2014 FORD F250 light

Tow/haul delays upshifts to reduce
frequency of transmission shifting.
Tow/haul also provides engine braking in
all forward gears when the transmission is
in the D (Overdrive) position; this engine
braking will slow the vehicle and assist the
driver in controlling the vehicle when
descending a grade. Depending on driving
conditions and load conditions, the
transmission may downshift, slow the
vehicle and control the vehicle speed when
descending a hill, without the accelerator
pedal being pressed. The amount of
downshift braking provided will vary based
upon the amount the brake pedal is
pressed.
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the end of the gearshift lever.
The TOW HAUL light will no longer be
illuminated.
When you shut-off and restart the engine,
the transmission will automatically return
to normal D (Overdrive) mode (tow/haul
off).
WARNING
Do not use the tow/haul feature
when driving in icy or slippery
conditions as the increased engine
braking can cause the rear wheels to slide
and the vehicle to swing around with the
possible loss of vehicle control. 3 (Third)
Transmission starts and operates in third
gear only
Used for improved traction on slippery
roads. Selecting 3 (Third) provides engine
braking.
2 (Second)
Use 2 (Second) to start-up on slippery
roads or to provide additional engine
braking on downgrades. 1 (First)
•
Provides maximum engine braking
• Allows upshifts by moving gearshift
lever
• The transmission will not downshift
into 1 (First) at high speeds; it will
downshift to a lower gear and then
shift into 1 (First) when the vehicle
reaches slower speeds.
Forced downshifts
• Allowed in D (Overdrive) with the
tow/haul feature on or off
• Press the accelerator to the floor

With the gearshift lever in N (Neutral), the
vehicle can be started and is free to roll.
Hold the brake pedal down while in this
position.
D (Overdrive) with tow/haul off
D (Overdrive) with tow/haul off is the
normal driving position for the best fuel
economy. The overdrive function allows
automatic upshifts and downshifts through
gears one through six.
D (Overdrive) with tow/haul on
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
To activate tow/haul, press the
button on the end of the
gearshift lever. The TOW HAUL
indicator light will illuminate in the
instrument cluster. Tow/haul delays upshifts to reduce
frequency of transmission shifting.

9. Start the vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as the halves are rotated
together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
POWER TAKE-OFF
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation. Ford Super Duty Vehicles are approved for
use as a stationary (including split shaft
capability) or mobile power source, within
limits and operating guidelines detailed in
the Ford Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas,
and through the Ford Truck Body Builders
Advisory Service.

Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal while moving slowly.
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should always
try to drive straight up or straight down. Note:
Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn
around because this could cause vehicle
roll over. It is better to reverse back to a
safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control. Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral. Disengage
overdrive or move the transmission
selector lever to a lower gear. When
descending a steep hill, avoid sudden hard
braking as you could lose control. The front
wheels have to be turning in order to steer
your vehicle.
155
Super Duty (TFA) Four-Wheel Drive (If Equipped)E143949

If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.
Driving on Snow and Ice
WARNING
If you are driving in slippery
conditions that require tire chains or
cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
your vehicle slides while cornering, steer in
the direction of the slide until you regain
control of your vehicle. Note:
Excessive tire slippage can cause
transmission damage.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it will not stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions. Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Hints on Driving With
Anti-Lock Brakes (page 160).
If Your Vehicle Gets Stuck In Mud or
Snow WARNING
Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNINGS
If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Always set the parking brake fully
and make sure the gearshift is
latched in P (Park). Turn the ignition
to the off position and remove the key
whenever you leave your vehicle. 156

LIMITED SLIP DIFFERENTIAL
This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
ELECTRONIC LOCKING
DIFFERENTIAL
Note:
The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration.
The electronic locking differential is a
device housed in the rear axle that allows
both rear wheels to turn at the same
speed. The electronic locking differential
can provide additional traction should your
vehicle become stuck. You can activate
the differential electronically and shift it
on the fly within the differential operating
speed range. The differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction. It is
not for use on dry pavement.
The following conditions will affect the
electronic locking differential: •
On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will not engage if the vehicle speed is
above 20 mph (32 km/h).
• On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will automatically disengage at speeds
above 25 mph (40 km/h) and will
automatically reengage at speeds
below 20 mph (32 km/h).
• On 4WD vehicles in 4L (4X4 Low), the
ELD can be engaged at any speed and
will not automatically disengage.
Activating the Electronic Locking
Differential (If Equipped)
Note: Do not use electronic locking
differential on dry, hard surfaced roads.
Doing so will produce excessive noise,
vibration and increase tire wear.
Note: If the electronic locking differential
has difficulty disengaging, release the
accelerator pedal and turn the steering
wheel in the opposite direction while rolling.
For vehicles equipped with an
electronic shift 4WD system Pull the 4WD control knob toward you.

For 2WD vehicles and vehicles
equipped with a manual shift 4WD
system
Turn the control to ON.
Once the indicator light
illuminates in the information
display, both rear wheel axle
shafts will be locked together providing
added traction.
If the indicator does not come on, or the
indicator turns off while driving, one of the
following has occurred:
• The vehicle speed is too high.
• The left and right rear wheel speed
difference is too high during an
engagement attempt.
• The system has malfunctioned and is
accompanied by CHECK LOCKING
DIFFERENTIAL in the information
display. See your authorized Ford
dealer for assistance.
