| Description and Operation Daytime Running Lamps CAUTION:On vehicles with autolamps, retrofitting with daytime running lamps is not permissible, as otherwise, the engine cannot be stopped when the lighting is switched on. CAUTION:On vehicles with autolamps, the daytime running lamp fuse must not be fitted, as otherwise, the engine cannot be stopped when the lighting is switched on. In areas where daytime running lamps (DTRL) are a legal requirement, the Generic Electronic Module (GEM) switches the dipped beam and the side lights on whenever the ignition switch is in the position "II" or "III" . On vehicles with conventional lamps (with a spiral-wound filament) the dipped beam operates at 90 % of its normal brightness when the supply voltage is provided through a DTRL relay and a specific resistor wire. On vehicles with gas discharge headlamps the dipped beam operates at the normal intensity via the standard dipped beam relay. The autolamp function is not available on vehicles with daytime running lamps, as the GEM can only be configured for one of these two options. |
