2017 FORD F53 air conditioning

ABOUT THIS MANUAL
Thank you for choosing Ford. We
recommend that you take some time to
get to know your vehicle by reading this
manual. The more that you know about
your vehicle, the greater the safety and
pleasure you will get from driving it.
WARNING
Driving while distracted can result in
loss of vehicle control, crash and
injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the safe
operation of your vehicle. We recommend
against the use of any hand-held device
while driving and encourage the use of
voice-operated systems when possible.
Make sure you are aware of all applicable
local laws that may affect the use of
electronic devices while driving. Note:
This manual describes product
features and options available throughout
the range of available models, sometimes
even before they are generally available. It
may describe options not fitted to the
vehicle you have purchased.
Note: Some of the illustrations in this
manual may show features as used in
different models, so may appear different
to you on your vehicle.
Note: Always use and operate your vehicle
in line with all applicable laws and
regulations.
Note: Pass on this manual when selling
your vehicle. It is an integral part of your
vehicle. Note:
Either Ford Motor Company or an
authorized Ford dealer may have originally
sold this incomplete vehicle to a vehicle
modifier who upfitted it. As a result, it may
have different options and features than
described in this manual.
This manual may qualify the location of a
component as left-hand side or right-hand
side. The side is determined when facing
forward in the seat. Right-hand side.

Trailer Brakes
WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 pounds (680 kilograms)
when loaded.
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 lights, brake
lights, direction indicators and hazard lights
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) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your 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 park (P) to aid engine and
transmission cooling and to help air
conditioning performance.
• Switch off the speed control with
heavy loads or in 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 your transmission is equipped with a
Grade Assist or 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.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.

BREAKING-IN
You need to break in new tires for
approximately 300 miles (480
kilometers). During this time, your vehicle
may exhibit some unusual driving
characteristics.
Avoid driving too fast during the first 1000
miles (1600 kilometers). Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Do not tow during the first 1000 miles
(1600 kilometers).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase the
engine temperature and cause the
engine to shut down completely.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 14).
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 will continue to operate
with limited power for a short time.
If the engine temperature continues to rise,
the fuel supply to the engine will reduce.
The air conditioning will switch off and the
engine cooling fan will operate continually.
1. Reduce your speed gradually and stop
your vehicle as soon as it is safe to do
so.
2. Switch the engine off immediately to prevent severe engine damage.
3. Wait for the engine to cool down. 4. Check the coolant level. See
Engine
Coolant Check (page 89).
5. Have your vehicle checked by an authorized dealer as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.

F53 Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. Locate the power distribution box in the
engine compartment. It has high-current
fuses that protect your vehicle's main
electrical systems from overloads.
If the battery has been disconnected and
reconnected, you will need to reset some
features. See Changing the 12V Battery
(page 98).
