CAUTION

Do not adjust the mirror while the vehicle is moving. It may
cause the driver to mishandle the vehicle and an accident
may occur, resulting in personal injuries.

while in the FRONT WINDSHIELD mode, the mode then
returns to the last mode used.
CAUTION
Do not use the FRONT WINDSHIELD mode during cooled
air operation in extremely humid weather. The difference
between the temperature of the outside air and that of the
windshield could cause the outer surface of the windshield to
fog up blocking your vision.
If quick heating or cooling is desired ±
Obtain maximum power by turning the ºTEMPº knob fully.
At this time, ºMAX. HOTº or ºMAX. COLDº will appear on
the display.

conditioning off once it is no longer required. This will
improve fuel economy. The air conditioning can be used for
year±round automatic temperature control including cooling
and dehumidifying operation. If the air conditioning compressor does not operate, the
