2004 DODGE DURANGO engine oil

Battery Replacement
The recommended replacement battery is CR2032.
1. If the key fob is equipped with a screw, remove the
screw. With the transmitter buttons facing down, use a
flat blade to pry the two halves of the transmitter apart.
Make sure not to damage the elastomer seal during
removal.2. Remove and replace the batteries. Avoid touching the
new batteries with your fingers. Skin oils may cause
battery deterioration. If you touch a battery, clean it with
rubbing alcohol.
3. To assemble the transmitter case, snap the two halves
together.
NOTE:If the key fob is equipped with a screw, reinstall
and tighten the screw until snug.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors, liftgate, and
ignition for unauthorized operation. When the alarm is
activated, the system provides both audible and visual
signals. The horn will sound repeatedly for 3 minutes
and the headlights and security light in the instrument
cluster will flash for an additional 15 minutes. The engine
will not run until the system is disarmed.
24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 miles (100 km), speeds
up to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits
of local traffic laws, contributes to a good break-in.
Avoid wide open throttle acceleration in low gear.
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.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and is not an indication of difficulty.
SAFETY TIPS
Exhaust System
WARNING!
Exhaust gases contain carbon monoxide, an ex-
tremely toxic gas that by itself is colorless and
odorless. To avoid inhaling these gases, the follow-
ing precautions should be observed:
²Do 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.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²It may be necessary to sit in a parked vehicle with the
engine running for more than a short period. If so,
adjust your climate control system to force outside air
into the vehicle. Set the blower at high speed and the
controls in any position except OFF or RECIRC.
²The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.
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.
Seat 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.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You can feel the air
directed against the windshield.

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
safely pull over and stop the vehicle. Idle the vehicle
in neutral with the air conditioner turned off until
the light turns off. If the if the light remains on, 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.
9. Speedometer
Shows vehicle speed in miles per hour and kilometers
per hour.
10. Voltage Light
This light monitors the electrical system voltage.
The light should turn on momentarily as the
148 INSTRUMENT PANEL AND CONTROLS

engine is started. If the light stays on or turns on while
driving, it indicates a problem with the charging system.
Immediate service should be obtained.
11. Liftgate Open
The Gate Open light will illuminate when the liftgate is
not properly closed and the ignition is ON.
12. Security Light
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.
13. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual.
This light will come on when the ignition key is
turned to the ON position and may stay on for
approximately 3 seconds. If this light remains on orcomes on during driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that
service is required. See your authorized dealer immedi-
ately.
14. Engine Oil Pressure Indicator Light
This light indicates that the engine oil pressure has
become too low. For a bulb check, this light will
come on momentarily when the ignition is turned On. If
the light turns on while driving, stop the vehicle and shut
off the engine as soon as possible. Immediate service
should be obtained.
15. Tachometer
This gage measures engine revolutions-per-minute (rpm
x 1000).
16. Gear Selector
The electronic gear selector display is self-contained
within the instrument cluster. It displays the position of
the automatic transmission shift lever, and the relation of

and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended.When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and press the accelerator slightly for
fast idle operation.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

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 therequiredmaintenance
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 Engine Oil Level
To assure proper lubrication of your vehicle's engine, the
engine oil must be maintained at the correct level. The
best time to check the engine 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.
