Heating, ventilation, air-flow and the optional air-conditioning merely require the setting of a selector by the driver. The temperature is thereafter maintained at the required level automatically. In hot weather, additional ventilation is provided by a booster fan.

In the 5-6 seat Sedan without central partition, both front seats are fully adjustable horizontally and vertically by a single button. The same button adjusts the angle of the backs of these seats down to the horizontal. In limousines with central partition, the horizontal front seat adjustment is hand operated.
To ensure the comfort of both tall and short drivers the position of the steering wheel can be adjusted after turning the padded wheel boss.
The rear seat is hydraulically adjustable. The seat can be moved forward and the reclining back adjusted to the desired angle.
A lever on the steering column adjusts the shock absorbers to meet the variations in different road surfaces.
With this pull button, road clearance can be increased while driving by 2.0" (50 mm), when required.
A selector on the dashboard governs the heating, ventilation and air flow (air conditioning is optional). Louvers on the air-intake grill in front permit directional control of the air stream.
The parking brake is foot operated. When driving off from standstill, this brake is released automatically. It can also be released by means of a small hand lever.
The lightest touch is sufficient to close the doors silently. They are hydraulically assisted and close securely. Locking the driver's door automatically locks all doors, the trunk lid and the filler cap.
The illustration shows one of the control panels of the hydraulic push-button system. Unlike the more widely used electrically operated systems, the hydraulic system has the advantage of greater reliability and safety. In addition, its operation is completely silent.
