2014 JEEP GRAND CHEROKEE oil pressure

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. 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,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected, the cause
should be located and corrected immediately.
116 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

12. 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
(Continued)
CAUTION!(Continued)
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized 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 paragraph.4

NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.

•Oil Pressure Warning Light
This telltale indicates low engine oil pressure. 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.
• Oil Temperature Warning Light
This telltale indicates engine oil temperature is
high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as
possible. •
Charging System Light
This light shows the status of the electrical charging
system. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential elec-
trical devices or increase engine speed (if at idle). If the
charging system light remains on, it means that the vehicle
is experiencing a problem with the charging system. Obtain
SERVICE IMMEDIATELY. See an authorized dealer.
If jump starting is required, refer to “Jump Starting Proce-
dures” in “What To Do In Emergencies”.
• Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.

Press and release the UP or DOWN arrow button until
“Tire Pressure” is highlighted in the EVIC.If tire pressure is OK for all tires a vehicle ICON is
displayed with tire pressure values in each corner of the
ICON.
If one or more tires have low pressure, “Inflate Tire To
XX” is displayed with the vehicle ICON and the tire
pressure values in each corner of the ICON with the
pressure value of the low tire displayed in a different
color than the other tire pressure value.
If the Tire Pressure system requires service, “Service Tire
Pressure System” is displayed.

Braking Distance
When selected, this screen displays the vehicle’s braking
distance and the speed at which the brake pedal was
depressed.
•This feature will only function when applying the
brakes at speeds above 30 mph (48 km/h).
• The distance measurement will be aborted if the brake
pedal is released before the vehicle comes to a com-
plete stop.
G-Force
When selected, this screen displays all four G-Force
values (two lateral and two longitudinal) as well as
steering angle. When a force greater than zero is measured, the display
will update the value as it climbs. As the G-Force falls,
the peak forces will continue to display.
Gauges 1
When selected, this screen displays the following values:
•
Oil Temperature
Shows the actual oil temperature within the range of the
gauge.
• Oil Pressure
Shows the actual oil pressure.
• Battery Voltage

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced. Refer
to “Replacement Tires” in this section for further infor-
mation.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of V or
higher, and summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.
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
448 STARTING AND OPERATING
