JEEP GRAND CHEROKEE LIMITED 2019 Owners Manual

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.
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 ACC
system 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 attentive
and ready to apply the brakes if necessary.

STARTING AND OPERATING 309

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.

by the party responsible for compliance could void the
user ’s authority to operate the equipment.
Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
at fixed speeds. The Normal (Fixed Speed) Cruise Control
mode is designed to maintain a set cruising speed without
requiring the driver to operate the accelerator. Cruise
Control can only be operated if the vehicle speed is above
20 mph (32 km/h).
To change between the different control modes, push the
Adaptive Cruise Control (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.

• Pushing 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 pushed, 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 instrument cluster display.
To Decrease Speed
When the Normal (Fixed Speed) Cruise Control is set, you
can decrease speed by pushing the SET (-)button.
The driver’s preferred units can be selected through the
instrument cluster display. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed decre-
ment shown is dependant on the speed of U.S. (mph) or
Metric (km/h) units:
U.S. Speed (mph)
• Pushing 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 pushed, the set speed will
continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is reflected
in the instrument cluster display.

Metric Speed (km/h)
•Pushing 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 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 Cancel
The following conditions will cancel the Normal (Fixed
Speed) Cruise Control without clearing the memory:
•The brake pedal is applied.
• The CANC button is pushed.
• The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
• The vehicle parking brake is applied.
• The braking temperature exceeds normal range (over-
heated).
• The gear selector is removed from the DRIVE position.
• The driver switches ESC to full-off mode.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. If your vehicle is equipped with an
automatic transmission, the vehicle brakes may be auto-
matically applied and released when performing a reverse
parking maneuver if the system detects a possible collision
with an obstacle.
6
STARTING AND OPERATING 313

NOTE:
•The driver can override the automatic braking function
by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic brakes are being applied.
• Automatic brakes are not available if the vehicle is in
4LO.
• Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
• The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
• The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
• The automatic braking function can be enabled/
disabled from the Customer-Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles. The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected ob-
stacles when backing up in REVERSE gear.
NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided to assist the driver and not to
substitute the driver.
• The driver must stay in full control of the vehicle’s
acceleration and braking and is responsible for the
vehicle’s movements.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommenda-
tions.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
314 STARTING AND OPERATING

above. When in REVERSE and above the system’s operat-
ing speed, a warning will appear within the instrument
cluster display indicating the vehicle speed is too fast. The
system will become active again if the vehicle speed is
decreased to speeds less than approximately 6 mph
(9 km/h).
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 direc-
tion, depending on the location, type and orientation of the
obstacle.
ParkSense Display
The ParkSense display is always shown in the instrument
cluster display as long as the vehicle is in REVERSE.The system will indicate a detected obstacle by showing a
single arc in the left and/or right rear regions based on the
obstacle’s distance and location relative to the vehicle.

If an obstacle is detected in the left and/or right rear
region, the display will show a single arc in the left and/or
right rear region and the system will produce a tone. As the
vehicle moves closer to the obstacle, the display will show
the single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.
