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 that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently serviced, recently had a dead battery or a battery replace-
ment. If the OBD II 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 II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not
crank or start the engine.
2. If you crank or start the engine, you will have to start
this test over.
3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part of
a normal bulb check.
4. Approximately 15 seconds later, one of two things will
happen:

*Cavities 11, 12, and 13 contain self-resetting fuses
(circuit breakers) that are only serviceable by an autho-
rized dealer. The cluster, the driver seat switch (if
equipped), and the memory module (if equipped) are
fused by the 25 Amp circuit breaker in Cavity 11. The
passenger seat switch (if equipped) is fused by the
25 Amp circuit breaker in Cavity 12. The door modules,
the driver power window switch, and the passenger
power window switch are fused by the 25 Amp circuit
breaker in Cavity 13. If you experience temporary or
permanent loss of these systems, see your authorized
dealer for service.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days, you may want to take these steps to protect your
battery.
•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
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with an oily surface, clean the
bulb with rubbing alcohol.
Low Beam Headlamp, High Beam Headlamp, and
Park/Turn Lamp – 300C
High Intensity Discharge Headlamps (HID) — If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of
this, you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
HID headlamps when the headlamp switch is turned
ON. It may cause serious electrical shock or electro-
cution if not serviced properly. See your authorized
dealer for service.
NOTE: On vehicles equipped with HID headlamps,
when the headlamps are turned on, there is a blue hue to
the lights. This diminishes and becomes more white after
approximately 10 seconds, as the system charges.
