2008 JEEP LIBERTY check oil

Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Make sure that they are not frozen to the
glass before turning them on to avoid damaging the
blade.
Keep the blade rubber out of contact with petroleum
products such as engine oil, gasoline, etc.
NOTE:Always refer to the wiper blade packaging for
specific installation instructions. Many wiper blade re-
placements fit multiple vehicles.Windshield & Rear Window Washers
The windshield and rear window washers share the same
fluid reservoir. The fluid reservoir is located in the front
of the engine compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill the reservoir
with windshield washer solvent (not radiator antifreeze)
and operate the system for a few seconds to flush out the
residual water.
When refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and wipe
clean the wiper blades, this will help blade performance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.

²Inspect the brake hoses whenever the brake system is
serviced and at every engine oil change. Inspect hy-
draulic brake hoses for surface cracking, scuffing, or
worn spots. If there is any evidence of cracking,
scuffing, or worn spots, the hose should be replaced
immediately! Eventual deterioration of the hose can
take place resulting in a possibility of a burst failure.
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.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.Check the fluid level in the master cylinder when per-
forming underhood services.
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 brake fluid reser-
voir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
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.
Use only manufacturer's recommended brake fluid. Re-
fer to ªFluids, Lubricants, and Genuine Partsº in this
section for the correct fluid type.

NOTE:Be sure to follow the ªpolice, taxi, fleet, off-road,
or frequent trailer towingº maintenance interval if appli-
cable.
Front/Rear Axle Fluid
Fluid Level Check
The lubricant level should be at bottom edge of the oil fill
hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Lubricant Selection
Use only manufacturer's recommended lubricant. Refer
to ªFluids, Lubricants, and Genuine Partsº in this section
for the correct fluid type.
Frequency of Fluid Change
Under normal operating conditions, the lubricant in-
stalled at the factory will give satisfactory lubrication forthe life of the vehicle. Lubricant changes are not neces-
sary unless the lubricant becomes contaminated with
water. Change the lubricant immediately if contaminated
with water.
NOTE:Be sure to follow the ªpolice, taxi, fleet, off-road,
or frequent trailer towingº maintenance interval if appli-
cable.
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
428 MAINTAINING YOUR VEHICLE

NOTE:
²The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been 6 months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If a scheduled
oil change is performed by someone other than your
dealer, the message can be reset by referring to the steps
described under ªOil Change Requiredº under ªElec-
tronic Vehicle Information Center (EVIC)º in Section 3 ofthis manual or under ªOdometer/Trip Odometerº under
ªInstrument Cluster Descriptionsº in Section 3 of this
manual.
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.
