2004 DODGE GRAND CARAVAN oil pressure

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 LED is not lit during starting, have it
checked. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defroster
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 tread and sidewall for cuts or
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 fuel,
engine coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected or fuel, power steering fluid or brake
fluid leaks are suspected, the cause should be located and
corrected immediately.72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
15. Washer Fluid Light
This light turns on when the washer fluid level
falls below approximately 1/4 filled. The light will
remain on until fluid is added.
16. Transmission Range Indicator
This vacuum fluorescent display indicator shows the
automatic transaxle gear selection. 17. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for 4 minutes when this light turns on.
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.
18. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors engine and automatic
transmission control systems. The light will illu-
minate when the key is in the ON position before engine
start. If the bulb does not come when turning the key
from OFF to ON, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after UNDERSTANDING YOUR INSTRUMENT PANEL 155

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!² 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. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
² The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.282 WHAT TO DO IN EMERGENCIES

The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground 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.
CAUTION!Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.304 MAINTAINING YOUR VEHICLE

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE: Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before hose is re-
placed based on leakage.
NOTE: Inspection of brake hoses should be performed
whenever the brake system is serviced and every engine
oil change. Inspect hydraulic brake hoses for surface
cracking, scuffing, or worn spots. If there is any evidence
of cracking, scuffing, or worn spots, the hose should be replaced immediately! Eventual deterioration of the hose
can take place resulting in a possibility of a burst failure.
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.
Master Cylinder Ð ABS Brakes Brake Fluid Level
Check
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning light indicates system failure.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
ªFULLº mark on the side of the master cylinder reservoir.324 MAINTAINING YOUR VEHICLE

² Taxi, police, or delivery service (commercial ser-
vice). L
² Off-road or desert operation.
NOTE: Most vehicles are operated under the conditions
listed for Schedule 9 B 9 .
Second is Schedule ªAº . It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule 9 B 9 .
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
CAUTION!Failure to perform the required maintenance items
may result in damage to the vehicle. At Each Stop for Fuel
² Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
² Check the windshield washer solvent and add if
required.
Once a Month
² Check tire pressure and look for unusual wear or
damage.
² Inspect the battery and clean and tighten the terminals
as required.
² Check the fluid levels of coolant reservoir, brake
master cylinder and transmission; add as needed.
² Check all lights and all other electrical items for correct
operation. MAINTENANCE SCHEDULES 349
