tires FORD E SERIES 2011 4.G Service Manual

WARNING:Exceeding any vehicle weight rating limitation could
result in serious damage to the vehicle and/or personal injury.
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.). In metric units (635-340 (5 x 68) = 295 kg.)
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.
The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
•Another example for your vehicle with 1,400 lb. (635 kg) of cargo and
luggage capacity. You decide to go golfing. Is there enough load
capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100 - 150 = 150 lb. 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 kg - (5 x
99 kg) - (5 x 13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.
•A final example for your vehicle with 1,400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for
12-100 lb. (45 kg) bags of cement. Do you have enough load capacity
to transport the cement to your home? If you and your friend each
weigh 220 lb. (99 kg), the calculation would be: 1400 - (2 x 220) - (12

x 100) = 1400 - 440 - 1200 = - 240 lb. No, you do not have enough
cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least
240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then
the load calculation would be:
1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have
the load capacity to transport the cement and your friend home. In
metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x
45 kg) = 635 - 198 - 405 = 32 kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.
Special loading instructions for owners of pick-up trucks and
utility-type vehicles
WARNING:For important information regarding safe operation
of this type of vehicle, see thePreparing to drive your vehicle
section in theDrivingchapter of this owner’s guide.
WARNING:Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a heavily
loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer, provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Do not exceed trailer weight of 5,000 lb (2,268 kg) when towing with
bumper only.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10–15% of the total is on the tongue. Tie
down the load so that it does not shift and change the weight on the hitch.

– Maximum trailer weight for all cutaway vehicles must be calculated
by subtracting the weight of the vehicle (including incomplete vehicle
weight and payload which includes second unit body weight, cargo and
passengers) from the GCW; otherwise, maximum trailer weight is
10000 lb (4536 kg).
– For high altitude operation reduce GCWR by 2% per 1000 ft (300 m)
elevation.
– To determine the maximum trailer weight designed for your
particular vehicle as equipped, follow the sectionVehicle loading -
with and without a trailerearlier in this chapter.

WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.
Hitches
Do not use or install hitches that clamp onto the bumper or to the axle.
Underbody hitches are acceptable if installed properly.
Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one inch (25.4 mm) shank diameter. The bumper has a
5,000 lb (2,270 kg) trailer weight and 500 lb (227 kg) tongue weight
capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
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.
Tires, Wheels and Loading

The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Integrated trailer brake controller (if equipped)
Your vehicle may be equipped with a fully integrated electronic Trailer
Brake Controller (TBC). When used properly, the TBC helps ensure
smooth and effective trailer braking by powering the trailer’s electric
brakes with a proportional output based on the towing vehicle’s brake
pressure.
WARNING:The Ford TBC has only been verified to be
compatible with trailers having electric-actuated drum brakes
(one to four axles) and not hydraulic surge or electric-over-hydraulic
types. It is the responsibility of the customer to ensure that the trailer
brakes are adjusted appropriately, functioning normally and all electric
connections are properly made.
The TBC user interface consists of
the following:
1.+/- (GAIN adjustment
buttons):Pressing these buttons
will adjust the TBC’s power output
to the trailer brakes (in
0.5 increments). The GAIN setting
can be increased to a maximum of
10.0 or decreased to a minimum of 0 (no trailer braking). Pressing and
holding a button will raise or lower the setting continuously. The gain
setting will display in the message center as follows: TBC GAIN = XX.X.
The trailer brake controller (TBC) is designed to display three items of
information in the instrument cluster message center. These are: gain
setting, output bar graph, and trailer connectivity status. They will
appear as follows in the message center.
•TBC GAIN = XX.X NO TRAILER: The instrument cluster message
center will display the current gain setting during a given ignition
cycle and when adjusting the gain. This message is also displayed
during manual activation without a trailer connected or when gain
adjustments are made with no trailer connected.
Tires, Wheels and Loading

2011 Econoline(eco)
Owners Guide, 1st Printing
USA(fus)

•TBC GAIN = XX.X OUTPUT = //////: When the vehicle’s brake pedal
is pushed, or when the manual control is activated, bar indicators will
illuminate in the instrument cluster message center to indicate the
amount of power going to the trailer brakes relative to the brake pedal
or manual control input. One bar indicates the least amount of output
with six bars indicating maximum output.
•TRAILER CONNECTED:This message is displayed when a correct
trailer wiring connection (a trailer with electric trailer brakes) has
been sensed during a given ignition cycle.
•TRAILER DISCONNECTED:This message is displayed and
accompanied by a single chime, when a trailer connection was
determined and then a disconnection, either intentionally or
unintentionally, has been sensed during a given ignition cycle. It is also
displayed if a truck or trailer wiring fault occurs causing the trailer to
appear disconnected. This message is also displayed during manual
activation without a trailer connected.
2.Manual control lever:Slide the control lever to the left to activate
power to the trailer’s electric brakes independent of the tow vehicle’s
brakes (see the followingProcedure for adjusting GAINsection for
instructions on proper use of this feature). If the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
•Stop Lamps:Activating the TBC manual control lever will illuminate
both the trailer brake lamps and the tow vehicle brake lamps except
the Center High-Mount Stop Lamp (presuming proper trailer electrical
connection). Pressing the vehicle brake pedal will also illuminate both
trailer and vehicle brake lamps.
Procedure for adjusting GAIN:
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle load, road conditions
and weather.
The GAIN should be set to provide the maximum trailer braking
assistance while ensuring the trailer wheels do not lock when braking.
Locked trailer wheels may lead to trailer instability.
Note:This should only be performed in a traffic free environment at
speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working condition,
functioning normally, and properly adjusted. See your trailer dealer if
necessary.
Tires, Wheels and Loading

2. Hook up the trailer and make the electrical connections according to
the trailer manufacturer’s instructions.
3. When a trailer with electric brakes is plugged in, theTRAILER
CONNECTEDmessage will display in the instrument cluster message
center.
4. Use the GAIN adjustment (+/-) buttons to increase or decrease the
GAIN setting to the desired starting point. A GAIN setting of 6.0 is a
good starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at
a speed of 20–25 mph (30–40 km/h) and squeeze the manual control
lever completely.
6. If the trailer wheels lock-up (indicated by squealing tires), reduce the
GAIN setting; if the trailer wheels turn freely, increase the GAIN setting.
Repeat Steps 5 and 6 until the GAIN setting is at a point just below
trailer wheel lock-up. If towing a heavier trailer, trailer wheel lockup may
not be attainable even with the maximum GAIN setting of 10.
Explanation of instrument cluster warning messages:
The TBC interacts with the instrument cluster message center to display
the following messages:
TRAILER BRAKE MODULE FAULT: This message is displayed and
accompanied by a single chime, in response to faults sensed by the TBC.
In the event this message is seen, please contact your authorized dealer
as soon as possible for diagnosis and repair. The TBC may still function,
but performance may be degraded.
WIRING FAULT ON TRAILER: This message is displayed when a
Short circuit on the electric brake output wirehas occurred. If the
WIRING FAULT ON TRAILERmessage is displayed and accompanied
by a single chime, with no trailer connected, the problem is with the
vehicle wiring from the TBC to the 7–pin connector in the bumper. If the
message is only displayed with a trailer connected, the problem is related
to the trailer wiring; consult your trailer dealer for assistance. This can
be a short to ground (i.e., chaffed wire) or a short to voltage (i.e., pulled
pin on trailer emergency break-away battery) or trailer brakes drawing
too much current.
Note:Your TBC can be diagnosed by your authorized dealer to
determine exactly which trailer fault has occurred; however, if the fault
is with the trailer this diagnosis isnotcovered under your Ford
warranty.

Points to Remember:
•Remember to adjust gain setting before using the TBC for the first
time.
•Readjust GAIN setting on the TBC (according to procedure above)
whenever road, weather and trailer or vehicle loading conditions
change from those that existed when the gain was initially set.
•The sliding lever on the TBC should be used only for manual
activation of trailer brakes to assist with proper adjustment of the
GAIN. Misuse, such as application during trailer sway, could cause
instability of trailer and/or tow vehicle.
•Avoid towing in adverse weather conditions. The TBC does not
provide anti-lock control of the trailer wheels. Trailer wheels can
lock-up on slippery surfaces, resulting in reduced stability of trailer
and tow vehicle.
•The TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lockup.
Therefore, if these systems are not functioning properly the TBC may
not function at full performance.
•When the vehicle is turned off, the TBC Output is disabled and the
display is shut down. Turning the ignition from off to on will awaken
the TBC module.
•The TBC is only a factory or dealer installed item. Ford is not
responsible for warranty or performance of the TBC due to misuse or
customer installation.
•Do not attempt removal of the TBC without consulting the
Workshop Manual.Damage to the unit may result.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking-up trailer lamps.
Driving while you tow
When towing a trailer:
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
