To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
s p

eed 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
s u
bsequent 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
sp
eed 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
s u
bsequent 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
u n
til 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.
4

98 STARTING AND OPERATING
When ACC Is Active:
NOTE:
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.
The ACC will bring the vehicle to a complete stop
while following a vehicle in front and hold the
vehicle for two seconds in the stop position. If
the vehicle in front 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.
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
D i

stance 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
D
i

stance 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
ma
intain 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
u n

til:
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 Ú page 96.
The maximum braking applied by ACC is limited;
h ow

ever, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the ACC
s y
stem applies the brakes.
A Proximity Warning will alert the driver if ACC
pr
edicts that its maximum braking level is not
sufficient to maintain the set distance. If this
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 99
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
d i
splay 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 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 (Lane Change Assist feature included) and
will only be active when passing on the left hand
side. Switching lanes will not impact the ACC
system if the driver is already traveling at the set
speed.
ACC Operation At Stop
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle in
front, your vehicle will resume motion without any
driver interaction if the vehicle in front starts
moving within two seconds of your vehicle coming
to a standstill. If the vehicle in front does not start moving within
t
w

o 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
s t

andstill, 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. 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
indicate when conditions temporarily limit system
performance. This most often occurs at times of poor visibility,
s
u

ch 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 will display the above
message and the system will deactivate.
This message can sometimes be displayed while
d r

iving 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
S e
nsor” warning is active, Fixed Speed Cruise
Control is still available.
If weather conditions are not a factor, the driver
s h

ould 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
im
portant to note the following maintenance items:

Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be careful 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.
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.
4

100 STARTING AND OPERATING
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
s y

stem 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.
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 also a chime
will indicate 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
d
r

iving 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
s h

ould 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
f u

nctionality is no longer present, the system will
return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front
W i
ndshield” 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.

STARTING AND OPERATING 103
PARKSENSE FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear and/or front fascia/bumper and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver).
For limitations of this system and
re

commendations, see Ú page 107.
ParkSense will retain the system state (enabled or
d i

sabled) from the previous ignition cycle when the
ignition is changed to the ON/RUN position.
ParkSense can be active only when the gear
s e

lector 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
(1

1 km/h) or above. The system will become active
a g
ain if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h).
PARKSENSE SENSORS
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 th
e rear fascia/bumper. These distances depend
on the location, type, and orientation of the
obstacle in the horizontal direction.
The six ParkSense sensors, located in the front
f a

scia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
th

e front fascia/bumper. These distances depend
on the location, type, and orientation of the
obstacle in the horizontal direction.
PARKSENSE DISPLAY
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
sh
owing 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,
th
e 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 the single arc moving closer to
the vehicle and the tone will change from slow, to
fast, to continuous. If an obstacle is detected in the left and/or right
r
e

ar 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.
If an obstacle is detected in the center front region,
t h

e display will show a single arc in the center front
region. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to
the vehicle. A fast sound tone will be produced
when reaching the second flashing arc and will
change to a continuous tone when the first flashing
arc appears.
If an obstacle is detected in the left and/or right
f r

ont region, the display will show a single flashing
arc in the left and/or right front region and will
produce a fast 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.

SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or the "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for
five seconds. When the gear selector is moved to
REVERSE and the system has detected a faulted
condition, the instrument cluster display will
display a "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE FRONT SENSORS" or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" pop-up message for five
seconds. After five seconds, a vehicle graphic will
be displayed with "UNAVAILABLE" at either the
front or rear sensor location depending on where
the fault is detected. The system will continue to
provide arc alerts for the side that is functioning
properly. These arc alerts will interrupt the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" messages if an object is
detected within the five second pop-up duration.
The vehicle graphic will remain displayed for as
long as the vehicle is in REVERSE.
If "PARKSENSE UNAVAILABLE WIPE REAR
S
E

NSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.
If the "PARKSENSE UNAVAILABLE SERVICE
R E

QUIRED" message appears in the instrument

STARTING AND OPERATING 107
(Continued)
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear bumpers are free
of snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF.” Once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense is turned off,
the instrument cluster will display “PARKSENSE
OFF” for as long as the vehicle is in REVERSE.
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 or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of 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
(3

0 cm) from 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.
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 responsible 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 recom -
mended that the ball mount and hitch ball
a s
sembly 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/bumper when the vehicle sounds
the continuous 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
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
s h

oulder when using ParkSense.
WARNING!
