Brake Burnishing
The brakes should be properly burnished
prior to heavy track use. Excessive brake
noise may occur after the track burnish or
track use. Perform this procedure in a safe
manner on dry pavement, and in
compliance with all local and state
ordinances and laws regarding motor
vehicle operation. How to Burnish the Brakes
Initial low temperature bedding:
•
If your brakes already have 200 mi
(322 km) or more of city driving, skip
this step and go directly to the high
temperature bedding cycle procedure.
Otherwise, perform at least 30 stops
from
50 mph (80 km/h) at 1/3 g
deceleration with 1 mi (1.2 km) spacing
between stops. A deceleration gauge
can be accessed through the
TrackApps menu in your information
display.
High temperature bedding cycle:
• Beginning with cool brakes, perform 15
consecutive stops back to back,
accelerating at 3/4 throttle to
80 mph
(128 km/h) and braking to 20 mph
(32 km/h) at 1.0 g deceleration. The
brakes may omit an odor or smoke
during this part of the procedure.
Cool down:
• Cool the brakes down by driving one or
two laps, 5 mi (8 km)
, at 60 mph
(96 km/h) with minimal to no brake
usage.
Recovery low temperature bedding:
• Perform at least 30 stops from 50 mph
(80 km/h)
at 1/3 g deceleration with
0.7 mi (1.2 km) spacing between stops.
A deceleration gauge can be accessed
through the TrackApps menu in your
information display.

WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
•
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE -
MACH 1
Note: Do not allow water or cleaning
solutions to contact the exposed air filter
element. Cover the air filter assembly and
avoid spraying water at it. CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
Note: Do not allow water or cleaning
solutions to contact the exposed air filter
element. Cover the air filter assembly and
avoid spraying water at it.
