Two sensors located at the top of the windshield detect upward and forward light intensity. This makes it possible for the system to automatically perform functions such as activating low beam when you drive into a tunnel on a sunny day. Parking lights are turned off. Cars with xenon lights: The bulbs for DRL are in the inner of the two bulb holders in the bulb housing. The bulb is visible from the outside. Cars with halogen lights: These cars do not have a separate DRL bulb. Low beam instead shines with reduced output. A fault in the system will produce the following message on the Saab Information Display (SID): In cold and damp weather, the inside of the headlamp lens may temporarily mist up. This misting does not affect the function or service life of the light fitting. When the lamps are on, the mist will eventually disappear. Automatic light control malfunction. When the engine is started and the switch is in the AUTO position Cars with automatic transmission: DRL or low beam (which depends on the amount of daylight) comes on when the gear selector is moved out of the P position. The light goes out when the ignition switch is turned to the OFF position (engine is turned off). Cars with manual transmission: If the parking brake is applied when the engine is started, DRL or low beam (which depends on the amount of daylight) comes on when the parking brake is released. Otherwise, the light comes on when the ignition switch is turned to the ON position. The light goes out when the ignition switch is turned to the OFF position (engine is turned off). High beam cannot be activated in the DRL mode but headlight flasher can. Light switch
