2009 DODGE NITRO oil pressure

Seat belt assemblies must be replaced after an accident if
they have been damaged i.e., (bent retractor, torn web-
bing, etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Airbag Warning Light
The light should come on, and remain on for six to eight
seconds as a bulb check, when the ignition switch is first
turned ON. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defrosters
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. See
your authorized dealer for service if your defroster is
inoperable.
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 for tread cuts or sidewall
cracks. Check wheel nuts for tightness. Check the tires
(including spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check the area under the vehicle after overnight parking
for fuel, coolant, oil or other fluid leaks. Also, if gasoline
fumes are detected, the cause should be located and
corrected immediately.
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 an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see Section 7
of this manual. Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
4. Low Fuel Light
When the fuel level reaches approximately 2.0 gal
(7.8 L) this light will turn on, and remain on until
fuel is added.
5. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulbcheck or when driving, if the driver’s seat belt remains
unbuckled, the Seat Belt Reminder Light will illuminate
and the chime will sound. Refer to “Occupant Restraints”
in Section 2 for more information.
6. Engine Temperature Warning Light
This light warns of an overheated engine condition.
As temperatures rise and the gauge approachesH
,
this indicator will illuminate and a single chime
will sound after reaching a set threshold. Further over-
heating will cause the temperature gauge to passH, the
indicator will continuously flash and a continuous chime
will occur until the engine is allowed to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.

21. Oil Pressure Warning Light
This light indicates 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 four 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.
22. Airbag Warning Light
This light turns on and remains on for seven
seconds as a bulb check, when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible.23. Tachometer
This gauge measures engine revolutions-per-minute
(RPM x 1000).
24. Shift Lever Indicator
The electronic shift lever 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. The display will place
a box around the selected transmission range (PRND21).
If the PRNDL displays only the characters PRND21 (no
boxes) have the system checked by an authorized dealer.

•Oil change required (with a single chime).
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style. Unless reset, this message
will continue to display each time you turn the ignition
switch to the ON/RUN position. To turn off the message
temporarily, press and release the MENU button. To reset
the oil change indicator system (after performing the
scheduled maintenance) refer to the following procedure.

WARNING!
Tires and the 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
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your
tires. 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.

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 Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
