■Air conditioning odors
●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 occurring:
• It is recommended that the air conditioning 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 AUTO mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning compres-
sor when the “AUTO” switch ON) can be changed.
(Customizable features →P. 7 8 2 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside 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.
