battery CHRYSLER PACIFICA HYBRID 2019 Service Manual

Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Battery Charge Warning Light
This warning light illuminates when the 12 volt battery is
not charging properly. If it stays on while the vehicle is
running, there may be a malfunction with the charging
system. Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condi-
tion. If the engine coolant temperature is too high, this
indicator will illuminate and a single chime will sound. If
the temperature reaches the upper limit, a continuous
chime will sound for four minutes or until the engine is
able to cool: whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “In Case Of
Emergency” for further information.
— Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to indicate a problem
with the Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is running, the light
will either stay on or flash depending on the nature of the
problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed in the
PARK position. The light should turn off. If the light

For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen: •
The MIL will flash for about ten seconds and then return
to being fully illuminated until you turn OFF the igni-
tion or start the engine. This means that your vehicle’s
OBD II system is not readyand you should notproceed
to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off posi-
tion or start the engine. This means that your vehicle’s
OBD II system is readyand you can proceed to the I/M
station.
If your OBD II system is not ready,you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the above test routine may then
indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.

Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Regenerative Braking System (RBS) — Hybrid
Your vehicle has a Regenerative Braking System (RBS). The
RBS replenishes the vehicle’s high voltage battery during
deceleration, and is particularly useful in stop-and-go city
traffic. The electric motors which propel the vehicle for-
ward can operate as generators when braking. The RBS
recharges the high voltage battery under certain braking
conditions by recapturing energy that would otherwise belost while braking. The electric power that is generated
goes back into the high voltage battery for later use, for
example when acceleration is desired.
The RBS uses conventional hydraulic friction brakes, re-
generative braking, or a combination to slow the vehicle. If
the system detects slippery conditions while braking,
ONLY friction is used to slow the vehicle. The RBS can
result in extended life of the hydraulic service brakes;
however, all inspection, scheduled maintenance, and ser-
vice intervals for the vehicle service brakes must be fol-
lowed.
Audible Pedestrian Warning System
Your vehicle is equipped with an Audible Pedestrian
Warning System. The Audible Pedestrian Warning System
uses distinct sounds to alert pedestrians that your vehicle is
approaching. In addition, the module will indicate change
in speed by varying the pitch of sound.
The audible warning system uses an in-car sound synthe-
sizer with a speaker located in the underhood compart-
ment. The warning system is automatically activated when
selecting REVERSE, NEUTRAL, DRIVE or LOW.

Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the
ACC position, the air bag system is not on and the air bags
will not inflate. The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing Light will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A single chime
will sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer service the air
bag system immediately.

• Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment. •
After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine whether
to have the Enhanced Accident Response System perform
the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as
the battery has power or for 15 minutes from the
intervention of the Enhanced Accident Response Sys-
tem.
• Unlock the power door locks.
Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:

STARTING THE VEHICLE
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
•When exiting the vehicle, always remove the key fob
from the vehicle and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the transmission gear selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death. Request Propulsion System Active (PSA) or “Vehicle is
Ready to Drive” mode with the gear selector in the PARK
position. Apply the brake before shifting to any driving
range.
NOTE:
In case the ignition switch does not change with the
push of a button, the key fob may have a low or dead
battery. In this situation, a back up method can be used to
operate the ignition switch. Put the nose side of the key fob
(side opposite of the Emergency Key) against the ENGINE
START/STOP button and push to operate the ignition
switch.

STARTING AND OPERATING 287

CAUTION!(Continued)
•Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal with the exception of
shifting between Drive and Low. Shifting between
Drive and Low can occur without any brake applica-
tion.
To Turn On The Engine Using ENGINE START/STOP
Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
To release the parking brake manually, the ignition switch
must be in the ON/RUN position. Press on the brake
pedal, then push the park brake switch momentarily.
If the driver shifts into PARK while moving, the vehicle
may Park.
Park will engage ONLYwhen vehicle speed is 1.2 MPH
(1.9 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to P”
will display in the Instrument Cluster Display if vehicle
speed is above 1.2 MPH (1.9 km/h). The gear position indicator will blink continuously until the selector is re-
turned to the proper position, or the requested shift can be
completed.
WARNING!
If vehicle speed is not below 1.2 MPH (1.9 km/h) when
the driver shifts into PARK, the transmission will
default to NEUTRAL until the vehicle speed drops
below 1.2 MPH (1.9 km/h) and the above condition are
met, enabling AutoPark. A vehicle left in the NEU-
TRAL position can roll. As an added precaution, al-
ways apply the parking brake when exiting the ve-
hicle.
Cold Weather Operation
If the outside ambient temperature is 5°F (-15°C) or below,
the instrument cluster will request the vehicle to be
plugged in to provide conditioning of the vehicle high
voltage battery.
NOTE:
“Electric Only” mode may have reduced availabil-
ity in colder ambient temperatures due to HVAC demand.

STARTING AND OPERATING 291

CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
•Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
•
Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal with the exception of
shifting between Drive and Low. Shifting between
Drive and Low can occur without any brake application.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Ignition Park Interlock
Your vehicle is equipped with a Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode.
Brake/Transmission Shift Interlock System
Your vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the ignition must be in the
ON/RUN mode (engine running or not) and the brake
pedal must be pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or REVERSE
when the vehicle is stopped or moving at low speeds.
Hybrid Transmission
The transmission is controlled using a rotary electronic
gear selector located on the center console. The transmis-
sion gear selector has PARK, REVERSE, NEUTRAL,
DRIVE, and LOW shift positions. Using the LOW position
will increase the rate of deceleration along with increasing
regeneration of power into the vehicle’s High Voltage (HV)
battery (in comparison to the DRIVE position). The trans-
mission gear range (PRNDL) is displayed both above the
gear selector and in the instrument cluster display. To select
a gear range, simply rotate the gear selector. Push down on
the gear selector, and then rotate it, to access the L position.
You must also press the brake pedal to shift the transmis-
sion out of PARK (or NEUTRAL, when the vehicle is
stopped). To shift past multiple gear ranges at once (such as
PARK to DRIVE), simply rotate the gear selector to the
appropriate detent. Select the DRIVE range for normal
driving.
