again. (If the parking lamps are already on, they will
have to be turned off, then back on to disable twilight).

Interior Lamps
Instrument Panel Intensity/Brightness Control
The brightness of the
instrument panel lights can
be adjusted by moving the
INTERIOR lever between
LO and HI.
The instrument panel lights will be on only when the
parking lamps are on. The interior courtesy lamps can
be turned on by sliding the INTERIOR lever all the
way to the top, to HI.
Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps on
by sliding the INTERIOR lever all the way to the top.
Illuminated Entry
If it is dark enough outside when you press the button
with the unlock symbol on the remote keyless entry
transmitter, the interior courtesy lamps will turn on and
stay on for approximately 40 seconds. The lamps will
turn off immediately by pressing the button with the
lock symbol on the remote keyless entry transmitter,
turning the ignition key to RUN or activating the power
door locks.
Delayed Entry Lighting
If it is dark enough outside when you open the door,
the interior lamps will turn on. When you close the door
with the ignition off, the interior lamps will stay on for
up to 25 seconds or until the ignition is turned to an
on position. When the lamps turn off as a result of the
25 second timer or the ignition switch being turned on,
the lighting will deactivate via the theater dimming
effect. Locking the doors will override the delayed entry
lighting feature and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out
of the courtesy lamps instead of immediate turn off.

Instrument Panel Clusters
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how
fast you're going, how much fuel you're using, and many other things you'll need to drive safely and economically.
Your vehicle is equipped with one of these instrument panel clusters, which includes indicator warning lights and
gages that are explained on the following pages.
Standard Cluster (United States version shown, Canada similar)

2-72 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see
ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so
it will be ready to warn you if there is a problem.

Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on
-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Light
If your vehicle has the
standard instrument panel
cluster, this light will come
on if there is a problem
with your vehicle's engine
oil pressure.
If your vehicle has the optional gage cluster, you
can read your oil pressure directly from the Driver
Information Center (DIC). See ªDIC Displays and
Controlsº in the Index.
The oil pressure light will come on briefly when you
turn your key to RUN. That's just a check to be sure
the light works. This is normal and doesn't show a
problem. If it doesn't come on and then go off,
be sure to have it fixed so it will be there to warn
you if there is a problem.
