2016 FORD F250 warning

USING FOUR-WHEEL DRIVE
WARNING
For important information regarding
safe operation of this type of vehicle,
See General Information (page
264). Note:
Do not use 4X4 mode on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces.
Note: If 4X4 low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to/from 4L (4X4
Low) for proper operation.
Manual Shift On Stop (MSOS)
4WD system
(If Equipped)
Note: Some vehicles may be equipped with
wheel ornaments that cover the 4x4 manual
hub lock. These ornaments must be
removed to access the manual hub locks.
Note: The vehicle should not be driven in
4X4 High or 4X4 Low modes with the hub
locks set to FREE as this condition may
damage driveline system components. The 4WD system is engaged or disengaged
by rotating the control for both front wheel
hub locks from the FREE or LOCK position,
then manually engaging or disengaging the
transfer case with the floor-mounted
shifter. For increased fuel economy in 2WD,
rotate both hub locks to the FREE position.
Electronic Shift-On-the-Fly
(ESOF) 4WD system
Note:
If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to/from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually overridden by rotating the hub lock
control from AUTO to LOCK. For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to LOCK or both set to AUTO). To
engage LOCK, turn the hub locks
completely clockwise; to engage AUTO,
turn the hub locks completely
counterclockwise.

authorized dealer.
4X2 Momentarily illuminates when
2H is selected.
4X4 HIGH Continuously illuminates when
4H is selected.
4X4 LOW Continuously illuminates when
4L is selected.
CHECK 4X4 Displays when a 4X4 fault is
present. Using a Manual Shift On Stop
(MSOS) 4WD system (If Equipped)
Note: High shift efforts may be encountered
when attempting to shift into and out of 4x4
modes. It is recommended to allow the
vehicle to roll at a speed below
3 mph
(5 km/h) when shifting between modes. 2H (2WD)
For general on-road driving. Sends power
to the rear wheels only and should be used
for street and highway driving. Provides
optimal smoothness and fuel economy at
high speeds
4H (4x4 High)

Shifting between system modes
Note:
Do not perform these operations if
the rear wheels are slipping.
Note: Some noise may be heard as the 4x4
system shifts or engages. This is normal. In
order to reduce engagement noise, it is
recommended that all shifts be performed
at speeds below3 mph (5 km/h).
Note: The vehicle should not be driven in
4X4 High with the hub locks disengaged as
this condition may damage driveline system
components.
Engage the locking hubs by rotating the
hub lock control from FREE to LOCK, then
move the transfer case lever from 2H
(2WD) to 4H (4x4 High) at a stop or a
vehicle speed below
3 mph (5 km/h).
Move the transfer case lever from 4H (4x4
High) to 2H (2WD) at a stop or a vehicle
speed below
3 mph (5 km/h), then
disengage the locking hubs (optional) by
rotating the hub lock control from LOCK
to FREE.
For proper operation, make sure that both
indicator arrows on the hub are aligned,
and that both hubs are set to either FREE
or LOCK.
Shifting to/from 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below
3 mph (5 km/h).
2. Place the transmission in N (Neutral).
3. Move the transfer case shift lever through N (Neutral) directly to the
desired position.
4. If the transfer case does not, or only partially moves to the desired position,
perform a shift with the transmission
in N (Neutral) and the vehicle rolling at
a speed below
3 mph (5 km/h). 5.
If shifting to 2H (2WD) with the vehicle
at a complete stop, disengage the
locking hubs (optional) by rotating the
hub lock control from LOCK to FREE.
Using the N (Neutral) position WARNING
Do not leave the vehicle unattended
with the transfer case in the N
(Neutral) position. Always set the
parking brake fully and turn off the ignition
when leaving the vehicle. The transfer case neutral position overrides
the transmission and puts the vehicle in
neutral regardless of transmission gearshift
lever position. The vehicle can move
forward or backwards.
This position should only be used when
towing the vehicle.

If SHIFT DELAYED PULL FORWARD is
displayed in the information display,
transfer case gear tooth blockage is
present. To alleviate this condition, place
the transmission in a forward gear, move
the vehicle forward approximately
5 ft
(1.5 m), and shift the transmission back to
neutral to allow the transfer case to
complete the range shift.
How Your Vehicle Differs From
Other Vehicles WARNING
Vehicles with a higher center of
gravity such as utility and four-wheel
drive vehicles handle differently than
vehicles with a lower center of gravity.
Utility and four-wheel drive vehicles are
not designed for cornering at speeds as
high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these
vehicles. Failure to drive cautiously could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing two bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.

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 169).
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. 165

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy
Wheels (page 261). See
Warning Lamps and
Indicators (page 84).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations. Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the anti-lock brake system is
disabled, normal braking is still effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal will pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.

PARKING BRAKE
WARNING
Always set the parking brake fully
and make sure the transmission is
placed in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. Turn the ignition to the lock
position and remove the key whenever you
leave your vehicle. Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release, pull the brake release lever
located at the lower left side of the
instrument panel.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake. Failure to leave your vehicle securely
parked may lead to a crash or injury. See
Parking Brake (page 170). WARNINGS
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. The system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to
take care may result in the loss of control
of your vehicle, serious personal injury or
death. The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient drive to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
Note:
The system only functions when you
bring your vehicle to a complete standstill
in an uphill gear (for example, drive when
facing uphill or reverse when facing
downhill).
Note: There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed.
