2016 JEEP GRAND CHEROKEE display

•When you use the SET -button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
• The ACC system applies the brake down to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, the host vehicle
will release the vehicle brakes two seconds after com-
ing to a full stop.
• The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed. When driving up hill and down hill, the
ACC system will cancel if the braking temperature
exceeds normal range (overheated).Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the DID.
Distance Setting 4 Bars (Longest)
202 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To increase the distance setting, push the Distance Setting
— Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).To decrease the distance setting, push the Distance Set-
ting — Decrease button and release. Each time the button
is pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the DID displays the “Sensed Vehicle Indica-
tor” icon, and the system adjusts vehicle speed automati-
cally to maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance until:
•
The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of
the sensor.
Distance Setting 1 Bar (Short)

Overtake Aid
When driving with ACC engaged and following a ve-
hicle, the system will provide an additional acceleration
up to the ACC set speed to assist in passing the vehicle.
This additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active when
passing on the left hand side.
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 release.A cancel message will display on the DID and produce a
warning chime. 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 release. A cancel message will display
on the DID and produce a warning chime. Driver inter-
vention will be required at this moment.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow
these warnings can result in a collision and death or
serious personal injury.

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 DID 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 thevehicle 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.
208 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•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 Wind-
shield” warning will display and also a chime will indicate
when conditions temporarily limit system performance.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 209

This most often occurs at times of poor visibility, 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 DID will display “ACC/FCW
Limited Functionality Clean Front Windshield” and the
system will have degraded performance.
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 DID 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 func-
tionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable.
If this occurs, try activating ACC again later, following an
ignition cycle. If the problem persists, see your autho-
rized dealer.
