Adjusting The On Times

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Information

The auxiliary heater has 3 independent memory locations. Thus 3 different ON times can be programmed for auxiliary heating or auxiliary ventilation.
But only one memory location can be activated.
The time at which heating or ventilation begins can be pre-set precisely to any time from one minute up to 24 hours.
The pre-selected ON time only remains effective for 24 hours.
