"A/C" button (on some models)
To turn on the air conditioning, press the
"A/C" button. The "A/C" button indicator
will come on. To turn the air conditioning
off, press the button again.

is a problem in the air conditioning system
or the cool box, and the air conditioning
automatically shuts off. If this happens,
take your vehicle to your Toyota dealer for
service.
