Driving and Operating 245
This procedure should only be
run on a track and only on dry
pavement. Brake pedal fade
will occur during this track
burnish procedure and can
cause brake pedal travel and
force to increase. This could
extend stopping distance until
the brakes are fully burnished.1. Start track lapping at lower speeds and lower
braking efforts for
three minutes of driving.
Allow for increased braking
distances due to reduced
brake output.
2. After Step 1, increase speed and braking effort
for the next six minutes of
lapping, gradually ending
up at 90% effort. Continue
to allow for increased
braking distance due to
reduced brake output.
3. Cool the brakes by lapping with minimal light braking
for six minutes. As with all high performance
brake systems, some amount
of brake squeal is normal.

Track Prep
—Camber Set
To achieve the maximum
camber setting for track use,
follow this procedure prior to
the final track alignment.
1. Remove the Upper Radiator Baffle and both
front shock tower braces.
2. Remove the strutrebound stop.

7. With the car on theground, reinstall the strut
rebound stop and torque it
to 25 Y(212 lb in).
8. With the car on the ground, reinstall the Upper
Radiator Baffle and both
front shock tower braces.
Torque the fasteners as
follows:
A. Front tower bracemounting bolts to 22 Y
(194 lb in).
B. Front strut top mount nuts to 22 Y(194 lb in). 9. Complete setting the track
alignment per the following
track alignment
specifications.

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect
vehicle handling and tire life,
and should be adjusted for
various types of tracks/
courses. Inspect the tires prior to every
track/course session. Track/
course driving will reduce the
tire tread life.
To maximize tire life, drive
800 km (500 mi) prior to
racetrack driving or complete
the minimum track running
that will increase the tire
pressures by 35 kPa (5 psi).
After this, immediately let the
tires cool to cold pressures.
Tire Inflation Pressure High
Speed
See Tire Pressure for
High-Speed Operation
0423.
Tire Inflation Pressure for
Track Driving
For driving on a race course,
if your vehicle is equipped with
255/35ZR18 (94Y) and
275/35ZR18 (99Y) tires, set
cold (stationary) tire pressures
to 30 psi. During track
sessions, set the pressures at
35 to 38 psi for hot tire
pressures. If pressures exceed
38 psi, bleed pressures down

1. Engine Coolant SurgeTank and Pressure Cap
2. Engine Cooling Fan (Out of View)
{Warning
An underhood electric fan
can start up even when the
engine is not running and
can cause injury. Keep
hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or
radiator hoses, or other
engine parts. They can be
very hot and can burn you.
Do not run the engine if
there is a leak; all coolant
could leak out. That could
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the
vehicle is filled with
DEX-COOL engine coolant.
See Maintenance Schedule
0469 and
Recommended Fluids and
Lubricants 0474.
The following explains the
cooling system and how to
check and add coolant when it
is low. If there is a problem
with engine overheating, see
Engine Overheating 0391.
What to Use
{Warning
Do not touch heater or
radiator hoses, or other
engine parts. They can be
very hot and can burn you.
Do not run the engine if
there is a leak; all coolant
could leak out. That could
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
Use a 50/50 mixture of clean
drinkable water and
DEX-COOL coolant. This
mixture:
.Gives freezing protection
down to −37 °C (−34 °F),
outside temperature.
.Gives boiling protection up
to 129 °C (265 °F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum
parts.
