2014 JEEP CHEROKEE warning

vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
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 in the center of the
vehicle behind the lower 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. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, 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 “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.

NOTE:
•If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstruction, have the radar sensor realigned at
your authorized dealer.
• Installing a snow plow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“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 functionality.
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
Unavailable Service Required”, there may be an internal
system fault or 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.
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.
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.

FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC), and may apply a
brake jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
216 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning. If
the driver does not take action based upon these progres-
sive warnings, then the system will provide a limited
level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by
braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required. When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.
FCW Message

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 217

NOTE:
•The minimum speed for FCW activation is 5 mph
(10 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 a key cycle, the Active Braking portion of FCW
will be deactivated until the next key 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.
218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 FCW sensitivity - Near vs. Far. Far warns
the driver of a possible collision earlier and Near
warns the driver later.
• Changing the Active Braking status to “Off” prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
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.
