forced into the seat belt by a seat or back-
rest which is not engaged. The seat belt can no longer offer the intended level of pro-
tection and could even cause injuries.

there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.

control: use the ZONE function to adopt the
temperature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above

control: use the "residual heat" function if
you want to heat or ventilate the vehicle inte- rior when the ignition is switched off. The
residual heat function can only be activated or
deactivated with the ignition switched off.
