Twilight Sentinel

To operate the Twilight Sentinel, leave the exterior lamp
control in the off position and move the TWILIGHT
lever to any position but OFF.
2-54
This lever is located next
to the exterior lamp control.
It automatically turns the
lamps on and off by sensing
how dark it is outside.
If you move the lever all the way to the right, the lamps
will remain on for approximately three minutes after the
ignition has been turned to OFF. If you move the lever
so it is barely on, the lamps will go off quickly when
you turn the ignition switch out of OFF. You can
adjust the delay time from only a few seconds to
about three minutes.
If it's dark enough outside and the Twilight Sentinel
lever is off, a HEADLAMPS SUGGESTED message
will display on the Driver Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended (it's become dark
enough outside to require the headlamps and/or
other exterior lamps). Turning on the Twilight
Sentinel or turning the exterior lamp control to the
headlamp position will remove the HEADLAMPS
SUGGESTED message.
