4 Massage function (PULSE) The multicontour backrest is equipped with a massage function to help prevent fatigue during longer journeys. The PULSE function inflates and deflates the air cushions in the backrest rhythmically. An indicator lamp on the switch lights up when the PULSE function is switched on. The PULSE function switches off automatically after approximately 5 minutes. Note: If the top cushion is inflated, only the middle air cushion is inflated and deflated. Seat heater The seat heaters can be switched on with the electronic key in starter switch positions 1 or 2. The buttons are located on each door. Note: When in operation, the seat heater consumes a large amount of electrical power. It is not advisable to use the seat heater longer than necessary. The seat heaters may automatically switch off if too many power consumers are switched on at the same time or if the battery charge is low. In this case, one or both indicator lamps will blink. The seat heaters switch back on again automatically as soon as sufficient voltage is available. If the blinking of the indicator lamps is distracting to you, the seat heaters can be switched off.
