Abstract

A method for operating a motor vehicle (1) having at least one driven axle (3) with a locking differential (10a), where when the motor vehicle (1) is driving and the locking differential (10a) concerned is engaged on at least one driven axle (3), it is checked whether the motor vehicle is driving round a curve. If it is found that the motor vehicle is driving round a curve, the engaged locking differential (10a) is actuated to disengage it and it is checked whether the locking differential (10a) concerned has in fact been disengaged. If it is found that the locking differential (10a) concerned has not been disengaged, the wheel of the driven axle (3) concerned on the outside of the curve is braked.
