Air conditioning odors

• 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 extremely humid weather. The difference 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 12-volt battery discharge Do not leave the air conditioning system on longer than necessary when the hybrid
system is off.
