2011 FORD SUPER DUTY steering

Braking
•Anticipate the need to stop; allow much more distance and time to
stop than normal.
•Do not apply the trailer brakes for extended periods of time as they
can overheat and lose effectiveness.
•The trailer brakes must be inspected and serviced at intervals
specified by the manufacturer. This includes the shoes, drum and
trailer brake magnets.
•Electric brakes also require periodic adjustment to keep the shoes
properly spaced. If the brakes get hot when driving or if they will not
hold, chances are that they need adjustment.
Backing-up
•Practice backing-up, particularly if you are a novice. Turn the steering
wheel to the right to move the trailer’s rear end to the right.
•Sharp steering movements may cause the trailer to jackknife or go out
of control.
Tires
•Select tires that meet the trailer loading requirements.
•All trailer tires should be of the same size, and construction.
•Always check tow vehicle and trailer tire pressure before towing.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed 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.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.

STARTING
Positions of the ignition
1. Off— shuts off the engine and all
accessories/locks the steering wheel
and allows key removal.
2. Accessory— allows the electrical
accessories such as the radio to
operate while the engine is not
running. This position also unlocks
the steering wheel.
3. On— all electrical circuits
operational. Warning lights
illuminated. Key position when driving.
4. Start— cranks the engine. Release the key as soon as the engine
begins cranking.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.

3. Turn the key to 3 (on) without
turning the key to 4 (start).
Some warning lights will briefly illuminate. SeeWarning lights and
chimesin theInstrument Clusterchapter for more information
regarding the warning lights.
Starting the engine
1. Turn the key to 3 (on) without
turning the key to 4 (start). If there is
difficulty in turning the key, rotate the
steering wheel until the key turns
freely. This condition may occur when:
•the front wheels are turned.
•a front wheel is against the curb.
2. Turn the key to 4 (start), then
release the key as soon as the
engine begins cranking. Your vehicle has a computer assisted cranking
system that assists in starting the engine. After releasing the key from
the 4 (start) position, the engine may continue cranking for up to
10 seconds or until the vehicle starts.
Note:Cranking may be stopped at any time by turning the key to the off
position.
3. After idling for a few seconds, release the parking brake, apply the
brake, shift into gear and drive.
Note:If the engine does not start on the first try, turn the key to the off
position, wait 10 seconds and try Step 2 again. If the engine still fails to
start, press the accelerator to the floor and try Step 2 again, keeping the
accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.
Your vehicle may have remote start capability. Refer toRemote entry
systemin theLocks and Securitychapter.

BRAKES
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 the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toWarning lights and
chimesin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an anti-lock braking system (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.
Brake assist
The brake assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and uses the
ABS system to achieve maximum braking pressure. Once a panic brake
application is detected, the system will remain activated as long as the
brake pedal is pressed or ABS is engaged. The system is deactivated by
either releasing the brake pedal or coming to a complete stop. When the
system activates, noise from the ABS pump motor and brake pedal
pulsation may be observed; this is normal.

WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracwith RSCsystem is an indication that
at least some of the tires have exceeded their ability to grip the road;
this could reduce the operator’s ability to control the vehicle,
potentially resulting in a loss of vehicle control, vehicle rollover,
personal injury and death. If your AdvanceTracwith RSCsystem
activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracwith RSCsystem, the stability control light will
illuminate steadily. Verify that the AdvanceTracwith RSCsystem is
not manually disabled. Press the stability control button located on the
instrument panel to the right of the climate control system. If the
stability control light still illuminates steadily, have the system serviced
by an authorized dealer immediately. Operating your vehicle with
AdvanceTracwith RSCdisabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTracwith RSCsystem automatically enables each time
the engine is started. All features of the AdvanceTracwith RSCsystem
(TCS, ESC, and RSC) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.

Note:Noise from the ABS pump motor may be observed during hill
descent control operation. This is a normal characteristic of the ABS and
should be no reason for concern.
Hill descent modes
•At speeds below 20 mph (32 km/h): When the HDC switch is pressed
and HDC is active, the HDC telltale will flash.
•At speeds below 20 mph (32 km/h): When the HDC switch is pressed
and conditions are not correct for hill descent activation, the HDC
system will be enabled, the light in the cluster will be on solid and
HILL DESCENT CONTROL READY will be displayed in the message
center.
•At speeds above 20 mph (32 km/h): When the HDC switch is pressed,
the HDC system will be enabled, the light in the cluster will not be
illuminated and FOR HILL CNTRL, 20 MPH OR LESS will be displayed
in the message center.
Refer toMessage centerin theInstrument Clusterchapter for hill
descent control messages.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
•Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components

•loose or worn steering components
•improper steering alignment
If any steering components are serviced or replaced, install new
fasteners (many are coated with thread adhesive or have prevailing
torque features which may not be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
ELECTRONIC LOCKING DIFFERENTIAL (ELD) (IF EQUIPPED)
The electronic locking differential (ELD) is a device housed in the rear
axle which allows both rear wheels to turn at the same speed. It provides
added traction on slippery and/or off road surfaces, particularly when
one wheel is on a poor traction surface. The ELD may be locked or
unlocked by the vehicle operator and can be engaged or disengaged on
the fly. When the axle is unlocked it will function like a standard rear
axle. When the axle is locked it will not allow the rear wheels to rotate
at different speeds when turning. It is not recommended for use on good
traction surfaces such as dry pavement. Doing so may result in abnormal
driving behavior and noise while cornering and excessive tire wear.
The ELD is affected by the following conditions of your vehicle:
•On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High),
the ELD will not engage if the vehicle speed is above 25 mph
(40 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 19 mph
(30 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 (ELD)
For vehicles equipped with an
electronic shift 4WD system:
Pull the knob on the 4WD control
toward you. The
indicator light
will display in the instrument
cluster.
Driving
277
2011 F-250/350/450/550(f23)
Owners Guide, 1st Printing
USA(fus)

For 2WD vehicles and vehicles
equipped with a manual shift
4WD system:
Turn the control to ON. The
indicator light will display in the
instrument cluster.
Once the
light is displayed in the instrument cluster, both rear wheel
axle shafts will be locked together providing added traction.
If the
indicator light in the instrument cluster turns off, 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 will be accompanied by the
CHECK LOCKING DIFFERENTIAL message in the message center.
See your authorized Ford dealer for assistance.
Note:The ELD may have difficulty disengaging either by operator
command or automatically if the driveline is under torque. If driving
conditions allow, releasing the accelerator pedal or turning the steering
wheel in the opposite direction may assist in disengagement.
Note:The ELD is designed for off-road use only and is not intended for
use on dry pavement.
PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
