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. Fully functional daytime running lamps are required on all vehicles first sold in Canada. The DRL system will make the low-beam headlamps come on at reduced intensity when the following conditions are met: It is still daylight and the ignition is on, the exterior lamp control is in the off position and the transaxle is not in PARK (P). When DRL are on, only your high-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. When the Twilight Sentinel@lever is on and it's dark enough outside, the high-beam headlamps at reduced intensity will turn off and normal low-beam headlamp 3-16 Turning on the Twilight Sentinel@ or the headlamps will deactivate the DRL and remove the HEADLAMPS SUGGESTED message.
