2021 CHRYSLER PACIFICA HYBRID Owners Manual

STARTING AND OPERATING151
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
20 mph (32 km/h).
When the system is turned on and in the READY
state, the instrument cluster displays “ACC Ready.”
When the system is off, the instrument cluster
display “Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following condi -
tions:
When the brakes are applied
When the parking brake is applied
When the automatic transmission is in PARK,
REVERSE or NEUTRAL
When the vehicle speed is below the minimum
speed range
When the brakes are overheated
When the driver’s door is open at low speeds
When the driver’s seat belt is unbuckled at low
speeds
To Activate/Deactivate
Push and release the Adaptive Cruise Control
(ACC) on/off button. The ACC menu in the
instrument cluster will read “ACC Ready.” To turn the system off, push and release the
Adaptive Cruise Control (ACC) on/off button again.
At this time, the system will turn off and the
instrument cluster display will show “Adaptive
Cruise Control (ACC) Off.”
To Set A Desired Speed
When the vehicle reaches the speed desired, push
the SET
(+) button or the SET (-) button and
release. The instrument cluster display will show
the set speed.
NOTE:Fixed Speed Cruise Control can be used ACC
enabled. To change between the different modes,
push the ACC on/off button which turns the ACC
and the Fixed Speed Cruise Control off. Pushing
the Fixed Speed Cruise Control on/off button will
result in turning on (changing to) Fixed Speed
Cruise Control mode. If ACC is set when the vehicle speed is
below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h).
If either system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the
message “DRIVER OVERRIDE” will display in the
instrument cluster display.
WARNING!
Leaving the Adaptive Cruise Control (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 a collision. Always leave the system off
when you are not using it.
WARNING!
In the Fixed Speed Cruise Control mode, the
system will not react to vehicles ahead. In
addition, the proximity warning does not activate
and no alarm will sound even if you are too close
to the vehicle ahead since neither the presence
of the vehicle ahead nor the vehicle-to-vehicle
distance is detected. Be sure to maintain a safe
distance between your vehicle and the vehicle
ahead. Always be aware which mode is selected.

152STARTING AND OPERATING
If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
be controlling the distance between your vehicle
and the vehicle ahead. The vehicle speed will
only be determined by the position of the accel-
erator pedal.
To Cancel
The following conditions cancel the ACC or Fixed
Speed Cruise Control systems:
The brake pedal is applied
The CANC (cancel) button is pushed
The Anti-Lock Brake System (ABS) activates
The gear selector is removed from the DRIVE
position
The Electronic Stability Control/Traction Control
System (ESC/TCS) activates
The vehicle parking brake is applied
The braking temperature exceeds normal range
(overheated).
The following conditions will only cancel the ACC
system:
Driver seat belt is unbuckled at low speeds
Driver door is opened at low speeds
To Turn Off
The system will turn off and clear the set speed in
memory if:
The Adaptive Cruise Control (ACC) on/off button
is pushed
The Fixed Speed Cruise Control on/off button is
pushed
The ignition is placed in the OFF position
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 instrument cluster
display will display the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
NOTE:
If your vehicle is at a standstill longer than two
seconds, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the Adaptive Cruise Control
(ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
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.

21_RUP_OM_EN_USC_t.book Page 152

STARTING AND OPERATING153
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
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 An ACC Is Active:
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 the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds the driver will either have to
push 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 uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, 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 instrument cluster display.
Distance Settings

To increase the distance setting, push the
Distance 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 Decrease button and release. Each time
the button is pushed, the distance setting
decreases by one bar (shorter). 1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
4

21_RUP_OM_EN_USC_t.book Page 153

154STARTING AND OPERATING
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 instrument
cluster displays the ACC Set With Target Detected
Indicator Light, 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.
The distance setting is changed.
The system disengages Ú page 151.
The maximum braking applied by ACC is limited;
however, 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
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC)
engaged and following a vehicle, 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
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle in
front, your vehicle will resume motion, without the
need for any driver action, if the vehicle in front
starts moving within two seconds.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the driver will either have to push 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 stand -
still for approximately three consecutive minutes,
the parking brake will be activated, and the ACC
system will be cancelled.
While the ACC system is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or the
driver door is opened, the parking brake will be
activated, and the ACC system will be cancelled.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR” WARNING
The “ACC/AEB Unavailable Wipe Front Radar
Sensor” warning will display and a chime will
sound when conditions temporarily limit system
performance.
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.

21_RUP_OM_EN_USC_t.book Page 154

STARTING AND OPERATING155
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 instrument cluster display will show
“ACC/AEB Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/AEB Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e. ice and
snow, or tunnels with reflective tiles). The ACC
system will recover after the 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/AEB Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
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
important 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 malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market 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/AEB 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 an authorized dealer.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/AEB Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. 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, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/AEB
Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
The “ACC/AEB 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 rearview
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 functionality.
NOTE:If the “ACC/AEB 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 an authorized
dealer.

156STARTING AND OPERATING
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. 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 an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when using
ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no vehicle in
front detected. Once the vehicle is out of the curve
the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.
Turn Or Bend Example

21_RUP_OM_EN_USC_t.book Page 156

STARTING AND OPERATING157
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 performance may be limited.
NOTE:The driver must maintain control of the vehicle,
remain alert, and be ready to apply the brakes if
needed.

ACC Hill Example

LANE CHANGING
ACC may not detect a vehicle until it is completely
in the lane in which you are traveling. In the lane
changing example below, 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.
Lane Changing Example

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.
Narrow Vehicle Example

21_RUP_OM_EN_USC_t.book Page 157

158STARTING AND OPERATING
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.

Stationary Object And Stationary Vehicle Example
PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
The vehicle brakes may be automatically applied
and released when performing a reverse parking
maneuver if the system detects a possible collision
with an obstacle.
NOTE:
The driver can override the automatic braking
function by pressing the gas pedal over 90% of
its capacity during the braking event, turning
ParkSense off via the ParkSense switch, or
changing the gear while the automatic brakes
are being applied.
Automatic brakes will not be available if ESC is
not available.
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 not provide
enough vehicle deceleration to avoid colliding
with a detected obstacle depending on vehicle
speed, road conditions, and brake capability.
The automatic braking function may not be
applied fast enough for moving obstacles that
approach the rear of the vehicle from the left
and/or right sides.
The automatic braking function can be
enabled/disabled from the Customer-Program -
mable Features section of the Uconnect system.
ParkSense will retain its last known configura -
tion 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 obstacles when backing up in REVERSE
gear.
