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.
The air conditioning cools and dehumidifies air coming
into the vehicle. It also operates in defrost to help
remove moisture from the vehicle. The air conditioning
does not operate at temperatures below approximately
35 F to 40 F (2 C to 4 C). If the system is operating in
the AUTO mode, turning the air conditioning off will
delete AUTO from the digital display and show current
mode and fan settings. The AUTO button must be
pressed to return to the automatic mode operation.
See “Rear Window Defogger” later in this section for
more information.
Sensors
The Automatic Electronic Dual Climate Control
System uses several sensors to control operation and
display information.
Solar Load Sensor
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.
