2020 CHRYSLER 300 check oil

238SERVICING AND MAINTENANCE
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine
oil must be maintained at the correct level.
Check the oil level at regular intervals, such as
every month. The best time to check the engine
oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings.
There are three possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the
low end of the range and MAX at the high end
of the range.
NOTE:
Always maintain the oil level within the cross -
hatch markings on the dipstick.

Adding 1 quart (1.0 liters) of oil when the reading
is at the low end of the dipstick range will raise
the oil level to the high end of the range marking.

ADDING WASHER FLUID
The windshield washer fluid reservoir is located
in the front of the engine compartment. Be sure
to check the fluid level at regular intervals. Fill
the reservoir with windshield washer solvent
(not radiator antifreeze) and operate the system
for a few seconds to flush out the residual
water.
When refilling the washer fluid reservoir, apply
some washer fluid to a cloth or towel and wipe
the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers. The fluid reservoir will hold nearly 1 gallon
(4 liters) of washer fluid when the message
“Low Washer Fluid” appears in the instrument
cluster.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, nor is periodic maintenance
required.
NOTE:
The battery is stored under an access cover in
the trunk. Remote battery terminals are located
in the engine compartment for jump starting.
Refer to “Jump Starting Procedures” in “In Case
Of Emergency” for further information.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.

242SERVICING AND MAINTENANCE
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air
conditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test. Drive belt tension should also be checked at
this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped
R-134a Air Conditioning Refrigerant is a
hydrofluorocarbon (HFC) that is an
ozone-friendly substance. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer or other
service facilities using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R-1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using
recovery and recycling equipment.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in
the case of engine backfire. Do not remove
the air induction system (air cleaner, hoses,
etc.) unless such removal is necessary for
repair or maintenance. Make sure that no
one is near the engine compartment before
starting the vehicle with the air induction
system (air cleaner, hoses, etc.) removed.
Failure to do so can result in serious personal
injury.
WARNING!
Use only refrigerants and compressor lubri
-
cants approved by the manufacturer for
your air conditioning system. Some unap -
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
Refer to Warranty Information Book, for
further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the 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.
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.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
AUTOMATIC TRANSMISSION
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.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications. It is
important to maintain the transmission fluid at
the correct level using the recommended fluid.
WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” 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 identified on the original factory
installed hydraulic master cylinder reser -
voir.
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 reser -
voir 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 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
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
