A method for operating a display system in a vehicle (03) when driving into a parking space (06), uses a camera (01) with an image processing unit in which the image data obtained by the camera (01) can be processed and a display screen (02) in the interior of the vehicle. After the vehicle has moved to the vehicle position in which the first parking-space icon (07) has been brought to overlay the parking space (06) shown in the real-time image, a second parking-space icon (09) is faded into the real-time image on the display screen (02) by the image processing unit, with this second parking-space icon (09) in the real-time image in true scale indicating a region which after moving along a first segment (15) of the travel path (14) towards the parking space (06) must be brought to overlay the parking space (06) shown in the real-time image. After the vehicle has moved to the vehicle position in which the second parking-space icon (09) has been brought to overlay the parking space (06) shown in the real-time image, a third parking-space icon (11) is faded into the real-time image on the display screen (02) by the image processing unit, with said third parking-space icon (11) in the real-time image in true scale indicating a region which after moving along a second segment (16) of the travel path towards the parking space (06) must be brought to overlay the parking space (06) shown in the real-time image.
