For full details and information, see the vehicle’s Owner’s Manual.

2. SEASON THE BRAKES
BRAKE BURNISH PROCEDURE
Models: CT4-V Blackwing, CT5-V Blackwing
1. From a stop, accelerate as rapidly as possible without activating traction control to a speed of 60mph.
2. Using the G-Force Gauge in the HUD display, use enough pedal force to completely stop the vehicle in four to five seconds. If ABS activates,
braking is too hard.
3. Repeat the first two steps 20 consecutive times, this should take about five minutes.
4. After completing the 20 stops, cool the brakes by driving for 5mi at 60mph.
Please note: 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.
CONTINUED
BRAKE COOLING PREPARATION
Model: CT4-V Blackwing, CT5-V Blackwing
Prior to any track event, high speed driving event, or competitive driving, complete the following:
1. Ensure all the brake cooling parts are correctly secured and installed.
2. Inspect and replace and deflectors that have damage.
3. Inspect for blockage in the front brake cooling duct prior to every event.
4. Remove front tire deflector (if equipped).
If improved brake cooling is desired on Blackwings with cast-iron brakes (JGH) install the ball joint protector front shield, remove both upper
and lower rear rotor shields, and install the rear lower control arm cooling deflectors per the instruction in the brake cooling kit.
For full details on how to install, see the Owner’s Manual (pages 194-195).

1Do not use summer-only tires in winter conditions, as it would adversely affect vehicle safety, performance and durability. Use only GM-approved tire and wheel
combinations. Unapproved combinations may change the vehicle’s performance characteristics. For important tire and wheel information, go to https://my.chevrolet.
com/learnAbout/chevrolettires or see your dealer for details.
2Value will vary based on driving style, track, temperature and weather conditions.
Please note: The CT4-V Blackwing and CT5-V Blackwing are equipped with high performance summer-only tires. These tires have a special tread and compound that are optimized for
maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. It is recommended that winter tires
be installed on the vehicle if frequent driving at temperatures below approximately 40°F (5° C) or on ice- or snow-covered roads is expected.
