Heating and ventilation system without air conditioning

Air distribution

Recirculation interior air enters through panel vents. Very little air is drawn from outside. Use this
position to avoid circulating dense exhaust gases (as when driving through a tunnel). Do not use this
position for more than 10-15 minutes as very little fresh air will be supplied.

Air from panel louvers.

On the system without air conditioning these two symbols represent identical functions. (With air
conditioning the upper sign position emits cooled air).
