Section 3 Instrument Panel

The exterior lamp control has three positions:
9(Off):Turning the control to this position turns off
all lamps except the Daytime Running Lamps (DRL).
;(Parking Lamps):Turning the control to this
position turns on the parking lamps, together with the
following:
·Sidemarker Lamps
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
·Ashtray Lamp
O(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also dim.
Your vehicle is equipped with a light sensor on the top of
the instrument panel in the defroster grille. Be sure it
is not covered, or the system will be on whenever
the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
3-13

When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the last
chosen headlamp setting that was used.
To idle your vehicle with the DRL off, put the
transmission in PARK (P). The DRL will stay off until
you shift out of PARK (P).
The following does not apply to vehicles ®rst sold in
Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following the steps below:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that
the system is off.
To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds (the
chime will sound), or turn the ignition to off and then to
RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Interior Lamps
Instrument Panel Brightness Control
The thumbwheel for this feature is located to the right of
the exterior lamps control.
(Instrument Panel Brightness):Turn the thumbwheel
up to brighten the lights or down to dim them.
Moving the thumbwheel up to the ®rst position will
activate the interior dome lamps.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lights will not
come on if the DOME OVERRIDE button is pressed in.
Entry Lighting
Your vehicle is equipped with an illuminated entry
feature.
When a door is opened, the dome lamps will come on if
the DOME OVERRIDE button is in the out position.
When all the doors are closed, the lamps will stay on for
a short period of time and will then go out. If the
DOME OVERRIDE button is pressed in, the lamps will
not come on.
