check engine JEEP LIBERTY 2009 KK / 2.G Owner's Manual

the engine operating temperature is satisfactory, the
coolant bottle need only be checked once a month.
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.
428 MAINTAINING YOUR VEHICLE

WARNING!
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
•Use 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 specification
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.
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.
430 MAINTAINING YOUR VEHICLE

NOTE:
•The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been six months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
•Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
•Under no circumstances should oil change intervals
exceed 6,000 miles (10 000 km) or six months, which-
ever comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under “Oil Change Required” in “Use Factory Settings” of the EVIC section in this manual or under
“Odometer/Trip Odometer” in the “Instrument Cluster
Descriptions section of this manual.
At Each Stop for Fuel
•Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.

•Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and add as needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
