NOTE:Do not change the adjustment fasteners or pull
the sensor off of the bracket. Doing so may misalign the
sensor.
Store the sensor and bracket assembly in a safe location.
The wiring and connector must be stowed properly after
the sensor and bracket assembly is removed.
A connector plug is stowed on top of the bumper beam.
Insert the wiring connector into the connector plug.
NOTE:When the sensor is removed, Adaptive Cruise
Control, Normal Cruise Control, and Forward Collision
Warning will not be available. The cluster will display the
warning “ACC/FCW Unavailable - Service Radar Sen-
sor.”To reinstall the sensor and bracket assembly reverse the
process above. The fastener torque required to assembly
the bracket back to the beam is 6.6 ft lbs (9 Nm).
ACC Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be 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 a key
cycle. If the problem persists, see your authorized dealer.3

Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, 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.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.

WARNING!
In the normal 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
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.
To Set A Desired Speed
When the vehicle reaches the speed desired, press the
SET-button and release. The EVIC will display the set
speed.
NOTE:You must observe the display when setting or
changing speed, not the speedometer.
To Vary The Speed Setting
There are two ways to change the set speed:
•Use the accelerator pedal to adjust the vehicle to the
desired speed and press the SET-button.
•Tap the RES+or SET-button to increase or decrease
the set speed in 1 mph (1.6 km/h) increments respec-
tively. Hold the RES+or SET-button for 5 mph
(8 km/h) increments.
To Cancel
The system will disable normal Cruise Control without
erasing the memory if:
•You softly tap or depress the brake pedal.
•You press the CANCEL button.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.

To Resume
Press the RES+button and then remove your foot from
the accelerator pedal. The EVIC will display the last set
speed.
To Turn Off
The system will turn off and erase the set speed in
memory if:
•You push the ON/OFF button.
•You turn off the ignition.
•You engage Four-Wheel Drive Low.
If the Cruise Control system is turned off and reactivated,
the system will return to the last driver setting (ACC or
Normal Cruise Control).
Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.
224 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:
•The minimum speed for FCW activation is 10 mph
(16 km/h).
•When entering or driving in a curve, the FCW alerts
may be triggered on objects other than vehicles such asguard rails or sign posts based on the course predic-
tion. This is expected and is a part of normal FCW
activation and functionality.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect
every type of collision. The driver has the responsi-
bility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
Changing FCW Status
The FCW feature can be set to far, set to near or turned off
in the Electronic Vehicle Information Center (EVIC) refer
to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation. The FCW Status Off, Near or Far will be
displayed in the EVIC.
FCW Message

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 225

Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
NOTE:In the “Off” setting FCW OFF will be displayed
in the EVIC.NOTE:
•The system will retain the last setting selected by the
driver after ignition shut down.
•FCW will not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path

of the car, stationary objects that are far away, oncom-
ing traffic, or leading vehicles with the same or higher
rate of speed.
•FCW will be disabled like ACC below with the un-
available screens.
FCW Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be a
temporary malfunction that limits FCW functionality.
Although the vehicle is still drivable under normal
conditions, FCW will be temporarily unavailable. If this
occurs, try activating FCW again later, following a key
cycle. If the problem persists, see your authorized dealer.
Service FCW Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicatesthere is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.ACC/FCW Unavailable Warning

PARKSENSEREAR PARK ASSIST — IF
EQUIPPED
The ParkSenseRear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSenseSystem
Usage Precautions for limitations of this system and
recommendations.
ParkSensewill retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSensecan be active only when the shift lever is in
REVERSE. If ParkSenseis enabled at this shift lever
position, the system will remain active until the vehicle
speed is increased to approximately 11 mph (18 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
10 mph (16 km/h).
ParkSenseSensors
The four ParkSensesensors, 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 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSenseWarning Display
The ParkSenseWarning screen will only be displayed if
Sound and Display is selected from the Customer- Pro-
grammable Features section of the Electronic Vehicle
Information Center (EVIC). Refer to “Electronic Vehicle
Information Center (EVIC)/Personal Settings (Customer-
Programmable Features)” in “Understanding Your In-
strument Panel” for further information.
