initiated when the ignition is turned OFF while
the headlight switch is on, and then the head-
light switch is cycled off. Headlight delay can
be cancelled by either turning the headlight
switch on then off, or by turning the ignition ON.
The headlight delay time is programmable on
vehicles equipped with an Electronic Vehicle
Information Center (EVIC). Refer to “Electronic
Vehicle Information Center (EVIC)/Customer-
Programmable Features” in “Understanding
Your Instrument Panel” for further information.
Parking Lights and Panel Lights
To turn on the parking lights and instru-
ment panel lights, rotate the headlight
switch clockwise. To turn off the park-
ing lights, rotate the headlight switch back to
the O (Off) position.
Front And Rear Fog Lights — If
Equipped
The front and rear fog lights may be operated
as desired when visibility is poor due to fog.
The fog lights will activate in the following order:
Press the headlight switch once and the front
fog lights come on. Press the switch a second time and the rear fog lights will come on (front
fog lights stay on). Press the switch a third time
and the rear fog lights turn off (front fog stays
on). Press the switch a fourth times and the
front fog turns off. For vehicles without front fog,
rear fog will activate on the first press.
NOTE:
The headlight switch must first be turned to
the position lights or headlights position
before the fog lamp switch can be pushed in.
Interior LightsCourtesy and dome lights are turned on when
the front doors are opened, when the dimmer
control (rotating wheel on the right side of the
headlight switch) is rotated to the its farthest
upward position, or if equipped, when the UN-
LOCK button is pressed on the Remote Keyless
Entry (RKE) transmitter. When a door is open
and the interior lights are on, rotating the dim-
mer control all the way down, to the OFF detent,
will cause all the interior lights to go out. This is
also known as the “Party” mode because it
allows the doors to stay open for extended
periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting
can be regulated by rotating the dimmer con-
trol up (brighter) or down (dimmer). When the
headlights are on you can supplement the
brightness of the odometer, trip odometer, radio
and overhead console by rotating the control to
its farthest position up until you hear a click.
This feature is termed the “Parade” mode and
is useful when headlights are required during
the day.

whenever the hood is raised. It can start
anytime the ignition switch is on. You can
be injured by moving fan blades.
• Remove any metal jewelry such as watch
bands or bracelets that might make an
inadvertent electrical contact. You could be
