Step I or II is switched on by pressing appropriate symbol once. At the same time, in step I one LED illuminates and in step II both LEDs illuminate. By pressing the same symbol twice, heated seats are switched off.

Switch-on time of both heater steps is limited by rear HS control module (N25/6). Step II is automatically switched to step I after approx. 5 min. After approx. 30 ±5 minutes, heated seats switch off automatically.

When switching off ignition (position 0) automatic heater process is interrupted. When switching on ignition again left or right rear heated seat (HS) switch (S51/3, S51/4) must be re-actuated.

Heater elements (seat backrest/cushion) are switched in parallel. In step I actuation of heater element is from front HS control module (N25/5). Switch-on time is approx. 30%.

If battery voltage is below 11 V, heated seats are automatically shutoff through rear HS control module (N25/6) and LEDs in switches (S51/3, S51/4) flash.
