“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 per-
formance. This most often occurs at times of poor visibil-
ity, 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 EVIC will
display “ACC/FCW Limited Functionality Clean Front
Windshield” and the system will have degraded perfor-
mance.
The “ACC/FCW Limited Functionality Clean Front
Windshield” message can sometimes be displayed while
driving 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 should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may
require cleaning or removal of an obstruction.
When the condition that created limited functionality is
no longer present, the system will return to full function-
ality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” 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 your authorized dealer.

Service ACC/FCW Warning
If the system turns off, and the EVIC displays “ACC/FCW
Unavailable Service Required”or “Cruise/FCW Unavail-
able Service Required”, there may be an internal system
fault or a temporary malfunction that limits ACC function-
ality. 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.
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.
Towing A Trailer
NOTE:Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

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, press the forward collision
button once to turn the system OFF (led turns on).
To turn the FCW system back ON, press the forward
collision button again to turn the system ON (led turns
off).
Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
Changing the Active Braking status to “Off” prevents the
system from providing limited autonomous braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision.
NOTE:
The FCW system state is kept in memory from
one key cycle to the next. If the system is turned OFF,
it will remain off when the vehicle is restarted.

The default status of FCW is the “Far” setting and the
Active Braking is the “On” setting, this allows the system
to warn you of a possible collision with the vehicle in
front of you when you are farther away and it applies
limited braking. This gives you the most reaction time to
avoid a possible collision.
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.
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 system turns off, and the EVIC displays “ACC/
FCW Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield” momentarily,
there may be a condition that limits FCW functionality.
Although the vehicle is still drivable under normal
conditions, the active braking may not be fully available.
Once the condition that limited the system performance
is no longer present, the system will return to its full
performance state. If the problem persists, see your
authorized dealer.

Service FCW Warning
If the system turns off, and the EVIC 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 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 7 mph (11 km/h) or
above. When in REVERSE and above the system’s oper-
ating speed, a warning will appear in the EVIC 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
