New Vehicle Break-In
Follow these recommended
guidelines during the first 2 414 km
(1,500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering.
. New brake linings also need a
break-in period. Avoid making
hard stops. This is
recommended every time brake
linings are replaced.
For the first 800 km (500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 rpm. .
Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
. Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
. Do not let the engine labor.
Never lug the engine. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
. If equipped with a dry sump
engine (Stingray with Z51,
Grand Sport, and Z06), the initial
oil and filter change must be
performed at 800 km (500 mi).
For the first 2 414 km (1,500 mi):
. Do not participate in track
events, sport driving schools,
or similar activities.
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal.
Front Air Dam
If equipped, the front air dam has
minimal ground clearance.
Under normal operation, the
components will occasionally
contact some road surfaces (speed
bumps, driveway ramps, etc.). This
can be heard inside the vehicle as a
scraping noise. This is normal and
does not indicate a problem.
Use care when approaching bumps
or objects on road surfaces and
avoid them when possible.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials.
Dealer-installed accessories may
also contain composite materials.
These parts and accessories may
include the splitter or rocker
extensions.
