The driver and front passenger can select separate automatic programs.

In order to be able to cater for the different heating/air conditioning preferences the automatic mode on the F01/F02 climate control offers a choice of 5 different levels of intensity for the automatic program.

Automatic mode is activated by pressing the AUTO button.

The intensity level is selected by repeatedly pressing the "Fan speed" rocker button when Automatic mode is active.

The "ALL" button can be used to synchronize the temperature, AUTO mode intensity or air flow rate and airflow distribution settings for all 4 zones with the settings for the driver.

The Residual feature is similar to the E70 in that it is operated by pressing the HIGH side of the driver's fan speed button.

Some of the possible control scenarios on the control panels of the climate control systems are illustrated below.
