2022 CHRYSLER 300 transmission

SERVICING AND MAINTENANCE223
(Continued) Under normal operating conditions, the catalytic
converter will not require maintenance. However, it
is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent
possible catalyst damage.
NOTE:Intentional tampering with emission control
systems can result in civil penalties being
assessed against you. In unusual situations involving grossly
malfunctioning engine operation, a scorching odor
may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn off
the engine and allow it to cool. Service, including a
tune-up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the igni-
tion when the transmission is in gear and the
vehicle is in motion.
Do not try to start the engine by pushing or
towing the vehicle.
Do not idle the engine with any spark plug wires
disconnected or removed, such as when diag
-
nostic testing, or for prolonged periods during
very rough idle or malfunctioning operating
conditions.
NOTE:Your vehicle’s exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system, if
the exhaust system is replaced with aftermarket
products a Malfunction Indicator Lamp (MIL) will
illuminate.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon -
scious and can eventually poison you. To
avoid breathing CO Ú page 191.

A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.

CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.
Damage to the catalytic converter can result if
your vehicle is not kept in proper operating
condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction
could cause the converter to overheat,
resulting in possible damage to the converter
and vehicle.
CAUTION!

reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú
page 269.
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.WARNING!
Use only manufacturer's recommended brake
fluid Úpage 269. 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 identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, 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 contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.

(Continued)
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer's specified
transmission fluid Úpage 269. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
ALL WHEEL DRIVE (AWD) — IF
E
QUIPPED
The All Wheel Drive system consists of a transfer
case and front differential. The exterior surface of
these components should be inspected for
evidence of fluid leaks. Confirmed leaks should be
repaired as soon as possible.
The transfer case fluid fill/inspection plug is
located in the middle of the rear housing. To
inspect the transfer case fluid level, remove the
fill/inspection plug. The fluid level should be even
with the bottom of the hole. Use this plug to add
fluid as required.
The front differential fill plug is located on the outer
cover near the half shaft attachment. To inspect
the differential fluid level, remove the fill plug. The
fluid level should be even with or slightly below the
bottom of the hole.
Fluid Changes
For the proper maintenance intervals Úpage 210.
REAR AXLE
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level Ú page 269.
FUSES
General Information
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Úpage 269.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. 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.

22_LX_OM_EN_USC_t.book Page 228

SERVICING AND MAINTENANCE229
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 Front Power Distribution Center is located in
the engine compartment. This module contains
fuses and relays. Fuse cavity location and
descriptions are printed on the inside of the power
distribution center cover.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
authorized 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.
WARNING!
1 — Fuse Element
2 — Blade Fuse with a good/ functional fuse
element
3 — Blade fuse with a bad/ not functional fuse
element (blown fuse)
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.
