2010 JEEP LIBERTY Owners Manual

When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points to Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant bottle.
•Check coolant freeze point in the radiator and in the
coolant recovery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant recovery bottle
must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
440 MAINTAINING YOUR VEHICLE

•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance, poor gas
mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
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 would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
“Brake Warning Light” is illuminated.
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 brake
fluid reservoir. With disc brakes, 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 “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its per-
formance. The proper type of brake fluid for your
vehicle is also labeled on the original factory
installed hydraulic master cylinder reservoir.(Continued)
WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.(Continued)
442 MAINTAINING YOUR VEHICLE

WARNING! (Continued)
•Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in an accident.
Automatic Transmission
Fluid Level Check
Your vehicle is equipped with a capped transmission oil
fill tube that is sealed and it should not be tampered with.
Your authorized dealer has the proper tools to ensure that
the fluid level is set properly.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than that
recommended by the manufacturer will result in
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for the correct fluid type.
Fluid and Filter Changes
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
In addition, change the fluid and filter if the transmission
is disassembled for any reason.

Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. The only
exception to this policy is the use of special dyes to aid in
detecting fluid leaks. The use of transmission sealers
should be avoided as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Transfer Case
Fluid Level Check
The fluid level should be to the bottom edge of the fill
hole (1) when the vehicle is in a level position.
Adding Fluid
Fluid should be added only to fill hole until fluid begins
to run out of the hole.
1 — Fill Plug
2 — Drain Plug
444 MAINTAINING YOUR VEHICLE

Draining Fluid
First remove the fill plug (1), then the drain plug (2).
Recommended tightening torque for the drain and fill
plugs is 15–25 ft lbs (20–34 N·m).
CAUTION!
Do not over-tighten the plugs. You could damage
them and cause a leak.
Lubricant Selection
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.
Frequency of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life ofthe vehicle. Fluid changes are not necessary unless the
fluid becomes contaminated with water. Change the fluid
immediately if contaminated with water.
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 “Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.7
MAINTAINING YOUR VEHICLE 445

Frequency of Fluid Change
Under normal operating conditions, the lubricant in-
stalled at the factory will give satisfactory lubrication for
the 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.
Sky Slider™Top Care
Immediate removal of any contaminant is recommended.
Regular washing of the top will enhance its life and
appearance, and make successive cleaning easier. Do not
subject the top to excessive heat. Frequently vacuum the
top and tracks. Periodically wipe dust and dirt from the
top and inside of the tracks by hand with an alcohol
dampened cloth.
Washing
Hand washing or an automatic car wash with a soft cloth
system is preferred.
CAUTION!
Avoid pointing a high-pressure hand held spray
wand directly at the sides of the top, as this can
damage the seal and force water past the weather
strips.
General Cleaning
Careful vacuuming of the top before washing is helpful
in removing dust and other foreign particles.
If hand washing:
•Wash in partial shade instead of direct sun.
•Wet the entire vehicle before washing the top.
•Wash the top with a soft, natural bristle scrub brush,
and a mild soap solution such as liquid dish washing
soap. Do not use detergent.
446 MAINTAINING YOUR VEHICLE

•Scrub in all directions, covering an area of about two
square feet at a time. Avoid heavy scrubbing.
•Rinse the entire vehicle with water to remove all soap
and dirt from the top fabric and to prevent streaking
on painted and chrome surfaces.
•Allow the top to dry before opening. Vacuuming the
top with a wet/dry shop vacuum will decrease the
tops drying time, ensure removal of all dirt, and delete
streaks in the material.
•Multiple cleanings may be necessary to remove stub-
born stains. If stains persist, contact your local autho-
rized dealership for further suggestions.
CAUTION!
Never use an abrasive type cleaner or bleaches.
Cleaners should not contain silicones, organic sol-
vents, petroleum distillates, or plasticizers. Always
wait until the top is thoroughly dry before opening
it.
Additional Cleaning Procedure
For additional cleaning assistance in removing stubborn
stains, apply MOPARConvertible Cloth Top Cleaner or
equivalent to the complete stain, extending 2 in (50 mm)
beyond the stain. With a soft bristle brush, scrub in all
directions over the stain. Avoid heavy scrubbing. Rinse
the area with warm water. If the stain is still apparent,
repeat the cleaning procedure. When the stain is no
longer showing, rinse the complete top with warm water.
Let the top dry before opening it.
