2018 JEEP GRAND CHEROKEE cruise control

• If the button is continually pushed, the set
speed will continue to decrease in 10 km/h
decrements until the button is released.
The decrease in set speed is reflected in
the instrument cluster display.
To Resume
If there is a set speed in memory push the
RES (resume) button and then remove your
foot from the accelerator pedal. The instru-
ment cluster display will show the last set
speed.
NOTE:
• If your vehicle stays at standstill for longer
than two seconds, then the system will
cancel and the brake force will be ramped-
out. The driver will have to apply the brakes
to keep the vehicle at a standstill.
• ACC cannot be resumed if there is a sta-
tionary vehicle in-front of your vehicle in
close proximity.
WARNING!
The Resume function should only be used
if traffic and road conditions permit. Re-
suming a set speed that is too high or too
low for prevailing traffic and road condi-
tions could cause the vehicle to accelerate
or decelerate too sharply for safe opera-
tion. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
Deactivation
Push and release the Adaptive Cruise Control
(ACC) on/off button a second time to turn the
system off.
“Adaptive Cruise Control (ACC) Off” will ap-
pear in the instrument cluster display to
indicate the ACC is off.
WARNING!
Leaving the ACC system on when not in
use is dangerous. You could accidentally
set the system or cause it to go faster than
you want. You could lose control and have
WARNING!
an accident. Always leave the system OFF
when you are not using it.
Setting The Following Distance
The specified following distance for ACC can
be set by varying the distance setting be-
tween 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 appears
in the instrument cluster display.
• To increase the distance setting, push the
Distance Setting—Increase button and re-
lease. Each time the button is pushed, the
distance setting increases by one bar (lon-
ger).
• To decrease the distance setting, push the
Distance Setting—Decrease button and re-
lease. Each time the button is pushed, the
distance setting decreases by one bar
(shorter).
STARTING AND OPERATING
168

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 stand-
still, 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 instrument clus-
ter display 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 un-
buckled 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 instrument cluster display and produce a
warning chime. Driver intervention will be
required at this moment.
WARNING!
When the ACC system is resumed, the
driver must ensure that there are no pedes-
trians, vehicles or objects in the path of
the vehicle. Failure to follow these warn-
ings can result in a collision and death or
serious personal injury.
Changing Modes
If desired, the Adaptive Cruise Control mode
can be turned off and the system can be
operated as a Normal (Fixed Speed) Cruise
Control mode. When in the Normal (Fixed
Speed) Cruise Control mode the distance
setting feature will be disabled and the sys-
tem will maintain the speed you set.
• To change between the different cruise con-
trol modes, push the Adaptive Cruise Con-
trol (ACC) on/off button which turns the
ACC and the Normal (Fixed Speed) Cruise
Control off.
• Pushing the Normal (Fixed Speed) Cruise
Control on/off button will result in turning
on (changing to) the Normal (Fixed Speed)
Cruise Control mode.Refer to your Owner's Manual for further
information.
WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete atten-
tion is always required while driving to
maintain safe control of your vehicle. Fail-
ure to follow these warnings can result in a
collision and death or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
• Cannot take street, traffic, and weather
conditions into account, and may be
169

WARNING!
limited upon adverse sight distance con-
ditions.
• Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for 2 seconds in the stop
position. If the target vehicle does not
start moving within two seconds the ACC
system will display a message that the
system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the
brakes are released.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway con-
struction zones).
• When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
WARNING!
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for main-
taining an appropriate distance between
vehicles.
• Normal (Fixed Speed) Cruise Control
mode for cruising at a constant preset
speed. For additional information, refer
to “Normal (Fixed Speed) Cruise Control
Mode” in your Owner’s Manual.
Normal (Fixed Speed) Cruise Control will
not react to preceding vehicles. Always be
aware of the mode selected.
You can change the mode by using the
Cruise Control buttons. The two control
modes function differently. Always con-
firm which mode is selected.
PARKSENSE REAR PARK
ASSIST
ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
Activation/Deactivation ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch
.
When the ParkSense switch is pushed to
disable the system, the instrument cluster
display will show the “PARKSENSE OFF”
message for approximately five seconds. Re-
fer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” in the
Owner’s Manual for more information. When
the gear selector is moved to REVERSE and
