Recommended Shift Speeds for Maximum Fuel Economy
Upshift according to the following chart:
Upshifts when accelerating
Shift from:
1 - 2 11 mph (18 km/h)
2 - 3 18 mph (29 km/h)
3 - 4 25 mph (40 km/h)
4 - 5 30 mph (48 km/h)
5 - 6 43 mph (69 km/h)
Operating at High Speeds
Equipped with the SVT Track Pack, your SVT vehicle is capable of
sustained high speeds and track day driving. All Shelby GT500’s are
equipped with tires rated for the vehicle’s maximum speed. Remember to
drive safely, obey all traffic laws and only operate your SVT vehicle at
high speeds at locations equipped and designed to do so safely. Before
operating your vehicle at high speeds, follow these guidelines.
•Verify your tires have the correct tire pressures (seeTiresin this
supplement).
•Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
•Do not operate your vehicle at high speeds with more than two
passengers or while carrying cargo.

7. Add prediluted coolant to the coolant reservoir until the coolant level
is between the MIN and MAX marks on the reservoir.
8. Reinstall the pressure relief cap.
9. Check the coolant level in the reservoir before you drive your vehicle
the next few times (with the engine cool).
10. If necessary, add prediluted coolant to the coolant reservoir until the
coolant level is between the MIN and MAX marks on the reservoir.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add prediluted coolant to bring the coolant level to the proper
level.
If you have to add more than 1.0 quart (1.0 liter) of coolant per month,
have your dealer check the cooling system. Your cooling system may
have a leak. Operating an engine with a low level of coolant can result in
engine overheating and possible engine damage.
ENGINE SPARK PLUG INTERVAL
To keep your high performance engine operating at peak performance,
the spark plug service interval is every 45,000 miles (72,000 kilometers).
See the Motorcraft® Part Numbers chart for the specific spark plug
application.
OCTANE RECOMMENDATIONS
Premium unleaded gasoline with an
(R+M)/2 octane rating of 91 or
higher is required. SVT recommends
using unleaded gasoline with octane
rating of 93 or higher for optimal
performance of this vehicle.
Recommended fuel is an important part of the proper maintenance and
optimal performance of this vehicle. The use of gasoline with an octane
rating lower than 91 can lead to severe mechanical damage to your
vehicle, may degrade vehicle performance, and may affect your warranty
coverage.

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed below:
Normal vehicle axle maintenance:Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3000 miles (4800 kilometers) or three months,
whichever comes first. This interval can be waived if the axle is filled
with 75W85 Premium Synthetic Hypoid Gear Lubricant meeting Ford
specification WSS-M2C942–A, part number XY–75W85–QL or equivalent.
Add friction modifier XL-3 (EST-M2C118-A) or equivalent for complete
refill of Traction-Lok rear axles (refer to theCapacities and
Specificationschapter for details).
Police/Taxi/Livery vehicle axle maintenance:Change rear axle fluid
every 100000 miles (160000 km). Rear axle fluid change may be waived if
the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent. Add
four ounces (118 mL) of additive friction modifier XL-3 (EST-M2C118-A) or
equivalent for complete refill of Traction-Lok rear axles. The axle fluid
should be changed anytime the axle has been submerged in water.
California fuel filter replacement:If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the vehicle’s
useful life. Ford Motor Company, however, urges you to have all
recommended maintenance services performed at the specified intervals
and to record all vehicle service.
Hot climate oil change intervals:Vehicles operating in the Middle
East, North Africa, Sub-Saharan Africa or locations with similar climates
using an American Petroleum Institute (API) Certified for Gasoline
Engines (Certification mark) oil of SM or SN quality, the normal oil
change interval is 5000 miles (8000 kilometers).
If the available API SM or SN oils are not available, then the oil change
service interval is 3000 miles (4800 kilometers).
Engine air filter replacement:Engine air filter life is dependent on
exposure to dusty and dirty conditions. Vehicles operated in these conditions
require frequent inspection and replacement of the engine air filter.
