2015 JEEP RENEGADE oil pressure

after a fully warmed engine is shut off. Do not check oil
level before starting the engine after it has sat overnight.
Checking engine oil level when the engine is cold will
give you an incorrect reading.
Checking the oil while the vehicle is on level ground, and
approximately five minutes after a fully warmed engine
is shut off, will improve the accuracy of the oil level
readings. Maintain the oil level between the range mark-
ings on the dipstick. The safe range is indicated by a
crosshatch zone. Adding 1 quart (0.9 Liters) of oil when
the reading is at the low end of the indicated range will
result in the oil level at the full end of the indicator range.
CAUTION!
Do not overfill the engine with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil

temperature. This loss of oil pressure and increased
oil temperature could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE: Under no circumstances should oil change in-
tervals exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first.

cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•Use 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
Warranty Information Book, located on the DVD,
for further warranty information.
•The 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 technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.

worn to the tread wear indicators, the tire should be
replaced. Refer to “Replacement Tires” in this section for
further information.
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
