If the ignition is OFF and any door is left ajar for 10 minutes
or the dimmer control is rotated all the way up to the dome
on position for 10 minutes, the interior lights will automati-
cally turn off.
NOTE:
Battery saver mode is canceled if the ignition 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 automatically turn off.
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 its farthest upward position. If your vehicle is equipped
with remote keyless entry and the unlock button is pushed
on the 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 last (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.
Courtesy Lights
The courtesy lights can be turned on by pushing the top
corner of the lens. To turn the lights off, push the lens a
second time.
