2008 JEEP PATRIOT oil change

Windshield Wiper Blade Replacement
1. Lift the wiper arm away from the glass.
2. Push the release tab and slide the wiper blade assem-
bly down along the arm. Gently place the wiper arm on
the windshield.
3. Install the new blade assembly onto the wiper arm tip
until it locks in place.
Windshield Washer Fluid Reservoir
The windshield washer fluid reservoir is located in the rear
of the engine compartment on the right side and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent (not radiator antifreeze).
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.If you notice a change in the sound of the exhaust system,
or if exhaust fumes can be detected inside the vehicle or
when the underside or rear of the vehicle is damaged,
have a competent technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for an oil
change or lubrication. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Exhaust Gas” in the Safety Tips section of this
manual.
364 MAINTAINING YOUR VEHICLE

NOTE:Inspection of brake hoses should be done when-
ever the brake system is serviced and at every engine oil
change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brakefluid reservoir. Fluid level can be expected to fall as the
brake pads wear. The brake fluid level should be checked
when the pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
NOTE:If your vehicle is equipped with amanual
transaxle, the brake fluid reservoir supplies fluid to both
the brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. Themanual
transaxleclutch release system should not require fluid
replacement during the life of the vehicle. If the brake
fluid reservoir is low and the brake system does not
indicate any leaks or other problems, it may be a result of
a leak in the hydraulic clutch release system. See your
local authorized dealer for service.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” under
Section 8.
372 MAINTAINING YOUR VEHICLE

Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary lubricant has
become contaminated with water.
NOTE:If contaminated with water, the fluid should be
changed immediately.
Rear Drive Assembly (RDA) – AWD/4WD Models
Only
Lubricant Selection
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants and Genuine Parts” under Section
8.
Fluid Level Check
Visually inspect the unit at each oil change for leakage. If
leakage is detected, check the fluid level by removing thefill plug. The fluid level should be maintained between
the bottom of the fill hole to 1/8 in (4 mm) below the fill
hole.
Add fluid, if necessary, to maintain the proper level.
Frequency Of Fluid Change
Refer to the “Maintenance Schedule” under Section 8.
Power Transfer Unit (PTU) – AWD/4WD Models
Only
Lubricant Selection
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” under Section
8.
Fluid Level Check
Visually inspected the unit at each oil change for leakage.
If leakage is detected, Check the fluid level by removing

EMISSIONS CONTROL SYSTEM MAINTENANCE
The Scheduled Maintenance services listed inbold type,
must be done at the times or mileages specified to ensure
the continued proper functioning of the Emissions Con-
trol System. These, and all other maintenance services
included in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving.
Inspection and service should also be done anytime a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been
certified pursuant to U.S. EPA or in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULE
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Based on engine operation condition, the oil change
indicator message will illuminate; this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 mi (805 km).

NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been six months since your last oil change and
even if the oil change indicator message is NOT
illuminated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 mi (10 000 km) or six months, whichever
comes first.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If this
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Oil Change
Required” in “Use Factory Settings” of the EVIC section
in this manual or under “Odometer/Trip Odometer” in
the Instrument Cluster Descriptions section of this
manual.
At Each Stop for Fuel
•Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
