2007 JEEP PATRIOT check oil

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 lamp 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. Brake fluid level should be checked
when 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. The
Manual 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 manufacturers recommended brake fluid, refer
to Fluids, Lubricants and Genuine Parts for correct fluid
type.

Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more that 3/16º (4.7 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
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 unless the
following conditions exist:
²The lubricant has become contaminated with water. If
contaminated with water, the fluid should be changed
immediately.
²If severe usage has occurred, refer to Maintenance
Schedule ªBº in Section 8 of this manual.
Rear Drive Assembly (RDA )± AWD/4WD Models
Only
Lubricant Selection
Use only manufacturers recommended fluid. Refer to
Fluids, Lubricants and Genuine Parts for correct fluid
type.
Fluid Level Check
Visually inspected the unit at each oil change for leakage.
If leakage is detected, Check the fluid level by removing
the fill plug. The fluid level should be maintained be-
tween the bottom of the fill hole to 1/8 inch (4 mm)
below the fill hole.
Add fluid, if necessary, to maintain the proper level.
Frequency Of Fluid Change
Refer to the ªMaintenance Schedule located if section 8 of
this manual for the correct change interval for your type
of driving.

Appearance Care And Protection From Corrosion
Protection Of Body And Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.

²Off-road or desert operation.
²Heavy Loading
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule ªBº of the
9Maintenance Schedules9section of this manual.
NOTE:IfANYof these apply to you then change your
coolant every 102,000 miles (170 000 km) or 60 months,
whichever comes first and follow schedule ªBº of the
9Maintenance Schedules9section of this manual.
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule9B9.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.NOTE:Under no circumstances should oil change in-
tervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add, if
required.

²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake/
clutch master cylinder, and manual transaxle and add
as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the CV joints (if equipped) and front suspen-
sion components.
²Check the manual transmission fluid level (if
equipped).
²Check the coolant level, hoses, and clamps.
CAUTION!
Do not check the automatic transaxle fluid. It must be
check by a trained service technician every 15,000
miles and if required only the recommended fluid be
added. Refer to the section ªFluids, Lubricants And
Genuine Partsº for the proper fluid.
