2004 DODGE GRAND CARAVAN fuel 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

When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly underin-
flated. You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the tire and loading information placard.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability.
Each tire, including the spare, should be checked
monthly when cold and set to the recommended inflation
pressure as specified in the tire and loading information
placard and owner's manual. 24. Turn Signal Indicators Ð Base Cluster Only
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
25. High Beam Light Ð Base Cluster Only
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low
beam.158 UNDERSTANDING YOUR INSTRUMENT PANEL

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on either the face of the driver's door or the
driver's side ªBº pillar. For vehicles other than passenger
cars, the cold tire inflation pressures are listed on either
the ªBº pillar, the Certification Label or in the Tire
Inflation Pressures brochure in the glove compartment. Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less that the maxi-
mum loaded vehicle condition. These pressure condi-
tions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
ªBº PILLAR252 STARTING AND OPERATING

WARNING!² Remove the fuel tank filler tube cap (gas cap) slowly
to prevent fuel spray from the filler neck which may
cause injury.
² The volatility of some gasolines may cause a buildup
of pressure in the fuel tank that may increase while
you drive. This pressure can result in a spray of
gasoline and/or vapors when the cap is removed
from a hot vehicle. Removing the cap slowly allows
the pressure to vent and prevents fuel spray.
² Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank
filled.
² Never add fuel to the vehicle when the engine is
running.
² A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling. VEHICLE LOADING
The load carrying capacity of your vehicle is shown in the
charts that follow. This information should be used for
passenger and luggage loading as indicated.
If seats are removed for carrying cargo, do not exceed the
specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a certification label attached to the
driver's door pillar.
The label contains the following information:
² Name of manufacturer
² Month and year of manufacture
² Gross Vehicle Weight Rating (GVWR)
² Gross Axle Weight Rating (GAWR) front
² Gross Axle Weight Rating (GAWR) rear272 STARTING AND OPERATING

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 manufacturers 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.
Automatic Transmission
The automatic transmission and differential assembly are
contained within a single housing.
All automatic transmissions are equipped with a conven-
tional filler tube and dipstick. If fluid is added, it should
be added through the dipstick hole in the case. The dipstick is located just behind the radiator, lower
right side.
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturers recommended transmis-
sion fluid, refer to Recommended Fluids, Lubricants and
Genuine Parts for correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid.326 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
