Air-conditioned seats for the driver and front passenger are standard on the new CL-Class. Featuring 3-stage seat heating and 3-stage seat ventilation, they are the ultimate in seating technology. Adjusted by controls in the front door, air is drawn from the cooler, lower area of the passenger compartment and transferred uniformly to the seat cushion and backrest. The finely perforated leather upholstery absorbs perspiration, to create a pleasant microclimate all round: in effect, the seats 'breathe'.
