Notes:
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. When this occurs,
the indicator lamps in the switch will blink for
approximately 30 seconds.
Within this time the seat heaters will switch on again
automatically as soon as sufficient voltage is available.
After approximately 30 seconds without sufficient
voltage the seat heaters switch off (indicator lamps go
out).
