Transmitter Battery Service
The recommended replacement battery is the Panasonic
CR2032 or equivalent.
1. Pry the transmitter halves apart with a dime or similar
object. Make sure not to damage the rubber gasket
material during removal.2. Remove and replace the batteries. Avoid touching the
new batteries with your fingers. Skin oils may cause
battery deterioration. If you touch the battery, clean it
with rubbing alcohol.
3. Reassemble the transmitter case. Snap the halves
together and test transmitter operation.
DOOR LOCKS
The vacuum fluorescent (VF) display located in the
odometer area displays the word “door” as an indication
of a door ajar or door not completely closed. When the
vehicle is not moving and the door is ajar or not
completely closed, the VF display will show the word
“door” and then show the odometer/trip odometer
mileage (each for 2 seconds). The display will continue to
cycle.

the fuel filler cap properly to turn the message off (light

appear the next time the vehicle is started.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a batteryreplacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
318 MAINTAINING YOUR VEHICLE

a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the
ignition key or start the engine. This means that your
vehicle’s OBD system isnot readyand you shouldnot
proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle’s OBD system
isreadyand you can proceed to the I/M station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the MIL symbol is illuminatedduring normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Moparparts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
DEALER SERVICE
Your dealer has the qualified service personnel, special
tools, and equipment to perform all service operations in
an expert manner. Service Manuals are available which
include detailed service information for your vehicle.
Refer to these manuals before attempting any procedure
yourself.

Underhood Fuses (Power Distribution Center)
Your vehicle is equipped with an electrical power distri-
bution center located in the engine compartment near the
battery. This power center houses plug-in “Cartridge”
fuses which replace in-line fusible links. The power
center also contains “Mini” fuses and plug-in full and
micro ISO relays. A label inside the latching cover of the
center identifies each component for ease of replacement,
if necessary. “Cartridge” fuses and relays can be obtained
from your authorized dealer.
Power Distribution Center

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
•Store the removed IOD fuse in the Power Distribution
Center location #11 labeled “IOD Storage.”
•Or, disconnect the negative cable from the battery.
•Anytime 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 minutes
in 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.
