Each time you push the air intake control but-
ton, the mode changes in order from the RE-
CIRCULATED AIR mode to AUTOMATIC
mode to OUTSIDE AIR mode, then back to
the RECIRCULATED AIR mode. Each indi-
cator light shows which mode is now se-
lected.
1
RECIRCULATED AIR mode ± If quick
circulation of cooled air is desired, se-
lect this mode.
2
EXHAUST GAS AUTOMATIC mode ±
If the outside air contains harmful sub-
stances like exhaust gas (i.e., when the
vehicle running just in front of your ve-
hicle accelerates rapidly), the system
changes automatically from the OUT-
SIDE AIR mode (with indicators
2
and 3
on) to the RECIRCULATED
mode (with indicators
1
and 2
on).
3
OUTSIDE AIR mode ± The system will
take fresh outside air into the vehicle.
For normal use, it is best to keep the air in-
take control button set to OUTSIDE AIR
mode. If recirculated air is used during heat-
ing, the windows will fog up more easily.
Turning off the air conditioning manually will
cancel the EXHAUST GAS AUTOMATIC
mode. If you select the ªAUTOº mode during
fan operating, the air conditioning turns on
and the EXHAUST GAS AUTOMATIC mode
will operate.To change the sensitivity of the sensor
switching between the RECIRCULATED
and OUTSIDE AIR in the AUTOMATIC
mode, push the air intake control button
for a few seconds. The display changes
as illustrated below.
The sensitivity of the sensor can be adjusted
only while the vehicle has been stopped.

If it is dirty, it should be replaced. To maintain
the air conditioning efficiency, replace the air
filter according to the maintenance sched-
ule. (For scheduled maintenance informa-
tion, please refer to the ºOwner's Manual

(e) Operating tips
Make sure the air inlet grilles in front of
the windshield are not blocked by leaves
or other obstructions.
If air flow control is not satisfactory,
check the dashboard vents. (See ºCen-
ter ventsº, ºSide ventsº, ºLower ventº
and ºRear ventsº.)
To help cool down the interior after park-
ing in the hot sun, drive for the first few
minutes with the windows open. After
the excess heat has blown away, close
the windows.
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 control button be left
to the OUTSIDE AIR mode and the air
flow control switch be selected to any-
where except the ºOFFº button.
