Method to operate a driver assistance system of a motor vehicle, having the steps: - identifying a viewing direction of a driver of the motor vehicle; - determining a lane change intention of the driver by means of the identified viewing direction; - operating the driver assistance system taking into consideration the determined lane change intention; characterised in that - by means of the identified viewing direction, it is determined whether a glance of the driver toward respectively predetermined mirrors (20, 22, 24) of the motor vehicle according to a first predetermined sequence or according to a second predetermined sequence has occurred, wherein the first predetermined sequence comprises a glance of the driver toward an inner mirror of the motor vehicle and a subsequent glance toward a left outer mirror of the motor vehicle and the second predetermined sequence comprises a glance of the driver toward the inner mirror of the motor vehicle and a subsequent glance toward a right outer mirror of the motor vehicle; - if a glance according to the first predetermined sequence has been determined, a lane change intention to the left is determined; - if a glance according to the second predetermined sequence has been determined, a lane change intention to the right is determined; - the respective lane change intention is only then determined if, additionally within a predetermined time period before, during and/or after the respective glance according to any one of the predetermined sequences, a touch of a indicator lever of the motor vehicle has been determined, wherein upper- and lower-side units are arranged on the indicator lever by means of which a corresponding touch of the indicator lever is identified; - a lane change intention to the left is only then determined if a touch of an upper side of the indicator lever has been determined; - a lane change intention to the right is only then determined if a touch of a lower side of the indicator lever has been determined. - identifying a viewing direction of a driver of the motor vehicle; - determining a lane change intention of the driver by means of the identified viewing direction; - operating the driver assistance system taking into consideration the determined lane change intention; - by means of the identified viewing direction, it is determined whether a glance of the driver toward respectively predetermined mirrors (20, 22, 24) of the motor vehicle according to a first predetermined sequence or according to a second predetermined sequence has occurred, wherein the first predetermined sequence comprises a glance of the driver toward an inner mirror of the motor vehicle and a subsequent glance toward a left outer mirror of the motor vehicle and the second predetermined sequence comprises a glance of the driver toward the inner mirror of the motor vehicle and a subsequent glance toward a right outer mirror of the motor vehicle; - if a glance according to the first predetermined sequence has been determined, a lane change intention to the left is determined; - if a glance according to the second predetermined sequence has been determined, a lane change intention to the right is determined; - the respective lane change intention is only then determined if, additionally within a predetermined time period before, during and/or after the respective glance according to any one of the predetermined sequences, a touch of a indicator lever of the motor vehicle has been determined, wherein upper- and lower-side units are arranged on the indicator lever by means of which a corresponding touch of the indicator lever is identified; - a lane change intention to the left is only then determined if a touch of an upper side of the indicator lever has been determined; - a lane change intention to the right is only then determined if a touch of a lower side of the indicator lever has been determined.
