5-2. Using the air conditioning system and defogger

■

Automatic mode for air intake control (vehicles with rear air conditioning system)

In automatic mode, the system detects exhaust gas and other pollutants and automati-

cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic

mode on will activate the dehumidification function.

■

When the outside temperature is low

The dehumidification function may not operate even when “A/C” is touched.

■

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning system to the outside air mode.

●

During use, various odors from inside and outside the vehicle may enter into and accu-

mulate in the air conditioning system. This may then cause odor to be emitted from the

vents.

●

To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior

to turning the vehicle off.

• The start timing of the blower may be delayed for a short period of time immediately

after the air conditioning system is started in automatic mode.

WARNING

■

To prevent the windshield from fogging up

●

Do not use windshield defogger switch during cool air operation in extremely humid

weather. The difference between the temperature of the outside air and that of the

windshield can cause the outer surface of the windshield to fog up, blocking your

vision.

■

To prevent burns

●

Do not touch the rear view mirror surfaces when the outside rear view mirror defog-

gers are on.

●

Do not touch the glass at lower part of the windshield or to the side of the front pillars

when the windshield wiper de-icer is on. (vehicles with windshield wiper de-icer)

NOTICE

■

To prevent battery discharge

Do not leave the air conditioning system on longer than necessary when the engine is

off.

■

When repairing/replacing parts of the air conditioning system

Have repair/replacement performed by your Lexus dealer. When a part of the air con-

ditioning system, such as the evaporator, is to be replaced, it must be replaced with a

new one.

●

Do not place anything on the instrument

panel which may cover the air outlets. Other-

wise, air flow may be obstructed, preventing

the windshield defoggers from defogging.
