1999 FORD F150 traction control

Using the N (Neutral) position
The transfer case neutral position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift
lever position. The vehicle can move forward or backwards.
This position should only be used
when towing the vehicle. Refer to
Wrecker towingin theRoadside
emergencieschapter.
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.
Using the electronic shift 4WD system (if equipped)
Positions of the electronic shift system
2H (2WD High)± Power to rear axle only.
4H (4WD High)± Power delivered to front and rear axles for increased
traction.
4L (4WD Low)± Power to front and rear axles at low speeds.
Shifting from 2H (2WD high) to 4H (4WD high)
Move the 4WD control to the 4H at
a stop or up to 88 km/h (55 mph).
At temperatures below 0ÉC (32ÉF),
shifts from 2H to 4H should not be
performed above 72 km/h (45 mph).
²Do not shift into 4H with the rear
wheels slipping.

Replace rear axle lubricant any time the axle has been submerged in
water. The rear axle does not normally require a lubricant change for the
life of the vehicle. Rear axle lubricant quantities are not to be checked or
changed unless a leak is suspected or repair is required.
Driving on hilly or sloping terrain
When driving on a hill, avoid driving crosswise or turning on steep
slopes. You could lose traction and slip sideways. Drive straight up,
straight down or avoid the hill completely. Know the conditions on the
other side of a hill before driving over the crest.
When climbing a steep 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.
When descending a steep hill, avoid sudden braking. Shift to a lower gear
when added engine braking is desired.
When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button to resume speeds over 50 km/h
(30 mph).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
a lower gear.
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
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.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
Allow more stopping distance and drive slower than usual. Consider
using one of the lower gears.

Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. Those
grades represent the tire's ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
Maintenance and care

Do not replace your tires with ªhigh performanceº tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
²The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
