Twilight SentinelR 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. 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
