Instrument Panel Brightness Control
This button controls the
brightness of your
instrument panel lights
when your headlamps or
parking lamps
are on.
Ish and release the button and it will pop out. Turn the
button clockwise (to the right) to brighten the lights or
counterclockwise (to the left) to dim them.
The instrument panel brightness knob has an added
feature called Parade Mode to assist you in seeing
certain instrument panel controls if your headlamps
are
on in the daylight. Right before turning the courtesy
lamps on by turning the button all the way to the right,
the radio, Driver Information Center (DIC) display and
heating and air conditioning controls will come on at
their maximum brightness. This will occur only with the
parking lamps or headlamps on.
Courtesy Lamps
When any door or the hatch/trunk lid is opened, the
interior lamps will go
on (unless it’s bright outside). The
lamps will stay on for about
30 seconds or until you turn
on the ignition.
You can
also turn on the courtesy lamps by turning the
interior brightness control button all the way to the right.
Be sure not to have this knob turned all the way down
with the lamps on during the day. Your Driver
Information Center
(DIC) may not be visible.

CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions
are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
