2023 CHRYSLER PACIFICA HYBRID engine

STARTING AND OPERATING115
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the
recommended viscosity and quality grades
Úpage 264.
NOTE:A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers simple
operation, and some additional features that make the
parking brake more convenient and useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the
vehicle, make sure that the parking brake is applied. Also,
be certain to leave the transmission in PARK. You can engage the parking brake in two ways;

Manually, by applying the EPB switch.
 Automatically, by enabling the Auto Park Brake feature
in the customer programmable features
Úpage 158.
The EPB is located in the integrated center stack.

Electric Park Brake Switch

To apply the parking brake manually, push the switch
momentarily. You may hear a sound from the back of the
vehicle while the parking brake engages. Once the parking
brake is fully engaged, the Brake Warning Light in the
instrument cluster and an indicator on the switch will
illuminate. If your foot is on the brake pedal while you
apply the parking brake, you may notice a small amount of
brake pedal movement. The parking brake can be applied
even when the ignition switch is OFF, however, it can only
be released when the ignition switch in the ACC or ON/
RUN position.
NOTE:The EPB Warning Light will illuminate if the EPB switch is
held for longer than 180 seconds. The light will extinguish
upon releasing the switch.
If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the
transmission is placed into PARK. Once the parking brake
is engaged, the Brake Warning Light in the instrument
cluster and the LED indicator on the switch will illuminate.
If your foot is on the brake pedal, you may notice a small
amount of brake pedal movement while the parking brake
is engaging.
The parking brake will release automatically when the
ignition is cycled to the ON/RUN position, the transmission
is in DRIVE or REVERSE, and the driver seat belt is buckled
and an attempt is made to drive the vehicle away by
pressing the accelerator pedal.
To release the parking brake manually, the ignition switch
must be in the ON/RUN position. Press on the brake
pedal, then push the parking brake switch momentarily.
You may hear a sound from the back of the vehicle while
the parking brake disengages. You may also notice a small
amount of movement in the brake pedal. Once the parking
brake is fully disengaged, the Brake Warning Light in the
instrument cluster and the LED indicator on the switch will
extinguish.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

Brake Service Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Service Mode during brake
service.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the Electric Park Brake (EPB) system,
this can only be done after retracting the EPB actuator.
Fortunately, actuator retraction can be done easily by
entering Brake Service in your vehicle
Úpage 158. This
menu-based system will guide you through the steps
necessary to retract the EPB actuator in order to perform
rear brake service.
Brake Service has requirements that must be met in order
to be activated:
 The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK or NEUTRAL.
While in Brake Service, the EPB Warning Light will flash
continuously while the ignition switch is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
 Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the trans -
mission gear selector out of PARK with the brake
pedal released. Make sure the transmission is in
PARK before exiting the vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.

 It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is firmly
pressing the brake pedal.

 Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When exiting the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle, and lock the 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 seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
WARNING!

118STARTING AND OPERATING
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF position. 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 position.
NOTE:The transmission is NOT locked in PARK when the ignition
is in the ACC position (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition
is OFF (not in ACC position) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the brakes are
applied. To shift the transmission out of PARK, the engine
must be running 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.
9-SPEED AUTOMATIC TRANSMISSION
The transmission is controlled using a rotary electronic
gear selector located on the center console. The
transmission gear selector has PARK, REVERSE,
NEUTRAL, DRIVE, and LOW shift positions. Using the LOW
position manually downshifts the transmission to a lower
gear based on vehicle speed. The transmission gear range
(PRNDL) is displayed both above the gear selector and in
the instrument cluster. 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 transmission out of
PARK (or NEUTRAL, when stopped or moving at low
speeds). 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.
NOTE:In the event of a mismatch between the gear selector
position and the actual transmission gear (for example,
driver selects PARK while driving), the position indicator
will blink continuously until the selector is returned to the
proper position, or the requested shift can be completed.
The electronically controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
The 9-speed transmission has been developed to meet
the needs of current and future FWD/AWD vehicles.
Software and calibration is refined to optimize the
customer’s driving experience and fuel economy. By
design, some vehicle and driveline combinations utilize
NINTH gear only in very specific driving situations and
conditions.
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when shifting
between these gears.

Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN position. A child
could operate power windows, other controls, or
move the vehicle.
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.
 Do not shift between PARK, REVERSE, NEUTRAL, or
DRIVE when the engine is above idle speed.
 Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
WARNING!

Transmission Gear Selector

GEAR RANGES
Do not press the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to allow the
selected gear to engage before accelerating. This is espe -
cially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade. When exiting the vehicle, always:

Apply the parking brake.
 Shift the transmission into PARK.
 Turn the ignition off.
 Remove the key fob from the vehicle.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
 Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
 With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift the
transmission into PARK if you must exit the vehicle.CAUTION!
Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
 DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range, as this can
damage the drivetrain.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

120STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteristics
under all normal operating conditions.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light will illuminate, a
warning message will appear in the instrument cluster,
and the transmission may operate differently until the
transmission cools down.

During cold temperatures, transmission operation may be
modified depending on engine and transmission temperature
as well as vehicle speed. This feature improves warm-up time
of the engine and transmission to achieve maximum efficiency.
Engagement of the torque converter clutch, and shifts into
EIGHTH or NINTH gear, are inhibited until the transmission fluid
is warm

Ú
page 120. Normal operation will resume once the
transmission temperature has risen to a suitable level.

LOW (L)
Use this range for engine braking when descending very
steep grades. In this range, the transmission will
downshift for increased engine braking. To access the
LOW position, push down on the gear selector and rotate
it fully clockwise.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer
service is required.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage until the
engine and/or transmission is warm (usually after 1 to
3 miles [2 to 5 km] of driving). Because the engine speed
is higher when the torque converter clutch is not engaged,
it may seem as if the transmission is not shifting properly
when the vehicle is cold. This is normal. The torque
converter clutch will function normally once the powertrain
is sufficiently warm.
ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This feature provides on-demand All-Wheel Drive (AWD).
The system is automatic with no driver inputs or additional
driving skills required. Under normal driving conditions,
the front wheels provide most of the traction. If the front
wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a preemptive effort to improve vehicle launch
and performance characteristics.

23_RUP_OM_EN_USC_t.book Page 120

STARTING AND OPERATING121
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancellation
system. This system is designed to address exhaust and
engine noise. The system relies on four microphones
embedded in the headliner, which monitor exhaust and
engine noise, and assists an onboard frequency
generator, which creates counteracting sound waves in
the audio system’s speakers. This helps keep the vehicle
quiet at idle and during drive.
POWER STEERING
The electric power steering system will provide increased
vehicle response and ease of maneuverability. The power
steering system adapts to different driving conditions. If the Steering icon is displayed and the “Power Steering
System Over Temp” message is displayed on the
instrument cluster screen, this indicates an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle
idle for a few moments until the icon and message turn off
Úpage 102.
If the “Service Power Steering" or "Power
Steering Assist Off - Service System” message
and a steering wheel icon are displayed on the
instrument cluster screen, it indicates that the
vehicle needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power steering
assistance
Úpage 102.
NOTE:
 Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 The power steering system is fully electric; it requires
no power steering fluid.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed 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.
AUTOSTOP MODE
The Stop/Start feature is enabled after every driver key
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
Úpage 102.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed.
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.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause premature wear of the driveline
components.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
