2008 FORD F150 wheel

•Some noise is normal during operation. If the noise is excessive, check
for a low power steering fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by a low power
steering fluid level. Check for a low power steering fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering fluid reservoir above the MAX mark on
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
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK 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
Traction-Lok 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.
PREPARING TO DRIVE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
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.

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.
Understanding the gearshift positions of the 4–speed automatic
transmission
Your vehicle’s automatic transmission is equipped with a special shift
strategy that ensures maximum heater performance during cold weather
operation.
When ambient temperature is 23°F (–5°C) or below and the engine
coolant temperature is below 100°F (38°C), light throttle upshifts may be
slightly delayed. Once the engine coolant temperature reaches 160°F
(71°C) the normal shift strategy will resume. This is normal operation
and will not affect the function or the durability of the transmission.
If the normal shift strategy does not resume once the engine
coolant temperature reaches the normal operating temperature,
or if the downshifts and other throttle conditions do not function
normally, see your authorized dealer as soon as possible.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
•Start the engine
•Depress the brake pedal
•Move the gearshift lever into the desired gear
•Release the parking brake.

camera system, at least in the dark, until the lamp(s) are replaced and
functioning.
Servicing
•If the vehicle is in R (Reverse) and the screen in the rear view mirror
appears blue for three seconds and turns blank afterwards, the camera
is not working properly; have the system inspected by your authorized
dealer.
•If the image comes on while the vehicle is not in R (Reverse), have
the system inspected by your authorized dealer.
•If the vehicle is in R (Reverse) and the screen is blank and no blue
screen is observed, the mirror is not working properly; have the
system inspected by your authorized dealer.
•If the image is not clear, then check if there is anything covering the
lens such as dirt, mud, ice, snow, etc. If the image is still not clear
after cleaning, have your system inspected by your authorized dealer.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on dry pavement; driveline damage may occur.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage past 4WD High. This is normal and
should be no reason for concern.Refer toShifting to/from 4L (4WD
Low)for proper operation.

Using a manual 4WD system (if equipped)
2H (2WD High)– Power to the rear wheels only; used for street and
highway driving. Provides optimal smoothness and fuel economy at high
speeds.
4H (4WD High)– Used for extra traction such as in snow or icy roads
or in off-road situations. Not intended for use on dry pavement.
N (Neutral)– No power to either front or rear wheels.
4L (4WD Low)– Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. 4L (4WD Low)
will not engage while the vehicle is moving above 3 mph (5 km/h); this is
normal and should be no reason for concern. Refer toShifting to/from
4L (4WD Low)for proper operation.
Shifting between 2H (2WD high) and 4H (4WD high)
•Move the transfer case lever between 2H (2WD High) and 4H (4WD
High) at a stop or any forward speed up to 55 mph (88 km/h).
Note:Do not perform this operation if the rear wheels are slipping.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a complete stop.
2. Place the transmission in N (Neutral).
3. Move the transfer case lever through N (Neutral) directly to the
desired position.
•If the transfer casewill notengage into 4L (4WD Low), allow the

Note:Some noise may be heard as the system shifts or engages; this is
normal.
Note:For proper operation in 4WD Low, ensure the transfer case shift
lever is moved entirely rearward in to the 4L (4WD Low) position and
that the 4x4 Low light is illuminated.
Note:Ideal 4L (4WD Low) shift conditions occur when the vehicle is
rolling at a speed below 3 mph (5 km/h) and the transmission is in N
(Neutral).
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should only be used when towing the vehicle.
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.

normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a complete stop
2. Place the transmission in N (Neutral).
3. Move the 4WD control to the desired position.
•If shifting into 4L (4WD Low), wait for the 4X4 LOW light in the
instrument cluster to turnonindicating the shift is complete.
•If shifting out of 4L (4WD Low), wait for the 4X4 LOW light in the
instrument cluster to turnoffindicating the shift is complete.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Using the all-wheel drive (AWD) system
(if equipped, Harley-Davidson and Limited only)
This system includes an electronically controlled transfer case. The
system is interactive with the road, continually monitoring and adjusting
torque delivery to the front and rear wheels to optimize traction.
AWD (Auto)- Power delivered to all four wheels, as required, for
increased traction. This is appropriate for all on-road driving conditions,
such as dry road surfaces, wet pavement, snow, gravel and shallow sand.

4H (Lock)- The “4X4 HI” light will illuminate in the instrument cluster
when this position is selected. This position is not recommended for use
on dry pavement. This position is only intended for severe winter or
off-road conditions, such as deep snow, ice or deep sand.
Shifting between AWD (Auto) and 4H (Lock)
Move the control from AWD to 4H at a stop or while driving at any
speed.
Driving off-road with truck and utility vehicles
4WD 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.
How your vehicle differs from other vehicles
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.
Basic operating principles
•Do not use 4WD on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4WD modes are only intended for consistently slippery or loose
surfaces.
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.

If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
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 arenot
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.
If your vehicle gets stuck
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.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Do not spin the wheels at over 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
