SAFETY AND ENVIRONMENT PROTECTION
Warning symbols in this guide
How can you reduce the risk of personal injury and prevent possible
damage to others, your vehicle and its equipment? In this guide, answers
to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed.
Warning symbols on your vehicle
When you see this symbol, it is
imperative that you consult the
relevant section of this guide before
touching or attempting adjustment
of any kind.
Protecting the environment
We must all play our part in
protecting the environment. Correct
vehicle usage and the authorized
disposal of waste cleaning and
lubrication materials are significant
steps towards this aim. Information in this respect is highlighted in this
guide with the tree symbol.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,600 km (1,000 miles) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle for at least 800 km (500 miles) before towing a
trailer or snowplowing.
Do not add friction modifier compounds or special break-in oils during
the first few thousand kilometers (miles) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and specificationschapter for more information on oil
usage.

Transmission fluid temperature gauge (automatic transmission
only):If the gauge is in the:
White area(normal) - the
transmission fluid is within the
normal operating temperature
(between“H”and“C”).
Yellow area(warning)—the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
scheduled maintenance guide for
instructions. Operating the
transmission for extended periods of
time with the gauge in the yellow
area may cause internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area(over temperature)—
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the Yellow or Red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your Ford dealer.

RADIO FREQUENCIES
AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz
RADIO RECEPTION FACTORS
There are three factors that can affect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CASSETTE/PLAYER CARE
Do:
•Use only cassettes that are 90 minutes long or less.
•Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
•Remove loose labels before inserting tapes.

To aid in side window defogging/demisting in cold weather:
1. Select
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. 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.
MANUAL HEATING AND AIR
CONDITIONING SYSTEM
1.Fan speed adjustment:Controls
the volume of air circulated in the
vehicle.
2.Temperature selection:
Controls the temperature of the airflow in the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Uses recirculated air to cool the vehicle. Air flows from the
instrument panel vents only.
A/C:Uses outside air to cool the vehicle. Air flows from the instrument
panel vents only.
:Distributes outside air through the instrument panel vents.
OFF:Outside air is shut out and the fan will not operate.
:Distributes outside air through the instrument panel vents and the
floor vents.
:Distributes outside air through the floor vents.
:Distributes outside air through the windshield defroster vents and
floor vents.
:Distributes outside air through the windshield defroster vents.

Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
air flow selector in the OFF or MAX A/C position.
•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.

Foglamp control (if equipped)
The headlamp control also operates
the foglamps. The foglamps can be
turned on only when the headlamp
control is in the
,or
position and the high beams are not
turned on.
In autolamp mode, the foglamps
won’t be operational until lighting
conditions warrant the activation of the headlamp/parklamp lighting.
Pull headlamp control towards you to turn foglamps on. The foglamp
indicator light
will illuminate when the switch is pulled and the
parklamps are on.
Daytime running lamps (DRL) (if equipped)
Turns the headlamps on with a reduced output.
To activate:
•the ignition must be in the ON position and
•the headlamp control is in the OFF, parking lamp or autolamp
position.
Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Lamp (DRL) system
does not activate with your tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.
