5-2. Using the air conditioning system and defogger
■Air conditioning odors
●During use, various odors from inside an d outside the vehicle may enter into and
accumulate in the air condit ioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning 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 immedi-
ately after the air conditioning system is started in automatic mode.
■Air conditioning filter
P. 6 5 7
■Customization
Settings (e.g. exhaust gas sensor sensitivity) can be changed.
(Customizable features: P. 7 9 3 )
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outs ide air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
■Humidity sensor
Follow these points to avoid damaging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sensor or subject it to strong impacts
