system and is normal.
· The air conditioning system functions only at temperatures just above 39° F (4° C).
· RECIRCULATION: Use this function if the outside air is contaminated with exhaust gases, smoke,
etc or to heat/cool the car quickly. When Recirculation is activated, no air is drawn into the passenger
compartment from the outside. Recirculation should not be activated for more than 10-15 minutes at a
time. If your windows begin to fog or mist, check that the recirculation function is NOT engaged.
NOTE: When driving with the sun roof or windows open, to help maintain stable passenger
compartment temperature, use the blower control to manually regulate the blower speed.
· If the panel vents are open, a certain amount of air will always flow through, regardless of the position
the function dial is in. To increase the flow of air to either
the floor or the windows, close the panel vents and open the outer vents.
· The panel vents may emit some condensation when the air conditioning is initially switched on and is
normal.
This may occur if the ambient temperature and humidity are high.
