2015 JEEP CHEROKEE Owners Manual

WARNING!
The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to accelerate
or decelerate too sharply for safe operation. Failure to
follow these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by
pressing the SET+button.
The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•Pressing the SET+button once will result ina1mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
•If the button is continually pressed, the set speed will
continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the EVIC/DID.
Metric Speed (km/h)
•Pressing the SET+button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the
button results in an increase of 1 km/h.
•If the button is continually pressed, the set speed will
continue to increase in 10 km/h increments until the
button is released. The increase in set speed is reflected
in the EVIC/DID.

To Decrease Speed
While ACC is set, the set speed can be decreased by
pressing the SET-button.
The speed decrement shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•Pressing the SET-button once will result ina1mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph.
•If the button is continually pressed, the set speed will
continue to decrease in 5 mph increments until the
button is released. The decrease in set speed is re-
flected in the EVIC/DID.
Metric Speed (km/h)
•Pressing the SET-button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h.
•If the button is continually pressed, the set speed will
continue to decrease in 10 km/h increments until the
button is released. The decrease in set speed is re-
flected in the EVIC/DID.
NOTE:
•When you override and push the SET+button or SET
-buttons, the new Set Speed will be the current speed
of the vehicle.
•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/DID.
Distance Setting 4 Bars (Longest)

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 201

Distance Setting 3 Bars (Long)Distance Setting 2 Bars (Medium)
202 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To increase the distance setting, press the Distance Set-
ting — 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/DID displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle speed
automatically 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)

•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/DID and a chime will
sound while ACC continues to apply its maximum
braking capacity.
NOTE:The “Brake!” Screen in the EVIC/DID is a warn-
ing for the driver to take action and does not necessarily
mean that the Forward Collision Warning system is
applying the brakes autonomously.
Brake Alert
204 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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
In the event that 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.
While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened,

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 205

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/DID displays the current ACC system set-
tings. The EVIC/DID 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/DID:
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/DID:
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:
