A method of manually overriding automatic activation of an automatic headlight control system for a motor vehicle, headlamps operable in a high beam state and a low beam state, a high/low beam switch movable from a neutral position to a latched position and from a neutral position to a non-latched position for controlling the state of the headlamps and a headlamp on/off switch comprising a multi-position switch with at least a selectively automatic headlamp position is disclosed. The system includes forward-facing sensor for collecting light emanating from for instance a second vehicle, and a controller for controlling, when the headlamp switch is detected as being in the automatic headlamp position, the headlamp states as a function of the sensed intensity of the beam of light emanating from said second vehicle. The method comprises the steps of: monitoring the states of the headlamps when the headlamp on/off switch is in the automatic position, causing the controller to initiate an override mode if the high beam states is detected (step) and said high/low beam switch is detected as moved from the neutral position to the non-latched position whereupon the controller changes the headlamps to the Low state (step) when the High/Low beam switch is subsequently released to the neutral position. Such a method ensures the use of conventional stalk.

A method for inhibiting automatic actuation of an electric parking brake (EPB) system of a motor vehicle is disclosed. The vehicle has an ignition switch for receiving an ignition key so as to mobilize or immobilize the vehicle. The EPB system includes an EPB mechanism for applying an actuating force to a park brake of the vehicle, an EPB control module for automatically applying the force when at least the ignition key is detected as removed from the ignition switch and an EPB control switch. The EPB control switch can be moved towards two instable positions from a neutral position respectively a brake release position and a brake apply position so as to apply or release the park brake. To inhibit the automatic actuation of the park brake, the driver has to complete within a specific time period the cycle of turning the ignition from off to on to off, pressing and maintaining the EPB control switch into the brake release position, removing the ignition key and releasing the EPB control switch after at least a predetermined time period. Such cycle of actions will be interpreted by the EPB control module as a wish to not apply the park brake.
