2020 CHRYSLER PACIFICA HYBRID brake

STARTING AND OPERATING235
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the
engine automatically during a vehicle stop if the
required conditions are met. Releasing the
brake pedal, pressing the accelerator pedal or
shifting out of DRIVE (D) will automatically
re-start the engine.
This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other
upgraded engine parts to handle the additional
engine starts.
Auto Stop/Start
The Stop/Start feature is enabled
after every normal customer engine
start. At that time, the system will go
into STOP/START READY and if all
other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE.
To Activate Auto STOP/START, The Following
Must Occur:
The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster within the Stop/Start section. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
The vehicle must be completely stopped.
The shifter must be in a forward gear and the
brake pedal depressed.
The engine will shut down, the tachometer will
move to the zero position and the Stop/Start
telltale will illuminate indicating you are in
Autostop. Customer settings will be maintained
throughout the Auto Stop/Start process.
Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will check
many safety and comfort conditions for Stop/
Start and ensure they are fulfilled. Detailed
information about the operation of the Stop/
Start system may be viewed in the instrument
cluster display Stop/Start screen. In the
following situations the engine will not stop:
If Stop/Start is manually disabled by the
Stop/Start OFF button.
Driver’s seat belt is not buckled.
Driver’s door is not closed.
Battery temperature is too warm or cold.
Battery charge is low. During this time a
message will display "Stop/Start Not Ready
Battery Charging".
The vehicle is on a steep grade.
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved.
HVAC is set to full defrost mode at a high
blower speed.
HVAC set to MAX A/C.
Engine has not reached normal operating
temperature.
The transmission is not in a forward gear.
Hood is open.
Brake pedal is not pressed with sufficient
pressure.

236STARTING AND OPERATING
Other Factors Which Can Inhibit Autostop
Include:
Accelerator pedal input.
Engine temp too high.
5 mph (8 km/h) threshold not achieved from
previous AUTOSTOP.
Steering angle beyond threshold.
ACC is on and speed is set.
It may be possible for the vehicle to be driven
several times without the Stop/Start system
going into a Stop/Start READY state under more
extreme conditions of the items listed above.
To Start The Engine While In Auto Stop/Start
While in a forward gear, the engine will start
when the brake pedal is released or the throttle
pedal is depressed. The transmission will
automatically re-engage upon engine restart.
Conditions That Will Cause The Engine To Start
Automatically While In Auto Stop/Start:
The transmission selector is moved out of
DRIVE.
To maintain cabin temperature comfort.
HVAC is set to full defrost mode.
HVAC system temperature or fan speed is
manually adjusted.
Battery voltage drops too low. During this
time a message will display "Stop/Start Not
Ready Battery Charging".
Low brake vacuum (e.g. after several brake
pedal applications).
Stop/Start OFF switch is pushed.
A Stop/Start system error occurs.
To Manually Turn Off The Stop/Start System

Stop/Start OFF Button
1. Push the Stop/Start OFF switch (located on
the instrument panel). The light on the
switch will illuminate.

2. The “STOP/START OFF” message will appear in the instrument cluster display.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”
for further information.
3. At the next vehicle stop (after turning off the Stop/Start system) the engine will not be
stopped.
4. The Stop/Start system will reset itself back to an ON condition every time the ignition is
turned off and back on.
Automatic Shutdown
This vehicle is equipped with an automatic
shutdown feature. If the vehicle is left in READY
mode (vehicle running) with the gear selector in
PARK for one hour after the driver exits, this
feature will automatically turn the vehicle off.
Notifications have been added into this feature
to raise awareness of the timed event:In the interior of the vehicle, the instrument
cluster will display “Ready To Drive”, and will
be accompanied by three audible chimes

To Decrease Speed
When the Speed Control is set, you can
decrease speed by pushing the SET (-) button.
The driver’s preferred units can be selected
through the instrument panel settings. Refer to
”Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed increment shown is
dependent 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 subse -
quent tap of the button results in a decrease
of 1 mph.
If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established. Metric Speed (km/h)
Pushing the SET
(-) button once will result in
a 1 km/h decrease in set speed. Each subse -
quent 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 until the
button is released, then the new set speed
will be established.
To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
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).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Speed
Control without erasing the set speed from
memory. Pushing the on/off button or placing the ignition
in the OFF position erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions.
Speed
Control function performs differently. Please
refer to the proper section within this chapter.
ACC will allow you to keep cruise control
engaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a
vehicle directly ahead of you.
5

20_RU_OM_EN_US_t.book Page 239

240STARTING AND OPERATING
(Continued)
NOTE:

If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
The Cruise Control system has two control
modes:
Adaptive Cruise Control mode for maintaining
an appropriate distance between vehicles.
Normal (Fixed Speed) Cruise Control mode for
cruising at a constant preset speed. For addi -
tional information, refer to “Normal (Fixed
Speed) Cruise Control Mode” in this section.

NOTE:
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 confirm which mode
is selected.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake opera -
tion to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle.
Failure 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
limited upon adverse sight distance
conditions.
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 approximately 3 minutes
in the stop position. If the target vehicle
does not start moving within 3 minutes
the parking brake will be activated, and
the ACC system will be cancelled.
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 construc -
tion 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.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.

(resume) button and then remove your foot
from the accelerator pedal. The instrument
cluster display will display the last set speed.
NOTE:
If your vehicle stays at standstill for longer
than two seconds, then 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.
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 Speed
While ACC is set, you can increase the set speed
by pushing the SET (+) button.
The driver's preferred units can be selected
through the instrument cluster. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed increment shown is
dependent 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 increase in set speed. Each subse -
quent tap of the button results in an increase
of 1 mph.
If the button is continually pushed, 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
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.

Metric Speed (km/h)
Pushing the SET (+) button once will result in
a 1 km/h increase in set speed. Each subse -
quent 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
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 instrument cluster. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed decrement shown is
dependent 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 subse -
quent 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 subse -
quent 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 decel
-
erate, if the powertrain braking power does
not slow the vehicle sufficiently to reach the
set speed, the brake system will automati -
cally 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. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving up hill and down hill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).

20_RU_OM_EN_US_t.book Page 244

246STARTING AND OPERATING
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 infor -
mation on ACC Activation).
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.
Brake Alert

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
If the ACC system brings your vehicle to a
standstill while following a target vehicle, your
vehicle will resume motion, without any driver
interaction, if the target vehicle starts moving
within two seconds.
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. The vehicle will
accelerate to the existing set speed.
NOTE:
After the ACC system holds your vehicle at a
standstill 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 seatbelt is unbuckled or
the driver door is opened, the parking brake will
be activated, and the ACC system will be
cancelled.
