Depending on the heating level, up to three indicator lamps will light up. If all the indicator lamps are off, AIRSCARF is switched off.
When switching on, the blower will start up only after a preheating phase lasting a few seconds.
After switching off, the blower will continue to run for a few seconds to cool down the heating elements.
If the vehicle battery voltage is too low, AIRSCARF may switch off.
Make sure that there are no objects covering the air intake on the back of the head restraint.
Make sure that objects do not enter the air inlet and outlet grilles in the head restraints.
