extended period. ■
Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched in accor-
dance with the temperature setting and the inside temperature. ■
When the outside temperature exceeds 75°F (24°C) and the air conditioning
system is on ●

system may switch to recirculated air mode automatically. This may also reduce
fuel consumption. ●

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 “AUTO” mode.■
