To prevent the windshield from fogging up ●
Do not use during cool air operation in extremely humid weather. The differ-
ence 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.
■
To prevent burns ●
Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on. ●
Do not touch the glass at lower part of the wi ndshield or to the si de of the front pillars
when the windshield wiper de-icer is on. (if equipped)
NOTICE ■
To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is
off. ●
Do not place anything on the instrument
panel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
