NOTE:The minimum speed for FCW activation is
10 mph (16 km/h).
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 settings can only be changed when the vehicle is in
PARK.
FCW Message

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 191

The default status of FCW is the “Far” setting, this allows
the system to warn you of a possible collision with the
vehicle in front of you when you are farther away. This
gives you the most reaction time.Changing the FCW status to the “Near” setting, allows
the system to warn you of a possible collision with the
vehicle in front of you when you are much closer. This
setting provides less reaction time than the “Far” setting,
which allows for a more dynamic driving experience.

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 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 —
IF EQUIPPED
The ParkSense Rear 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 ParkSense System
Usage Precautions for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the shift lever is in
REVERSE. If ParkSense is 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).
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 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.
ParkSense Warning Display
The ParkSense Warning 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.
