Interior motion sensor

Operation

If the interior motion sensor is primed and the auxiliary heating system more switches on, a false alarm may occur as a result of interior temperature monitoring. In this case, either deactivate the interior motion sensor or switch off the auxiliary heating.

Otherwise the interior motion sensor will not be primed.

Make sure that nothing (such as mascots or coat hangers) are hanging on the rear-view mirror or on the grab handles on the roof lining.
