INFORMATION

When the “ENGINE START STOP” switch is turned on, the air conditioning system settings will be set to those that were in use the last time the “ENGINE START STOP” switch was turned off. Air conditioning system settings are memorized individually on each electronic key, so the settings reproduced will be specific to the key that is used.

During use, various odors from inside and outside the vehicle may enter into and accumulate 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 operation mode.

CAUTION

To prevent the windshield from fogging up

Do not use the windshield air flow button 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.

INFORMATION

Using automatic mode

Fan speed is adjusted automatically according to the temperature setting and ambient conditions.

As a result, the following may occur:

Immediately after the button is pushed, the fan may stop for a while until warm or cool air is ready to flow.

Cool air may flow to the area around the upper body when the heater is on.

Using the system in recirculated air mode

The windows will fog up more easily if recirculated air mode is used for an extended period.

Switching between outside air and recirculated air modes

Recirculated air mode or outside air mode may be automatically switched to in accordance with the temperature setting and the inside temperature.

When the outside temperature exceeds 75 F (24 C) and the air conditioning system is on

In order to reduce the air conditioning power consumption, the air conditioning system may switch to recirculated air mode automatically. This may also reduce fuel consumption.

Recirculated air mode is selected as a default mode when the “ENGINE START STOP” switch is turned to IGNITION ON mode.

It is possible to switch to outside air mode at any time by pushing the air intake control button.

Window defogger feature

Recirculated air mode may automatically switch to outside air mode in situations where the windows need to be defogged.

To turn the electric rear window and outside rear view mirror defogger on, push the button above.

The “ENGINE START STOP” switch must be in IGNITION ON mode.

The thin heater wires on the inside of the rear window and the heater panels in the outside rear view mirrors will quickly clear the surface.

Keep your hands off the mirror faces when the system is on.

The indicator light is on when the defogger is operating.

CAUTION

When the outside rear view mirror defoggers are on, do not touch the outside surface of the rear view mirror as it can become very hot and burn you.

The defoggers will automatically turn off after 15 to 255 minutes. The operation time changes according to the ambient temperature and vehicle speed.

If further defrosting or defogging is desired, simply actuate the switch again.

When the surface has cleared, push the button once again to turn the defogger off.

Continuous use may cause the battery to discharge, especially during stop−and−go driving. The defogger is not designed to dry rain water or to melt snow.

If the outside rear view mirrors are heavily coated with ice, use a spray de−icer before operating the system.

NOTICE

When cleaning the inside of the rear window, be careful not to scratch or damage the heater wires or connectors.
