low oil pressure JEEP WRANGLER 2013 JK / 3.G Owners Manual

7. Seat Belt Reminder LightWhen the ignition switch is first turned to ON/
RUN, this light will turn on for four 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 bulb check or when driving, if the driver seat
belt remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
8. Turn Signal Indicators
The left or right arrow will flash with the corre-
sponding exterior turn signal lights when the turn
signal lever is operated. A chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn signal on.
NOTE: If either indicator flashes at a rapid rate, check
for a defective outside light bulb. 9. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine is
started; if the bulb does not come on, have the system
checked by an authorized dealer. If the light turns on
while driving, stop the vehicle and shut off the engine as
soon as possible. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
10. High Beam Indicator
This indicator shows that the high beam head-
lights are on. Push the multifunction control lever
away from you to switch the headlights to high beam.

17. Vehicle Security Light — If EquippedThis light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
18. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the 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 imme-
diately and call an authorized dealer 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 an authorized dealer for service if your
vehicle overheats. If you decide to look under the hood
yourself, see “Maintaining Your Vehicle”. Follow the
warnings under the Cooling System Pressure Cap para-
graph.

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 a collision 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 or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the Tire Safety Information section of this
manual for more information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire or
original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.

STARTING AND OPERATING 497

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been 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 1 U.S. Quart (0.95L) 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.
574 MAINTAINING YOUR VEHICLE

NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following
page for the required maintenance intervals.At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter
• Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required
• Inspect automatic transmission fluid if equipped
with dipstick
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake
•
Inspect engine cooling system protection and hoses
• Inspect exhaust system
• Inspect engine air cleaner if using in dusty or
off-road conditions
• Inspect all door latches for presence of grease,
reapply if necessary.
