Tires
Your Ford GT is equipped with low profile, high performance tires that
are designed to optimize handling, steering and braking. These tires are
not designed for off-road or winter performance, and their ride, noise
and wear characteristics are different than other tires. Also, because of
their lower profile, the tires are more susceptible to damage due to
potholes and rough or unpaved roads. To ensure that your tires perform
as designed, it is important that you maintain your tires properly:
•Always maintain your tire pressures according to the tire information
label on the B-Pillar or the edge of the driver ’s door using an accurate
gauge.
• Tire pressures are specified “cold ”and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
• Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
• Do not overload your vehicle. Maximum vehicle and axle weights are
listed on the tire information placard.
• Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
• Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
• In the event that you encounter an abnormally harsh impact, inspect
you tires for damage.
• Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
• Proper suspension alignment is critical for maximum performance and
optimal tire wear. If you notice uneven tire wear, have you alignment
checked.
• Rotate tires as recommended in this section of the Owner Guide.
• When replacing tires, the only way to assure original performance is to
use the original equipment tire.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all electrical accessories except
the audio system and power
windows, which retain power for 10
minutes or until the door is ajar.
This position also locks the steering
wheel and allows key removal.
2. ACC, allows electrical accessories
to operate while the engine is not
running.
3. ON, all electrical circuits are operational and warning lights are
illuminated. Key position when driving.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the engine in this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. See Guarding against exhaust fumes in
this chapter for more instructions.

BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Refer toBrake system warning
light in the Instrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system serviced immediately.)
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle ’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.

STEERING
To 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 pump fluid level
(below the MIN mark on the reservoir). Refer to Checking and
adding power steering power fluid in theMaintenance and
Specifications chapter for information on checking and filling the
power steering fluid reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
LIMITED-SLIP AXLE
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
Extended use of other than the manufacturer ’s specified size tires on a
limited slip 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.
PREPARING TO DRIVE YOUR VEHICLE
Your vehicle has special design features, such as a decreased ground
clearance; care should be taken when driving your vehicle near curbs,
speed bumps and parking lot bump-stops.
Use extra caution while becoming familiar with your vehicle. Know the
capabilities and limitations of both you as a driver and your vehicle.

hot wax treatments used by commercial car washes, tree sap, or other
organic contamination. To clean these items, please follow these tips:
•The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Motorcraft Ultra Clear Spray Glass
Cleaner (ZC-23), available from your dealer.
• Do not use abrasives, as they may cause scratches.
• Do not use fuel, kerosene, or paint thinner to clean any parts.
• Wiper blades can be cleaned with isopropyl (rubbing) alcohol or
windshield washer solution. Be sure to replace wiper blades when they
appear worn or do not function properly.
Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause
damage to the rear window defroster ’s heated grid lines.
INSTRUMENT PANEL AND CLUSTER LENS
Clean the instrument panel with a damp cloth, then dry with a dry cloth.
• Avoid cleaners or polish that increase the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
Do not use chemical solvents or strong detergents when cleaning
the steering wheel or instrument panel to avoid contamination of
the air bag system.
•
Be certain to wash or wipe your hands clean if you have been in contact
with certain products such as insect repellent and suntan lotion in order
to avoid possible damage to the interior painted surfaces.
SAFETY BELTS
For safety belts:
• Remove dust and loose dirt with a vacuum cleaner.
• Remove light stains and soil with Motorcraft Extra Strength
Upholstery Cleaner (ZC-41).
• If grease or tar is present on the material, spot-clean the area first
with Motorcraft Spot and Stain Remover (ZC-14).
• Never saturate the safety belts with cleaning solution.
• Do not use household cleaning products or glass cleaners, which can
stain and discolor the fabric and affect flame retardant abilities.

detected a malfunction. Temporary malfunctions may cause yourCheck
engine/Service engine soon light to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel. After three driving cycles without these or any
other temporary malfunctions present, the Check engine/Service engine
soon light should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If the Check engine/Service engine soon light remains on, have your
vehicle serviced at the first available opportunity.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your Check engine/Service engine
soon light is on, refer to the description in the Warning lights and
chimes section of the Instrument Cluster chapter. Your vehicle may not
pass the I/M test with the Check engine/Service engine soon light on.
If the vehicle ’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test ”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
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 MERCON AT F .
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 in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the “MAX” line
that do not trigger the brake system
warning lamp are within the normal
operating range, there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of your
brake system could be
compromised, seek service from your dealer immediately.
Refer toRemoving Luggage Compartment Liner in this chapter to gain
access to the brake fluid reservoir.
CLUTCH FLUID
Check the fluid level. Refer to the Scheduled Maintenance Guide for the
service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
