2000 Cadillac Seville Owner's Manual - Page 105

When the Twilight SentinelR switch is on and it's dark enough outside, the high-beam headlamps (at reduced intensity) will turn off and normal low-beam headlamp operation will occur. When the Twilight Sentinel switch is on and it's bright enough outside, the regular lamps will go off, and the high-beam headlamps at reduced brightness will take over. If it's dark outside and the Twilight Sentinel control is off, a HEADLAMPS SUGGESTED message will display on the Driver's Information Center (DIC). This message informs the driver that turning on the exterior lamps is recommended even though the DRL are still illuminated. This message indicates that it has become dark enough outside to require the headlamps and/or other exterior lamps. Turning on the Twilight Sentinel or the headlamps will deactivate the DRL and remove the HEADLAMPS SUGGESTED message. If the parking lamps or the fog lamps were turned on instead, the DRL will still deactivate and the HEADLAMPS SUGGESTED message will continue to be displayed. To idle your vehicle with the DRL off, turn off the Twilight Sentinel and shift the transaxle into PARK (P). Placing your vehicle in PARK (P) disables the DRL. The DRL will stay off until you shift out of PARK (P). To drive your vehicle with the DRL off, turn off the Twilight Sentinel and manually turn on the parking lamps or fog lamps (if equipped). As with any vehicle, you should turn on the regular headlamp system when you need it. Fog Lamps (STS Only) Use the fog lamps for better vision in foggy or misty conditions. When you push the fog lamp button located next to the exterior lamps control, a small indicator light in the fog lamp button and the LIGHTS ON and fog lamp indicator lights on the instrument panel cluster will tell you that the fog lamps and the parking lamps are on. Pushing the fog lamp button again will turn them off. If you turn on the high-beam headlamps, the fog lamps will turn off. They'll turn back on again when you change to low-beam headlamps. You can use the fog lamp button to turn the fog lamps on or off when the parking lamps or headlamps are on. When the Twilight SentinelR is on and the fog lamps are turned on, the fog lamps, headlamps and parking lamps will remain on. 2-45
