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 improves
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.
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.

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 323). See
Warning Lamps and
Indicators (page 100).
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
locked in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. 192

TRAILER SWAY CONTROL (If
Equipped) 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 (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation. Note:
This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message
TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See
Load
Carrying (page 233).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed a trailer
weight of
5100 lb (2,313 kg) when
towing with, or by, bumper only. Note:
Do not exceed a trailer
weight of
5100 lb (2,313 kg) if your
vehicle is not equipped with a
Heavy Duty Trailer Towing
Package.
Note: Make sure to take into
consideration trailer frontal area.
Vehicles not equipped with the
Trailer Tow Package or the Heavy
Duty Payload Package should not
exceed 36.6 feet 2
(3.4 meters 2
)
trailer frontal area. Vehicles
equipped with the Trailer Tow
Package or the Heavy Duty Payload
Package should not exceed 60
feet 2
(5.6 meters 2
) trailer frontal
area.
Note: Exceeding this limitation
may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per
1000 ft (305 m) starting
at the 1000 ft (305 m) elevation
point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as your
vehicle's electrical system may not
include the wiring connector
needed to use electric trailer
brakes.

Note:
If completed successfully, the
information display shows NEUTRAL TOW
LEAVE IN N or NEUTRAL TOW ENABLED
LEAVE TRANSMISSION IN NEUTRAL.
This indicates that your vehicle is safe to
tow with all wheels on the ground.
Note: If you do not see the message in the
display, you must perform the procedure
again from the beginning.
Note: You may hear an audible noise as the
transfer case shifts into its neutral position.
This is normal.
6. Leave the transmission in position
N
and turn the ignition as far as it will go
toward the off position (it will not turn
fully off when the transmission is in
position
N). If your vehicle has an
ignition key, you must leave the key in
the ignition while towing. To lock and
unlock your vehicle, use the keyless
entry keypad or extra set of keys. If your
vehicle has intelligent access, press the
engine
START/STOP button once
without pressing the brake pedal. You
do not need to leave your keys in the
vehicle. You can lock and unlock your
vehicle as you normally do.
7. Release the brake pedal. WARNINGS
Do not disconnect the battery during
recreational towing. Doing so will
prevent the transfer case from
shifting properly and may cause the vehicle
to roll even if the transmission is in P
(Park). Shifting the transfer case to its
neutral position for recreational
towing may cause the vehicle to be
able to roll even if the transmission is in P
(Park). The driver or others could be
injured. Make sure the foot brake is
depressed and the vehicle is in a secure
and safe position while the transfer case
is being shifted to its neutral position. WARNINGS
Failing to put the transfer case in its
neutral position will damage vehicle
components.
Note:
You can check four-wheel-down
towing status at any time by opening the
driver's door or turning the ignition to the
accessory or on position and verifying the
NEUTRAL TOW ENABLED
message
displays in the cluster.
To exit four-wheel-down towing and return
the transfer case to its
2H position:
1. With your vehicle still properly secured
to the tow vehicle, put the ignition in
the on position, but do not start the
engine. If your vehicle has an ignition
key, turn the key to on. If your vehicle
has intelligent access, press the engine
START/STOP
button once without
pressing the brake pedal.
2. Press and hold the brake pedal.
3. Shift the transmission out of N and into
any gear.
4. Release the brake pedal.
Note: If completed successfully, the
instrument cluster displays
4X2, and
NEUTRAL TOW DISABLED.
Note: If the indicator light and message do
not display, you must perform the procedure
again from the beginning.
Note: You may hear an audible noise as the
transfer case shifts out of its neutral
position. This is normal.
Note: If
SHIFT DELAY PULL FORWARD
displays in the instrument cluster, transfer
case gear tooth blockage is present. See the
instructions after this section.
5. Apply the parking brake, and then disconnect the vehicle from the tow
vehicle.

•
Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
• Close the windows for high-speed
driving.
DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle.
Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so: •
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury. Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are
supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to make sure mats do not shift out of
position. Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to
prevent them from moving and interfering
with the pedals or the ability to control the
vehicle. Never place floor mats or any other
covering on top of already installed
floor mats. Floor mats should always
rest on top of vehicle carpeting surface and
not another floor mat or other covering.
Additional floor mats or any other covering
will reduce the pedal clearance and
potentially interfere with pedal operation.
273
F-150 (), enUSA, First Printing Driving HintsE176913
Page 277 of 549

WARNINGS
Check attachment of floor mats on
a regular basis. Always properly
reinstall and secure floor mats that
have been removed for cleaning or
replacement. Always make sure that objects
cannot fall into the driver foot well
while the vehicle is moving. Objects
that are loose can become trapped under
the pedals causing a loss of vehicle control. Failure to properly follow floor mat
installation or attachment
instructions can potentially cause
interference with pedal operation causing
a loss of vehicle control. To install floor mats, position the floor mat
so that the eyelet is over the retention post
and press down to lock in.
To remove the floor mat, reverse the
installation procedure.
SNOWPLOWING
We recommend the four-wheel drive F-150
in XL, XLT or Lariat trim levels with the 5.0L
engine and snowplow option for residential
snowplowing only. We do not recommend
the F-150 with the automatic four-wheel
drive system for snowplowing. Do not use F-150 vehicles equipped with
the 2.7L or 3.5L engines for snowplowing.
Installing the Snowplow
Weight limits and guidelines for selecting
and installing the snowplow are in the Ford
Truck Body Builders Layout Book,
snowplow section, found at
www.fleet.ford.com/truckbbas.
A typical installation affects the following:
•
Certification to government safety laws
such as occupant protection and airbag
deployment, braking, and lighting. Look
for an Alterer ’s Label on your vehicle
from the snowplow installer certifying
that the installation meets all
applicable Federal Motor Vehicle
Safety Standards (FMVSS).
• The Front Gross Axle Weight Rating
(GAWR) is on the upper left side of the
vehicle ’s Safety Compliance
Certification Label. This is the total
weight that front axle supports, which
includes the vehicle weight plus any
auxiliary equipment such as snowplow
frame-mounted hardware that can be
added to the vehicle and satisfy Ford
compliance certification to FMVSS. Do
not exceed FGAWR or Gross Vehicle
Weight Rating (GVWR).
• Rear ballast weight behind the rear
axle may be required to prevent
exceeding the FGAWR, and provide
front-to-rear weight balance for proper
braking and steering.
• Front wheel toe may require
re-adjustment to prevent premature
uneven tire wear. Specifications are in
the Ford Workshop Manual.
• Headlight aim may require adjustment.

Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile
manufacturers.
1. Check the engine oil level.
2. If the engine oil level is not within the
normal range, add engine oil that
meets Ford specifications. See
Capacities and Specifications (page
359
).
3. Remove the engine oil filler cap and use a funnel to pour the engine oil into
the opening.
4. Wipe off any spilled oil.
5. Recheck the engine oil level. Make sure
the oil level is not above the normal
operating range on the engine oil level
dipstick.
6. Install the engine oil level dipstick and ensure it is fully seated.
7. Fully install the engine oil filler cap by turning the filler cap clockwise until
three clicks are heard or until the cap
is fully seated.
ENGINE COOLANT CHECK WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, spilling
coolant on hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield. WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly. Do not add coolant further than the
MAX mark.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information.
See
Scheduled Maintenance (page 518).
Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair Coolant and
Battery Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.

Adding Engine Coolant
Note:
Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. Your warranty may not
cover these damages.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red.
As long as the engine coolant is clear and
uncontaminated, this color change does
not indicate that the engine coolant has
degraded, nor does it require that qualified
personnel drain the engine coolant, flush
the system or replace the engine coolant.
Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine ’s cooling
system. The use of an improper coolant
may harm engine and cooling system
components and may void the warranty.
Use prediluted engine coolant meeting the
Ford specification. See Capacities and
Specifications (page 359).
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system with Motorcraft Premium Cooling
System Flush.
3. Refill with engine coolant as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol. •
Brine.
• Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure will escape as you unscrew the cap.
2. Add prediluted engine coolant meeting
the Ford specification. See
Capacities
and Specifications (page 359).
3. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
4. If necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed
of in an appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.
