Download The standard equipment for model 129 includes a hydraulically actuated roadster top and a coupe roof. The switch for opening and closing the top is located on the center console. The top can be opened within approx. 30 seconds and stored in the top compartment by pressing the switch toward the rear and holding in this position or removed from the top compartment and closed by pressing the switch toward the front and holding in this position (when closing it may be necessary to “help” slightly by manually guiding the front top frame into the initial catch on the front top locks). For this purpose roll down side windows and put down roll bar and return to initial position afterward. The top moves only as long as the switch is actuated. The motion can be interrupted at any desired point and then continued or reversed. During an interruption the top is locked hydraulically so that it cannot fall down. The lock is released when the ignition is switched off and the top can be moved freely. Five opening/closing operations are possible immediately one after another.
