■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.

mirror defoggers are operat-
ing
Do not touch the rear view mirror
surfaces when the outside rear
view mirror def oggers are on.

tributing to increased fuel effi-
ciency.

or enter/exit the vehicle, the sys-
tem cannot accura tely detect the

matic airflow co ntrol will not oper-
ate.
