2004 CHRYSLER 300 M oil pressure

must remain open, close all windows. Adjust the
heating or cooling system to force outside air into the
vehicle. Set the blower at high speed.
Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Safety belt assemblies must be replaced after an accident
if they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Light
The light should come on and remain on for 6 to
8 seconds as a bulb check when the ignition
switch is first turned ON. If the bulb is not lit
during starting, have it replaced. If the light stays on or
comes on while driving, have the system checked by an
authorized dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for
brake fluid, fuel, water, oil, or other fluid leaks. Also, if
gasoline fumes are present, the cause should be corrected
immediately.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTION
1. Fuel Gauge
When the ignition is in the ON position, the
pointer will show the level of fuel remaining in
the tank.
2. Low Fuel Warning Light
When the fuel level drops to about 2 gallons (8
liters), the Low Fuel symbol will light and re-
main lit until fuel is added. A warning chime will
sound when the light comes on.
3. Low Oil Pressure Light
This light indicates low engine oil pressure. The
light should come on briefly as a bulb check
when the engine is first started. If the light stays on or
comes on while driving, stop the vehicle and shut off
the engine. DO NOT operate the vehicle until the
cause is corrected.This light does not show how
much oil is in the engine.The engine oil level must be
checked under the hood.4. TRAC ON/OFF Lights
The Traction Control On light (TRAC ON) will come on
momentarily as a bulb check when the ignition switch is
first turned ON. If the light does not come on, have the
bulb replaced.
The TRAC ON light will also come on when the system
is controlling traction.
The Traction Control Off light (TRAC OFF) will come on
momentarily as a bulb check when the ignition switch is
first turned ON. If the light does not come on, have the
bulb checked.
The TRAC OFF light will come on when the Traction
Control switch has been used to turn the system off.
5. Trunk Ajar Light
This light indicates that the trunk is not latched
6. Tachometer
Measures engine revolutions-per-minute (R.P.M.). The
red numbers at the end on the scale show the maximum
permissible R.P.M. Ease off on the accelerator before
reaching the red area.

the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
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 conditioner 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.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
WHAT TO DO IN EMERGENCIES 183
6

•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.

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking,
checking, tears, cuts, abrasion, and excessive swelling
suggest deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master CylinderThe fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.
MAINTAINING YOUR VEHICLE 219
7

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. However, low
fluid level may be caused by a leak and a checkup may be
needed.
Use only the manufacturer’s recommended brake fluid.
Refer to the Recommended Fluids, Lubricants and Genu-
ine Parts section for the correct fluid type.WARNING!
Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
Do not allow petroleum base fluid to contaminate the
brake fluid as seal damage will result!
Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses and clamps which have unique
material characteristics to provide adequate sealing and
resist attack by deteriorated gasoline.
You are urged to use only the manufacturer specified
hoses and clamps, or their equivalent in material and
specification, in any fuel system servicing. It is manda-
tory to replace all clamps that have been loosened or
removed during service. Care should be taken in install-
ing new clamps to insure they are properly torqued.
