the ACC system.

Adaptive Cruise Control Buttons

Adaptive Cruise Control (ACC) Menu

The instrument cluster display will show the current ACC

system settings. The information it displays depends on

ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button until

one of the following appears in the instrument cluster

display:

WARNING!



Adaptive Cruise Control (ACC) is a convenience

system. It is not a substitute for active driver involve

ment. 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 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 colli

sion and death or serious personal injury.



The ACC system:



Does not react to pedestrians, oncoming vehi

cles, and stationary objects (e.g., a stopped

vehicle in a traffic jam or a disabled vehicle).



Cannot take street, traffic, and weather condi

tions 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.



On vehicles with an automatic transmission, will

bring the vehicle to a complete stop while

following a vehicle ahead and hold the vehicle

for two seconds in the stop position. If the

vehicle ahead 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 not utilize 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.

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

155

If ACC is set when the vehicle speed is below 20 mph

(32 km/h), the set speed will default to 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.
On vehicles equipped with a manual transmission, the

ACC system cannot be set when the vehicle speed is below

20 mph (32 km/h) or when the vehicle is in FIRST gear.

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

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.

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 condi

tions could cause the vehicle to accelerate or deceler

ate too sharply for safe operation. Failure to follow

these warnings can result in a collision and death or

serious personal injury.

156

STARTING AND OPERATING

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 increments until the button

is released. The new set speed is reflected in the instru

ment 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 increments 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 suffi

ciently 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.



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

Setting 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

Setting 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 displays the ACC Set

With Target 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 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 154

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

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

STARTING AND OPERATING

157

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 neces

sarily mean that the Forward Collision Warning system is

applying the brakes autonomously.

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 A Stop (Automatic

Transmission Only)

In the event that the ACC system brings your vehicle to a

standstill while following a target vehicle, your vehicle will

resume motion without the need for any driver action if the

target vehicle starts moving within two seconds of your

vehicle coming to a standstill.
If the target vehicle 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. Driver intervention

will be required at this moment.
While ACC with Stop is holding your vehicle at a standstill,

if the driver seatbelt 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.

Driver intervention will be required at this moment.

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 “ACC/FCW Unavailable Wipe Front Radar Sensor”

and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”

message can sometimes be displayed while driving in

highly reflective areas (i.e. tunnels with reflective tiles, or

ice and snow). 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 malfunction 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 aftermarket

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/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.

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.

158

STARTING AND OPERATING

“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.
The “ACC/FCW Limited Functionality Clean Front

Windshield” 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 rear view 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 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/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

TURNS AND BENDS

When driving on a curve with ACC engaged, the system

may decrease the vehicle speed and acceleration for

stability reasons, with no vehicle in front 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.

STARTING AND OPERATING

159

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

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

160

STARTING AND OPERATING

PARKSENSE REAR PARK ASSIST —

IF EQUIPPED

The ParkSense Rear Park Assist system provides visual

and audible indications of the distance between the rear

fascia/bumper and a detected obstacle when backing up

(e.g. during a parking maneuver). For limitations of this

system and recommendations, see

page 163.

ParkSense will retain the last system state (enabled or

disabled) from the last ignition cycle when the ignition is

placed in the ON/RUN position.
ParkSense can be active only when the gear selector is in

REVERSE. If ParkSense is enabled at this gear selector

position, the system will remain active until the vehicle

speed is increased to approximately 7 mph (11 km/h) or

above. When in REVERSE and above the system's

operating speed, a warning will appear within the

instrument cluster display indicating the vehicle speed is

too fast. The system will become active again if the vehicle

speed is decreased to speeds less than approximately

6 mph (9 km/h).

ARK

ENSE

ENSORS

The four ParkSense sensors, located in the rear fascia/

bumper, monitor the area behind the vehicle that is within

the sensors’ field of view. The sensors can detect

obstacles from approximately 12 inches (30 cm) up to

79 inches (200 cm) from the rear fascia/bumper in the

horizontal direction, depending on the location, type and

orientation of the obstacle.

ISPLAY

When the vehicle is in REVERSE, the instrument cluster

display will show the Park Assist ready system status.
The system will indicate a detected obstacle by showing a

single arc in one or more regions based on the obstacle’s

distance and location relative to the vehicle.
If an obstacle is detected in the center rear region, the

display will show a single solid arc in the center rear region

and will produce a one-half second tone. As the vehicle

moves closer to the obstacle, the display will show a single

arc moving closer to the vehicle and emit a fast sound

tone that will change from fast to continuous.
If an obstacle is detected in the left and/or right rear

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

and/or right rear region and will produce a fast sound

tone. As the vehicle moves closer to the obstacle, the

display will show the single arc moving closer to the

vehicle and the tone will change from fast to continuous.

162

STARTING AND OPERATING

The vehicle is close to the obstacle when the warning 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:

RECAUTIONS

NOTE:



Ensure that the rear fascia/bumper is free of snow, ice,

mud, dirt and debris to keep the ParkSense system

operating properly.



Jackhammers, large trucks, and other vibrations could

affect the performance of ParkSense.



When you turn ParkSense off, the instrument cluster

display will read “PARKSENSE OFF.” Furthermore, once

you turn ParkSense off, it remains off until you turn it

on again, even if you cycle the ignition.



ParkSense, when on, will reduce the volume of the

radio when it is sounding a tone.



Clean the ParkSense sensors regularly, taking care not

to scratch or damage them. The sensors must not be

covered with ice, snow, slush, mud, dirt or debris.

Failure to do so can result in the system not working

properly. The ParkSense system might not detect an

obstacle behind the fascia/bumper, or it could provide

a false indication that an obstacle is behind the fascia/

bumper.



Use the ParkSense switch to turn the ParkSense

system off if objects such as bicycle carriers, trailer

hitches, etc. are placed within 12 inches (30 cm) of the

rear fascia/bumper. Failure to do so can result in the

system misinterpreting a close object as a sensor

problem, causing the “PARKSENSE UNAVAILABLE

SERVICE REQUIRED” message to be displayed in the

instrument cluster display.

PARKVIEW REAR BACK UP CAMERA

The ParkView Rear Back Up Camera allows you to see an

on-screen image of the rear surroundings of your vehicle

whenever the gear selector is put into REVERSE. The

image will be displayed in the touchscreen display along

with a caution note to “Check Entire Surroundings” across

the top of the screen. After five seconds this note will

disappear. The ParkView camera is located on the rear of

the vehicle in the center of the spare tire.
Manual Activation Of The Rear View Camera
1. Press the Controls button located on the bottom of

the Uconnect display.

2. Press the Back Up Camera button to turn the Rear

View Camera system on.

WARNING!



Drivers must be careful when backing up even when

using ParkSense. Always check carefully behind your

vehicle, look behind you, and be sure to check for

pedestrians, animals, other vehicles, obstructions,

and blind spots before backing up. You are respon

sible for safety and must continue to pay attention to

your surroundings. Failure to do so can result in

serious injury or death.



Before using ParkSense, it is strongly recommended

that the ball mount and hitch ball assembly be

disconnected from the vehicle when the vehicle is

not used for towing. Failure to do so can result in

injury or damage to vehicles or obstacles because

the hitch ball will be much closer to the obstacle than

the rear fascia when the vehicle sounds the contin

uous tone. Also, the sensors could detect the ball

mount and hitch ball assembly, depending on its size

and shape, giving a false indication that an obstacle

is behind the vehicle.

CAUTION!



ParkSense is only a parking aid and it is unable to

recognize every obstacle, including small obstacles.

Parking curbs might be temporarily detected or not

detected at all. Obstacles located above or below the

sensors will not be detected when they are in close

proximity.



The vehicle must be driven slowly when using Park

Sense in order to be able to stop in time when an

obstacle is detected. It is recommended that the

driver looks over his/her shoulder when using Park

Sense.

will promote the growth of “microbes.” These microbes

form “slime” that will clog the fuel filtration system and

Your vehicle is equipped with a Selective Catalytic

Reduction (SCR) system to meet the very stringent diesel

emissions standards required by the Environmental

Protection Agency.
The purpose of the SCR system is to reduce levels of NOx

(oxides of nitrogen emitted from engines) that are harmful

to our health and the environment to a near-zero level. A

small quantity of Diesel Exhaust Fluid (DEF) is injected into

the exhaust upstream of a catalyst where, when

vaporized, it converts smog-forming nitrogen oxides (NOx)

into harmless nitrogen (N2) and water vapor (H2O), two

natural components of the air we breathe. You can

operate with the comfort that your vehicle is contributing

to a cleaner, healthier world environment for this and

generations to come.

CAUTION!

For diesel engines, only use diesel fuel for motor

vehicles in accordance with ASTM D-975 Grade S15

specifications. The use of other products or mixtures

may damage the engine beyond repair and

consequently void the warranty, due to the damage

caused. If you accidentally introduce other types of fuel

into the tank, do not start the engine. Empty the tank. If

the engine has been run for even an extremely limited

amount of time, you must not only drain the fuel tank,

but the rest of the supply circuit as well.

WARNING!

Do not open the high pressure fuel system with the

engine running. Engine operation causes high fuel

pressure. High pressure fuel spray can cause serious

injury or death.

STARTING AND OPERATING

System Overview

This vehicle is equipped with a Diesel Exhaust Fluid (DEF)

injection system and a Selective Catalytic Reduction (SCR)

catalyst to meet the emission requirements.
The DEF injection system consists of the following

components:



DEF tank



DEF pump



DEF injector



Electronically-heated DEF Lines



NOx sensors



Temperature sensors



SCR catalyst

The DEF injection system and SCR catalyst enable the

achievement of diesel emission requirements; while

maintaining outstanding fuel economy, drivability, torque

and power ratings.
For system messages and warnings see

page 108.

NOTE:



Your vehicle is equipped with a DEF injection system.

You may occasionally hear an audible clicking noise

from under the vehicle at a stop. This is normal opera

tion.



The DEF pump will run for a period of time after engine

shutdown to purge the DEF system. This is normal

operation and may be audible from the rear of the

vehicle.

Diesel Exhaust Fluid Storage

Diesel Exhaust Fluid (DEF) is considered a very stable

product with a long shelf life. If DEF is kept in

temperatures between 10° and 90°F (-12° and 32°C), it

will last a minimum of one year.
DEF is subject to freezing at the lowest temperatures. For

example, DEF may freeze at temperatures at or below

12°F (-11°C). The system has been designed to operate

in this environment.

NOTE:

When working with DEF, it is important to know that:



Any containers or parts that come into contact with DEF

must be DEF compatible (plastic or stainless steel).

Copper, brass, aluminum, iron or non-stainless steel

should be avoided as they are subject to corrosion by

DEF.



If DEF is spilled, it should be wiped up completely.

Adding Diesel Exhaust Fluid

The DEF gauge (located on the instrument cluster display)

will display the level of DEF remaining in the tank

page 108.

NOTE:

Driving conditions (altitude, vehicle speed, load, etc.) will

affect the amount of DEF that is used in your vehicle.

DEF FILL PROCEDURE

NOTE:

For the correct DEF fluid type see

page 374.

1. Remove cap from DEF fill inlet (located in fuel door).

Fuel and Diesel Exhaust Fluid Fill Location

2. Insert DEF fill adapter/nozzle into DEF fill inlet.

NOTE:



The DEF gauge may take up to five seconds to

update after adding a gallon or more of Diesel

Exhaust Fluid (DEF) to the DEF tank. If you have a

fault related to the DEF system, the gauge may not

update to the new level. See an authorized dealer

for service.



The DEF gauge may also not immediately update

after a refill if the temperature of the DEF fluid is

below 12°F (-11°C). The DEF tank heater will
