2008 DODGE DURANGO oil pressure

Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for 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 for proper pressure.
Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 77

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.
8. Speedometer
Shows the vehicles speed.
9. Voltage Light
This light monitors the electrical system voltage.
The light should turn on momentarily as the
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.10. 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.
11. 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 or
comes 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. With the ABS malfunctioning, the BAS and ESP are
also switched off. Both malfunction indicator lights illu-
minate with the engine running. If the charging voltage
falls below 10 volts, the malfunction indicator light

illuminates and the ABS is switched off. When the
voltage is above this value again, the malfunction indi-
cator light should go out and the ABS is operational. If
the malfunction indicator light stays illuminated, have
the system checked at your authorized dealer as soon as
possible.
12. 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.
13. Tachometer
This gauge measures engine revolutions-per-minute
(rpm x 1000).14. 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
each position to all other positions. For a good signal the
display will place a box around the selected transmission
range (PRND21). If the PRNDL displays only the char-
acters PRND21 (no boxes) have the system checked by an
authorized dealer.
15. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed
during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.

WARNING!
Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.
320 STARTING AND OPERATING

WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. Lightly tighten the nuts. To
avoid risk of forcing the vehicle off the jack, do not fully
tighten the nuts until the vehicle has been lowered.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
6. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 135   10 ft.
lbs. (183   14 N´m) dynamic torque. If in doubt about the
correct tightness, have them checked with a torque
wrench by your dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack, tools and the extra tire and wheel
in the places provided.
7. Remove wheel blocks. Do not install chrome or alu-
minum wheel center caps on the spare wheel. This may
result in cap damage.
8. Lower the jack to its fully closed position. Stow the
replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
Change Engine Oil
Follow the Maintenance Schedule for recommended en-
gine oil and filter change intervals.
NOTE:Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
4x4 Models, If Used Primarily For Off-Road Operation
Every 50 hours of use.
Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner and the crankcase inlet air cleaner. The
crankcase ventilation system should also be checked
periodically. Make sure that these units are always clean.
This will tend to reduce to a minimum the amount of
abrasive material that may enter the engine.
392 MAINTAINING YOUR VEHICLE

WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
²The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced repairman.NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oils and Refrigerants.
Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
Front Suspension Ball Joints
The ball joints and seals should be inspected whenever
the vehicle is serviced for other reasons. Damaged seals
should be replaced to prevent leakage or contamination
of the grease.
