tow FORD FLEX 2019 Service Manual

Payload is the combined weight
of cargo and passengers that your
vehicle is carrying. The maximum
payload for your vehicle appears
on the Tire and Loading label. The
label is either on the B-pillar or the
edge of the driver door. Vehicles
exported outside the US and
Canada may not have a tire and
loading label. Look for
“The
combined weight of occupants
and cargo should never exceed
XXX kg OR XXX lb ” for maximum
payload. The payload listed on the
Tire and Loading Information label
is the maximum payload for your
vehicle as built by the assembly
plant. If you install any additional
equipment on your vehicle, you
must determine the new payload.
Subtract the weight of the
equipment from the payload listed
on the Tire and Loading label.
When towing, trailer tongue
weight or king pin weight is also
part of payload. WARNING: The appropriate
loading capacity of your vehicle
can be limited either by volume
capacity (how much space is
available) or by payload capacity
(how much weight the vehicle
should carry). Once you have
reached the maximum payload of
your vehicle, do not add more
cargo, even if there is space
available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover. GAWR (Gross Axle Weight
Rating)
GAWR is the maximum allowable
weight that a single axle (front or
rear) can carry. These numbers
are on the Safety Compliance
Certification label. The label is
located on the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver seating position.
The total load on each axle must
never exceed its Gross Axle
Weight Rating.
GVWR (Gross Vehicle Weight
Rating)
GVWR is the maximum allowable
weight of the fully loaded vehicle.
This includes all options,
equipment, passengers and cargo.
It appears on the Safety
Compliance Certification label.
The label is located on the door
hinge pillar, door-latch post, or the
door edge that meets the
door-latch post, next to the driver
seating position.
The gross vehicle weight must
never exceed the Gross Vehicle
Weight Rating.

Safety Compliance Certification Label
Example:
WARNING: Exceeding the
Safety Compliance Certification
label vehicle weight limits can
adversely affect the performance
and handling of your vehicle,
cause vehicle damage and can
result in the loss of control of your
vehicle, serious personal injury or
death.
Maximum Loaded Trailer
Weight
Maximum loaded trailer weight is
the highest possible weight of a
fully loaded trailer the vehicle can
tow. Consult an authorized dealer
(or the RV and Trailer Towing
Guide available at an authorized
dealer) for more detailed
information.
GCWR (Gross Combined
Weight Rating)
GCWR is the maximum allowable
weight of the vehicle and the
loaded trailer, including all cargo
and passengers, that the vehicle
can handle without risking
damage. (Important: The towing vehicle
’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note: For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNING:
Do not exceed
the GVWR or the GAWR specified
on the certification label. WARNING:
Do not use
replacement tires with lower load
carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations.

WARNING: Exceeding any
vehicle weight rating can
adversely affect the performance
and handling of your vehicle,
cause vehicle damage and can
result in the loss of control of your
vehicle, serious personal injury or
death.
Steps for determining the
correct load limit:
1. Locate the statement "The combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle ’s placard.
2. Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3. Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lb.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1,400 lb. and there will
be five 150 lb. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.) 5.
Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
Helpful examples for calculating
the available amount of cargo
and luggage load capacity
Suppose your vehicle has a
1400-pound (635-kilogram) cargo
and luggage capacity. You decide
to go golfing. Is there enough load
capacity to carry you, four of your
friends and all the golf bags? You
and four friends average 220
pounds (99 kilograms) each and
the golf bags weigh approximately
30 pounds (13.5 kilograms) each.
The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100
- 150 = 150 pounds. Yes, you have
enough load capacity in your
vehicle to transport four friends
and your golf bags. In metric units,
the calculation would be: 635
kilograms - (5 x 99 kilograms) -
(5 x 13.5 kilograms) = 635 - 495 -
67.5 = 72.5 kilograms.

TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR specified
on the certification label. WARNING:
Towing trailers
beyond the maximum
recommended gross trailer weight
exceeds the limit of your vehicle
and could result in engine
damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and
personal injury.
Note: Your vehicle may have
electrical items, such as fuses or
relays, related to towing. See
Fuses
(page 232).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See
Load Limit (page
202).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

TRAILER SWAY CONTROL (If
Equipped) WARNING:
Turning off trailer sway
control increases the risk of loss of vehicle
control, serious injury or death. Ford does
not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages
(page 103). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
202).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 20 ft² (1.86 m²) if
your vehicle can tow a class I
trailer, or 40 ft² (3.72 m²) if your
vehicle can tow a class III trailer.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per
1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Check
state regulations for this specified
weight. The maximum trailer
weights listed may be limited to
this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector
needed to use electric trailer
brakes.

* For towing trailers up to 3500 lb (1588 kg), use a weight-carrying hitch
and ball, which uniformly spreads the trailer tongue loads through your
vehicle ’s underbody structure. For towing trailers over 3500 lb (1588
kg), up to 4500 lb (2042 kg), we recommend you use a
weight-distributing hitch to increase front axle load while towing.
** For towing trailers up to 4500 lb (2042 kg), use a weight-carrying hitch
and ball, which uniformly spreads the trailer tongue loads through your
vehicle's underbody structure.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer.
See Scheduled
Maintenance (page 442).
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's
load in the Load Carrying chapter. See
Load Limit
(page 202).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight. Trailer Towing Connector
(Vehicles with a Trailer Towing
Package and 7
–Pin Connector) When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle.

Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
Weight-Distributing Hitch
WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper is
higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may cause
unpredictable handling, and could result
in serious personal injury.
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park your vehicle, without the trailer, on a level surface.
2. Measure the height of the top of your vehicle ’s front wheel opening on the
fender. This is H1.
3. Attach the trailer to your vehicle without the weight-distributing bars
connected.
4. Measure the height of the top of your vehicle ’s front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight distributing bars so that the
height of the front fender is
approximately halfway between H1 and
H2.
6. Check that the trailer is level. If not level, adjust the ball height accordingly
and repeat Steps 3–6.
Safety Chains
Note: Never attach safety chains to the
bumper. Always connect the safety chains to the
hook retainers of your vehicle hitch.
To connect the safety chains, cross them
under the trailer tongue and allow enough
slack for turning tight corners. Do not allow
the chains to drag on the ground.
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 lb (680 kg) when loaded.
Trailer Brake Controller Connector
(If Equipped)
The connector is located under the
instrument panel above the brake pedal.

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, turn signals 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 A/C
performance.
• Turn 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.
213
Flex (TP3) , enUSA, Edition date: 201803, Second-Printing TowingE211392

2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
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.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Any time the rear axle submerges in water,
replace the rear axle lubricant. Water may
contaminate the rear axle lubricant, which
is not a normal maintenance inspection
item unless there is a possibility of a leak
or other axle repair is required. TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies or vehicle
transport trailer), it can be flat-towed (all
wheels on the ground, regardless of the
powertrain and transmission
configuration) under the following
conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Shift into neutral (N). If you cannot
shift into neutral (N), you may need to
override it.
See Transmission (page
162).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering the vehicle. See
Climate Control
(page 112).
Follow these guidelines if you have a need
for recreational (RV) towing. An example
of recreational towing would be towing
your vehicle behind a motorhome. We
designed these guidelines to prevent
damage to your transmission.
You can tow your vehicle with all four
wheels on the ground.
If you tow your vehicle with all four wheels
on the ground:
• Tow only in the forward direction.
• Release the parking brake.
Vehicles with Keyless Start
1. Start the vehicle by pressing the brake pedal, and then pressing the keyless
start button until the vehicle starts.
