

Gear Selector

STARTING AND OPERATING

305

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 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.
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.
When exiting the vehicle, always:
• Apply the parking brake,
• Shift the transmission into PARK,
• Turn the ignition OFF and,
• Remove the key fob from the vehicle.

NOTE:

On four-wheel drive vehicles be sure that the

transfer case is in a drive position.

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
movement and possible injury or damage.

307

CAUTION!

• 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.

• 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 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 position (P), and is not

blinking.

• 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

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.

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 exit 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.

308

STARTING AND OPERATING

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 Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.

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

(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 transmis-

sion life by reducing excessive shifting and heat buildup.

During extremely cold temperatures (-22°F [-30°C] or be-

low), transmission operation may be modified depending

on engine and transmission temperature as well as vehicle

speed. Normal operation will resume once the transmis-

sion temperature has risen to a suitable level.

MANUAL (M)

The MANUAL (M, +/-) position (beside the DRIVE posi-

tion) enables full manual control of transmission shifting

(also known as AutoStick mode; refer to “AutoStick” in this

section for further information). Toggling 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 ab-

normal conditions. If a condition is detected that could

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
