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 maynotbe ready if your vehicle was recentlyserviced, 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. 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 the MIL symbol come on as part of a normal bulb
check.

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.

contamination will severely shorten bulb life. If the
bulb comes in contact with an oily surface, clean the
bulb with rubbing alcohol.
Low Beam Headlight, High Beam Headlight, and
Park/Turn Light – 300C
High Intensity Discharge Headlights (HID) — If
Equipped
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
HID headlights when the headlight 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 Headlights,
when the headlights 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.
