Operating tips  
D To cool off your Toyota after it has  
been parked in the hot sun, drive with  
the windows open for a few minutes.  
This vents the hot air, allowing the air  
conditioning to cool the interior more  
quickly.  
D Make sure the air intake grilles in front  
of the windshield are not blocked (by  
leaves or snow, for example).  
D On humid days, do not blow cold air  
on the windshield. The windshield could  
fog up because of the difference in air  
temperature on the inside and outside  
of the windshield.  
D Keep the area under the front seats  
clear to allow air to circulate through-  
out the vehicle.  
D On cold days, set the fan speed to  
high for  
a
minute to help clear the  
intake ducts of snow or moisture. This  
can reduce the amount of fogging on  
the windows.  
D When driving on dusty roads, close all  
windows. If dust thrown up by the ve-  
hicle is still drawn into the vehicle after  
closing the windows, it is recommended  
that the air intake selector be set to  
FRESH and the fan speed selector to  
any setting except “OFF”.

D If following another vehicle on a dusty  
road, or driving in windy and dusty  
conditions, it is recommended that the  
air intake selector be temporarily set to  
RECIRCULATE, which will close off the  
outside passage and prevent outside  
air and dust from entering the vehicle  
interior.
