SEQUOIA_OM_USA_OM0C047U■
When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ When the indicator light on flashes
Press
to turn off the cooling and dehumidification function and turn it on
again. There may be a problem in the air conditioning system if the indicator
light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.

be emitted from the vents.

mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
