NGINE

AILS

TART

If the engine fails to start after you have followed

the "Normal Starting" procedure and has not

experienced an extended park condition (i.e.,

parked for more than 30 days), it may be flooded.

Push the accelerator pedal all the way to the floor

and hold it there while the engine is cranking. This

should clear any excess fuel in case the engine is

flooded. The starter motor will engage

automatically, run for 10 seconds, and then

disengage. Once this occurs, release the

accelerator pedal and brake pedal, wait 10 to

15 seconds, then repeat the “Normal Starting”

procedure.

WARNING!

If vehicle speed is above 1.2 mph (1.9 km/h),

the transmission will default to NEUTRAL until

the vehicle speed drops below 1.2 mph (1.9 km/

h). A vehicle left in the NEUTRAL position can

roll. As an added precaution, always apply the

parking brake when exiting the vehicle.

recommended.

FTER

TARTING

The idle speed is controlled automatically, and it

will decrease as the engine warms up.

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 coiled and

strapped right behind the engine air cleaner filter

assembly from the manufacturer.

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.
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

detrimental 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

page 343.

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. Please check your

oil level with the engine oil indicator often during the

break-in period. Add oil as required.

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 auto

matic transmission 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

page 323.

CAUTION!

To prevent damage to the starter, do not

continuously crank the engine for more than

10 seconds at a time. Wait 10 to 15 seconds

before trying again.

WARNING!

Remember to disconnect the engine block

heater cord before driving. Damage to the

110-115 Volt electrical cord could cause

electrocution.

CAUTION!

Never use non-detergent oil or straight mineral

oil in the engine or damage may result.

STARTING AND OPERATING

PARKING BRAKE

LECTRIC

ARK

RAKE

(EPB)

Your vehicle is equipped with an EPB that offers

simple operation, and some additional features

that make the parking brake more convenient and

useful.
The parking brake is primarily intended to prevent

the vehicle from rolling while parked. Before

leaving the vehicle, make sure the parking brake is

applied. Also, be certain to leave the transmission

in PARK.
You can engage the parking brake in two ways:



Manually, by applying the parking brake switch.



Automatically, by enabling the Auto Park Brake

feature in the Customer Programmable

Features section of the Uconnect settings.

The parking brake switch is located on the

instrument panel to the left of the steering wheel

(below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on the

switch momentarily. You may hear a sound from

the back of the vehicle while the parking brake

engages. Once the parking brake is fully engaged,

the BRAKE telltale light in the instrument cluster

and an indicator on the switch will illuminate. If

your foot is on the brake pedal while you apply the

parking brake, you may notice a small amount of

brake pedal movement. The parking brake can be

applied even when the ignition switch is OFF but

the BRAKE telltale light will not illuminate,

however, it can only be released when the ignition

is in the ON/RUN position.

NOTE:

The EPB fault light will illuminate if the EPB switch

is held for longer than 20 seconds in either the

released or applied position. The light will extin

guish upon releasing the switch.

If the Auto Park Brake feature is enabled, the

parking brake will automatically engage whenever

the transmission is placed into PARK. If your foot is

on the brake pedal, you may notice a small amount

of brake pedal movement while the parking brake

is engaging.
The parking brake will release automatically when

the ignition is ON, the transmission is in DRIVE or

REVERSE, the driver seat belt is buckled, and an

attempt is made to drive away.
To release the parking brake manually, the ignition

switch must be in the ON/RUN position. Put your

foot on the brake pedal, then push the EPB switch

down momentarily. You may hear a sound from the

back of the vehicle while the parking brake

disengages. You may also notice a small amount of

movement in the brake pedal. Once the parking

brake is fully disengaged, the BRAKE telltale light

in the instrument cluster and the LED indicator on

the switch will extinguish.

NOTE:

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. 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.

STARTING AND OPERATING

127

(Continued)

If exceptional circumstances should make it

necessary to engage the parking brake while the

vehicle is in motion, maintain upward pressure on

the EPB switch for as long as engagement is

desired. The BRAKE telltale light will illuminate,

and a continuous chime will sound. The rear stop

lamps will also be illuminated automatically while

the vehicle remains in motion.
To disengage the parking brake while the vehicle is

in motion, release the switch. If the vehicle is

brought to a complete stop using the parking

brake, when the vehicle reaches approximately

3 mph, (5 km/h) the parking brake will remain

engaged.

In the unlikely event of a malfunction of the EPB

system, a yellow EPB fault light will illuminate. This

may be accompanied by the BRAKE telltale light

flashing. In this event, urgent service of the EPB

system is required. Do not rely on the parking

brake to hold the vehicle stationary.

UTO

ARK

RAKE

The EPB can be programmed to be applied

automatically whenever the vehicle is at a

standstill and the transmission is placed in PARK.

Auto Park Brake is enabled and disabled by

customer selection through the customer

programmable features section of the Uconnect

Settings

page 219.

Any single Auto Park Brake application can be

bypassed by pushing the EPB switch to the release

position while the transmission is placed in PARK.

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.



When exiting the vehicle, always turn the igni

tion OFF, secure the key fob, and lock your

vehicle.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil

dren 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 a vehicle equipped with Keyless

Enter ‘n Go™ in the ON/RUN position. A child

could operate 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.



Always fully apply the parking brake when

leaving your vehicle, or it may roll and cause

damage or injury. Also be certain to leave the

transmission in PARK. Failure to do so may

allow the vehicle to roll and cause damage or

injury.

CAUTION!

If the Brake System Warning Light remains on

with the parking brake released, a brake system

malfunction is indicated. Have the brake system

serviced by an authorized dealer immediately.

WARNING!

Driving the vehicle with the parking brake

engaged, or repeated use of the parking brake

to slow the vehicle may cause serious damage to

the brake system. Be sure the parking brake is

fully disengaged before driving; failure to do so

can lead to brake failure and a collision.

AINTENANCE

ODE

We recommend having your brakes serviced by an

authorized dealer. You should only make repairs

for which you have the knowledge and the right

equipment. You should only enter Brake

Maintenance Mode during brake service.
When servicing your rear brakes, it may be

necessary for you or your technician to push the

rear piston into the rear caliper bore. With the EPB

system, this can only be done after retracting the

EPB actuator. Fortunately, actuator retraction can

be done easily by entering the Brake Maintenance

Mode through the Uconnect Settings in your

vehicle. This menu-based system will guide you

through the steps necessary to retract the EPB

actuator in order to perform rear brake service.
Maintenance Mode has requirements that must be

met in order to be activated:



The vehicle must be at a standstill.



The parking brake must be unapplied.



The transmission must be in PARK or NEUTRAL.

While in Maintenance Mode, the EPB fault lamp

will flash continuously while the ignition is ON.

STARTING AND OPERATING

(Continued)

When brake maintenance work is complete, the

following steps must be followed to reset the

parking brake system to normal operation:



Ensure the vehicle is at a standstill.



Press the brake pedal with moderate force.



Apply the EPB Switch.

AUTOMATIC TRANSMISSION

You must press and hold the brake pedal while

shifting out of PARK.

WARNING!

You can be badly injured working on or around a

motor vehicle. Do only that service work for

which you have the knowledge and the right

equipment. If you have any doubt about your

ability to perform a service job, take your vehicle

to a competent mechanic.

WARNING!



Never use the PARK (P) position as a substi

tute 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 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 indi

cator solidly indicates PARK without blinking.

Ensure that the vehicle is completely stopped,

and the PARK position is properly indicated,

before exiting the vehicle.



It is dangerous to shift out of PARK or

NEUTRAL (N) 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.

WARNING!



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 transmis

sion is locked in PARK, securing the vehicle

against unwanted movement.



When exiting the vehicle, always make sure

the ignition 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 chil

dren 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 transmis

sion 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 ON/RUN position.

A child could operate power windows, other

controls, or move the vehicle.

STARTING AND OPERATING

GNITION

ARK

NTERLOCK

This vehicle is equipped with an Ignition Park

Interlock which requires the transmission to be in

PARK (P) 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 ON/RUN position (even though the

engine will be off). Ensure that the transmission is

in PARK, and the ignition is OFF (not in the ON/RUN

position) before exiting the vehicle.

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.

8-S

PEED

UTOMATIC

RANSMISSION

The transmission is controlled using a rotary

electronic gear selector located on the center

console. The transmission gear range (PRND) is

displayed both above the gear selector and in the

instrument cluster. To select a gear range, simply

rotate the gear selector. You must press the brake

pedal to shift the transmission out of PARK (or

NEUTRAL, when the vehicle is stopped or moving at

low speeds). To shift past multiple gear ranges at

once (such as PARK to DRIVE), simply rotate the

gear selector to the appropriate detent. 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 has only PARK,

REVERSE, NEUTRAL, and DRIVE positions. Manual

downshifts can be made using the steering wheel

mounted paddle shifters. Pulling the -/+ switches

(on the steering wheel) while in the DRIVE position

will select the highest available transmission gear,

and will display that gear limit in the instrument

cluster as 1, 2, 3, etc. Some models will display

both the selected gear limit, and the actual current

gear, while in AutoStick mode.

CAUTION!

Damage to the transmission may occur if the

following precautions are not observed:



Shift into or out of PARK or REVERSE (R) only

after the vehicle has come to a complete stop.



Do not shift between PARK, REVERSE,

NEUTRAL, or DRIVE (D) when the engine is

above idle speed.



Before shifting into any gear, make sure your

foot is firmly pressing the brake pedal.

STARTING AND OPERATING

131

Transmission Gear Selector

Gear Ranges

Do not press the accelerator pedal when shifting

from PARK (P) or NEUTRAL (N) into another gear

range.

NOTE:

After selecting any gear range, wait a moment to

allow the selected gear to engage before acceler

ating. 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 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.

The following indicators should be used to ensure

that you have properly engaged the transmission

into the PARK position:



When shifting into PARK, rotate the shifter all

the way counterclockwise until the indicator

displays PARK.



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 (P) if you must exit the vehicle.

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.

132

STARTING AND OPERATING

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.
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 133. Under these conditions, using a lower

gear will improve performance and extend

transmission life by reducing excessive shifting

and heat build-up.

During cold temperatures, transmission operation

may be modified depending on engine and

transmission temperature as well as vehicle

speed. This feature improves warm-up time of the

engine and transmission to achieve maximum

efficiency. Engagement of the torque converter

clutch is inhibited until the transmission fluid is

warm. Normal operation will resume once the

transmission temperature has risen to a suitable

level.

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.
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

engine shutdown, perform this procedure only in a

desired location (preferably, at an authorized

dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if

possible. If not, shift the transmission to

NEUTRAL (N).

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

recommend that you visit an authorized dealer at

your earliest possible convenience. An authorized

dealer has diagnostic equipment to assess the

condition of your transmission.
If the transmission cannot be reset, authorized

dealer service is required.

CAUTION!

Towing the vehicle, coasting, or driving for any

other reason with the transmission in NEUTRAL

can cause severe transmission damage.

AutoStick — If Equipped

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.

AutoStick Paddle Shifters

Operation
To activate AutoStick mode, tap one of the paddle

shifters on the steering wheel. Tapping the (-)

paddle shifters to enter AutoStick mode will

downshift the transmission to the next lower gear,

while tapping (+) to enter AutoStick mode will

retain the current gear. The current transmission

gear will be displayed in the instrument cluster.

In AutoStick mode, you can use the paddle shifters,

to manually shift the transmission. Tapping the (-)

paddle shifters, will downshift the transmission to

the next lower gear. Tapping the (+) paddle

shifters, will upshift the transmission to the next

highest gear.

NOTE:

The paddle shifters (if equipped) may be disabled

(or re-enabled, as desired) using the Uconnect

Programmable Settings.
In AutoStick mode, the transmission will shift up or

down when (+/-) is manually selected by the driver,

unless an engine lugging or overspeed condition

would result. It will remain in the selected gear

until another upshift or downshift is chosen, except

as follows.



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 trans

mission as the vehicle is accelerated.



You can start out, from a stop, in FIRST or

SECOND gear. Tapping (+) at a stop will allow

starting in SECOND gear. Starting out in

SECOND gear can be helpful in snowy or icy

conditions.



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.



Holding the (-) paddle pressed, will downshift

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. The

vehicle will force an upshift, but it will stay in

AutoStick mode.

To disengage AutoStick mode, push and hold the

(+) paddle shifters until "D" is once again indicated

in the instrument cluster. You can shift in or out of

AutoStick mode at any time without taking your

foot off the accelerator pedal.

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.

The Quadra-Trac II system comes equipped with a

customer-selectable electronically operated

on-demand transfer case with active torque

management in all driveable ranges. This transfer

case provides the following operating range

positions:



4WD HI



N (NEUTRAL)



4WD LOW

When additional tractive effort and torque are

required, the 4WD LOW position can be used. The

4WD LOW position is intended for loose, slippery

road surfaces only. Driving in the 4WD LOW

position on dry, hard-surfaced roads may cause

increased tire wear and damage to driveline

components.
When operating your vehicle in 4WD LOW, the

engine speed is approximately three times that of

the normal 4WD HI position at a given road speed.

Take care not to overspeed the engine and do not

exceed 25 mph (40 km/h).

STARTING AND OPERATING

135

Proper operation of four-wheel drive vehicles

depends on tires of equal size, type, and

circumference on each wheel. Any difference will

adversely affect performance and function of 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.

HIFT

OSITIONS

For additional information on the appropriate use

of each four-wheel drive system mode position,

see the information below:

4WD HI

This is the default operating range for daily use.

N (NEUTRAL)

This range disengages the driveline from the

powertrain. It is used for towing your vehicle

behind another vehicle

page 196.

4WD LOW

This range is for low speed four-wheel drive. It

provides an additional gear reduction which allows

for increased torque to be delivered to both the

front and rear wheels while providing maximum

pulling power for loose, slippery road surfaces only.

Do not exceed 25 mph (40 km/h).

HIFTING

ROCEDURES

4WD HI To 4WD LOW

With the vehicle at speeds of 0 to 3 mph (0 to

5 km/h), the ignition switch in the ON/RUN

position and the engine running, shift the

transmission into NEUTRAL (N), push and hold the

4WD LOW button until the 4WD LOW indicator light

begins to flash in the instrument cluster. When the

shift is complete, the 4WD LOW indicator light will

remain on solid.

4WD LOW Button

NOTE:

If shift conditions/interlocks are not met, a “To

Complete 4WD Shift Put Transmission In Neutral”

or a “To Complete 4WD Shift Speed Must Be Below

3 MPH” or a “To Complete 4WD Shift Allow Engine

To Return To Idle” message will flash from the

instrument cluster display

page 99.

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 drive shafts from the powertrain

and will allow the vehicle to roll, even if the

transmission is in PARK. The parking brake

should always be applied when the driver is not

in the vehicle.

STARTING AND OPERATING

4WD LOW To 4WD HI

With the vehicle at speeds of 0 to 3 mph

(0 to 5 km/h), the ignition switch in the ON position

or the engine running, shift the transmission into

NEUTRAL (N), push and hold the 4WD LOW button

until the 4WD LOW indicator light begins to flash in

the instrument cluster. When the shift is complete,

the 4WD LOW indicator light will remain off.

NOTE:



If shift conditions/interlocks are not met —

“4WD Shift Cancelled” or “4WD Shift Aborted/

Retry Shift” message will be displayed on the

instrument cluster. To reattempt shift, put the

transmission in NEUTRAL (N) and push and hold

the 4WD LOW button.



If shift conditions/interlocks are not met, a “To

Complete 4WD Shift Put Transmission In

Neutral” or a “To Complete 4WD Shift Speed

Must Be Below 3 MPH” or a “To Complete 4WD

Shift Allow Engine To Return To Idle” message

will flash from the instrument cluster display

page 99.



Shifting into or out of 4WD LOW is possible with

the vehicle completely stopped; however, diffi

culty may occur due to the mating clutch 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

0 to 3 mph (0 to 5 km/h). If the vehicle is

moving faster than 3 mph (5 km/h), the transfer

case will not allow the shift.

The Quadra-Trac II System features two torque

transfer couplings. The couplings include an

Electronic Limited-Slip Differential (ELSD) rear axle

and the Quadra-Trac II transfer case. The ELSD

axle is fully automatic and requires no driver input

to operate. Under normal driving conditions, the

unit functions as a standard axle, balancing torque

evenly between left and right wheels. With a

traction difference between left and right wheels,

the coupling will sense a speed difference. As one

wheel begins to spin faster than the other, torque

will automatically transfer from the wheel that has

less traction, to the wheel that has traction. While

the transfer case and axle coupling differ in design,

their operation is similar. Follow the Quadra-Trac II

transfer case shifting information, preceding this

section, for shifting this system.

Your vehicle may be equipped with an electronic

disconnecting stabilizer/sway bar. This system

allows greater front suspension travel in off-road

situations.
This system is controlled by the SWAY BAR switch

located on the instrument panel (to the right of the

gear selector).

SWAY BAR Switch

Push the SWAY BAR switch to activate the system.

Push the switch again to deactivate the system.

The Sway Bar Indicator Light (located in the

instrument cluster) will illuminate when the bar is

disconnected. The Sway Bar Indicator Light will

flash during activation transition, or when

activation conditions are not met.

STARTING AND OPERATING

137

The stabilizer/sway bar should remain in on-road

mode during normal driving conditions.

To disconnect the stabilizer/sway bar, shift to 4WD

LOW and push the SWAY BAR switch to obtain the

off-road position

page 134. The Sway Bar

Indicator Light will flash until the stabilizer/sway

bar has been fully disconnected.

NOTE:

The stabilizer/sway bar may be torque locked due

to left and right suspension height differences.

This condition is 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.
To return to on-road mode, push the SWAY BAR

switch again.

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.

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

disconnected stabilizer/sway bar may contribute

to the loss of vehicle control, which could result

in serious injury.

STARTING AND OPERATING

Selec-Terrain consists of the following positions:



ROCK – Off-road calibration is only available in

4WD LOW. The vehicle is raised (if equipped

with air suspension) for improved ground clear

ance. Traction-based tuning with improved

steerability for use on high traction off-road

surfaces. Use for low speed obstacles such as

large rocks, deep ruts, etc. If equipped with air

suspension, the vehicle level will change to

Off-Road 2 (OR2). If the Selec-Terrain switch is

in ROCK mode, and the transfer case is

switched from 4WD LOW to 4WD HI, the

Selec-Terrain system will return to AUTO.



SAND/MUD – Off-road calibration for use on low

traction surfaces such as mud or sand. Driveline

is maximized for traction. Some binding may be

felt on less forgiving surfaces. The electronic

brake controls are set to limit traction control

management of throttle and wheel spin. If

equipped with air suspension, the level will

change to Off-Road 1 (OR1).



SNOW – Tuning set for additional stability in

inclement weather. Use on and off-road on

loose traction surfaces such as snow. When in

SNOW mode (depending on certain operating

conditions), the transmission may use SECOND

gear (rather than FIRST gear) during launches,

to minimize wheel slippage. If equipped with air

suspension, the default ride height for SNOW is

Normal Ride Height (NRH).



AUTO – Fully automatic full-time four-wheel

drive operation can be used on and off-road.

Balances traction with seamless steering feel to

provide improved handling and acceleration

over two-wheel drive vehicles. If the suspension

is already in OR1 or OR2, the vehicle will not

lower to NRH with Auto selection as to maintain

capability.

NOTE:

If equipped with air suspension, the level will only

raise to Normal Ride Height (NRH) in the AUTO

mode. If the vehicle is in OR1 or OR2 the height will

not lower automatically until defined speed

thresholds are exceeded.



SPORT – This mode is only available in 4WD HI.

When activated, the engine and transmission,

steering and suspension (if equipped with air

suspension) are all set to their SPORT settings.

SPORT mode will provide improved throttle

response and modified transmission shift

points as well as firmer suspension and

steering, the vehicle will also be dropped to Aero

Height for an enhanced driving experience.

When SPORT mode has been activated, an indi

cator light will illuminate in the instrument

The Quadra-Lift Air Suspension system provides

full time load leveling capability along with the

benefit of vehicle height adjustment by a toggle

switch. The vehicle will automatically raise and

lower the ride height to adapt to the appropriate

driving conditions. At higher speeds, the vehicle

will lower to an aerodynamic ride height and when

operating in off-road modes, the vehicle will raise

the ride height accordingly. The buttons near the
