AIR CONDITIONING
ISF_IS_ISC_Navi_EE
INFORMATION
Automatic air intake change mode
• In automatic mode, the system auto-
matically switches between recircu-
lated air and outside air modes
according to whether the system
detects harmful substances such as
exhaust gas in the air outside.
• When the retractable hardtop is
opened, recirculated air mode is
automatically selected. (IS250C)
When the indicator light on “A/C”
flashes
• Touch “A/C” to turn off the air con-
ditioning system 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 any autho-
rized Lexus dealer or repairer, or
another duly qualified and equipped
professional.
Air conditioning filter
• The air conditioning filter may clog
after long use. The filter may need
to be replaced if the air flow of the
air conditioner and heater experi-
ences extreme reductions in operat-
ing efficiency, or if the windows
become to fog up easily. (For
details, refer to “Owner’s Manual”.)
