applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate
once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking
brake is applied.
And battery saver system is controlled by the headlamp battery saver control unit and BCM (body control
module).
