Selection of interior temperature for the driver and passenger zone in increments of 1°C between 16°C and 27°C (or between 60°F and 80°F). An indicator LED in the temperature knob indicates the selected temperature.

The following values are used when the ignition is switched on:

Using the diagnostic tool, the ACC unit can be adjusted to increase or decrease the temperature in the left and right temperature zone compared to that which has been set via the steering wheel control.
