2015 JEEP CHEROKEE low oil pressure

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16” (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 - Improper cold tire inflation pressures
can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replace-
ment.
•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
562 STARTING AND OPERATING

NOTE:There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
•You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a
supplement to the radiator and aids in removing heat
from the engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

616 WHAT TO DO IN EMERGENCIES

(D) Drive Vehicle:
Immediately after injecting sealant and inflating the tire,
drive the vehicle 5 miles (8 km) or 10 minutes to ensure
distribution of the Tire Service Kit Sealant within the tire.
Do not exceed 55 mph (90 km/h).
WARNING!
Tire Service Kit is not a permanent flat tire repair.
Have the tire inspected and repaired or replaced after
using Tire Service Kit. Do not exceed 55 mph (90
km/h) until the tire is repaired or replaced. Failure to
follow this warning can result in injuries that are
serious or fatal to you, your passengers, and others
around you.
(E) After Driving:
Pull over to a safe location. Refer to “Whenever You Stop
to Use Tire Service Kit” before continuing.
1. Push in the Mode Select Knob (5) and turn to the Air
Mode position.
2. Uncoil the power plug and insert the plug into the
vehicle’s 12 Volt power outlet.
3. Uncoil the Air Pump Hose (7) (black in color) and
screw the fitting at the end of hose (7) onto the valve
stem.
4. Check the pressure in the tire by reading the Pressure
Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar):
The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance.
626 WHAT TO DO IN EMERGENCIES

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 or air conditioning. Such damage is
not covered by the New Vehicle Limited Warranty.
If a flush is needed because of component malfunc-
tion, use only the specified fluid for the flushing
procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, 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 1 quart (0.9 L) 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.

MAINTAINING YOUR VEHICLE 661

•Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
•Check the fluid levels of the coolant reservoir and
brake master cylinder, fill 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 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
