lights up.
Push in lower switch portion;
position 2 = rapid heating, both

indicator lamp will stay on.
Turning off heater:
If one indicator lamp is on, press
in upper part of switch, position 1.
If both indicator lamps are on,
press in lower part of switch,

The heater automatically turns off
after approximately 30 minutes of

Notes:
When in operation, the seat
heater consumes a large amount
of power. It is advisable not to use
the seat heater longer than ne­
cessary.
The seat heaters may automati­
cally switch off if too many power
consumers are switched on at the
same time, or if the battery charge
is low. When this occurs, the in­
dicator lamp in the switch will
blink (both indicator lamps blink
during rapid seat heating). The
seat heaters will switch on again
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.
