2014 JEEP CHEROKEE Owners Manual

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.

Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
stability reasons, with no target vehicle detected. Oncethe vehicle is out of the curve the system will resume
your original Set Speed. This is a part of normal ACC
system functionality.
NOTE:
On tight turns ACC performance may be limited.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and
it may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until
it is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be atten-
tive and ready to apply the brakes if necessary.
ACC Hill Example

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be
sufficient distance to the vehicle ahead.

Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and
the vehicle ahead is stopped in your lane. Always be
attentive and ready to apply the brakes if necessary.

Normal (Fixed Speed) Electronic Speed
Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be
operated if the vehicle speed is above 20 mph (32 km/h).
