2023 CHRYSLER PACIFICA check engine

SERVICING AND MAINTENANCE275
(Continued)
NOTE:No chemical flushes should be used in any transmission;
only the approved lubricant should be used.
FUSES
General Information
The fuses protect electrical systems against excessive
current.
When a device does not work, you must check the fuse
element inside the blade fuse for a break/melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may result in
vehicle battery discharge.

Blade Fuses

Underhood Fuses
The Power Distribution Center (PDC) is located in the
engine compartment near the battery. This center
contains cartridge fuses, mini-fuses, micro-fuses, circuit
breakers and relays. A label that identifies each
component is printed on the inside of the cover.
Before any procedure is done on the PDC, make sure
engine is turned off.
Remove the cover by unlatching the two locks located at
each side of the PDC cover, avoid using screwdrivers or
any other tool to remove the cover, since they may apply
excessive force and result in a broken/damaged part.
After service is done, secure the cover with its two locks.
NOTE:The function and amperage of the following fuses are
different, depending on vehicle trim level and content.
CAUTION!
Using a transmission fluid other than the manufacturer
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder
Úpage 307.
WARNING!
When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. Failure to use proper fuses may result in
serious personal injury, fire and/or property damage.
 Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
 If the replaced fuse blows again, contact an autho -
rized dealer.
 If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.

2 — Blade Fuse with a good/functional fuse element
3 — Blade Fuse with a bad/not functional fuse element
(blown fuse)
WARNING!
CAUTION!
When installing the power distribution center cover, it is
important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to get
into the power distribution center and possibly result in
an electrical system failure.

304TECHNICAL SPECIFICATIONS
Tighten the lug nuts/bolts in a star pattern until each nut/
bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Patterns

After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see a dealer
immediately. Use of gasoline with a lower than
recommended octane number can cause engine failure
and may void or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before
considering service for the vehicle.
3.6L ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emissions
regulations and provide optimum fuel
economy and performance when using high
quality unleaded regular gasoline having a
posted octane number of 87 as specified by
the (R+M)/2 method. The use of higher octane premium
gasoline is not required, as it will not provide any benefit
over regular gasoline in these engines.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
Reformulated gasoline contains oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the Malfunction Indicator Light to
illuminate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than
15% ethanol (E-15).
