yellowblue Parking Lamps Pull the lamp control knob out to the first stop to turn on the parking and taillamps, sidemarker lamps and instrument panel lights. Push the control knob all the way back in to turn the lamps and lights off. The wiper-activated headlamps will deactivate if you turn off the Twilight Sentinel or if the windshield wipers have been turned off for a period of one or two seconds. Lamps on Reminder You will hear a warning chime if you open any door while leaving the lamps on, if the manual headlamp control is activated. An exception to this is when you're using Twilight Sentinel. Headlamps Pull the knob out all the way to turn on the headlamps. Push the control knob all the way back in to turn the lamps and lights off. Cluster lighting will dim only when it is dark outside. The instrument panel backlighting will activate whenever the lamps or lights or turned on. Wiper-Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers have been in use for approximately 20 seconds. In order to operate the wiper-activated headlamps, the Twilight SentinelR must be turned on. This feature lights the way in poor weather and it also makes your vehicle more visible to other drivers. If the wiper-activated headlamps are on and the ignition switch is turned off, the wiper- activated headlamps will immediately turn off. Daytime Running Lamps Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. The DRL system will make the low-beam headlamps come on at reduced brightness when: D the ignition is on, D the headlamp switch is off and D the transaxle is not in PARK (P). When DRL are on, only your low-beam headlamps (at reduced brightness) will be on. No other exterior lamps such as the parking lamps, taillamps, etc. will be on when the DRL are being used. Your instrument panel won't be lit up either. 2-43
