Competitive Driving
Competitive driving may affect the vehicle warranty. See the warranty book before using the vehicle for competitive driving.
Notice: If you use your vehicle
for competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Be sure to check the oil level
often during competitive driving
and keep the level at or near the
upper mark that shows the proper
operating range on the engine oil
dipstick. For information on how
to add oil, see Engine Oil.
CTS–V Only: Be sure to check the oil level often during racing, track testing or other competitive driving and keep the level at or near the upper mark that shows the proper operating range on the engine oil dipstick.
For competitive driving, it is recommended that the brake fluid be replaced with a high performance brake fluid that has a dry boiling point greater than 279°C (534°F).
After conversion to the high performance brake fluid, follow the brake fluid service recommendations outlined by the fluid manufacturer. Do not use silicone or DOT–5 brake fluids.
HF V6 Engine Only: Be sure to check the oil level often during racing, track testing or other competitive driving and keep the level at or near 0.5 L (0.5 qt) above the upper mark that shows the proper operating range on the engine oil dipstick. For racing, track testing or other competitive driving an engine oil cooler must be installed.
