The Headlights On with Wipers feature can be turned on
or off through the Electronic Vehicle Information Center
(EVIC) (if equipped). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. This
feature is especially useful for road splash or over spray
from the windshield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of the six
intermittent wiper settings to activate this feature.
The sensitivity of the system is adjustable from the
multifunction lever. Wiper delay position 1 is the least
sensitive and wiper delay position 6 is the most sensitive.
Choose setting 3 or 4 for normal rain conditions. Choose
setting 2 or 1 if you desire less wiper sensitivity. Choose
setting 5 or 6 if you desire more sensitivity. The rain sensewipers will automatically change between an intermit-
tent wipe, slow wipe and a fast wipe depending on the
amount of moisture that is sensed on the windshield.
Place the multifunction lever in the off position when not
using the system.
NOTE:
•The Rain Sensing feature will not operate when the
wiper speed is in the low or high position.
•The Rain Sensing feature may not function properly
when ice or dried salt water is present on the wind-
shield.
•Use of Rain-X
or products containing wax or silicone
may reduce rain sensor performance.
•The Rain Sensing feature can be turned on and off
through the EVIC (if equipped). Refer to “Electronic
Vehicle Information Center (EVIC)/Personal Settings
(Customer-Programmable Features)” in “Understand-
ing Your Instrument Panel” for further information.

ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
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 an infrared
sensor designed to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration automatically to
maintain a preset following distance, while matching
the speed of the vehicle ahead.
WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity 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 re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in an accident or serious personal injury.The
ACC system:
•Does not react to pedestrians, oncoming vehicles,
and stationary objects (i.e., a stopped vehicle in a
traffic jam or a disabled vehicle).(Continued)

Setting the Following Distance in ACC
The specified following distance for ACC can be set by
varying the distance setting between long, medium, and
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 EVIC.To change the distance setting, push the lever away from
you (DISTANCE) and release. Each time this is done, the
distance setting adjusts between long, medium, and
short.
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 EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically 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.
1 — Sensor Bars. Default Distance Setting is Three Bars = Long.

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 behind the grille,
slightly offset from the center of the grille.
To keep the ACC System operating properly, it is impor-
tant 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 or the
sensor mount. Doing so could cause an ACC system
malfunction or failure and require a sensor realign-
ment.
•If the sensor is damaged due to an accident, see your
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 “CRUISE
OFF” state and will resume function by simply reactivat-
ing it.

NOTE:Installing a vehicle front-end protector or an
aftermarket grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit ACC
operation.
ACC Unavailable Warning
If the system turns off, and the EVIC displays ACC
UNAVAILABLE, there may be a temporary malfunction
that limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be tempo-
rarily unavailable. If this occurs, try activating ACC again
later, following a key cycle. If the problem persists, see
your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “SERVICE
ACC,” it indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an authorized
dealer.

PARKSENSEREAR PARK ASSIST
The ParkSense Rear Park Assist system is a driver aid
that senses for obstacles behind the vehicle. Refer to
ParkSense System Usage Precautions for limitations of
this system and recommendations.
ParkSense is active when the driver shifts the transmis-
sion into the REVERSE position, and the parking brake is
not applied, and the vehicle speed is less than 10 mph
(16 km/h).
ParkSense can be turned on or off through the Electronic
Vehicle Information Center (EVIC) when the vehicle is in
PARK. Refer to “Electronic Vehicle Information Center
(EVIC)/Personal Settings (Customer-Programmable Fea-
tures)” in “Understanding Your Instrument Panel” for
further information. ParkSense
uses four sensors located in the rear bumper
to scan for obstacles up to 79 in (200 cm) away from the
rear bumper fascia. The ParkSense Warning Display
located above the rear window provides both visible and
audible warnings to indicate the range of the object.

ParkSenseSystem Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense Rear Park
Assist system operating properly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the ParkSense Rear Park
Assist system.
•When you turn ParkSense off, the instrument cluster
will display “PARK ASSIST DISABLED.” Further-
more, once you turn ParkSense off, it remains off
until you turn it on again, even if you cycle the ignition
key.
•When you move the shift lever to the REVERSE
position and ParkSense is turned off, the instrument
cluster will display “PARK ASSIST DISABLED” mes-
sage for as long as the vehicle is in REVERSE.
•ParkSense, when on, will MUTE the radio when it is
sounding a tone.
•If a ParkSense system malfunction occurs, a single
chime will sound once per ignition cycle. In addition,
the Electronic Vehicle Information Center (EVIC) will
display “SERVICE PARK ASSIST SYSTEM” and the
LED in the ParkSense switch will illuminate. If this
occurs after making sure the rear fascia/bumper is
clean and clear of snow, ice, mud, dirt, or other
obstruction, see your authorized dealer for service.
•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 ParkSense 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.
186 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•Objects must not be within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the instrument cluster.
CAUTION!
•The ParkSenseRear Park Assist system 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 prox-
imity.
(Continued)
CAUTION! (Continued)
•The vehicle must be driven slowly when using the
ParkSenseRear Park Assist system to be able to
stop in time when the obstacle is detected. It is
recommended that the driver looks over his/her
shoulder when using ParkSense.
