HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Do not place objects under the front seats
as this may interfere with directing air to
the rear seats.
Remove any snow, ice or leaves from the
air intake area at the base of the
windshield.
Note:
You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.
Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on. Note:
To reduce fogging of the windshield
during humid weather conditions, direct air
to the windshield air vents.
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: Use air conditioning with recirculated
air to improve cooling performance and
efficiency.
Quickly Heating the Interior
• Select the highest blower motor speed.
• Select the highest temperature.
• Direct air to the footwell air vents.
Recommended Settings for
Heating
• Select a medium blower motor speed.
• Select the required temperature.
• Direct air to the footwell and
windshield air vents.
Quickly Cooling the Interior
• Select maximum cooling.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Recommended Settings for
Cooling
• Select a medium blower motor speed.
• Select the required temperature.
• Direct air to the instrument panel air
vents.

•
The trailer brake controller is fitted with
a feature that reduces output at vehicle
speeds below 11 mph (18 km/h) so
trailer and vehicle braking is not jerky
or harsh. This feature is only available
when applying the brakes using your
vehicle's brake pedal, not the
controller.
• The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.
• Your vehicle's brake system and the
trailer brake system work
independently of each other. Changing
the gain setting on the controller does
not affect the operation of your
vehicle's brake system whether you
attach a trailer or not.
• When you switch the engine off, the
controller output is disabled and the
display and module shut down. The
controller module and display turn on
when you switch the ignition on.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. Ford is not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Trailer Lamps WARNING:
Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required. Trailer lamps are required on most towed
vehicles. Make sure all running lamps,
brake lamps, turn signals and hazard
warning lamps are working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than
70 mph
(113 km/h) until you drive your vehicle
at least 495 mi (800 km). See
Breaking-In (page 247).
• Do not make full-throttle starts.
• Check the tow hitch, electrical
connections and trailer wheel lug nuts
thoroughly after you have traveled
50 mi (80 km)
.
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position park (
P) to aid
engine and transmission cooling and
to help A/C performance.
• Turn off the speed control with heavy
loads or on hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If the transmission is fitted with a
Grade Assist, Tow/Haul
feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 110).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 285).
5. Have your vehicle checked as soon as possible. ECONOMICAL DRIVING
The following helps to improve fuel
consumption:
•
Regularly check your tire pressures and
make sure that they are inflated to the
correct pressure.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Plan your journey and check the traffic
before you set off.
• Avoid idling the engine in cold weather
or for extended periods. Start the
engine only when you are ready to set
off.
• Do not carry unnecessary weight in your
vehicle as extra weight wastes fuel.
• Do not add unnecessary accessories
to the exterior of your vehicle, for
example running boards. If you use a
roof rack, remember to fold it down or
remove it when not in use.
• Drive smoothly, accelerate gently and
anticipate the road ahead to avoid
heavy braking.
• Switch off all electric systems when
not in use, for example air conditioning.
Make sure that you unplug any
accessories from the auxiliary power
points when not in use.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C)
.
