2018 CHRYSLER PACIFICA HYBRID Owners Manual

To Decrease Speed
While ACC is set, the set speed can be decreased by
pushing the SET(-)button.
The driver’s preferred units can be selected through the
Uconnect Settings if equipped. Refer to “Uconnect Set-
tings” in “Multimedia” for more information. The speed
decrement shown is dependant on the chosen speed unit of
U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (-)button once will result in a 1 mph
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.
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
powertrain 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 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 up
hill and down hill. However, a slight speed change on
moderate hills is normal. When driving up hill and
down hill, the ACC system will cancel if the braking
temperature exceeds normal range (overheated).

STARTING AND OPERATING 303

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 Setting 4 Bars (Longest)
Distance Setting 3 Bars (Long)
Distance Setting 2 Bars (Medium)
304 STARTING AND OPERATING

To increase the distance setting, push the Distance Setting
— 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 Setting
— Decrease button and release. Each time the button is
pushed, 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 instrument cluster displays the “Sensed VehicleIndicator” 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.
• 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 instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
Distance Setting 1 Bar (Short)

STARTING AND OPERATING 305

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 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 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 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
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,
the parking brake will be activated, and the ACC system
will be cancelled.

306 STARTING AND OPERATING

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 instrument cluster displays the current ACC system
settings. The instrument cluster display is located in the
center of the instrument cluster. The information it displays
depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button
(located on the steering wheel) until one of the following
displays in the instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”

STARTING AND OPERATING 307

Display 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 instrument cluster display will
show “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
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 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 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 malfunc-
tion.
308 STARTING AND OPERATING

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/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other obstruc-
tion, have the radar sensor realigned at your authorized
dealer.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 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/FCW Limited
Functionality Clean Front Windshield” and the system will
have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 rear view 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/FCW 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 your authorized dealer.
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
6
STARTING AND OPERATING 309

drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your 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.
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.
