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
5minutes.
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.
