ac Control FORD TRANSIT 2021 Owners Manual

•
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.

•
If your vehicle is fitted with
AdvanceTrac with roll stability control
(RSC), this system may turn on during
typical cornering maneuvers with a
heavily loaded trailer. This is normal.
Turning the corner at a slower speed
while towing may reduce this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your vehicle's rear axle with
synthetic gear lubricant (if the axle is
not already filled with it). See
Capacities and Specifications (page
352).
• 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:
•Turn the steering wheel to point
your vehicle tires away from traffic
flow.
• Set your vehicle parking brake.
• Place the automatic transmission
in position park (
P).
• Place wheel chocks in front of and
at the back of the trailer wheels.
(Trailer wheel chocks are not
included with your vehicle.)
Launching or Retrieving a Boat or
Personal Water Craft (PWC)
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Note: Disconnect the wiring to the trailer
before backing the trailer into the water. Note:
Reconnect the wiring to the trailer
after the trailer is removed from the water.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
If you need to tow your vehicle, contact a
professional towing service or, if you are a
member of a roadside assistance program,
your roadside assistance service provider.

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)
.

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics. The engine
also needs to break in. Avoid hard
accelerations and driving too fast for the
first 1,000 mi (1,600 km). If possible, avoid
carrying heavy loads up steep grades
during the break-in period.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so: •
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNING:
Use a floor mat
designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury. WARNING:
Secure the floor mat
to both retention devices so that it
cannot slip out of position and interfere
with the pedals. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING: Do not place additional
floor mats or any other covering on top
of the original floor mats. This could
result in the floor mat interfering with the
operation of the pedals. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Always make sure that
objects cannot fall into the driver foot
well while your vehicle is moving. Objects
that are loose can become trapped
under the pedals causing a loss of
vehicle control.
