(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 “Center vents”, “Side vents” and “Rear vents”.)\
 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
“OFF” 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.

These
are the controls added to the front air conditioning when
your vehicle is equipped with a rear air conditioning. The
controls for the rear passengers and for the front passengers
both work the same, so operation can be made with the
controls on either panel.
(a) Controls and Functions
This rear air conditioning is equipped with dustproof and
deodorant filter with photocatalyst. When light in the
xenon tube (ultraviolet rays) hits the filter, odious
ingredients adsorbed in the filter are oxidized and
decomposed to deliver clean air in the interior.

LO speed mode − Turns the fan at low speed.
HI speed mode − Turns the fan at high speed.

turn on if the front air conditioning is off.

cooler are adjusted automatically.

(d) Replacing the photocatalyst filter for therear seats
This rear air conditioning is equipped with dustproof and
deodorant filter with photocatalyst.
Replace the air filter when the use of rear air conditioning or air
purification function reduces air flow or deodorant
performance.
This filter is an interchangeable type. Do not clean the filter by
washing or air blowing. The use of filter after washing or
cleaning may cause a malfunction of the system. Be sure to
replace it with a new one.
The filter is located in the trunk.
Replace the filter using the following procedures.
1. Be sure to turn the ignition switch to “LOCK”.

3. Pull out the filter case toward you.
4. Replace the filter.
When you install the filter, face the filter surface (gray)
downward and fit the filter folds properly in the case as shown.
5. Install the filter in the reverse order of removal.
The gray surface in the filter may turn to yellow (yellow spots)
because of ultraviolet rays included in the light, however it is
no problem for use.

AIR CONDITIONING

When the ignition switch is turned on, the xenon tube comes
on even if the rear air conditioning or rear fan is not operating.
This
does not indicate a malfunction but is required for the long
use of the photocatalyst.
NOTICE
 Do not look into the xenon tube in the air purifier
through the filter slot and do not expose your skin
directly to the light in the xenon tube also. Although
the xenon tube scarcely issues less than 300nm
ultraviolet rays which are thought harmful for the
human body, some people may have symptoms such
as eye sore, vision trouble, skin inflammation, etc.
 Do not disassemble the air purifier , or it may cause a
malfunction. As some part in the purifier is under
high voltage, you may get an electric shock when you
touch it.
 The filters should be installed properly in position.
The use of rear air conditioning controls with the filter
removed may cause the malfunction of the rear air
conditioning controls.
 Turn on the air conditioning with a filter in position.
The activation without an filter may not only cause a
malfunction of the system but also dirty the interior
by spouting dust.
