PERATION

The indicator lamps 2 through 5 will illuminate to

show the current position of the vehicle. Flashing

indicator lamps will show a position which the

system is working to achieve. When raising, if

multiple indicator lamps are flashing on the UP

position the system is working to achieve. When

lowering, if multiple indicators are flashing on the

DOWN button the lowest solid indicator lamp is the

position the system is working to achieve.
Pushing the UP button once will move the

suspension one position higher from the current

position, assuming all conditions are met (i.e.

engine running, speed below threshold, etc). The

UP button can be pushed multiple times. Each

push will raise the requested level by one position

up to a maximum position of OR2 or the highest

position allowed based on current conditions

(i.e. vehicle speed, etc).
Pushing the DOWN button once will move the

suspension one position lower from the current

level, assuming all conditions are met (i.e. engine

running, doors closed, speed below threshold, etc).

The DOWN button can be pressed multiple times.

Each push will lower the requested level by one

position down to a minimum of Entry/Exit Height or

the lowest position allowed based on current

conditions (i.e. vehicle speed, etc.)

Selec-Terrain combines the capabilities of the

vehicle control systems, along with driver input, to

provide the best performance for all terrains.

Selec-Terrain Switch

Selec-Terrain consists of the following positions:



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).

STARTING AND OPERATING

107



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 equipped with

air suspension, the level will change to Normal

Ride Height (NRH) unless in the Off-Road 1

(OR1) or Off-Road 2 (OR2) position, the height of

OR1 or OR2 will be maintained.



SAND – Off-road calibration for use on low trac

tion surfaces such as sand or wet grass. Drive

line 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 default ride

height for SAND is Normal Ride Height (NRH).



MUD – Off-road calibration for use on low trac

tion surfaces such as mud. Driveline is maxi

mized for traction. Some binding may be felt on

less forgiving surfaces. The electronic brake

controls are set to limit traction control manage

ment of throttle and wheel spin. If equipped with

air suspension, the level will change to OR1.



ROCK – Off-road calibration is only available in

4WD LOW range. The vehicle is raised (if

equipped with Air Suspension) for improved

ground clearance. 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. If the Selec-Terrain switch is in

ROCK mode, and the transfer case is switched

out of 4WD LOW, the Selec-Terrain system will

return to AUTO.

STARTING AND OPERATING

CRUISE CONTROL SYSTEMS — IF EQUIPPED

Your vehicle may be equipped with the Cruise

Control system, or the Adaptive Cruise Control

(ACC) system:



Cruise Control will keep your vehicle at a

constant preset speed.



Adaptive Cruise Control (ACC) will adjust the

vehicle speed up to the preset speed to main

tain a distance with the vehicle ahead.

NOTE:



Fixed Speed Cruise Control (ACC not enabled)

will not detect vehicles directly ahead of you.

Always be aware of the feature selected.



Only one Cruise Control feature can operate at a

time. For example, if Fixed Speed Cruise Control

is enabled, Adaptive Cruise Control will be

unavailable, and vice versa.

RUISE

RUISE

ONTROL

(ACC)

Adaptive Cruise Control (ACC) increases the driving

convenience provided by Cruise Control while

traveling on highways and major roadways.

However, it is not a safety system and not designed

to prevent collisions. The Cruise Control function

performs differently

page 110.

ACC will allow you to keep Cruise Control engaged

in light to moderate traffic conditions without the

constant need to reset your Cruise Control. ACC

utilizes a radar sensor and a forward-facing

camera designed to detect a vehicle directly ahead

of you to maintain a set speed.

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 modifica

tions to the vehicle will affect the performance

of the Adaptive Cruise Control and Forward Colli

sion 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 321.

WARNING!



Adaptive Cruise Control (ACC) is a conve

nience system. It is not a substitute for active

driver involvement. It is always the driver’s

responsibility to be attentive of road, traffic,

and weather conditions, vehicle speed,

distance to the vehicle ahead; and, most

importantly, brake operation to ensure safe

operation of the vehicle under all road condi

tions. Your complete attention is always

required while driving to maintain safe control

of your vehicle. Failure to follow these warn

ings can result in a collision and death or

serious personal injury.



The ACC system:



Does not react to pedestrians, oncoming

vehicles, and stationary objects (e.g., a

stopped vehicle in a traffic jam or a

disabled vehicle).



Cannot take street, traffic, and weather

conditions into account, and may be

limited upon adverse sight distance condi

tions.



Does not always fully recognize complex

driving conditions, which can result in

wrong or missing distance warnings.



Will bring the vehicle to a complete stop

while following a target vehicle and hold

the vehicle for two seconds in the stop

position. If the target vehicle does not

start moving within two seconds the ACC

system will display a message that the

system will release the brakes and that

the brakes must be applied manually.

An audible chime will sound when the

brakes are released.

You should switch off the ACC system:



When driving in fog, heavy rain, heavy snow,

sleet, heavy traffic, and complex driving situa

tions (i.e., in highway construction zones).



When entering a turn lane or highway

off-ramp; when driving on roads that are

winding, icy, snow-covered, slippery, or have

steep uphill or downhill slopes.



When towing a trailer up or down steep slopes.



When circumstances do not allow safe driving

at a constant speed.

Resume can be used at any speed above 0 mph

(0 km/h) when ACC is active.

NOTE:



While in ACC mode when the vehicle comes to a

complete stop longer than two seconds, the

system will cancel. The driver will have to apply

the brakes to keep the vehicle at a standstill.



ACC cannot be resumed if there is a stationary

vehicle in front of your vehicle in close proximity.

To Vary The Speed Setting

To Increase Or Decrease The Set Speed
While ACC is set, you can increase speed by

pushing the SET (+) button, or decrease speed by

pushing the SET (-) button.
U.S. Speed (mph)



Pushing the SET (+), or SET (-) button once will

result in a 1 mph speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 mph.



If the button is continually pushed, the set

speed will continue to adjust in 5 mph incre

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

Metric Speed (km/h)



Pushing the SET (+), or SET (-) button once will

result in a 1 km/h speed adjustment. Each

subsequent tap of the button results in an

adjustment of 1 km/h.



If the button is continually pushed, the set

speed will continue to adjust in 10 km/h incre

ments until the button is released. The new set

speed is reflected in the instrument cluster

display.

NOTE:

When you override and push the SET (+) button or

SET (-) buttons, the new set speed will be the

current speed of the vehicle.
When ACC Is Active:



When you use the SET (-) button to decelerate, if

the engine’s braking power does not slow the

vehicle sufficiently to reach the set speed, the

brake system will automatically slow the

vehicle.



The ACC system applies the brake down to a full

stop when following the vehicle in front. If your

vehicle follows the vehicle in front to a standstill,

your vehicle will release the brakes two seconds

after coming to a full stop.

WARNING!

The Resume function should only be used if

traffic and road conditions permit. Resuming a

set speed that is too high or too low for

prevailing traffic and road conditions could

cause the vehicle to accelerate or decelerate too

sharply for safe operation. Failure to follow these

warnings can result in a collision and death or

serious personal injury.

116

STARTING AND OPERATING



The ACC system maintains set speed when

driving uphill and downhill. However, a slight

speed change on moderate hills is normal. In

addition, downshifting may occur while climbing

uphill or descending downhill. This is normal

operation and necessary to maintain set speed.

When driving uphill and downhill, the ACC

system will cancel if the braking temperature

exceeds normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for ACC can be set

by varying the distance setting between four bars

(longest), three bars (long), two bars (medium) and

one bar (short). Using this distance setting and the

vehicle speed, ACC calculates and sets the

distance to the vehicle ahead. This distance

setting displays in the instrument cluster display.

Distance Settings

To increase the distance setting, push the

Distance Increase button and release. Each time

the button is pushed, the distance setting

increases by one bar (longer).
To decrease the distance setting, push the

Distance Decrease button and release. Each time

the button is pushed, the distance setting

decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will

maintain the set speed. If a slower moving vehicle

is detected in the same lane, the instrument

cluster display will show the ACC Set With Target

Detected Light. The system will then adjust vehicle

speed automatically to maintain the distance

setting, regardless of the set speed.
The vehicle will then maintain the distance set by

the driver until:



The vehicle ahead accelerates to a speed above

the set speed.



The vehicle ahead moves out of your lane or

view of the sensor.



The distance setting is changed.



The system disengages

page 113.

The maximum braking applied by ACC is limited;

however, the driver can always apply the brakes

manually, if necessary.

NOTE:

The brake lights will illuminate whenever the ACC

system applies the brakes.
A Proximity Warning will alert the driver if ACC

predicts that its maximum braking level is not

sufficient to maintain the set distance. If this occurs,

a visual alert “BRAKE!” will flash in the instrument

cluster display and a chime will sound while ACC

continues to apply its maximum braking force.

NOTE:

The “BRAKE!” screen in the instrument cluster

display is a warning for the driver to take action

and does not necessarily mean that the Forward

Collision Warning system is applying the brakes

autonomously.

STARTING AND OPERATING

117

Overtake Aid

When driving with ACC engaged and following a

vehicle, the system will provide an additional

acceleration up to the ACC set speed to assist in

passing the vehicle. This additional acceleration is

triggered when the driver utilizes the left turn

signal and will only be active when passing on the

left hand side.

ACC Operation At Stop

If the ACC system brings your vehicle to a standstill

while following a vehicle ahead, your vehicle will

resume motion, without any driver interaction, if

the vehicle ahead starts moving within two

seconds of your vehicle coming to a standstill.
If the vehicle in front does not start moving within

two seconds of your vehicle coming to a standstill,

the ACC with Stop system will cancel and the

brakes will release. A cancel message will display

on the instrument cluster display and produce a

warning chime. The driver must now manually

operate the vehicle’s accelerator and brakes.
While ACC with Stop is holding your vehicle at a

standstill, if the driver seat belt is unbuckled or the

driver door is opened, the ACC with Stop system

will cancel and the brakes will release. A cancel

message will display on the instrument cluster

display and produce a warning chime. The driver

must now manually operate the vehicle’s

accelerator and brakes.

Display Warnings And Maintenance

“WIPE FRONT RADAR SENSOR IN FRONT OF

VEHICLE” WARNING

The “ACC/FCW Unavailable Wipe Front Radar

Sensor” warning will display and a chime will

sound when conditions temporarily limit system

performance.
This most often occurs at times of poor visibility,

such as in snow or heavy rain. The ACC system may

also become temporarily blinded due to

obstructions, such as mud, dirt or ice. In these

cases, the instrument cluster display will display

the above message and the system will deactivate.
This message can sometimes be displayed while

driving in highly reflective areas (i.e. ice and snow,

or tunnels with reflective tiles). The ACC system will

recover after the vehicle has left these areas.

Under rare conditions, when the radar is not

tracking any vehicles or objects in its path this

warning may temporarily occur.

NOTE:

If the “ACC/FCW Unavailable Wipe Front Radar

Sensor” warning is active, Fixed Speed Cruise

Control is still available.
If weather conditions are not a factor, the driver

should examine the sensor. It may require cleaning

or removal of an obstruction. The sensor is located

in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is

important to note the following maintenance

items:



Always keep the sensor clean. Carefully wipe the

sensor lens with a soft cloth. Be cautious not to

damage the sensor lens.



Do not remove any screws from the sensor.

Doing so could cause an ACC system malfunc

tion or failure and require a sensor realignment.



If the sensor or front end of the vehicle is

damaged due to a collision, see an authorized

dealer for service.



Do not attach or install any accessories near the

sensor, including transparent material or after

market grilles. Doing so could cause an ACC

system failure or malfunction.

When the condition that deactivated the system is

no longer present, the system will return to the

“Adaptive Cruise Control Off” state and will resume

function by simply reactivating it.

WARNING!

When the ACC system is resumed, the driver

must ensure that there are no pedestrians,

vehicles or objects in the path of the vehicle.

Failure to follow these warnings can result in a

collision and death or serious personal injury.

118

STARTING AND OPERATING

NOTE:



If the “ACC/FCW Unavailable Wipe Front Radar

Sensor” message occurs frequently (e.g. more

than once on every trip) without any snow, rain,

mud, or other obstruction, have the radar

sensor realigned at an authorized dealer.



Installing a snow plow, front-end protector, an

aftermarket grille or modifying the grille is not

recommended. Doing so may block the sensor

and inhibit ACC/FCW operation.

“CLEAN FRONT WINDSHIELD” WARNING

The “ACC/FCW Limited Functionality Clean Front

Windshield” warning will display and a chime will

sound when conditions temporarily limit system

performance. This most often occurs at times of

poor visibility, such as in snow or heavy rain and

fog. The ACC system may also become temporarily

blinded due to obstructions, such as mud, dirt, or

ice on windshield and fog on the inside of glass. In

these cases, the instrument cluster display will

display “ACC/FCW Limited Functionality Clean

Front Windshield” and the system will have

degraded performance.
This message can sometimes be displayed while

driving in adverse weather conditions. The ACC/

FCW system will recover after the vehicle has left

these areas. Under rare conditions, when the

camera is not tracking any vehicles or objects in its

path this warning may temporarily occur.

If weather conditions are not a factor, the driver

should examine the windshield and the camera

located on the back side of the inside rearview

mirror. They may require cleaning or removal of an

obstruction.
When the condition that created limited

functionality is no longer present, the system will

return to full functionality.

NOTE:

If the “ACC/FCW Limited Functionality Clean Front

Windshield” message occurs frequently (e.g. more

than once on every trip) without any snow, rain,

mud, or other obstruction, have the windshield and

forward-facing camera inspected at an authorized

dealer.

SERVICE ACC/FCW WARNING

If the system turns off, and the instrument cluster

displays “ACC/FCW Unavailable Service Required”

or “Cruise/FCW Unavailable Service Required”,

there may be an internal system fault or a

temporary malfunction that limits ACC

functionality. Although the vehicle is still drivable

under normal conditions, ACC will be temporarily

unavailable. If this occurs, try activating ACC again

later, following an ignition cycle. If the problem

persists, see an authorized dealer.

Precautions While Driving With ACC

In certain driving situations, ACC may have

detection issues. In these cases, ACC may brake

late or unexpectedly. The driver needs to stay alert

and may need to intervene. The following are

examples of these types of situations:

TOWING A TRAILER

Towing a trailer is not recommended when using ACC.

OFFSET DRIVING

ACC may not detect a vehicle in the same lane that

is offset from your direct line of travel, or a vehicle

merging in from a side lane. There may not be

sufficient distance to the vehicle ahead. The offset

vehicle may move in and out of the line of travel,

which can cause your vehicle to brake or

accelerate unexpectedly.

Offset Driving Condition Example

STARTING AND OPERATING

119

TURNS AND BENDS

When driving on a curve with ACC engaged, the

system may increase or decrease the vehicle

speed for stability, with no vehicle ahead detected.

Once the vehicle is out of the curve the system will

resume your original set speed. This is a part of

normal ACC system functionality.

NOTE:

On tight turns ACC performance may be limited.

USING ACC ON HILLS

ACC performance may be limited when driving on

hills. ACC may not detect a vehicle in your lane

depending on the speed, vehicle load, traffic

conditions, and the steepness of the hill.

ACC Hill Example

LANE CHANGING

ACC may not detect a vehicle until it is completely

in the lane in which you are traveling. In the

following lane changing example, ACC has not yet

detected the vehicle changing lanes and it may not

detect the vehicle until it's too late for the ACC

system to take action. ACC may not detect a

vehicle until it is completely in the lane. There may

not be sufficient distance to the lane-changing

vehicle. Always be attentive and ready to apply the

brakes if necessary.

Lane Changing Example

NARROW VEHICLES

Some narrow vehicles traveling near the outer

edges of the lane or edging into the lane are not

detected until they have moved fully into the lane.

There may not be sufficient distance to the vehicle

ahead.

Narrow Vehicle Example

120

STARTING AND OPERATING

STATIONARY OBJECTS AND VEHICLES

ACC does not react to stationary objects or

vehicles. For example, ACC will not react in

situations where the vehicle you are following exits

your lane and the vehicle ahead is stopped in your

lane. It will consider this stopped vehicle a

stationary object as it did not previously detect

movement from it. Always be attentive and ready

to apply the brakes if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE FRONT/REAR PARK ASSIST

SYSTEM — IF EQUIPPED

The ParkSense Park Assist system provides visual

and audible indications of the distance between

the rear, and if equipped, the front fascia/bumper

and a detected obstacle when backing up or

moving forward (e.g. during a parking maneuver).

The vehicle brakes may be automatically applied

and released when performing a reverse parking

maneuver if the system detects a possible collision

with an obstacle.

NOTE:



The driver can disable the automatic braking

function by turning ParkSense off via the Park

Sense switch. The driver can also override auto

matic braking by shifting out of REVERSE or by

pressing the gas pedal over 90% of its capacity

during the braking event.



Automatic brakes are not available if ESC is not

available.



Automatic brakes are not available if the vehicle

is in 4WD Low.



Automatic brakes will not be available if there is

a faulted condition detected with the ParkSense

Park Assist system or the Braking System

Module.



The automatic braking function may only be

applied if the vehicle deceleration is not enough

to avoid colliding with a detected obstacle.



The automatic braking function may not be

applied fast enough for obstacles that move

toward the rear of the vehicle from the left and/

or right sides.



The automatic braking function can be

enabled/disabled from the Customer Program

mable Features section of the Uconnect system.



ParkSense will retain its last known configura

tion state for the automatic braking function

through ignition cycles.

STARTING AND OPERATING

121

The automatic braking function is intended to

assist the driver in avoiding possible collisions with

detected obstacles when backing up in REVERSE

gear.

NOTE:



The system is designed to assist the driver and

not to substitute the driver.



The driver must stay in full control of the

vehicle's acceleration and braking and is

responsible for the vehicle's movements.

For limitations of this system and

recommendations, see

page 125.

ParkSense will retain the last system state

(enabled or disabled) from the last ignition cycle

when the ignition is changed to the ON/RUN

position.

ParkSense can be active only when the gear

selector is in REVERSE or DRIVE. If ParkSense is

enabled at one of these gear selector positions,

the system will remain active until the vehicle

speed is increased to approximately 7 mph

(11 km/h) or above. The system will become active

again if the vehicle speed is decreased to speeds

less than approximately 6 mph (9 km/h). A display

warning will appear in the instrument cluster

display if the vehicle is in REVERSE and the speed

exceeds 7 mph (11 km/h).

ARK

ENSE

ENSORS

The six ParkSense sensors (there may only be four,

depending on the vehicle options), located in the

rear fascia/bumper, and the six ParkSense

sensors located in the front fascia/bumper

(if equipped), monitor the area in front and behind

the vehicle that is within the sensors’ field of view.

The front sensors detect obstacles from

approximately 12 inches (30 cm) up to 47 inches

(120 cm) from the front fascia/bumper. The rear

sensors can detect obstacles from approximately

12 inches (30 cm) up to 79 inches (200 cm) from

the rear fascia/bumper. These distances depend

on the location, type and orientation of the

obstacle in the horizontal direction.

ARK

ENSE

ISPLAY

The warning display will turn on indicating the

system status when the vehicle is in REVERSE or

when the vehicle is in DRIVE and an obstacle has

been detected.
The system will indicate a detected obstacle by

showing a single arc in the left and/or right front or

rear regions based on the object’s distance and

location relative to the vehicle.
If an object is detected in the left and/or right rear

region, the display will show a single arc in the left

and/or right rear region and the system will

produce a tone. As the vehicle moves closer to the

object, the display will show the single arc moving

closer to the vehicle and the tone will change from

a single 1/2 second tone to slow, to fast, to

continuous.
