R Set the temperature to 22 †.
R Only use the demisting func tion briefly until
the windscreen is clea ragain.
R Only use the air-recirculation mode briefly,
e.g. if ther eare unpleas anto utside odours
or when in atunnel. The windows could
otherwis emist up as no fresh air is drawn
into the vehicle in air-recirculation mode.
