maintenance JEEP LIBERTY 2009 Owners Manual

WARNING! (Continued)
•Do not place or hang any items such as add-on
video players on the front passenger seatback. The
additional weight may cause the Occupant Classi-
fication System to be unable to classify the front
seat passenger correctly. This could allow the
passenger frontal airbag to inflate when it is not
desired.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•The Airbag Warning Light does not come on or flickers
during the six to eight seconds when the ignition
switch is first turned ON.
•The light remains on or flickers after the six to eight
second interval.
•The light flickers or comes on and remains on while
driving.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws, contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in “Engine Oil”, under “Maintenance Procedures”
in section 7 of this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Engine Oil Filter Selection
All of this manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high-quality filters should be used to assure
most efficient service. MOPARengine oil filters are
high-quality oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
NOTE: Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.

CAUTION! (Continued)
•If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage
as battery damage can result.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
