ECU CHRYSLER PACIFICA 2018 Repair Manual

CAUTION!
Driving with a hot cooling system could damage your
vehicle. If temperature gauge reads “H”, pull over and
stop the vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back into the
normal range. If the pointer remains on the “H”, turn
the engine off immediately, and call for service.
MANUAL PARK RELEASE
WARNING!
You should be seated in the driver ’s seat with your foot
firmly placed on the brake pedal to maintain control of
the vehicle before activating the Manual Park Release.
If possible, you should apply the parking brake. Acti-
vating the Manual Park Release will allow your ve-
hicle to roll away if it is not secured or properly
connected to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.
Follow These Steps To Activate The Manual Park Release:
1. Apply firm pressure to the brake pedal while seated in
the driver ’s seat.
2. Apply the parking brake, if possible.

3. Using a small screwdriver or similar tool, remove theManual Park Release access cover, which is to the lower
left of the steering column.
4. The Manual Park Release access cover is connected to a red tether strap. Pull the tether strap out as far as it will
go, then release it. The transmission should now be in
NEUTRAL, allowing the vehicle to be moved.
NOTE: When the lever is locked in the released position,
the tether will remain outside of the trim panel and the
access cover cannot be re-installed.
5. Release the parking brake only when the vehicle is securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Apply firm pressure to the brake pedal while seated in the driver ’s seat.
2. Pull the tether strap out again, then release it.
3. Allow the tether to retract with the lever back to its original position. 4. Verify that the transmission is in PARK.
5. Confirm that the tether has retracted fully and re-install
the access cover. If the access cover cannot be re-
installed, repeat steps 1 through 4.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
NOTE: Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for more
than two seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that will
maintain the rocking motion without spinning the wheels
or racing the engine.

CAUTION!(Continued)
•Be applied parallel to the center line of the length of
the vehicle.
• Not be an abrupt acceleration.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
NOTE: The Safehold feature will engage the Electric Park
Brake whenever the driver’s door is opened (if the ignition

discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK in
order to move the vehicle.
CAUTION!
• Do not use sling-type equipment when towing. Ve-
hicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.

7. Remove the filter cover by prying back each of theretaining tabs from their hooking points, and then
pulling out the filter cover to expose the cabin air filter.
Remove the air filter by pulling it straight out of the
housing.
8. Install the new air filter with the arrow on the filter pointing toward the floor.
CAUTION!
The cabin air filter is identified with an arrow to
indicate airflow direction through the filter. Failure to
properly install the filter will result in the need to
replace it more often.
9. Once the filter is replaced, reinstall the filter cover, making sure the retaining tabs are fully secured into
their housings.
10. Close the cabin air filter compartment cover, and reinsert the snaps into their slots. Push the snap lids
until fully attached. 11. Push the glove compartment door to the near closed
position to reengage the glove compartment travel
stops. Finally, pull the glove compartment tension
tether clip down and slide it back into the slot on the
side of the glove compartment door.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such as
Mopar Spray White Lube to assure quiet, easy operation
and to protect against rust and wear. Prior to the applica-
tion of any lubricant, the parts concerned should be wiped
clean to remove dust and grit; after lubricating excess oil
and grease should be removed. Particular attention should
also be given to hood latching components to ensure
proper function. When performing other underhood ser-
vices, the hood latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.

Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
(Continued)
WARNING! (Continued)
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.

CYBERSECURITY
Your vehicle may be a connected vehicle and may be
equipped with both wired and wireless networks. These
networks allow your vehicle to send and receive informa-
tion. This information allows systems and features in your
vehicle to function properly.
Your vehicle may be equipped with certain security fea-
tures to reduce the risk of unauthorized and unlawful
access to vehicle systems and wireless communications.
Vehicle software technology continues to evolve over time
and FCA US LLC, working with its suppliers, evaluates
and takes appropriate steps as needed. Similar to a com-
puter or other devices, your vehicle may require software
updates to improve the usability and performance of your
systems or to reduce the potential risk of unauthorized and
unlawful access to your vehicle systems.
The risk of unauthorized and unlawful access to your
vehicle systems may still exist, even if the most recent
version of vehicle software (such as Uconnect software) is
installed.
WARNING!
•It is not possible to know or to predict all of the
possible outcomes if your vehicle’s systems are
breached. It may be possible that vehicle systems,
including safety related systems, could be impaired
or a loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• ONLY insert media (e.g., USB, SD card, or CD) into
your vehicle if it came from a trusted source. Media
of unknown origin could possibly contain malicious
software, and if installed in your vehicle, it may
increase the possibility for vehicle systems to be
breached.
• As always, if you experience unusual vehicle behav-
ior, take your vehicle to your nearest authorized
dealer immediately.
