conditioning system on or off and override the automatic

mode on. An indicator light below the button comes on
to show that this mode is on. This mode recirculates
and helps to quickly cool the air inside the vehicle.
It can be used to prevent outside air and odors from
entering the vehicle. This mode cannot be selected
while in the defog or defrost modes. If you try to select
the recirculation mode, the indicator light flashes three
times and turns off.

Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced,
select the defrost mode.

passenger climate control systems on or off.

When the passenger climate control system is on, the
passenger temperature setting is displayed.

temperature setting off, the driver temperature setting
controls the temperature for the entire vehicle.
