1. A method for operating a motor vehicle having a braking device for braking the motor vehicle, the braking device comprising a storage medium storing at least two functions, a first function in the at least two functions associated with a first triggering condition and a first limiting time value, and a second function in the at least two functions associated with a second triggering condition and a second limiting time value, wherein the first limiting time value is larger than the second limiting time value, wherein the method comprises steps of:
forecasting an anticipated time period until a reduction in speed or braking of the motor vehicle, triggered by a driver assistance system or by the driver of the motor vehicle, depending on at least one of: vehicle data relating to the motor vehicle and environmental data relating to the motor vehicle environment,
determining whether the anticipated time period is below the first limiting time value assigned to the first function, and, upon the anticipated time period falling below the first limiting time value, determining whether the first triggering condition is satisfied;
upon satisfaction of the first triggering condition, triggering a first function of the braking device;
determining whether the anticipated time period is below the second limiting time value assigned to the second function, and, upon the anticipated time period falling below the second limiting time value, determining whether the second triggering condition is satisfied; and
upon satisfaction of the second triggering condition, triggering a second function of the braking device, comprising one or both of: performing the second function at a same time as the first function and performing the second function after the first function;
wherein the first function of the braking device controls a first actuator and the second function of the braking device controls a second actuator different from the first actuator.
