²Turns on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
²Unlocks the doors automatically.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system could cause it to fail when
you need it. You could be injured if the airbag system is not there to
protect you. Do not modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub trim cover or the
upper passenger side of the instrument panel. Do not modify the front
bumper or vehicle body structure.
²Do not attempt to modify any part of your advanced airbag system. The
airbag may inflate accidentally or may not function properly if modifica-
tions are made. Take your vehicle to an authorized dealer for any advanced
airbag system service. If your seat including your trim cover and cushion
needs to be serviced in any way (including removal or loosening/
tightening of seat attachment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accessories may be used. If it is
necessary to modify an advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
²Do not place or hang any items such as add-on video players on the front
passenger seat back. The additional weight may cause the Occupant
Classification 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.
²It 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.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
82 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

6. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will turn on when the key is in the ON position before
engine start. If the light does not turn on when turning
the key from LOCK or ACC to ON, have the condition
checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may turn on the light after engine
start. The vehicle should be serviced if the light stays on
through several of your typical driving cycles. In most
situations, the vehicle will drive normally and it will not
require towing.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalyticconverter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 399 for more
information.)
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
7. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the Multi-Function Control Lever on
the left side of the steering column toward you to switch
to Low beam. (See page 133 for more information.)

NOTE:The factory default zone is 8. During program-
ming, the zone value will wrap around from zone 15 to
zone 1.
Calibrating the Compass (Mid Line Cluster Only)
If the compass appears erratic, inaccurate, or abnormal,
you may wish to calibrate it. However, prior to calibrat-
ing the compass, make sure the proper Compass Variance
value is selected.
NOTE:The vehicle speed must be at 0 mph (0 km/h)
(manual transmission) or the gear selector lever in ªPº
(Park) (auto transmission) to enter the calibration mode.
To calibrate the compass, first, start the engine. Next,
press and hold the trip odometer button until the current
variance zone number displays (approximately ten sec-
onds). Then, press and hold the button again until the
direction displays with the ªCALº indicator on continu-
ously (approximately ten seconds). Finally, drive thevehicle in one or more complete circles, at speeds under
5 mph (8 km/h), in an area free from power lines and
large metallic objects, until the ªCALº indicator turns off.
The compass will now function normally.
ELECTRONIC VEHICLE INFORMATION CENTER
(EVIC) Ð IF EQUIPPED
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display. It is located at the
bottom of the speedometer in the instrument cluster.
Vehicles equipped with steering wheel mounted buttons
(described in this section) are also equipped with the
EVIC. The EVIC consists of the following:
²System Status
²Vehicle information warning message displays
²Tire Pressure Monitor System (If Equipped)
²Personal Settings (Customer Programmable Features)

RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM (Ampli-
tude Modulation), in which the transmitted sound causes
the amplitude, or height, of the radio waves to vary... and
FM (Frequency Modulation), in which the frequency of
the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:For vehicles not equipped with the Electronic
Vehicle Information Center (EVIC), the radio and steering
wheel radio controls (if equipped) will remain active for

45 seconds after the ignition switch is turned to the

NOTE:For vehicles equipped with the EVIC, the radio
and steering wheel radio controls (if equipped) will
remain active for up to 10 minutes after the ignition
switch is turned to the LOCK position. Opening either
front door will cancel this feature. The time is program-
mable. For details, refer to ªDelay Power Off to Accesso-
ries Until Exit,º under ªPersonal Settings (Customer
Programmable Features),º under ªElectronic Vehicle In-
formation Center (EVIC)º in Section 4 of this manual.SALES CODE REQ Ð AM/FM STEREO RADIO
