Heating or cooling cannot be hastened by selecting a higher or lower temperature than the actual desired temperature.
Current temperature for each side is shown in the centre console's display screen.
The temperatures on the driver and passenger sides can be set independently. Repeatedly press L/R in the button to select the setting for left, right or both sides. Set the temperature using the knob - the selected temperature for either side is displayed in the centre console display.
The temperature in the passenger compartment can be adjusted with the knob.
