2013 FORD F250 brakes

Driving on hilly or sloping terrain
Note:Avoid driving crosswise or turning on steep slopes or hills.
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. . A danger lies in losing traction, slipping sideways and
possibly rolling 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 you do stall out, do not try to turn around because you might roll over.
It is better to back down 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; instead, disengage overdrive
or manually shift to a lower gear.
When descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
they aren’t turning, you won’t be able
to steer. The front wheels have to be turning in order to steer the 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 the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
4WD vehicles have advantages over 2WD 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 as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, 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 brakes. Refer to theBrakessection of this chapter for additional
information on the operation of the Anti-lock Brake System (ABS).

Parking
WARNING: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.
WARNING: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.
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. 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.
Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor Company
strongly recommends that you do not make modifications such as adding or
removing parts (such as lift kits or stabilizer bars) or by using replacement
parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

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 and should be inspected by an authorized dealer. If your
vehicle has continuous vibration or shudder in the steering wheel while
braking, you should take it to an authorized dealer for inspection.
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 theVehicle Carechapter for wheel
cleaning instructions.
See theInstrument Clusterchapter for information on the
brake system warning light.
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 your vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to
positionPand apply the parking brake, then inspect the accelerator
pedal for any interferences. 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 heavily by measuring the rate at
which you press the brake pedal. It provides maximum braking efficiency
as long as you press the pedal. Brake assist 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.
The anti-lock brake system lamp momentarily illuminates when
the ignition is turned on. If the light does not illuminate during
start-up, remains on or flashes, the anti-lock brake system may
be disabled and may need to be serviced.

If the anti-lock brake system is disabled, normal braking is still
effective. If the brake warning lamp illuminates with the parking
brake released, have your brake system serviced immediately.
HINTS ON DRIVING WITH ANTI-LOCK BRAKES
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 dangers inherent
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 that
the transmission selector lever is securely latched in positionP.
To set the parking brake, press the parking brake pedal down until the
pedal stops.
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.

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
(Dual rear wheel vehicles only)
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power.
Turn the traction control system off by pressing the
stability control button located on the instrument
panel.
If the system cannot be turned off, see theMyKeychapter for more
information.
If traction control is on when your vehicle is put into four-wheel drive
mode (if equipped), the traction control system will be automatically
disabled. Traction control operation will resume when your vehicle is
placed back into two-wheel drive mode.

Hill descent control (if equipped)
Hill descent control allows the driver to set and maintain vehicle speed
while descending steep grades in various surface conditions.
WARNING:Hill descent control cannot control descent in all
surface conditions and circumstances, such as ice or extremely
steep grades. Hill descent control is a driver assist system and cannot
substitute for good judgment by the driver. Failure to do so may result
in loss of vehicle control, crash or serious injury.
Hill descent control can maintain vehicle speeds on downhill grades
between 2 mph (3 km/h) and 12 mph (20 km/h). Above 20 mph
(32 km/h), the system remains armed, but descent speed cannot
be set or maintained.
WARNING:Hill descent control does not provide hill hold at
zero mph (0 km/h). When stopped, the parking brake must be
applied and/or the vehicle must be placed in P (Park) or it may roll
away.
Hill descent control requires a cooling down interval after a period of
sustained use. The amount of time that the feature can remain active
before cooling varies with conditions. The system will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system;
this may include reduced performance or a false activation.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note:Keep the sensors (located on the bumper/fascia) free from snow,
ice and large accumulations of dirt. If the sensors are covered, the
system’s accuracy can be affected. Do not clean the sensors with sharp
objects.
Note:If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note:If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to theMyKey®chapter.
Note:If your vehicle is equipped with a fully integrated electronic
trailer brake controller (TBC) and a trailer with electric trailer brakes is
connected to your vehicle, the RSS will be disabled. When the vehicle is
shifted into reverse, the message center display will remain in the Rear
Park Aid Off selection. For more information on the TBC, refer to the
Towingchapter.
