CHRYSLER 300 M 2004 1.G Owners Manual

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 proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain the maintenance service
recommended by the engineers who designed your ve-
hicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained, at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
MAINTAINING YOUR VEHICLE 201

The best time to check the oil level is about 5 minutes
after a fully warmed up engine is shut off or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings.
Maintain the oil level between the MIN and MAX
markings on the dipstick. Adding one quart of oil when
the reading is at the MIN mark will result in a MAX
reading on these engines.
Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
•Day or night temperatures are below 32°F (0°C)
•Stop and go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trips of less than 10 miles (16.2 km)
202 MAINTAINING YOUR VEHICLE

•More than 50% of your driving is at sustained high
speeds during hot weather above 90°F (32°C)
•Trailer towing
•Taxi, police or delivery service (commercial service)
•Off road or desert operation
•If equipped for and operating with E —85 (ethanol)
fuel
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
NOTE:Under no circumstances should oil change
intervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, we only recommend en-
gine oils that are API Certified and meet the requirements
of DaimlerChrysler Material Standard MS-6395. Use Mo-
par or an equipvalent oil meeting the specification MS-
6395.

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). We
only recommend API Certified en-
gine oils that meet the require-
ments of DaimlerChrysler’s Mate-
rial Standard MS-6395. Use Mopar
or an equivalent oil meeting the
specification MS-6395.
NOTE:SAE 10W-30 engine oil is preferred for use in
3.5L Engines within the operating temperatures shown in
the viscosity chart. SAE 5W-30 Engine Oil is allowed for
use in the 3.5L Engine during cold weather only to
improve cold weather starting.
Engine Oil Viscosity Chart
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the engine oil
viscosity chart.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
204 MAINTAINING YOUR VEHICLE

performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of the manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts — Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the mileage specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.

Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you
drive the vehicle frequently under dusty or severe con-
ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
Schedule “B”.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner 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 cleaner removed. Failure to do so can result in
serious personal injury.
Engine Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent replacement of the fuel filter which is mounted
in the fuel tank may be necessary. See your dealer for
service.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly serviced to assure
proper catalyst operation and prevent possible catalyst
damage. If the Malfunction Indicator light is flashing,
immediate service is required.
206 MAINTAINING YOUR VEHICLE

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
WARNING!
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 ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
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 specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transaxle is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
MAINTAINING YOUR VEHICLE 207

replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Maintenance-Free Battery
The top of the MAINTENANCE-FREE battery is perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:The battery is stored in a compartment in front
of the tire in the right front fender and is accessible
through the engine compartment. The tire and wheel
need not be removed to access the battery.
To access the battery:
1. Turn the steering wheel fully to the right.
2. Remove the battery access panel from the inner fender
shield.
3. Remove the air cleaner.
4. Remove the battery tie down bracket.
5. Move the battery into the opening and lift it out.
WARNING!
Battery fluid is a corrosive acid solution and can
burn or even blind you. Don’t allow battery fluid to
contact your eyes, skin or clothing. Don’t lean over a
battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with
large amounts of water. Battery gas is flammable and
explosive. Keep flame or sparks away from the
battery. Don’t use a booster battery or any other
booster source with an output greater than 12 volts.
Don’t allow cable clamps to touch each other.
WARNING!
Battery posts, terminals and related accessories con-
tain lead and lead compounds. Wash hands after
handling.
208 MAINTAINING YOUR VEHICLE

CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and identified on the battery case.
Cable clamps should be tight on the terminal posts
and free of corrosion. Apply grease to posts and
clamps after tightening. If a “fast charger” is used
while the battery is in the vehicle, disconnect both
vehicle battery cables before connecting the charger
to battery. Do not use a “fast charger” to provide
starting voltage as battery damage can result.
Air Conditioner
Check the air conditioning system at the start of the
warm weather season.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator andthrough the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
WARNING!
The air conditioning system contains refrigerant
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 repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere, the manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recyling and recovery equipment that meets
SAE standard J1991.

Power Steering Fluid Check
WARNING!
Fluid level should be checked with the engine off to
prevent injury from moving parts. Do not overfill.
Use only the manufacturer’s recommended power
steering fluid. Refer to Recommended Fluids, Lubri-
cants and Genuine Parts for the correct fluid type.
During scheduled maintenance, check the power steering
fluid level at the power steering fluid reservoir.
Before removing the reservoir cap, wipe the outside of
the cap and reservoir so that no dirt can fall into the
reservoir.
Fluid level should be maintained at the proper level
indicated on the side of the reservoir. If necessary, add
fluid to restore to the proper indicated level. With a clean
cloth, wipe any spilled fluid from all surfaces. See your
dealer or the Recommended Fluids, Lubricants and
Genuine Parts section in this manual for the correct
power steering fluid for your vehicle.
