To idle your vehicle with the DRL off at night, 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. As with any vehicle, you should turn on the regular headlamp system when you need it. Press the fog lamp button again to turn off the fog lamps. If you turn on the high-beam headlamps, the fog lamps will turn off. They will turn back on again when you switch to low-beam headlamps. When the Twilight Sentinel® is on and the fog lamps are turned on, the fog lamps, headlamps and parking lamps will remain on. The ignition must be on for the fog lamps to operate. Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. Cornering Lamps The cornering lamps come on when the headlamps or parking lamps are on and you signal a turn with the multifunction lever. They provide more light for cornering. - (Fog Lamps): Press the button with this symbol on it, located next to the exterior lamp control, to turn the fog lamps on. When the ignition is on and you press the fog lamp button, a small indicator light in the fog lamp button, the LIGHTS ON and fog lamp indicator lights on the instrument panel cluster will come on to indicate that the fog and the parking lamps are on. 3-19
