traction control FORD RANGER 1999 2.G Owners Manual

Using the electronic shift 4WD system (if equipped)
Positions of the electronic shift system
2WD (2WD High)± Power to rear axle only.
4X4 HIGH (4WD High)± Power delivered to front and rear axles for
increased traction.
4X4 LOW (4WD Low)± Power to front and rear axles at low speeds.
Shifting from 2WD (2WD high) to 4X4 HIGH (4WD high)
Move the 4WD control to the 4X4
HIGH position.
At temperatures below 0ÉC (32ÉF),
shifts from 2WD to 4X4 HIGH
should not be performed above 72
km/h (45 mph).
²Do not shift into 4X4 HIGH with
the rear wheels slipping.
Shifting from 4X4 HIGH (4WD high) to 2WD (2WD high)
Move the 4WD control to 2WD
position at any forward speed. You
do notneed to put the gearshift in
R (Reverse) to disengage your front
hubs.
Shifting from 2WD (2WD high) to 4X4 LOW (4WD low)
1. Bring the vehicle to a stop.
2. Depress the brake.
3. Place the gearshift in N (Neutral) (automatic transmission) or depress
the clutch (manual transmission).

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
D (Drive).
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.
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.
Extended use of other than the manufacturer's specified size tires on a
Traction-Lok rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
To avoid injury, never run the engine with one wheel off the
ground, such as when changing a tire.

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 grade 150 would wear one
and one-half (1 1/2) times as well on the government course as a tire
grade 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
Driving too fast for conditions creates the possibility of loss of
vehicle control. Driving at very high speeds for extended periods
of time may result in damage to vehicle components.
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 snow tires and chains,it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
²Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
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.
