Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, the engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. For information on how to
add oil, seeEngine Oil on page 5-17.
Z06 Only: Be sure to check the oil level often during
racing 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.
Except Z06: Be sure to check the oil level often
during racing or other competitive driving and keep
the level at or near 1 quart (1 L) above the upper
mark that shows the proper operating range on the
engine oil dipstick. After the competitive driving,
remove excess oil so that the level on the dipstick is
not above the upper mark that shows the proper
operating range.Vehicles with the Z51 performance package have
greaseable outer ends on both of the rear toe-links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. SeeScheduled
Maintenance on page 6-4andRecommended Fluids
and Lubricants on page 6-12. If you use the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer/retailer for lubrication
and make sure any needed repairs are made at
once. Proper procedures for performing these services
can be found in the service manual. SeeService
Publications Ordering Information on page 7-17.

in these conditions include:
Keep the vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
