Seat heating
The temperature setting progresses one step through its control sequence each time you press the button. The maximum temperature is reached when three LEDs are lit.
To switch off: press and hold the button.
The temperature is reduced, if need be, down to no heat in order to reduce the load on the battery.
The LEDs remain lit.
