The massage action is done with air cushions, which can be adjusted to a firm or gentle setting. When the setting has been made, the massaging action is carried out in cycles as follows: massage 6 minutes - pause 4 minutes - massage 6 minutes, etc. When the button is in the center position or if the ignition is in position 0, the massage function is switched off. The lumbar support uses the same air cushions as the massage function. The button can be used to adjust the amount of support in four directions, as shown in the illustration. Lumbar support can be only be adjusted when the massage function is switched off. A memory function stores the lumbar support setting and this support will resume after the massage function has been switched off or after the vehicle has been parked for an extended period of time. 103
