ately after the automatic mode switch is

pressed or “AUTO” is selected.
Cool air may blow around the upper body

even when the heater is on due to sunlight.

recirculated air modes.
When the dehumidification function is off,

and the fan is operating, turning automatic

mode on will activate the dehumidification

function.

In S-FLOW mode, priority for the air-
flow is given to the front seats, reducing
the airflow and air conditioning effect
on the rear seats. When in S-FLOW
mode, airflow from the rear air condi-
tioning system is stopped.
Operation in S-FLOW mode differs
according to the following conditions:
 Priority is given to the driver’s seat

Manual S-FLOW mode: When no
passenger is judged to be in the
front passenger seat.
Automatic S-FLOW mode: When
no passengers are judged to be in
the front passenger seat or rear

■

How the system judges if a passenger is

in the vehicle when in S-FLOW mode

In S-FLOW mode, the system judges if a

passenger is in the vehicle as follows:

●

Front passenger seat: A passenger is

judged to be in the front passenger seat

when the system detects an object on the

front passenger seat, fastening of the

front passenger seat belt, changing of the

set temperature for the front passenger

seat, changing of the air outlets for the

front passenger seat or the opening and

closing of the front passenger door.

(However, when only opening and clos-

ing of the front passenger door is

detected, the system will judge that a pas-

senger is not in the front passenger seat

after the vehicle speed reaches approxi-

mately 12 mph (20 km/h) or more.)

●

Rear seats: A passenger is judged to be in

a rear seat when the system detects the

opening and closing of a rear door (auto-

matic S-FLOW mode only) or the opera-

tion of the rear air conditioning control

screen on the Rear Multi Operation

Panel.

■

Operation of automatic S-FLOW mode

When the system is operating in automatic

S-FLOW mode, if the system detects the

opening and closing of a rear door or the

operation of the rear air conditioning con-

trol screen on the Rear Multi Operation

Panel, S-FLOW mode will be disabled. To

enable S-FLOW mode, select the S-FLOW

mode switch. (In this case, the system will

operate in manual S-FLOW mode.)

■

Changing from manual S-FLOW mode

to automatic S-FLOW mode

Select the S-FLOW mode switch to dis-

able S-FLOW mode.

Turn the engine switch off.

After 60 minutes have elapsed, change

the engine switch to ON mode.
