2008 JEEP LIBERTY brake

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.

WARNING!
²Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
²Use of a brake fluid that has a lower initial boiling
point than the recommended product or a brake
fluid that is unidentified as to FMVSS specifica-
tion may result in sudden brake failure during
hard prolonged braking. You could have an
accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.
Clutch Hydraulic System Ð Manual Transmission
(If Equipped)
The clutch hydraulic system is fed by a segregated
volume of fluid within the brake system master cylinder
reservoir. In the event of leakage or wear, use only
manufacturer's recommended brake fluid. Refer to ªFlu-
ids, Lubricants, and Genuine Partsº in this section for the
correct fluid type.

Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil and/or excessive brake dust, use Mopart
Wheel Cleaner (05066247AB) or equivalent or select a
nonabrasive, non-acidic cleaner. Do not use scouring
pads, steel wool, a bristle brush, or metal polishes. Only
Mopartor equivalent is recommended. Do not use oven
cleaner. Avoid automatic car washes that use acidic
solutions or harsh brushes that may damage the wheels'
protective finish.
Interior Care
Instrument Panel Cover
The instrument panel cover has a low glare surface,
which minimizes reflections in the windshield. Do notuse protectants or other products, which may cause
undesirable reflections. Use soap and warm water to
restore the low glare surface.
Cleaning Interior Trim
Clean interior trim with a damp cloth and Mopar Total
Clean, and if necessary, follow with Mopar Spot & Stain
Remover. Do not use harsh cleaners or Armorall. Use
Mopar Total Clean to clean vinyl upholstery.
Cleaning Leather Upholstery
MopartTotal Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MopartTotal Clean. Care should be taken to avoid
soaking leather upholstery with any liquid. Please do not

²When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in an electrical system
failure.
²When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
