This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior.

When two different drivers share the XT5, the optional memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position and outside mirror angle. The Q3 doesn’t offer a memory system.
