with JL9 or J55 brakes without Y4Q heavy
duty cooling system as damage may
result.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnishing procedure or damage may
occur to the powertrain/engine. SeeNew
Vehicle Break-In 0199.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the brake
pads will smoke and produce an odor. The
braking force and pedal travel may increase.
After the procedure is complete, the brake
pads may appear white at the rotor contact.
Run this procedure in a safe manner and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation. Run this procedure only on dry
pavement. Racing/Track Brake Burnishing Procedure
Caution
Brake 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. Apply the brakes 25 times starting at 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Repeatedly apply the brakes from 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application, without activating the
Antilock Brake System (ABS). Drive for at
least 1 km (0.6 mi) between stops. Repeat
until the brake pedal travel starts to
increase. Depending on conditions, this
should take no longer than 25 brake
applications. 3. Cool down: Drive at 100 km/h (60 mph)
for approximately 15 km (10 mi) without
using the brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applications.
Front Tire Deflectors, Lower Control Arm
Deflectors, and Disc Splash Shields (SS
except 1LE Only)
Before any racing event, remove the tire
deflectors in the front of the vehicle, and
replace the original deflector and splash
shield with the tall deflector and small
splash shield.
Caution
Race track driving with the original front
disc brake splash shield and front tire
deflector may result in brake pedal fade
due to high rotor temperatures.
To install the tall deflector and small splash
shield:

188 Driving and Operating
1. Remove the tire deflector.
2. Remove the front wheels.
3. Remove the calipers (3) from the knuckle.
4. Remove the brake rotors (2).5. Remove the original front splash
shields (1).
6. Remove the lower control arm deflectors.
7. Detach the wheel speed sensor harness clips from the lower control arm
deflector.
8. Install the small splash shields with two
screws (2) per corner. Torque to 9 Y
(80 lb inch).
Caution
Failure to reattach the wheel speed
sensor harness clips correctly could cause
interference with the wheel speed sensor,
and could damage the vehicle. 9. Re-attach the wheel speed sensor
harness clips by pushing them from the
bottom up, on the back tab. On the
original deflector, the push pins are
pushed from the top down.
10. Install the tall deflectors with three screws (1) per corner. Torque to 3.3 Y
(29 lb inch).
When installing new control arms,
torque the three screws to 4.5 Y
(40 lb inch).
11. Install the front rotors with one screw per corner. Torque to 9 Y(80 lb inch).
12. Apply liquid thread adhesive to the
caliper bolts (GM Part No. 9985399 –
Loctite 272 –Goodwrench 12345493).

Install the calipers with two screws (1)
per corner. Torque the caliper bolts to
200Y (148 lb ft).
13. Reinstall the front wheels using the wheel nut torque. See Capacities and
Specifications 0318.
Caution
After a track event, remove the tall
deflector and the small splash shield and
reinstall the original deflector and splash
shield. Failure to reinstall the original
parts may lead to corrosion, loss of
output, noise, premature brake pad and
rotor wear, reduced high-speed wet
braking, and damage to the tall deflector. 14. After a track event, repeat the steps to
reinstall the original lower control arm
deflectors and splash shields.
15. Reinstall the tire deflectors.
Custom Launch Control (If Equipped)
Custom Launch Control allows the following
parameters for Launch Control to be
modified:
.Launch RPM
.Slip Target (5%–15%)
.Surface Type
To adjust the Launch RPM, all of these
conditions must be met:
.The vehicle must be in Track Mode. See
“Track Mode” underDriver Mode Control
0 216.
.Performance Traction Management (PTM)
Mode must be enabled. For convertibles,
and SS equipped with 10-speed automatic,
Competitive Driving Mode must be
enabled. See Driver Mode Control 0216.
.The steering wheel must be straight.
.The driver door must be closed.
.The transmission must be in a gear other
than R (Reverse). It will work in P (Park)
or N (Neutral).
.The parking brake must not be engaged. For more information on Competitive Driving
Mode, see

blades. Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may cause
wiper streaking.
Replace the wiper blades if they are worn or
damaged. Damage can be caused by
extreme dusty conditions, sand, salt, heat,
sun, snow, and ice.
Weatherstrips
Apply weatherstrip lubricant on
weatherstrips to make them last longer, seal
better, and not stick or squeak. Lubricate
weatherstrips at least once a year. Hot, dry
climates may require more frequent
application. Black marks from rubber
material on painted surfaces can be removed
by rubbing with a clean cloth. See
Recommended Fluids and Lubricants0313.
Tires
Use a stiff brush with tire cleaner to clean
the tires.
Caution
Using petroleum-based tire dressing
products on the vehicle may damage the
paint finish and/or tires. When applying a

Caution (Continued)
tire dressing, always wipe off any
overspray from all painted surfaces on
the vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with mild soap and
water to clean the wheels. After rinsing
thoroughly with clean water, dry with a
soft, clean towel. A wax may then be
applied.
Caution
Chrome wheels and chrome wheel trim
may be damaged if the vehicle is not
washed after driving on roads that have
been sprayed with magnesium chloride or
calcium chloride. These are used on roads
for conditions such as dust and ice.
Always wash the chrome with soap and
water after exposure.
Caution
To avoid surface damage on wheels and
wheel trim, do not use strong soaps,
chemicals, abrasive polishes, cleaners,

or brushes. Use only GM approved
cleaners. Do not drive the vehicle through
an automatic car wash that uses silicon
carbide tire/wheel cleaning brushes.
Damage could occur and the repairs
would not be covered by the vehicle
warranty.
Brake System
Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear
and rotors for surface condition. Inspect
drum brake linings/shoes for wear or cracks.
Inspect all other brake parts.
Steering, Suspension, and Chassis
Components
Visually inspect steering, suspension, and
chassis components for damaged, loose,
or missing parts or signs of wear at least
once a year.
Inspect power steering for proper
attachment, connections, binding, leaks,
cracks, chafing, etc.
