2003 FORD E SERIES AUX

•Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to“breathe”using the outside air inlet vents.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
To aid in side window defogging/demisting in cold weather:
1. Select
2. Select A/C
3. Modulate the temperature control to maintain comfort.
4. Set the fan speed to HI
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.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.
AUXILIARY SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with
auxiliary climate controls which
allow you to control the airflow level
in the rear of the vehicle. The front
controls will still control the
temperature setting.
To allow the rear passengers to
control the fan speed, the front
auxiliary unit must be turned to the
REAR CTRL position.
Once the front auxiliary control is
set to REAR CTRL, the rear
passengers may select the fan speed
from the rear auxiliary unit located
in the overhead between the second
and third row seating.

•Drive the vehicle slowly (less than 5 km/h [3 mph]) in circles until
CAL indicator turns off in about 2–3 complete circles.

CELL PHONE USE
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
driver’s must not compromise their own or other’s safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.
AUXILIARY POWER POINT
Power outlets are designed for
accessory plugs only. Do not
hang any type of accessory or
accessory bracket from the plug.
Improper use of the power
outlet can cause damage not
covered by your warranty.
The auxiliary power point is located
on the instrument panel.
A second power point (if equipped)
is located behind the driver’s seat on the upper trim panel.
Do not plug optional electrical accessories into the cigarette
lighter. Use the power point.
