AIR CONDITIONING
186This button allows the air intake to select the OUTSIDE AIR
mode automatically. This is to clean up the front view more
quickly. If you want to return the setting to the
RECIRCULATED
AIR mode, push the air intake control button
once again.
Push the “A/C” button for dehumidified heating or cooling. This
setting clears the front view more quickly.
CAUTION
Do not use the windshield air flow 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.
(c) Operating tips
 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.
 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 side vents and
rear vents. (See “(d) Center vents and side vents”.)
 On humid days, do not blow cold air on the windshield. The
windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
 Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
 On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on 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
be set to the OUTSIDE AIR mode and the fan speed to any
setting except “OFF”.

AUDIO
220
To clean a compact disc: Wipe it with a soft, lint−free cloth
that has been dampened with water. Wipe in a straight line
from the center to the edge of the disc (not in a circle). Do not
use a conventional record cleaner or anti −static device.
REAR SEAT AUDIO SYSTEM
The rear seat audio system is designed for the rear seat
passengers to enjoy the audio sound separately between
the front seats and the rear seats.
The rear seat audio system can be turned on with the rear
audio system controller even if the front audio system is off.
When the front audio is turned off, the rear audio system will be
turned off simultaneously.
The rear passengers can enjoy all the modes (AM and FM
radio, cassette tape player and compact disc player with
changer) with the rear seat audio system when a cassette tape
and a compact disc are loaded in the front audio system.
When the same mode is selected on the front and rear audio
systems at the same time, the system can be operated on the
front audio system.
If the radio mode is selected on the front and rear audio
systems at the same time, AM and FM modes cannot be
changed on the rear seat audio system.
