Required Maintenance for Noise Control Systems
The following maintenance services must be performed
every 6 months or 6,000 miles (9 600 km), whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed
or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and the cover is tight. Check all hoses leading to the
cleaner for tightness. The gasket between the air cleaner
housing and throttle body must be intact and in good
condition. The engine air cleaner filter must also be clean
and serviced according to the instructions outlined in the
appropriate maintenance schedule.

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle's battery:
²Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
²The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
²As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutesin the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated, the gages in the Instrument Cluster will do
a full sweep, when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:When the vehicle is shipped from the factory,
the IOD fuse is in the up, or extracted position. If the
radio, interior lamps, keyless entry, or other features do
not work with the key off, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the instru-
ment cluster, in the odometer window, will display9NO

sion control devices and systems on your vehicle may be

nia, California Air Resources Board regulations.

The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
The ªChange Oilº message will flash in the instrument
cluster odometer and a single chime will sound, indicat-
ing that an oil change is necessary.
Based on engine operation condition the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 miles (805 km).

SUGGESTIONS FOR OBTAINING SERVICE FOR
YOUR VEHICLE
Prepare For The Appointment
If you're having warranty work done, be sure to have the
right papers with you. Take your warranty folder. All
work to be performed may not be covered by the
warranty, discuss additional charges with the service
manager. Keep a maintenance log of your vehicle's
service history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle's problems or the
specific work you want done. If you've had an accident,
or work done that is not on your maintenance log, let the
service advisor know.
Be Reasonable With Requests
If you list a number of items, and you must have your
vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.
At many dealers, you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is advisable
to make these arrangements when you call for an ap-
pointment.
IF YOU NEED ASSISTANCE
The manufacturer and its dealers are vitally interested in
your satisfaction. We want you to be happy with our
products and services.
Warranty service must be done by an authorized
Chrysler, Dodge, or Jeep dealer. We strongly recommend
that you take your vehicle to your selling dealer. They
know you and your vehicle best, and are most concerned
that you get prompt and high quality service. The
manufacturer's dealers have the facilities, factory-trained
