is possible that a fuse has blown
and the vehicle's brakelamps may
not be operating properly. Refer to
Fuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle
until you verify that the
brakelamps are working.
If your vehicle gets stuck in mud
or snow it may be rocked out by
shifting from forward and reverse
gears in a steady pattern. Press
lightly on the accelerator in each
gear.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine may
overheat.
Always set the parking
brake fully and make sure
the gearshift is latched in P
(Park). Turn off the ignition
whenever you leave your vehicle.
Driving with a 4±speed
automatic transmission
Understanding gearshift
positions
Pull the gearshift lever towards
you and downward to move the
automatic gearshift.

²GAWR (Gross Axle Weight
Rating): Carrying capacity for
each axle system. The GAWR is
specific to each vehicle and is
listed on the Safety Compliance
Label on the driver's door pillar.
Do not exceed the GVWR
or the GAWR specified on
the Safety Compliance
Certification Label.
Do not use replacement tires with
lower weight capacities than the
originals because they may lower
the vehicle's GVWR and GAWR
limitations. Replacement tires with
a higher weight limit than the
originals do not increase the
GVWR and GAWR limitations.
Your vehicle is classified as a light
duty towing vehicle. It does not
come from the factory fully
equipped to tow. No towing
packages are available through
Ford or Mercury/Lincoln dealers.
Do not tow a trailer until your
vehicle has been driven at least
3 200 km (2 000 miles).
Towing a trailer places an
additional load on your vehicle's
engine, transmission, brakes, tires
and suspension. Inspect these
components carefully after towing.
The amount of weight your loaded
trailer should be no more than
907 kg (2 000 lbs.).

CHANGING THE TIRES
If you get a flat tire while driving,
do not apply the brake heavily.
Instead, gradually decrease your
speed. Hold the steering wheel
firmly and slowly move to a safe
place on the side of the road.
Temporary spare tire
information
Your vehicle may have a temporary
or full-size spare tire. The
temporary spare tire for your
vehicle is labeled as such. It is
smaller than a regular tire and is
designed for emergency use only.
Replace this tire with a full-size
tire as soon as possible.
If you use the temporary
spare tire continuously or
do not follow these precautions,
the tire could fail, causing you to
lose control of the vehicle,
possibly injuring yourself or
others.

To replace the wiper blades:
1. Pull the wiper arm away from
the windshield and lock into the
service position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
with a screwdriver to release the
blade and pull the wiper blade
down toward the windshield to
remove it from the arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
INFORMATION ABOUT TIRE
QUALITY GRADES
New vehicles are fitted with tires
that have their Tire Quality Grade
(described below) molded into the
tire's sidewall. These Tire Quality
Grades are determined by
standards that the United States
Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic tires for use on
passenger cars. They do not apply
to deep tread, winter-type snow
tires, space-saver or temporary use
spare tires, tires with nominal rim
diameters of 10 to 12 inches or
limited production tires as defined
in Title 49 Code of Federal
Regulations Part 575.104(c)(2).

U.S. Department of
Transportation-Tire quality
grades:The U.S. Department of
Transportation requires Ford to
give you the following information
about tire grades exactly as the
government has written it.
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 A B C
The traction grades, from highest
to lowest are A, B, and C, and they
represent the tire's ability to stop
on wet pavement as measured
under test surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Maintenance and care
153

The traction grade
assigned to this tire is
based on braking (straight
ahead) traction tests and does
not include cornering (turning)
traction.
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
154

SERVICING YOUR TIRES
Checking the tire pressure
²Use an accurate tire pressure
gauge.
²Check the tire pressure when
tires are cold, after the vehicle
has been parked for at least one
hour or has been driven less
than 5 km (3 miles).
²Adjust tire pressure to
recommended specifications
found on the Safety Compliance
Certification Label.
Improperly inflated tires
can affect vehicle handling
and can fail suddenly, possibly
resulting in loss of vehicle
control.
Tire rotation
Because your vehicle's tires
perform different jobs, they often
wear differently. To make sure
your tires wear evenly and last
longer, rotate them as indicated in
the ªService Guide.º If you notice
that the tires wear unevenly, have
them checked.
Maintenance and care
155

²Four tire rotation (for vehicles
with aluminum wheels)
²Five tire rotation (for vehicles
with steel wheels and full size
spare tires)
Maintenance and care
156

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier 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 snow tires and chains, you
must install steel wheels of the
same size and specifications as
those originally installed.
Maintenance and care
157

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.
²Do not use tire chains on
aluminum wheels. Chains may
chip the wheels.
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.

ABOUT AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel
tank. The pressure in an
overfilled tank may cause
leakage and lead to fuel spray
and fire.
