Fuel in the fuel system remains under high pressure
even when the engine is not running. Before working
on or disconnecting any of the fuel lines or fuel system
components, the fuel system pressure must be relieved.
Failure to do so can result in personal injury.
Do not smoke or carry lighted tobacco or open ame
of any type when working on or near any fuel-related
components. Highly ammable mixtures are always
present and can be ignited, resulting in personal injury.

CAREFULLY READ THE IMPORTANT SAFETY
PRECAUTIONS and WARNINGS BEFORE PROCEEDING
WITH THE REPAIRS!
Appropriate disassembly, assembly methods and
procedures are essential to ensure the personal safety
of the individual performing the kit installation. Improper
installation due to the failure to correctly follow these
instructions could cause personal injury or death. Read
each step of the manual carefully before starting the
installation.
Perform this installation on a good clean level surface
for maximum safety and with the engine turned off
• Always wear safety glasses for eye protection.
• Place the ignition switch in the OFF position.
•
Always apply the parking brake when working on
the vehicle.
•
Block the front and rear tire surfaces to prevent
unexpected vehicle movement.
•
Operate the engine only in well-ventilated areas to
avoid exposure to carbon monoxide.
•
Do not smoke or use ammable items near or around
the fuel system.
•
Use chemicals and cleaners only in well-ventilated
areas.
•
Batteries can produce explosive hydrogen gas which
can cause personal injury. Do not allow ames, sparks
or ammable sources to come near the battery.
•
Keep hands and any other objects away from the
radiator fan blades.
• Keep yourself and your clothing away from moving
parts when the engine is running.
•
Do not wear loose clothing or jewelry that can be
caught in rotating or moving parts.
•
Premium fuel (91 octane or higher) is required to
prevent “spark-knock” or detonation under certain
operating conditions.
•
The use of fuel additives (i.e. octane boosters) is
not recommended. There is a possibility that these
chemicals can damage your engine and cause
drivability issues with your vehicle and void your
warranty.
•
Operating your engine without the ROUSH PCM
recalibration will result in engine damage or failure
and will void your warranty.
• 5W50 oil is required.

Exterior Maintenance
To protect your vehicle’s exterior nish and graphic
decals (if applicable), it is important to wash your vehicle
often. Industrial fallout, road tar, bird droppings, tree
sap, and other foreign matter can damage the nish on
your vehicle.
Washing
Before washing, rinse your vehicle with clean water
to remove any surface contamination. Next, wash the
vehicle from top to bottom using a soft sponge or wash
mitt with a mild vehicle wash soap. Finally, rinse the
vehicle thoroughly and wipe it dry with a soft towel or
chamois. To complete the job, carefully clean the door
jambs and joints between the doors, hood, and trunk of
your vehicle with a damp cloth. Never wipe a dry surface,
as ne scratches in your paint will result. The non-gloss
paint nish of the front exterior grille and bumper cover
should be handled carefully as excessive contact will
create smooth paint surfaces and effect gloss level.
NOTE:
ROUSH recommends hand washing your vehicle. If
your vehicle is equipped with decals, such as stripes,
do not use a commercial or high-pressure wand on
the striped surfaces or stripe edges. Damage resulting
from an automatic car wash or high-pressure wand is
not covered under your warranty.
NOTE:
•
Maintain a minimum distance of approximately 16
inches (40 cm) between the vehicle body and the
wash nozzle.
•
When washing around the door glass, increase the
distance to 40 inches (1m) and spray at right angles
to the glass surface.
Waxing
ROUSH recommends that you wax your vehicle at least
twice a year, or when painted surfaces do not shed
water well. Make sure your vehicle is clean and dry
before waxing. As with washing, do not apply wax in
direct sunlight.
Note: Do not get wax on any of the decals or graphics.
VEHICLE INFORMATION
Build Data
ROUSH Performance emissions certication information
is recorded on the ROUSH Performance Vehicle Emissions
Control Information (VECI) labels. The labels are vehicle-
specic and are required by law to be on the vehicle to
which it is assigned along with the Ford VECI label.
VEHICLE CARE
Interior Maintenance
Leather Seats
Real leather is not uniform and may have scars, scratches,
and wrinkles. To clean your leather, use a mild soap or
leather cleaner and wipe it with a damp soft cloth. Buff
the leather after cleaning with a dry, soft cloth.
Vinyl
Vinyl can be cleaned either with a mild soap and water
solution or commercially available products. At times, it
may be necessary to use a soft bristled brush to remove
stubborn stains or dirt from the surface.
Carpet
Vacuum the carpet frequently to remove dirt. Ground-in
dirt will make the carpet wear prematurely. Use a foam
type carpet shampoo periodically to keep your carpet
looking new. Follow the instructions that are supplied
with the cleaner but be careful to not oversaturate the
carpet as it may take an excessive amount of time to dry.
Setting the Console Safe Combination
1. The combination is factory-set at 0 - 0 - 0 - 0.
2. The combination must be on the opening number
prior to resetting.
3. On the underside outer edge of the lock, there is a
hole for the code reset button. Rotate the face of the
cam until the code reset button comes into view.
4. Push this pin in with a paper clip and keep it pushed
in.
5. Set your personal combination by turning the dials
to the desired combination.
6. Release the reset button and your new combination
is set.
7. To lock, rotate the lock to the “Locked” position.
Rotate one or more dials after the lock is closed.
8. Then, to open the lock, turn dials to your personal
combination.

Reach through the opening of the front bumper cover
panel, align a pick tool in the center of the bottom
bosses on the front bumper cover panel. Using the
pick tool, push into the center of the boss to create
a locator hole on the outside face of the part. Repeat
this process for the other bottom boss.

power drill with a 11/64” drill bit.
3.
Drill two (2) holes using a 11/64” drill bit at the locator
