CAUTION
Do not use the ºFRONT WINDSHIELDº button during
cooled air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
When you turn the ignition switch on after the removal
and installation of the battery terminal, the indicator light
may flash and the operating sound of the motor may be
heard. This does not indicate a malfunction.
You may hear the operating sound of the motor about 70
seconds after the ignition switch is turned off. This is not
also a malfunction.(c) Air filter
The air filter may clog after long use and reduce air flow.
You can inspect the filter easily.
When you inspect and replace the air filter, be sure to
turn off the fan.

2. Take out the air filter.
Inspect the lower surface of the filter. If it is just
moderately dusty, it may be cleaned by blowing
compressed air from the lower surface. Do not wash or
oil the filter.
If it is dirty, it should be replaced. To maintain the air
conditioning efficiency, replace the air filter according to
the maintenance schedule. (For scheduled
maintenance information, please refer to the separate
ºOwner's Manual Supplement/Maintenance
Scheduleº.)
NOTICE
Do not drive with the air filter removed, or the efficiency of air conditioning may be lost.

(d) 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 ºCenter ventsº, ºSide ventsº,
ºLower ventº and ºRear ventsº.)
 To help cool down the interior after parking 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 vehicle 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 fan speed control button
be pressed to anywhere except the ºOFFº button.
 If following another vehicle on a dusty road, or driving
in windy and dusty conditions, it is recommended that
the air intake control button be temporarily pressed in
to the RECIRCULATED AIR mode, which will close
off the outside passage and prevent outside air and
dust from entering the vehicle interior.
