78 GETTING TO KNOW YOUR VEHICLE
Ambient Light — If Equipped
The overhead console is equipped with an ambient light
feature. This light casts illumination for improved visibility
of the floor and center console area.
Ambient Light
Dimmer Control
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 its farthest upward position. If your vehicle is equipped
with a key fob and the unlock button is pushed, 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 (O) 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.
