■When the indicator light on “A/C” flashes
Touch “A/C” and turn off the air conditioning system before turning it on once more.
There may be a problem in the air conditioning system if the indicator light contin-
ues to flash. Turn the air conditioning system off and have it inspected by your Lexus
dealer.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent 12 volt battery discharge
Do not leave the automatic air conditioning system on longer than necessary when
the engine is off.
