service CHRYSLER PACIFICA 2018 Service Manual

NOTE:
•The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized Mopar dealer.
• The engine block heater will require 110 Volts AC and 6.5
Amps to activate the heater element.
• The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable. While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
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 recom-
mended viscosity and quality grades, refer to “Dealer
Service” in “Servicing And Maintenance”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
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
interpreted as a problem.
312 STARTING AND OPERATING

WARNING!(Continued)
touch the parking brake, brake pedal or the trans-
mission 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 in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
• Driving the vehicle with the parking brake engaged,
or repeated use of the parking brake to slow the
vehicle may cause serious damage to the brake
system.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
If exceptional circumstances should make it necessary to
engage the park brake while the vehicle is in motion, push
on the electric park brake switch for as long as engagement
is desired. The BRAKE warning lamp will illuminate, and
a continuous chime will sound. The rear stop lamps will
also be illuminated automatically while the vehicle re-
mains in motion.
To disengage the park brake while the vehicle is in motion,
release the switch. If the vehicle is brought to a complete
stop using the park brake, when the vehicle reaches
approximately 3 mph (4.8 km/h), the park brake will
remain engaged.
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault lamp will illuminate. This
may be accompanied by the BRAKE warning lamp flash-
ing. In this case, urgent service of the electric park brake
system is required. Do not rely on the park brake to hold
the vehicle stationary.

STARTING AND OPERATING 315

Auto Park Brake
The Electric Park Brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and
the automatic transmission is placed in PARK. Auto Park
Brake is enabled and disabled by customer selection
through the “Customer Programmable Features” section of
the “Uconnect Settings”.
SafeHold
SafeHold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if the
vehicle is left unsecured. If the automatic transmission is
not in PARK, the seat belt is unbuckled, the driver door is
open, the vehicle is at a standstill, and there is no attempt
to depress the brake pedal or accelerator pedal, the park
brake will automatically engage to prevent the vehicle
from rolling.
SafeHold can be temporarily bypassed by pushing the
Electric Park Brake Switch while the driver door is open
and brake pedal is pressed. Once manually bypassed,
SafeHold will be enabled again once the vehicle reaches
12 mph (20 km/h) or the ignition is cycled to the OFF
position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by your
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 ser-
vice.
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 system, this can
only be done after retracting the Electric Park Brake
actuator. Fortunately, actuator retraction can be done easily
by entering the “Brake Service” through the “Uconnect
Settings” in your vehicle. 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 Mode has requirements that must be met in
order to be activated:
•The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp
will flash continuously while the ignition switch is ON.
316 STARTING AND OPERATING

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 Electric Park Brake Switch.
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.
AUTOMATIC TRANSMISSION
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.
(Continued)
WARNING! (Continued)
•Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission 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 ve-
hicle 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 posi-
tion is properly 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 re-
verse. 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

STARTING AND OPERATING 317

Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal 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 trans-
mission.
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, shiftthe 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 recom-
mend 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
324 STARTING AND OPERATING

converter clutch will function normally once the pow-
ertrain is sufficiently warm.
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 give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that extreme steer-
ing maneuvers may have occurred which caused 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.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. 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 the dealer for
service. It is likely the vehicle has lost power steering
assistance. Refer to “Warning Lights And Messages” in
“Getting To Know Your Instrument Panel” for further
information.

STARTING AND OPERATING 325

NOTE:
•Even if the power steering assistance is no longer
operational, 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 your authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel con-
sumption. 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.
326 STARTING AND OPERATING

4. The STOP/START system will reset itself back to an ONcondition 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 while exiting. These interior warn-
ings will occur regardless of whether the key fob re-
mains in the vehicle or is removed.
• For the exterior of the vehicle, the horn will sound three
times if the fob is removed from the vehicle and the
vehicle is in the “READY” mode.
Please consider this feature when intentionally running the
vehicle for extended periods of time over one hour. To
restart the vehicle, follow the normal vehicle starting
process. NOTE:
If the vehicle is left in the ACC or RUN (engine not
running) position and the transmission is in PARK, the
system will automatically time out (shut down) after an
initial 30 minutes of inactivity, followed by the additional
amount of time for power accessory delay selected in the
radio settings menu. Once the vehicle times out, it will
switch to the OFF position.
To Manually Turn On The Stop/Start System
After turning off the STOP/START system, push the
STOP/START OFF switch again (located on the instrument
panel). The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display and the Stop/Start telltale will remain
yellow. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system checked
by your authorized dealer.

“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. 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.
344 STARTING AND OPERATING

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
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.
Towing A Trailer
Towing a trailer is not advised when using ACC.
