Air conditioning odors

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:

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.
