STARTING AND OPERATING

(Continued)

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.

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 Warning 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.

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.

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.

126

STARTING AND OPERATING

(Continued)

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 Warning

Light will flash continuously while the ignition is

ON.
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.



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.

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 will NOT shift out of the PARK

position if the engine is not running even when the

brakes are applied. 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).



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.

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.

WARNING!

128

STARTING AND OPERATING

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.

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.

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.

STARTING AND OPERATING

129

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.

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 130. Under these conditions, using a lower

gear will improve performance and extend

transmission life by reducing excessive shifting

and heat buildup.
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.

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.
For Recreational Towing see

page 195.

For Towing A Disabled Vehicle see

page 326.

130

STARTING AND OPERATING

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.

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.
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.

SPORT MODE — IF EQUIPPED

SPORT Mode

Your vehicle is equipped with a Sport Mode

feature. When activated, the engine and

transmission, steering and suspension (if

equipped with air suspension) are all set to their

FOUR-WHEEL DRIVE OPERATION

The driveline is equipped with a Front Axle

Disconnect (FAD) for the one-speed and two-speed

drivelines. The FAD operation is fully automated

and controlled by the Drivetrain Control Module

(DTCM). It does not require any customer input to

engage. The FAD is set to connect, disconnect and

provide 4WD function based on certain set

conditions detected by the DTCM, including but not

limited to the following:



Ambient temperature



Wipers



Selec-Terrain Mode selection



Wheel-slip detection

The FAD is actuated only in 4WD HI range and

stays connected for 4WD LOW.

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).

132

STARTING AND OPERATING

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 following:

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 195.

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).

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

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

134

STARTING AND OPERATING

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. The stabilizer/

sway bar should remain in on-road mode during

normal driving conditions.
NOTE:

If the electronic disconnecting stabilizer/sway bar

is disconnected and then driven at speeds above

18 mph (29 km/h), the system will reconnect for

driver safety. The Sway Bar Indicator Light will

continue to flash as the system waits for the driver

to slow the vehicle and will automatically

disconnect again unless the driver cancels the

request with the SWAY BAR switch. The system can

cancel the pending disconnect request if drivetrain

changes are made (e.g. 4WD HI to 4WD LOW)

based on road conditions.

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

LOW and push the SWAY BAR switch to obtain the

off-road position

page 131. 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.

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.

Selec-Terrain

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

cluster.

QUADRA-LIFT — IF EQUIPPED

ESCRIPTION

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

terrain switch in the center console area can be

used to set preferred ride height to match the

appropriate conditions.

Quadra-Lift Switch



Off-Road 2 (OR2) (Non-TrailHawk raises the

vehicle approximately 2.4 inches [60 mm])

(TrailHawk raises the vehicle approximately

3.0 inches [75 mm]) – This position is intended

for off-road use only where maximum ground

clearance is required. To enter OR2, push the

UP button twice from the NRH position or once

from the OR1 position while vehicle speed is

below 20 mph (32 km/h). While in OR2, if the

vehicle speed exceeds 25 mph (40 km/h) the

vehicle height will be automatically lowered to

OR1

page 199.



Off-Road 1 (OR1) (Raises the vehicle approxi

mately 1.6 inches [40 mm]) – This is the

primary position for all off-road driving until OR2

is needed. Push the UP button once from the

NRH position while the vehicle speed is below

38 mph (61 km/h). When in the OR1 position, if

the vehicle speed remains between 40 mph

(64 km/h) and 50 mph (80 km/h) for greater

than 20 seconds or if the vehicle speed exceeds

50 mph (80 km/h), the vehicle will be automat

ically lowered to NRH



Normal Ride Height (NRH) 0.0 inches (0 mm) –

This is the standard position of the suspension

and is meant for normal driving.



Aero Height (Lowers the vehicle approximately

-0.8 inches [-21 mm] Front and -1.0 inches

[-25 mm] Rear) – This position provides

improved aerodynamics by lowering the vehicle.

The vehicle will automatically enter Aero when

the vehicle speed remains between 62 mph

(100 km/h) and 66 mph (106 km/h) for greater

than 20 seconds or if the vehicle speed exceeds

66 mph (106 km/h). The vehicle will return to

NRH from Aero if the vehicle speed remains

between 30 mph (48 km/h) and 35 mph

(56 km/h) for greater than 20 seconds or if the

vehicle speed falls below 30 mph (48 km/h).

The vehicle will enter Aero, regardless of vehicle

speed if the vehicle is in SPORT mode.



Entry/Exit Height (Lowers the vehicle approxi

mately -1.8 inches [-46 mm] Front and

-2.0 inches [-50 mm] Rear) – This position

lowers the vehicle for easier passenger entry

and exit as well as lowering the rear of the

vehicle for easier loading and unloading of

cargo. To enter Entry/Exit, push the DOWN

button twice from NRH while the vehicle speed

is below 4 mph (6 km/h). To exit Entry/Exit,

push the UP button twice while in Entry/Exit or

drive the vehicle over 6 mph (10 km/h).

NOTE:

Automatic lowering of the vehicle into Entry/Exit

can be enabled through the Uconnect Touch

screen Radio by selecting the “Auto Entry/Exit”

setting. If this feature is enabled, the vehicle will

only lower if the gear selector is in PARK, the

terrain switch is in AUTO, the transfer case is in

AUTO and the vehicle level is either in Normal or

Aero Height. The vehicle will not automatically

lower to Entry/Exit height if the air suspension level

is in OR2 or OR1. If the vehicle is equipped with

Intrusion Theft Module (ITM), the lowering will be

suppressed when the ignition is switched OFF and

the door is open to prevent setting the alarm off.
The Selec-Terrain system will automatically change

the vehicle to the proper height based on the

position of the Selec-Terrain switch. The height can

be changed from the default Selec-Terrain setting

by normal use of the air suspension buttons

page 134.

The system requires that the engine be running for

all changes. When lowering the vehicle all of the

doors must be closed. If a door is opened at any

time while the vehicle is lowering the change will

not be completed until the open door(s) is/are

closed.
The Quadra-Lift Air Suspension system uses a

lifting and lowering pattern which keeps the

headlights from incorrectly shining into oncoming

traffic. When raising the vehicle, the rear of the

vehicle will move up first and then the front. When

lowering the vehicle, the front will move down first

and then the rear.
After the engine is turned off, it may be noticed that

the air suspension system operates briefly; this is

normal. The system is correcting the position of the

vehicle to ensure a proper appearance.
To assist with changing a spare tire, the

Quadra-Lift Air Suspension system has a feature

which allows the automatic leveling to be disabled

Default Ride Height



Select Aero Height or Normal Ride Height as the

default for all vehicle speeds and operation.

This is the selected height that the suspension

will level for speed changes (e.g. raising from

Entry/Exit Height at speed, lowering from Off

Road Height at speed, etc.).



Default ride height can be changed by manually

adjusting the ride height switch to Normal Ride

Height or Aero Height and staying in the

selected height for 2.5 seconds. It will be stored

as the default ride height and the height will be

maintained until a new default ride height is

selected.
