Ventilation and air conditioning odors ●
To let fresh air in, set the air conditioning system to the outside air mode.●
During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. 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 automatic mode.
CAUTION■
To prevent the windshield from fogging up
Do not use
during cool air operation in ex tremely 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 off.
