recirculated air mode is used.

■

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

mode be set to outside air mode and

the fan speed to any setting except

off.

■

Outside/recirculated air mode

●

Setting to the recirculated air

mode temporarily is recom-

mended in preventing dirty air

from entering the vehicle interior

and helping to cool the vehicle

when the outside air temperature

is high.

●

■

Ventilation and air conditioning

odors

●

To let fresh air in, set the air condi-

tioning system to the outside air

mode.

●

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 out-

side 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 con-

ditioning system is started in auto-

matic mode.

●

When parking, the system auto-

matically switches to outside air

mode to encourage better air cir-

culation throughout the vehicle,

helping to reduce odors that occur

when starting the vehicle.
