Operating the system in the recirculation mode may
cause fogging of the vehicle’s windows when the
weather is cold and damp. To clear the fog, switch the
system to either the DEFOG or DEFROST mode and
increase the fan speed. To avoid re

-

fogging of the

windows, operate the system in the OUTSIDE 
AIR mode.

 FRONT: Press the FRONT defrost button to

quickly remove fog or frost from the windshield. This
setting directs most of the airflow to the windshield and
a small amount toward the lower and side window
outlets. The light on the button will come on and the
digital display will show the defrost mode symbol and
fan speed when the front defrost mode is being used.
Pressing FRONT defrost again will return the system to
the last operating mode and the air intake mode will be
in FRESH AIR.

If the system is in FRONT defrost when you shut the
engine off, it will restart in FRONT defrost unless the
engine is off for longer than 40 minutes. If the engine is
off longer than 40 minutes, the system will restart in the
operating mode you had set prior to FRONT defrost and
the air intake mode will be in FRESH AIR.

See “Rear Window Defogger” later in this section for
more information.

The automatic electronic dual climate control system
uses several sensors to control operation and 
display information.

This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of the
instrument panel.

The sensor monitors the sun’s solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.

Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.

This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor is
used for the outside air temperature readings shown 
on the digital display for the automatic climate 
control system.
