2005 DODGE GRAND CARAVAN engine oil

While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty. SAFETY TIPS
Exhaust Gas
WARNING!Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in or
out of the area.
If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 83

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. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 85

CAUTION!Driving with a hot engine 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 ” , and you hear continuous chimes, 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 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.
17. 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.
18. Transmission Range Indicator
This display indicator shows the automatic transaxle gear
selection. UNDERSTANDING YOUR INSTRUMENT PANEL 201

NOTE: You must apply the brakes before shifting from
Park.
19. 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.
20. High Beam Light
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. 21. 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
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations the vehicle will drive normally and will
not require towing.
The Malfunction Indicator Light flashes to alert to serious
conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be
serviced as soon as possible if this occurs.202 UNDERSTANDING YOUR INSTRUMENT PANEL

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. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• 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.
• For vehicles equipped with fold-in-floor seating, if it
is necessary to retrieve the spare tire from under the
vehicle on the side of the vehicle close to moving
traffic. Pull far enough off the road to avoid the
danger of being hit.346 WHAT TO DO IN EMERGENCIES

NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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 required maintenance
services determined by the engineers who designed your
vehicle.
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 engine lubrication, 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 379
7

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. Engine Oil Dipstick380 MAINTAINING YOUR VEHICLE
