Seat ventilation system
(optional, standard on model S 600)

Seat ventilation can be activated manually with the
electronic key in starter switch positions 1 or 2, or by
the summer opening function (driver’s seat only), see
page 43.
Notes:
When in operation, the seat ventilation system
consumes a large amount of electrical power. It is not
advisable to use the seat ventilator longer than
necessary.The seat ventilators 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
more indicator lamps will blink.
The seat ventilation 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 ventilators can be switched off.
The maximum ventilation level (level 3) is automatically
selected if the driver’s seat ventilation is activated by
the summer opening function, see page 43.
