2008 FORD F150 traction control

During Traction Control™ operation,
the traction control active light will
illuminate and the engine will not
“rev-up” when you push further on
the accelerator. This is normal
system behavior and should be no
reason for concern.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control™
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
The Traction Control™ switch,
located on the center console, has
an indicator light that illuminates
when the system is off. The Traction
Control™ system will automatically
turn on every time the ignition is
turned off and on. The Traction
Control™ system should normally
be left on.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching the Traction Control™ system off. This may allow
excess wheel spin to “dig” the vehicle out and enable a successful
“rocking” maneuver. Remember to switch the Traction Control™ system
back on once the vehicle is no longer stuck.
If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
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 a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering fluid level
(below the MIN mark on the reservoir).

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 4WD control between 2H and 4H at 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 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.

Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
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.Avoid driving crosswise or turning on steep
slopes or hills. 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. Rapid pumping of the brake pedal will help you slow the vehicle
and still maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
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).
Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
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.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
