STARTING AND OPERATING

(Continued)

CRUISE CONTROL SYSTEMS

Your vehicle is equipped with the Adaptive Cruise

Control (ACC) system which will adjust the vehicle

speed up to the preset speed to maintain a

distance with the vehicle ahead.

NOTE:

In vehicles NOT equipped with the Active Driving

Assist (ADA) system:



Fixed Speed Cruise Control can be used when

ACC is not enabled, and functions as normal

cruise control.



Fixed Speed Cruise Control will not detect vehi

cles 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.

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.

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.



In vehicles NOT equipped with the Active Driving

Assist system, Fixed Speed Cruise Control (ACC

not enabled) will not detect vehicles directly

ahead of you. Always be aware of the feature

selected

page 408.

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

stationary 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 conditions.



Does not always fully recognize complex

driving conditions, which can result in

wrong or missing distance warnings.

20 mph (32 km/h).

NOTE:

Fixed Speed Cruise Control cannot be set below

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.

WARNING!

Leaving the Adaptive Cruise Control (ACC)

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 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.

STARTING AND OPERATING

145

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.

vehicle in front of your vehicle in close proximity.

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.

146

STARTING AND OPERATING

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 (-) button, 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 decelerates the vehicle to a full

stop when following the 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).

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

STARTING AND OPERATING

147

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 144.

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.

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

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 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:



If your vehicle is at a standstill for longer than

two seconds, the system will hold brake pres

sure for up to 10 minutes. If no driver action is

taken after the 10 minutes, the Electric Park

Brake will be applied and the ACC system will

cancel.



While ACC is holding your vehicle at a standstill

(or the vehicle is traveling below 3 mph

(5 km/h), and the driver seat belt is unbuckled

or the driver door is opened, the Electric Park

Brake will be applied and the ACC system will

cancel.

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.

148

STARTING AND OPERATING

Display Warnings And Maintenance

“WIPE FRONT RADAR SENSOR IN FRONT OF

VEHICLE” WARNING

The “ACC 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 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 your 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.

NOTE:



If the “ACC 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 snowplow, front-end protector, an

aftermarket grille or modifying the grille is not

recommended. Doing so may block the sensor

and inhibit ACC operation.

“CLEAN FRONT WINDSHIELD” WARNING

The “ACC 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 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

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.

STARTING AND OPERATING

149

When the condition that created limited

functionality is no longer present, the system will

return to full functionality.

NOTE:

If the “ACC Limited Functionality Clean Front Wind

shield” 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 WARNING

If the system turns off, and the instrument cluster

display reads “ACC Unavailable Service Required”

or “Cruise 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

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.

150

STARTING AND OPERATING

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 is 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

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

STARTING AND OPERATING

151

TRAFFIC SIGN ASSIST SYSTEM —

IF EQUIPPED

The Traffic Sign Assist (TSA) system uses a camera

mounted on the windshield, as well as map data

when the vehicle is equipped with Navigation, to

detect recognizable road signs such as:



Speed limits



School zones



No passing zones

NOTE:



The TSA system will automatically display the

detected road sign using the unit of measure

ment (mph or km/h) selected within the instru

ment cluster display.



If no speed limit signs are detected, the system

will revert to the speed limit signs that are

stored in the Navigation system.



The system always checks the traffic signs indi

cating the current speed limit. The system is

able to recognize and display up to two different

road signs in the instrument cluster display.

These road signs can be found on the Driver

Assist page.

CTIVATION

EACTIVATION

The TSA System can be enabled/disabled within

the Uconnect system through the Safety/Driver

Assistance menu. System ON is signaled by road

signs shown on the instrument cluster display.

When Visual is selected, the system will alert the

driver when the current speed of the vehicle

exceeds the detected speed limit by showing a

graphic in the instrument cluster display.

Visual + Chime
When Visual + Chime is selected, the system will

alert the driver when the current speed of the

vehicle exceeds the detected speed limit by

showing a graphic in the instrument cluster

display, and by sounding an audible alert. The

audible alert will last for 10 seconds, and the

visual alert will remain on as long as the vehicle is

exceeding the speed limit.
TSA Off
When the TSA system is turned off, the system will

not show any traffic signs (unless selected in the

HOME screen, which will show detected speed

limit signs), and no alerts will be issued to the

driver.

ACTIVE DRIVING ASSIST SYSTEM —

IF EQUIPPED

PERATION

The Active Driving Assist (ADA) system is combined

with the Adaptive Cruise Control (ACC) system, and

centers the vehicle in the driving lane while

traveling at speeds up to 90 mph (145 km/h).
For ACC system operating instructions and system

limitations, see

page 142.

NOTE:



The driver should always obey traffic laws and

speed limits. Never drive above applicable

speed limit restrictions.

1 — Current Speed Limit With Supplemental Infor

mation (School Zone)
2 — Next Speed Limit Detected
3 — No Passing Zone Detected

CAUTION!



Traffic Sign Assist is designed to assist the

driver and not to substitute the driver. It is the

driver’s responsibility to continue to monitor

the vehicle speed.



Functionality may be limited or the system

may not work if the sensor is obstructed.



The system may have limited operation or not

work at all in weather conditions such as

heavy rain, hail, and thick fog. Strong light

contrasts can influence the recognition capa

bility of the sensor.



The area surrounding the sensor must not be

covered with stickers or any other object.



Do not tamper or perform any operations in

the area of the windshield glass directly

surrounding the sensor.



Clean foreign matters such as bird droppings,

insects, snow or ice on the windshield. For

glass cleaning recommendations, see

page 395.

CAUTION!

STARTING AND OPERATING

153



The driver can override ADA at any time by

braking, accelerating, or steering the vehicle.

Just like ACC, ADA will maintain a set speed as long

as the set distance between your vehicle and the

vehicle in front is maintained. ADA will also keep

your vehicle centered between the lane lines, and

monitor for other vehicles in adjacent lanes by

utilizing the Blind Spot Monitoring sensors.
Two types of Active Driving Assist systems are

available:



Base ADA system



Hands-Free ADA system

Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the

steering wheel to measure driver attentiveness,

and requires that the driver have their hands on

the steering wheel at all times.
The system will generally aim to keep the vehicle

centered in the lane, but when the driver turns the

steering wheel (e.g. to move farther away from a

large vehicle in an adjacent lane) the system will

reduce its control and enter "co-steering" mode.

While in co-steering mode, the system will provide

reduced assistance and allow the driver to control

the path of the vehicle. Once the driver stops

providing input to the steering wheel, the system

will require a few seconds to fully resume lane

centering assistance, especially during curves.

Hands-Free Active Driving Assist System —

If Equipped
The Hands-Free ADA system uses sensors within

the steering wheel and a driver monitoring camera

located on top of the steering column to monitor

driver attentiveness. The Hands-Free ADA system

allows the driver to remove their hands from the

steering wheel when engaged, but requires that

the driver continue to pay attention to the road.
The Hands-Free ADA system will also change lanes

when a turn signal is activated if the adjacent lane

in the direction indicated is clear of another

vehicle, and lane markings are detected (noted by

a dashed line in the direction of the available lane

change). The system uses sensors, including Blind

Spot Monitoring (BSM) sensors, to determine if a

lane change is possible. If the assisted lane

change is in progress, a green arrow will appear. If

a lane change is requested but the direction

indicated is not possible, a yellow arrow will

appear. Once conditions are clear, the arrow will

turn green and the assisted lane change will begin.
Additionally, Hands-Free ADA will slow the vehicle

down when approaching and going through sharp

curves.

Assisted Lane Change (Green Left Arrow)

Extended Auto Resume
If equipped with Hands-Free ADA and the system

brings your vehicle to a stop while following the

vehicle ahead, your vehicle will automatically

resume driving without driver input when the path

in front of the vehicle is clear and the driver is

attentive. The path in front of the vehicle is

determined to be clear based on the forward facing

camera, front radars, and front ultrasonic sensors.

WARNING!

The driver is always responsible for determining

if a lane change is safe. Failure to follow this

warning can result in a collision and death or

serious personal injury.

STARTING AND OPERATING

(Continued)

If the vehicle in front does not start moving after

10 minutes, the Electric Park Brake (EPB) will be

applied and the system will cancel.
NOTE:



The Hands-Free Active Driving Assist system is

only available on approved compatible road

ways. Please consult the Jeep® website for

further details on compatible roadways.



The Hands-Free Active Driving Assist system

requires an active subscription through the

Jeep® Connect (Uconnect Connected Services)

package. If the ADA on/off button is pushed

without an active subscription, the instrument

cluster display will show the message “Active

Driving Assist Unavailable Update Subscrip

tion”. Refer to the Uconnect Owner’s Manual

Supplement for further information.



If previously disabled, activating the Hands-Free

Active Driving Assist system will also activate

the Forward Collision Warning and Pedestrian

Emergency Braking systems

page 261.



If the vehicle is equipped with the Jeep®

Connect (Uconnect Connected Services)

package, additional data may be collected

through the Jeep® Connect (Uconnect

Connected Services) system. This includes

information about the vehicle’s operation, a

collision involving the vehicle, the use of the

vehicle and its features, and in certain situa

tions, the location and approximate GPS speed

of the vehicle. Refer to the Uconnect Owner’s

Manual Supplement for Terms and Conditions

and Privacy Statements.



The driver monitoring camera may record

images of the driver during certain crash, or

near crash-like situations. To retrieve the

images recorded by the camera, special equip

ment is required and access to the vehicle or

the camera is needed.



Vehicle data may be read from the Hands-Free

ADA system with special equipment and access

to the vehicle or the Event Data Recorder (EDR).

WARNING!

The Active Driving Assist (ADA) system is a

convenience system. It is not a substitute for

active driver involvement. It is always the driver’s

responsibility to be attentive of road traffic,

weather conditions, vehicle speed, distance to

the vehicle ahead, position in the lane compared

to other vehicles, and brake operation to ensure

safe operation of the vehicle under all road

conditions. Your complete attention is always

required while driving to maintain safe control of

your vehicle. Failure to follow these warnings can

result in a collision and death or serious

personal injury.

Some states and local laws may require hands

to be kept on the steering wheel at all times. For

vehicles equipped with the Hands-Free ADA

system, ONLY remove your hands from the

steering wheel if the Hands-Free system is

engaged, it is safe to do so, and it is permitted by

state and local laws.
You should turn off the Active Driving Assist

systems:



When driving in complex driving situations

(e.g. urban environments, construction zones,

etc.), adverse weather or low visibility condi

tions (e.g. rain, snow, fog, sleet, dust), or

adverse road conditions (e.g. heavy traffic,

worn or missing lane markings, etc.).



When entering a highway on-ramp or exiting

an off-ramp.



When driving on roads that are icy, snow

covered, or slippery.



When driving during difficult or uncertain

conditions.
