2011 FORD F150 warning

•Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.
How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of power per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
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.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
Parking brake
To set the parking brake (1), press
the parking brake pedal down until
the pedal stops.
The BRAKE warning lamp will
illuminate and will remain
illuminated until the parking brake
is released.
To release, pull the lever (2).

WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
Brake override
This vehicle is equipped with a brake override feature. In the event the
accelerator pedal becomes stuck or entrapped, applying steady and firm
pressure to the brake pedal will both slow the 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 P (Park) and apply
the parking brake, and then inspect the accelerator pedal for any
interferences. If none are found and the condition persists, have your
vehicle towed to the nearest dealer.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSCsystem provides the following stability
enhancement features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides.
•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over.
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:When a failure has been detected with the
AdvanceTracwith RSCsystem, the stability control light will
illuminate steadily. AdvanceTracwith RSCcan be disabled manually
by pressing the stability control off button located on the center of the
instrument panel. When the system is disabled, the stability control off
light will illuminate. 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.
The AdvanceTracwith RSC
system includes a stability control
off button located on the center of
the instrument panel.
There are two stability control lights
in the instrument cluster. The stability control light in the instrument
cluster will flash if a driving situation causes the AdvanceTracwith
RSCsystem to operate. If the stability control light illuminates steadily,
have the system serviced by an authorized dealer immediately.
Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.

Trailer sway control
Your vehicle is equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTracwith
RSCsystem to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.Note:When trailer sway control is
activated, cruise control is disabled.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The message center will also
displayTRAILER SWAY REDUCE SPEED.In some cases when trailer
sway is detected, the vehicle speed is too high and may be above a
Driving
285

USA(fus)

speed at which trailer sway will not grow continuously. This may cause
the system to activate multiple times, causing a gradual reduction in
speed.
Note:The trailer sway control will only activate at speeds greater than
31 mph (50 km/h).
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. See trailer
sway control under theMessage centerin theInstrument Cluster
chapter. Note that regardless of chosen enable state, trailer sway control
will be re-enabled at each new key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
STEERING
3.7L, 5.0L and 3.5L EcoBoost™ engines:
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin theDriver
Controlschapter for more information.

WARNING:The EPS system has diagnostics checks that
continuously monitor the EPS system to ensure proper operation
of the electronic system. When an electronic error is detected, the
message POWER STEERING ASSIST FAULT will be displayed in the
message center. If this happens, stop the vehicle in a safe place, and
turn off the engine. After at least 10 seconds, reset the system by
restarting the engine, and watch the message center for POWER
STEERING ASSIST FAULT. If the message returns, or returns while
driving, take the vehicle to your dealer to have it checked. With the
message displayed, the steering assist is turned off, making the vehicle
harder to steer.
WARNING:If the message SERVICE POWER STEERING is
displayed in the message center, the EPS system has detected a
problem with the system function. On the next key cycle the message
SERVICE POWER STEERING NOW will be displayed and steering
assist will be removed until the steering system is serviced. Have your
vehicle taken to the nearest dealer as soon as possible.
6.2L engine:Your vehicle is equipped with a hydraulic steering system.
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
a few seconds when the engine is running. 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.
•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
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized 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.

All engines
If the steering wanders or pulls equipped with either an EPS or a
hydraulic steering system, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
LIMITED-SLIP AXLE (IF EQUIPPED)
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 in tight turns with low vehicle speed. This is
normal behavior and indicates the axle is working.
Electronic locking differential (ELD) axle (if equipped)
This axle provides added traction on slippery and/or off-road surfaces,
particularly when one wheel is on a poor traction surface. In normal
driving conditions the rear axle function as a standard axle. The ELD
may be locked or unlocked by the vehicle operator. Refer toFour-wheel
drive (4WD) operationsection in this chapter for further detail on ELD
function and usage. 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. The ELD axle is not
recommended for use on good traction surfaces such as dry pavement.
Doing so may result in abnormal driving behavior while cornering and
excessive tire wear.
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.
