2014 JEEP CHEROKEE Owners Manual

•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 decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two
seconds the driver will either have to press the RES
(resume) button, or apply the accelerator pedal to
reengage the ACC to the existing Set Speed.
• 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 EVIC.
Distance Setting 4 Bars (Longest)

To increase the distance setting, press the Distance Setting
— Increase button and release. Each time the button is
pressed, the distance setting increases by one bar (longer).
To decrease the distance setting, press the Distance Setting
— Decrease button and release. Each time the button is
pressed, 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 EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically 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.
• The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
Distance Setting 1 Bar (Short)

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.
Brake Alert

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 driver
will either have to press the RES (resume) button, or
apply the accelerator pedal to reengage the ACC to the
existing Set Speed.
NOTE:After the ACC system holds your vehicle at a
standstill for approximately 3 consecutive minutes, the
parking brake will be activated, and the ACC system will
be cancelled.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 203

While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened,
the parking brake will be activated, and the ACC system
will be cancelled.
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.
Adaptive Cruise Control (ACC) Menu
The EVIC displays the current ACC system settings. The
EVIC is located in the center of the instrument cluster.
The information it displays depends on ACC system
status.Press the ADAPTIVE CRUISE CONTROL (ACC) ON/
OFF button (located on the steering wheel) until one of
the following displays in the EVIC:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adap-
tive Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated but the vehicle speed setting has
not been selected, the display will read “Adaptive Cruise
Control Ready.”
Press the SET + or the SET- button (located on the steering
wheel) and the following will display in the EVIC:
ACC SET
When ACC is set, the set speed will display in the
instrument cluster.

The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
•Distance Setting Change
• System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable Warning
• The EVIC will return to the last display selected after
five seconds of no ACC display activityDisplay 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
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 205

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.
