The rear seat unit is of one-piece construction. Three head restraints and three inertia-reel seat belts ensure the safety of the occupants. The outer rear seats are also equipped with belt tensioners and belt force limiters, as well as head restraints adjustable for height and angle. ISOFIX, the standardised attachment system for child seats, is included as part of the standard specification.

Even more comfort: THERMOTRONIC now with climate modes

As part of the standard specification, all Mercedes-Benz C-Class models include the two-zone THERMATIC automatic climate control. Yet more climate comfort is available courtesy of the optional luxury automatic climate control THERMOTRONIC, which allows individual temperature settings for three zones - for the driver, the front passenger and the rear passengers. What are known as the THERMOTRONIC's climate modes constitute a new feature in the C-Class: the car occupants can select "Diffuse", "Medium" or "Focus" settings at the push of a button and thus adjust the air quantity and air distribution to their liking without having to leave the convenient automatic mode.

In "Diffuse" mode, for example, the THERMOTRONIC system operates with a low air speed and distributes the air over a wide area so that there are fewer draughts. In "Focus" mode, meanwhile, the air outlets in the centre area of the dashboard are used for the most part, meeting the need for a direct flow of a larger quantity of air.
