²Anticipate stopping; slowing down may eliminate
the need to stop.
²Sudden or hard accelerations may reduce fuel
economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h
[55 mph] uses 15% less fuel than traveling at
105 km/h [65 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Using the air conditioner or defroster may reduce
fuel economy.
²You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
specificationsin this chapter.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle scheduled maintenance guide.

CHECKING AND ADDING POWER STEERING
FLUID
Check the power steering fluid. Refer to the
scheduled maintenance guide for the service interval
schedules. If adding fluid is necessary, use only
MERCONtAT F.
If your vehicle is
equipped with the
3.8L V6 engine,check
the power steering
fluid level with the
engine at normal
operating temperature.
1. Start the engine and
let it run until it
reaches normal
operating temperature
(the engine coolant
temperature gauge
indicator will be near
the center of the
normal area between H
and C).
2. While the engine idles, turn the steering wheel
left and right several times.
3. Turn the engine off.
4. Check the fluid level on the dipstick. It should be
within the FULL HOT range. Do not add fluid if the
level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.

If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. Turn the steering
wheel left and right
several times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be
between the MIN and MAX lines. Do not add fluid if
the level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and refilled as
needed. Refer to the scheduled maintenance guide
for the service interval schedules.

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. The 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.

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. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
²Chains may damage aluminum wheels.
²Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage your vehicle.
²SAE Class S chains may be used on P205/65R15
tires.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.

1Add 118 ml (4 oz.) of Additive Friction Modifier
C8AZ-19B546-A or equivalent meeting Ford
specification EST-M2C118-A for complete refill of
Traction-Lok axles.
Ford design rear axles contain a synthetic lubricant
that does not require changing unless the axle has
been submerged in water.
2Ensure the correct automatic transmission fluid is
used. Transmission fluid requirements are indicated
on the dipstick or on the dipstick handle. MERCONt
and MERCONtV are not interchangeable. DO NOT
mix MERCONtand MERCONtV. Refer to your
scheduled maintenance guide to determine the
correct service interval.
