brake fluid JEEP LIBERTY 2008 KK / 2.G Owners Manual

Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
82 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE:If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
28. Cruise Indicator Light Ð If Equipped
This indicator lights when the electronic speed
control system is turned on. (See page 147 for
more information.)
29. Transmission Range Indicator
This display indicator shows automatic transmission
gear selection. (See page 281 for more information.)
30. Seat Belt Reminder Light
This light will turn on for several seconds after the
ignition is turned ON as a reminder to ªbuckleup.º This light will remain on as long as the seat belt
remains unbuckled. (See page 48 for more information.)
31. Brake System Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the light turns on, it may indi-
cate that the parking brake is applied, that the
brake fluid level is low, or that there is a problem with the
anti-lock brake system (if equipped).
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. Failure of either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
202 INSTRUMENT PANEL AND CONTROLS

NOTE:The light may flash momentarily during sharp
cornering maneuvers, which can change fluid level con-
ditions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
Vehicles equipped with Anti-Lock brakes (ABS), are also
equipped with Electronic Brake Force Distribution (EBD).In the event of an EBD failure, the Brake Warning Light
will turn on along with the ABS Light. Immediate repair
to the ABS system is required.
The operation of the Brake Warning Light can be checked
by turning the ignition switch from the LOCK or ACC
position to the ON position. The light should turn on for
approximately two seconds. The light should then turn
off unless the parking brake is applied or a brake fault is
detected. If the light does not turn on, have the light
inspected by an authorized dealer. (See page 310 for more
information.)
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.

WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
²Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
²Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
²Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
²Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
²When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
²Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
²During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
²Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
290 STARTING AND OPERATING

NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes ABS (Anti-Lock Brake System), TCS
(Traction Control System), BAS (Brake Assist System),
HSA (Hill Start Assist), ERM (Electronic Roll Mitigation),
and ESP (Electronic Stability Program). These systems
work together to enhance both vehicle stability and
control in various driving conditions.
314 STARTING AND OPERATING

Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the frontor rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control. Also overloading can shorten the life of
your vehicle.

396 MAINTAINING YOUR VEHICLE

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the ªMainte-
nance Scheduleº in Section 8 of this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:
²Often, fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations
to ease the assembly of hoses to couplings. Therefore,
oil wetness at the hose-coupling area is not necessarily
an indication of leakage. Actual dripping of hot fluid
when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.
422 MAINTAINING YOUR VEHICLE

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.
