NOTE:
•The minimum speed for FCW activation is 5 mph
(8 km/h).
•The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
•It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
•The FCW system is intended for on-road use only. If
the vehicle is taken off-road, the FCW system should
be deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range,
the FCW system will be automatically deactivated.WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect
every type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.
Turning FCW ON Or OFF
NOTE:The default status of FCW is “On”, this allows
the system to warn you of a possible collision with the
vehicle in front of you.
The forward collision button is located on the switch
panel below the Uconnect® display.
To turn the FCW system OFF, push the forward collision
button once to turn the system OFF (led turns on).

NOTE:
•The system will retain the last setting selected by the
driver after ignition shut down.
•FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects not in the
path of the car, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
•FCW will be disabled like ACC, with the unavailable
screens.
FCW Limited Warning
If the DID displays “ACC/FCW Limited Functionality”
or “ACC/FCW Limited Functionality Clean Front Wind-
shield” momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still drivable
under normal conditions, the active braking may not befully available. Once the condition that limited the sys-
tem performance is no longer present, the system will
return to its full performance state. If the problem per-
sists, see your authorized dealer.
Service FCW Warning
If the system turns off, and the DID displays:
•ACC/FCW Unavailable Service Required
•Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
PARKSENSE® REAR 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/gear
selector is in REVERSE. If ParkSense® is enabled at this
shift lever/gear selector position, the system will remain
active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. When in REVERSE
and above the system’s operating speed, a warning willappear within the Driver Information Display (DID)
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).
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.
