that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burns or frost-
bite on unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary,
change the air flow using the air distribution
controls to direct the air away from the foot-
well air vents (

ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and

volume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off, see
