AUTOMATIC TRANSMISSION — IF EQUIPPED

You must press and hold the brake pedal while shifting out

of PARK.

GNITION

ARK

NTERLOCK

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 position. 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 position.

NOTE:

The transmission is NOT locked in PARK when the ignition

is in the ACC position (even though the engine will be off).

Ensure that the transmission is in PARK, and the ignition

is OFF (not in ACC position) before exiting the vehicle.

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 trans

mission gear selector out of PARK with the brake

pedal released. Make sure the transmission is in

PARK before exiting the vehicle.



The transmission may not engage PARK if the vehicle

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 position is prop

erly 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 reverse. You could

lose control of the vehicle and hit someone or some

thing. 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 position, the

transmission is locked in PARK, securing the vehicle

against unwanted movement.



When exiting the vehicle, always make sure the igni

tion is in the OFF position, 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 unattended 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 parking 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 the ACC or ON/RUN position. A child

could operate power windows, other controls, or

move the vehicle.

WARNING!

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.

(BTSI) S

YSTEM

This vehicle is equipped with a BTSI system 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.

UTOMATIC

RANSMISSION

The transmission gear range (PRNDM) 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. 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. 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 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).
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 positions.

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

page 140.

Transmission Gear Selector

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 press the accelerator pedal when shifting out of

PARK or NEUTRAL.

NOTE:

After selecting any gear range, wait a moment to allow the

selected gear to engage before accelerating. This is espe

cially 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 hill, apply the parking brake before

shifting the transmission to 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 ignition OFF.



Remove the key fob from the vehicle.

NOTE:

On four-wheel drive vehicles, be sure that the transfer

case is in a drive position.

STARTING AND OPERATING

139

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 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), and is not

blinking.



With the brake pedal released, verify that the gear

selector 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.
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.

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 should be used for 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

page 140. Under

these conditions, using 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

depending 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. 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

page 140.

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 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.

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.

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.

STARTING AND OPERATING

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 indi

cates the transmission may not re-engage after engine

shutdown, perform this procedure only in a desired

location (preferably, at an authorized dealer).



Even if the transmission can be reset, we recommend

that you visit an authorized dealer at your earliest

possible convenience. An authorized dealer has diag

nostic equipment to assess the condition of your trans

mission.



If the transmission cannot be reset, authorized dealer

service is required.

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.

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 feature can

also provide you with more control during passing, city

driving, cold slippery conditions, mountain driving, trailer

towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into

the MANUAL (M) position (beside the DRIVE position). The

current transmission gear will be displayed in the

instrument cluster. In AutoStick mode, you can use the

gear selector (in the MANUAL position) to manually shift

the transmission.
AutoStick mode has the following operational benefits:



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 or SECOND gear

(or THIRD gear, in 4L range). Tapping (+) (at a stop) will

allow starting in SECOND gear. Starting out in SECOND

or THIRD gear can be helpful in snowy or icy conditions.



If a requested downshift would cause the engine to

overspeed, that shift will not occur.



The system will ignore attempts to upshift at too low of

a vehicle speed.



Holding the gear selector in the (-) position will down

shift the transmission to the lowest gear possible at the

current speed.



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.

NOTE:

When Hill Descent Control is enabled, AutoStick is not

active.
To disengage AutoStick mode, return the gear selector to

the DRIVE position. You can shift in or out of the AutoStick

position at any time without taking your foot off the

accelerator pedal.

FOUR–WHEEL DRIVE OPERATION

WARNING!

Do not downshift for additional engine braking on a

slippery surface. The drive wheels could lose their grip

and the vehicle could skid, causing a collision or

personal injury.

WARNING!

Failure to engage a transfer case position completely

can cause transfer case damage or loss of power and

vehicle control. You could have a collision. Do not drive

the vehicle unless the transfer case is fully engaged.

Four-Wheel Drive Gear Selector

The transfer case provides four positions:



2H — Two-Wheel Drive High Range



4H — Four-Wheel Drive High Range



N (Neutral)



4L — Four-Wheel Drive Low Range

For additional information on the appropriate use of each

transfer case position, see the following:
2H
Two-Wheel Drive High Range — This range is for normal

street and highway driving on dry, hard surfaced roads.
4H
Four-Wheel Drive High Range — This range maximizes

torque to the front driveshaft, forcing the front and rear

wheels to rotate at the same speed. This range provides

additional traction for loose, slippery road surfaces only.

N (Neutral)

N (Neutral) — This range disengages both the front and

rear driveshafts from the powertrain. To be used for flat

towing behind another vehicle

page 176.

4L
Four-Wheel Drive Low Range — This range provides low

speed four-wheel drive. It maximizes torque to the front

driveshaft, forcing the front and rear wheels to rotate at

the same speed. This range provides additional traction

and maximum pulling power for loose, slippery road

surfaces only. Do not exceed 25 mph (40 km/h).
The transfer case is intended to be driven in the 2H

position for normal street and highway conditions, such as

hard-surfaced roads.
In the event that additional traction is required, the

transfer case 4H and 4L positions can be used to lock the

front and rear driveshafts together, forcing the front and

rear wheels to rotate at the same speed. The 4H and 4L

positions are intended for loose, slippery road surfaces

only and not intended for normal driving. Driving in the 4H

and 4L positions on hard-surfaced roads will cause

increased tire wear and damage to the driveline

components. For further information on shifting into 4H or

page 141.

The instrument cluster alerts the driver that the vehicle is

in four-wheel drive, and the front and rear driveshafts are

locked together. The light will illuminate when the transfer

case is shifted into the 4H position.
When operating your vehicle in 4L, the engine speed will

be approximately three times (four times for Rubicon

models) that of the 2H or 4H positions at a given road

speed. Take care not to overspeed the engine.
Proper operation of four-wheel drive vehicles depends on

tires of equal size, type, and circumference on each wheel.

Any difference will adversely affect shifting and cause

damage to the transfer case.
Because four-wheel drive provides improved traction,

there is a tendency to exceed safe turning and stopping

speeds. Do not go faster than road conditions permit.

Shifting Procedures

2H TO 4H OR 4H TO 2H

Shifting between 2H and 4H can be made with the vehicle

stopped or in motion. The preferred shifting speed would

be 0 to 45 mph (72 km/h). With the vehicle in motion, the

transfer case will engage/disengage faster if you

momentarily release the accelerator pedal after

completing the shift. Do not accelerate while shifting the

transfer case. Apply a constant force when shifting the

transfer case lever.

WARNING!

You or others could be injured or killed if you leave the

vehicle unattended with the transfer case in the (N)

Neutral position without first fully engaging the parking

brake. The transfer case (N) Neutral position

disengages both the front and rear driveshafts from the

powertrain, and will allow the vehicle to roll, even if the

automatic transmission is in PARK (or manual

transmission is in gear). The parking brake should

always be applied when the driver is not in the vehicle.

142

STARTING AND OPERATING

NOTE:



Do not attempt to make a shift while only the front or

rear wheels are spinning. The front and rear driveshaft

speeds must be equal for the shift to take place.

Shifting while only the front or rear wheels are spinning

can cause damage to the transfer case.



Delayed shifts out of four-wheel drive may be experi

enced due to uneven tire wear, low or uneven tire pres

sures, excessive vehicle loading, or cold temperatures.



Shifting effort will increase with speed, this is normal.

During cold weather, you may experience increased effort

in shifting until the transfer case fluid warms up. This is

normal.

4H TO 4L OR 4L TO 4H

With the vehicle rolling at 1 to 3 mph (2 to 5 km/h), shift

an automatic transmission into NEUTRAL (N), or press the

clutch pedal on a manual transmission. While the vehicle

is coasting at 1 to 3 mph (2 to 5 km/h), shift the transfer

case lever firmly to the desired position. Do not pause with

the transfer case in N (Neutral). Once the shift is

completed, place the automatic transmission into DRIVE

or release the clutch pedal on a manual transmission.

NOTE:

Shifting into or out of 4L is possible with the vehicle

completely stopped; however, difficulty may occur due to

the mating teeth not being properly aligned. Several

attempts may be required for clutch teeth alignment and

shift completion to occur. The preferred method is with the

vehicle rolling at 1 to 3 mph (2 to 5 km/h). Avoid

attempting to engage or disengage 4L with the vehicle

moving faster than 1 to 3 mph (2 to 5 km/h).

This transfer case is designed to be driven in the

two-wheel drive position (2H) or four-wheel drive position

(4H AUTO) for normal street and highway conditions on dry

hard surfaced roads.
For variable driving conditions, the 4H AUTO mode can be

used. In this mode, the front axle is engaged, but the

vehicle's power is sent to the rear wheels. Four-wheel drive

will be automatically engaged when the vehicle senses a

loss of traction. Because the front axle is engaged, this

mode will result in lower fuel economy than the 2H mode.
In the event that additional traction is required, the

transfer case 4H and 4L positions can be used to lock the

front and rear driveshafts together, forcing the front and

rear wheels to rotate at the same speed. The 4H and 4L

positions are intended for loose, slippery road surfaces

only and not intended for normal driving. Driving in the 4H

and 4L positions on hard-surfaced roads will cause

increased tire wear and damage to the driveline

components. For further information on shifting into 4H or

page 143.

The instrument cluster alerts the driver that the vehicle is

The Trac-Lok rear axle provides a constant driving force to

both rear wheels and reduces wheel spin caused by the

loss of traction at one driving wheel. If traction differs

between the two rear wheels, the differential

automatically proportions the usable torque by providing

more torque to the wheel that has traction.
Trac-Lok is especially helpful during slippery driving

due to driving surface differences or vehicle loading. In

order for the stabilizer/sway bar to disconnect/reconnect,

the right and left halves of the bar must be aligned. This

alignment may require that the vehicle be driven onto level

ground or rocked from side to side.

WARNING!

Ensure the stabilizer/sway bar is reconnected before

driving on hard surfaced roads or at speeds above

18 mph (29 km/h); a disconnected stabilizer/sway bar

may contribute to the loss of vehicle control, which

could result in serious injury. Under certain

circumstances, the front stabilizer/sway bar enhances

vehicle stability and assists with vehicle control. The

system monitors vehicle speed and will attempt to

reconnect the stabilizer/sway bar at speeds over

18 mph (29 km/h). This is indicated by a flashing or

solid Sway Bar Indicator Light. Once vehicle speed is

reduced below 14 mph (22 km/h), the system will once

again attempt to return to off-road mode.

ELECTRO-HYDRAULIC POWER STEERING

Your vehicle is equipped with an Electro-Hydraulic Power

Steering system that provides increased vehicle response

and ease of maneuverability. The system adapts to

different driving conditions. If the Electro-Hydraulic Power

Steering system experiences a fault that prevents it from

providing power steering assist, then the system will

provide mechanical steering capability.

WARNING!

If the stabilizer/sway bar will not return to on-road mode,

the Sway Bar Indicator Light will flash in the instrument

cluster and vehicle stability may be reduced. Do not

attempt to drive the vehicle over 18 mph (29 km/h).

Driving faster than 18 mph (29 km/h) with a discon

nected stabilizer/sway bar may contribute to the loss of

vehicle control, which could result in serious injury.

CAUTION!

Extreme steering maneuvers may cause the electrically

driven pump to reduce or stop power steering

assistance in order to prevent damage to the system.

Normal operation will resume once the system is

allowed to cool.

STARTING AND OPERATING

147

If the “SERVICE POWER STEERING” message and a

flashing icon are displayed on the instrument cluster

screen, it indicates that the vehicle needs to be taken to

an authorized dealer for service. It is likely the vehicle has

lost power steering assistance

page 108.

If the “POWER STEERING HOT” message and an icon are

displayed on the instrument cluster screen, it indicates

that extreme steering maneuvers may have occurred,

which caused an over temperature condition in the power

steering system. You will lose power steering assistance

momentarily until the over temperature condition no

longer exists. Once driving conditions are safe, pull over

and let vehicle idle for a few moments until the light turns

off

page 108.

NOTE:



Even if power steering assistance is no longer opera

tional, it is still possible to steer the vehicle. Under

these conditions there will be a substantial increase in

steering effort, especially at very low vehicle speeds

and during parking maneuvers.



If the condition persists, see an authorized dealer for

service.

equipped with ACC

page 151.

NOTE:



If the ACC sensor detects a vehicle ahead, ACC will

apply limited braking or accelerate (not to exceed the

original set speed) automatically to maintain a preset

following distance, while matching the speed of the

vehicle ahead.



Any chassis/suspension or tire size modifications to

the vehicle will affect the performance of the Adaptive

Cruise Control and Forward Collision Warning system.



Fixed Speed Cruise Control (ACC not enabled) will not

detect vehicles directly ahead of you. Always be aware

of the feature selected

page 381.

WARNING!

Cruise Control can be dangerous where the system

cannot maintain a constant speed. Your vehicle could

go too fast for the conditions, and you could lose control

and have an accident. Do not use Cruise Control in

heavy traffic or on roads that are winding, icy,

snow-covered or slippery.
