SIENNA_OM_OM08007U_(U)
WARNING
■To prevent the windshield from fogging up
●Do not use   during cool air operat ion 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, block-
ing your vision.
■ To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers (vehicles with outside rear view mirror defoggers) are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front  pillars  when  the  windshield  wiper  de-icer  is  on.  (vehicles  with  wind-
shield wiper de-icer)
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
●Do not place anything on the instrument
panel  which  may  cover  the  air  outlets.
Otherwise,  air  flow  may  be  obstructed,
preventing  the  windshield  defoggers
from defogging.
