Interior Lights
Courtesy and dome lights are turned on when
the front doors are opened or when the dimmer
control (rotating wheel on the right side of the
headlight switch) is rotated to the its farthest
upward position. If your vehicle is equipped with
Remote Keyless Entry (RKE) and the UNLOCK
button is pushed on the RKE key fob, the
courtesy and dome lights will turn on. When a
door is open and the interior lights are on,
rotating the dimmer 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 vehicle's battery.
The brightness of the instrument panel lighting
can be regulated by rotating the dimmer control
up (brighter) or down (dimmer). When the head-
lights are on you can supplement the brightness
of the DID, 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.

minutes, the interior lights will automatically turn

Battery saver mode is cancelled if the igni-
tion is ON.
If the headlights remain on while the ignition is
cycled OFF, the exterior lights will automatically
turn off after eight minutes. If the headlights are
turned on and left on for eight minutes while the
ignition is OFF, the exterior lights will automati-
cally turn off.
