Problems with the seat heating or seat ventilation
ProblemPossible causes/consequences andMSolutions
The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on.The on-board voltage is too low because too many electrical consum-
ers are switched on.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation can be switched back on manually.
AIRSCARF
GWARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot.
Driver's and front-passenger seat
The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.

cate the heating level you have selected.

up. The blower starts up after a preheating
phase of seven seconds.

until all the indicator lamps go out. You can use the adjustable fins on the head
restraint to adjust the height of the current of air
