In order to prevent the windshield from
fogging up when the outside air is cold,
the following may occur:
• Outside air mode does not switch to
recirculated air mode.
• The dehumidification function oper-
ates.
• The operation cancels after approxi-
mately 1 minute.
In rainy weather, the windows may fog
up. Press the windshield air flow but-
ton.
In extremely humid weather, the win-
dows may fog up.
The pollens are filtered out even if
/ micro dust and pollen filter but-
ton is turned off.
In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change.
• When stopped, or driving at low
speeds (less than 20 km/h)
• When the outside temperature has
changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
The dehumidification function may not
operate even when “A/C” is selected.During use, various odors from inside
and outside the vehicle may enter into
and accumulate in the air conditioning
system. This may then cause odor to be
emitted from the vents.
To reduce potential odors from occur-
ring:
• It is recommended that the air condi-
tioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time
immediately after the air conditioning
system is started in automatic mode.
The air conditioning filter may clog
after long use. The filter may need to be
replaced if the air flow of the air condi-
tioner and heater experiences extreme
reductions in operating efficiency, or if
the windows fog up easily. (For details,
refer to “Owner’s Manual”.)
Settings can be changed. (For details,
refer to “Owner’s Manual”.)
