These controls are overhead, on the control panel located
behind the front seats. A rear-seat passenger can use
these controls to personally adjust the temperature and
the fan speed for the rear-seating area.
This knob is located below
the main climate-control
system on the instrument
panel switchbank. Use
this knob to adjust the fan
speed for the rear-seat
passengers, from the
front-seating area.
The fan knob located on the switchbank must be turned
to R (Rear) to allow the rear-seat passengers to use
the controls located on the control panel in the
rear-seating area. If this fan knob is not in R when the
FAN or TEMP button is pressed, the rear control
panel will show DISABLED.
Directing the Airflow
To direct the airflow to the rear-seating area, use the
right knob located on the main climate-control panel.
