JEEP GRAND CHEROKEE 2014 WK2 / 4.G SRT Owners Manual

•The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity. When this occurs, you should immediately apply the
brakes as needed to maintain a safe distance from the
vehicle ahead.

Overtake Aid
When driving with ACC engaged and following a target
vehicle, the system will provide an additional accelera-
tion to assist in passing vehicles in front. This additional
acceleration is triggered when the driver utilizes the left
turn signal. In locations with left hand drive traffic,
Overtake Aid is active only when passing on the left
hand side of the Target vehicles.
When a vehicle goes from a location with left hand drive
traffic to a location with right hand drive traffic, the ACC
system will automatically detect traffic direction. In this
condition, Overtake Aid is active only when passing on
the right side of the Target vehicle. This additional
acceleration is triggered when the driver utilizes the right
turn signal. In this condition the ACC system will no
longer provide Overtake Aid on the left side until it
determines that the vehicle has moved back to a location
with left hand drive traffic.
ACC Operation at Stop
If the ACC system brings your vehicle to a standstill
while following a target vehicle, if the target vehicle starts
moving within two seconds of your vehicle coming to a
standstill, your vehicle will resume motion without the
need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the ACC
with Stop system will cancel and the brakes will ramp-
out. Driver intervention will be required at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seatbelt is unbuckled or the driver
door is opened, the ACC with Stop system will cancel
and the brakes will ramp-out. Driver intervention will be
required at this moment.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud,
dirt or ice. In these cases, the EVIC will display “ACC/
FCW Unavailable Wipe Front Radar Sensor” and the
system will deactivate. The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after the
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.
212 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 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.
Offset Driving Condition Example

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. Once
the 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.
Turn Or Bend Example

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 ACCsystem 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.

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.
