FORD 2012 F-550 v.2 - Manual (Page 84)

• To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out”.
• A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C in
the max A/C position, reduce blower fan speed from the highest setting
and put the vehicle’s transmission into the P (Park) gear position
(automatic transmission only) to continue to receive cool air from your
A/C system.
For maximum cooling performance:
• Automatic operation:
1. Press AUTO for full automatic operation.
2. Do not override A/C or (recirculated air).
3. Set the temperature to 60°F (16°C).
• Manual operation:
1. Select MAX A/C. The system will automatically default to single zone
operation and set the temperature to 60°F (16°C).
• A/C and
(recirculated air) will be selected.
• Airflow will be directed out of the panel vents.
2. Fan speed will be automatically increased to the highest setting but
can be adjusted as desired.
To aid in side window defogging/demisting in cold weather:
1. Select (panel/floor).
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
REAR WINDOW DEFROSTER (IF EQUIPPED) R
The rear defroster control is located on the climate control panel and
works to defrost your rear window from fog and thin ice. If equipped, it
also operates the heated mirror to remove snow and thin ice from the
side mirrors.
