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:



In vehicles equipped with ACC, if ACC is not

enabled, Fixed Speed Cruise Control 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

ONTROL

When engaged, the Cruise Control takes over

accelerator operations at speeds greater than

20 mph (32 km/h).
The Cruise Control buttons are located on the right

side of the steering wheel.

WARNING!

Cruise Control can be dangerous where the

system cannot maintain a constant speed. Your

vehicle could go too fast for the conditions, and

you could lose control and have an accident. Do

not use Cruise Control in heavy traffic or on

roads that are winding, icy, snow-covered or

slippery.

WARNING!

Leaving the Cruise Control system on when not

in use is dangerous. You could accidentally set

the system or cause it to go faster than you

want. You could lose control and have an

accident. Always leave the system off when you

are not using it.

108

STARTING AND OPERATING

To Set A Desired Speed

Turn the Cruise Control on. When the vehicle has

reached the desired speed, push and release the

SET (+) or SET (-) button. Release the accelerator

and the vehicle will operate at the selected speed.

Once a speed has been set, a message “CRUISE

CONTROL SET TO MPH (km/h)” will appear

indicating the set speed. A cruise indicator lamp,

along with set speed will also appear and stay on

in the instrument cluster when the speed is set.

To Vary The Speed Setting

To Increase Or Decrease The Set Speed
When the Cruise Control 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 until the button is released,

then the new set speed will be established.

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

If the button is continually pushed, the set speed

will continue to adjust until the button is released,

then the new set speed will be established.

To Accelerate For Passing

While the Cruise Control is set, press the

accelerator to pass as you would normally. When

the pedal is released, the vehicle will return to the

set speed.

USING CRUISE CONTROL ON HILLS

The transmission may downshift on hills to

maintain the vehicle set speed.
The Cruise Control system maintains speed up and

down hills. A slight speed change on moderate hills

is normal. On steep hills, a greater speed loss or

gain may occur so it may be preferable to drive

without Cruise Control.

To Resume Speed

To resume a previously set speed, push the RES

button and release. Resume can be used at any

speed above 20 mph (32 km/h).

To Deactivate

A tap on the brake pedal, pushing the CANC button,

Control system without erasing the set speed from

memory.
The following conditions will also deactivate the

Cruise Control without erasing the set speed from

memory:



Vehicle parking brake is applied



Stability event occurs



Gear selector is moved out of DRIVE



Engine overspeed occurs

Pushing the on/off button or placing the ignition in

the OFF position, will erase the set speed from

memory.

WARNING!

Cruise Control can be dangerous where the sys

tem cannot maintain a constant speed. Your vehi

cle could go too fast for the conditions, and you

could lose control and have an accident. Do not

use Cruise Control in heavy traffic or on roads

that are winding, icy, snow-covered or slippery.

DAPTIVE

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 107.

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.

NOTE:



If the ACC sensor detects a vehicle ahead, ACC

will apply limited braking or acceleration (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 will not detect vehi

cles directly ahead of you. Always be aware of

the feature selected

page 308.

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

and hold the vehicle in the stop position

for approximately three minutes when

following a vehicle ahead. If the vehicle

ahead does not start moving within three

minutes, the parking brake will be acti

vated, and the ACC system will be

cancelled.



You should switch off the ACC system:



When driving in fog, heavy rain, heavy

snow, sleet, heavy traffic, and complex

driving situations (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.

20 mph (32 km/h).
If either system is set when the vehicle speed is

above 20 mph (32 km/h), the set speed shall be

the current speed of the vehicle.

NOTE:



Keeping your foot on the accelerator pedal can

cause the vehicle to continue to accelerate

beyond the set speed. If this occurs, the

message “DRIVER OVERRIDE” will display in the

instrument cluster display.



If you continue to accelerate beyond the set

speed while ACC is enabled, the system will not

be controlling the distance between your vehicle

and the vehicle ahead. The vehicle speed will

only be determined by the position of the accel

erator pedal.

system on when not in use is dangerous. You

could accidentally set the system or cause it to

go faster than you want. You could lose control

and have a collision. Always leave the system off

when you are not using it.

WARNING!

In the Fixed Speed Cruise Control mode, the

system will not react to vehicles ahead. In

addition, the proximity warning does not activate

and no alarm will sound even if you are too close

to the vehicle ahead since neither the presence

of the vehicle ahead nor the vehicle-to-vehicle

distance is detected. Be sure to maintain a safe

distance between your vehicle and the vehicle

ahead. Always be aware which mode is selected.

112

STARTING AND OPERATING

The following conditions will only cancel the ACC

system:



Driver seat belt is unbuckled at low speeds



(resume) button and remove your foot from the

accelerator pedal. The instrument cluster display

will show the last set speed.
Resume can be used at any speed above 20 mph

(32 km/h) when only Fixed Speed Cruise Control is

being used.
Resume can be used at any speed above 0 mph

(0 km/h) when ACC is active.

NOTE:



If your vehicle stays at standstill for longer than

two seconds, then the driver will either have to

push the RES (resume) button, or apply the

accelerator pedal to reengage the Adaptive

Cruise Control (ACC) to the existing set speed.



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
After setting a speed, you can increase the set

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.

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.

STARTING AND OPERATING

113

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 decelerates the vehicle to a full

stop when following a vehicle in front. If your

vehicle follows the vehicle in front to a standstill,

after two seconds the driver will either have to

push the RES (resume) button, or apply the

accelerator pedal to reengage the ACC to the

existing set speed.



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 appears 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 Indicator Light, and the system will adjust

the vehicle speed automatically to maintain the

distance setting, regardless of the set speed.
The vehicle will then maintain the set distance 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 111.

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

capacity.

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.

114

STARTING AND OPERATING

Overtake Aid

When driving with Adaptive Cruise Control (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

In the event that the ACC system brings your

vehicle to a standstill while following the vehicle in

front, if the vehicle in front starts moving within two

seconds of your vehicle coming to a standstill, your

vehicle will resume motion without the need for

any driver action.
If the vehicle in front does not start moving within

two seconds of your vehicle coming to a standstill,

the driver will either have to push the RES (resume)

button, or apply the accelerator pedal to reengage

the ACC to the existing set speed.

NOTE:

After the ACC system holds your vehicle at a stand

still for approximately three consecutive minutes,

the parking brake will be activated, and the ACC

system will be cancelled.
While ACC is holding your vehicle at a standstill, if

the driver seat belt is unbuckled or the driver door

is opened, the parking brake will be activated, and

the ACC system will be cancelled.

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.

STARTING AND OPERATING

115

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

read “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

display reads “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

116

STARTING AND OPERATING

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 lane

changing example below, 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.

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 changing the gear or by

pressing the gas pedal over 90% of its capacity

during the braking event.



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.

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.

118

STARTING AND OPERATING

For limitations of this system, precautions, and

recommendations, see

page 122.

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 (four when vehicle is

not equipped with front sensors), located in the

rear fascia/bumper, and the six ParkSense

sensors located in the front fascia/bumper,

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.

120

STARTING AND OPERATING

The vehicle is close to the obstacle when the instrument cluster display shows one flashing arc and sounds a continuous tone. The following chart shows the

warning alert operation when the system is detecting an obstacle:

NOTE:

ParkSense will reduce the volume of the radio, if on, when the system is sounding an audio tone.
