temperature reaches 170°F (77°C). Warm up is indicated when the redline
indicator band starting point changes from 6250 rpm to 7000 rpm.
Your vehicle is equipped with an over-rev feature to increase the
performance range of your Shelby GT500. When conditions permit,
over-rev is indicated on the tachometer with redline marked at 7000 rpm.
If conditions limit over-rev accessibility, the band is illuminated red from
6250 rpm to 7000 rpm.

Once the engine is warm, the over-rev feature allows eight seconds above
6250 rpm up to 7000 rpm. If the eight second time limit is exceeded, the
maximum engine rpm is reduced to 6250 rpm until both of the following
occurs:
•Engine is operated for at least 15 seconds below 6000 rpm
•Engine rpm falls below 5000 rpm.
Do not operate the engine at high rpm and low load for sustained
periods of time, as damage may occur.
GROUND CLEARANCE
Your vehicle is designed for high speed capability and has been
aerodynamically tuned to reach 200 mph (322 km/h) when properly
equipped. Some of the aerodynamic tuning has been achieved with the
lower front air dam, which is attached below the front splitter. The lower
front air dam is removable with basic tools to suit your driving
conditions, especially if they include steep driveway angles, rough roads,
high curbs or harsh climates.
Since ground clearance is reduced, use caution when approaching curbs
or curb stops from the front and rear as vehicle damage will occur.
Additionally, when crossing speed bumps or driveway curbs, SVT
recommends approaching at a 45 degree angle to reduce the risk of
vehicle damage.
The Shelby GT500 carries the same warranty as other Ford Mustang
models. Damage caused by accidents, collision or objects striking the
vehicle (including driving through a car wash) or misuse of the vehicle,
such as driving over curbs, overloading, racing or using the vehicle as a
permanent stationary power source is not covered under the new vehicle
limited warranty. See the Warranty Guide for complete information.

DRIVING YOUR SHELBY GT500 THROUGH WATER
The Ford Shelby GT500 has aerodynamic devices attached to the
underbody designed to help control airflow for superior performance.
Therefore, the driver must be especially careful to avoid driving through
deep or standing water. If driving through deep or standing water is
unavoidable, do not exceed 10 mph (16 km/h). Never drive through
water that is higher than the bottom of the wheel rims. Water may enter
through the air intake due to the vacuum generated in the engine.
Damage caused by the intake of water in the engine is not covered by
the warranty.
WASHING YOUR SHELBY GT500
Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track. Wash
your vehicle by hand, or by using a touchless commercial wash with no
mechanical tracks on the floor. Do not use a power washer or high
pressure wand on the striped surfaces or stripe edges. Refer to the
Owner’s Manualfor information on cleaning products and vehicle care.
To maintain proper cooling and aerodynamics at high speeds, your
vehicle has heat exchangers integrated with the front fascia designed to
maximize performance.
Note:Do not use a power washer or high powered spray nozzle as
damage to the fins could occur.
Note:For heavy accumulation of debris or dirt, clean with a non-metallic
soft bristle car wash brush and warm soapy water as needed.

WHEELS
Your SVT vehicle is equipped with unique wheels matched to the tires.
These wheels are more susceptible to damage due to their diameter,
width and low profile tires. To avoid damage to your wheels:
•Maintain proper tire pressure (seeTiresin this supplement).
•Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track. Wash
your vehicle by hand, or by using a touchless commercial wash with
no mechanical tracks on the floor. Do not use a commercial or high
pressure wand on the striped surfaces.
•When installing wheels, always torque lug nuts to specification with a
torque wrench.
•Inspect your wheels for damage on a regular basis. If a wheel is
damaged, replace it immediately.
•In the event that you encounter an abnormally harsh impact, inspect
the outer diameter of your wheels, both inside and out, for damage.
Wheel Lug Nut Torque Specifications
WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make sure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).

TIRE INFORMATION
Your SVT vehicle is equipped with unique wheels and tires designed to
enhance performance. To continue providing this performance, extra
care must be taken when operating and maintaining your vehicle.

Tires
Your SVT vehicle is equipped with low profile, high performance tires
that are designed to optimize the driving dynamics you expect in a SVT
vehicle. These tires are not optimized for off-road or winter (snow or
cold weather) performance, and their ride, noise and wear characteristics
are different than non-performance tires. Also, because of their lower
profile, the tires are more susceptible to damage due to potholes and
rough roads. To make sure that your tires perform as intended, it is
important that you maintain your tires properly:
•The Shelby GT500 original equipment tires are optimized for
performance in both wet and dry conditions. Ford does not
recommend using the original equipment tires when temperatures
drop to approximately 40°F (5°C) or below (depending on tire wear
and environmental conditions) or in snow/ice conditions.
•The Shelby GT500 P265/40-19 front, P285/35-20 rear directional tires
were designed for track use and may exhibit significantly reduced
tread life and increased tire noise compared to the standard
equipment tires under normal driving conditions. Increasing the front
camber settings beyond the factory settings may further accelerate
tread wear and induce tire noise.
•Note:Do not use tire chains on the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•For tire pressures, see the placard located on the B-pillar inside the
driver’s door.
•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, 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
your 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 your alignment
checked.
•Rotate tires as recommended in the following sectionTire rotation.
•When replacing tires, the only way to maintain original performance is
to use the original equipment tire. If a different tire is used, it should
be the same size, speed rating and load rating and be replaced as a set
of four. Never mix tire brands.
WARNING:For vehicles equipped with performance package
tires (P265/40-19 front, P285/35-20 rear), only replace wheels
and tires with the EXACT original brand, size and construction tire
with which your vehicle was originally equipped. Use of any other
wheel/tire combinations, even with identical size ratings, may result in
insufficient running clearances, tire rubbing and eventual puncture.
Loss of tire pressure could lead to a loss of vehicle control leading to
serious injury or death.

Summer Tires
The Shelby GT500 is equipped with D.O.T. approved ultra high
performance summer tires with track capability. The rubber compounds
used in these tires lose flexibility and may develop surface cracks in the
tread area at temperatures below 20°F (-7°C). Always store your tires
indoors at temperatures above 20°F (-7°C). If the tires have been
subjected to 20°F (-7°C) or less, warm them in a heated space to at least
40°F (5°C) for at least 24 hours before installing them on a vehicle, or
moving the vehicle with the tires installed, or checking tire inflation. Do
not place tires near heaters or heating devices used to warm the room
where the tires are stored. Do not apply heat or blow heated air directly
on the tires. Always inspect the tires after storage periods and before
use as outlined in theOwner’s Manual. Ford does not recommend using
these high performance summer tires when temperatures drop to
approximately 40°F (5°C) or below, or in snow or ice conditions.
Winter Driving
The original equipment tires on your SVT vehicle are designed for
maximum performance in dry and wet summer conditions. They are not
designed for winter use on ice or snow and cannot be used with snow
chains. If you will be operating your vehicle in these conditions, winter
or all-season tires must be used.
•Use winter tires with a V speed rating and a 93 load index or higher
for all models. You may also use P255/40R19 winter tires with a V
speed rating and a 93 load index and 19 inch wheels from the
2010-2012 model year Shelby GT500. Using these wheels will provide
adequate brake and suspension clearance.
•Do not use a winter tire with less than a V speed rating, and even
with clear, dry driving conditions do not operate your vehicle above
posted speed limits while using winter tires. Never perform high speed
driving with winter tires.
Please call the Ford Performance Info Center at 1-800-FORD-SVT
(367-3788) for specific winter tire recommendations.
Tire Rotation
Note:Your Shelby GT500 tires (P265/40-19 front, P285/35-20 rear) are
directional. Tire rotation is not recommended for directional tires.
Note:If your tires show uneven wear, ask an authorized dealer to check for
and correct any wheel misalignment, tire imbalance or mechanical problems.
