Tap the left- or right-side steering wheel and seat button in the center display's climate bar to open the controls for steering wheel and seat heating.
If the vehicle is not equipped with ventilated seats or heated steering wheel (for the driver's side), the button for seat heating is directly accessible in the climate bar.
Tap the seat heating button repeatedly to select one of the four levels: Off, High, Medium or Low.
The level is changed and the set level is displayed in the button.
