244 3-1. Using the air conditioning system and defogger
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for
an extended period.
■ Window defogger feature
In order to prevent the windows from fogging up, recirculated air mode may
automatically switch to outside air mode if the ambient temperature drops.
This feature can be cancelled by pushing and holding the air circulation
mode switch for longer than 2 seconds. The feature will be reactivated when
the engine switch is turned to the “ACC” or “LOCK” position.

For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the temperature setting.
■ When the indicator light on
flashes
Press
and turn off the air conditioning system before turning it on
once more. There may be a problem in the air conditioning system if the indi-
cator light continues to flash. Turn the air conditioning system off and have it

NOTICE
■
Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alka-
line solutions, dye, bleach or other detergent. Doing so may discolor the
vehicle interior or cause streaks or damage to painted surfaces.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration o\
f
leather surfaces.
●Remove any dust or dirt on leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
■ Cleaning the inside of the rear wi ndow and the rear quarter windows
● Do not use glass cleaner to clean the rear window and the rear quarter
windows, as this may cause damage to the rear window defogger heater
wires or print type antenna (if equipped). Use a cloth dampened with luke-
warm water to gently wipe the windows clean. Wipe the windows in
strokes running parallel to the heater wires or print type antenna (if
equipped).
● Be careful not to scratch or damage the heater wires or print type antenna
(if equipped).
