In Brief 23
Road Imperfections/Crown Effects
The vehicle's precise steering and
handling make it very responsive to
road surface feedback. A slight pull
may be felt in the steering
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts. This is
normal and the vehicle does not
require service.
Fuel (LT1 6.2L V8 Engine)
Premium Recommended Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with an octane rating as
low as 87 may be used, but it will
reduce performance and fuel
economy. SeeFuel0206.
Fuel (LT4 6.2L
Supercharged V8 Engine)
Premium Required Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with a 91 octane rating
may be used, but it will reduce
performance and fuel economy. See
Fuel 0206.
E85 or FlexFuel
No E85 or FlexFuel
Gasoline-ethanol fuel blends greater
than E15 (15% ethanol by volume),
such as E85, cannot be used in this
vehicle.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a Driver Information
Center (DIC) message when it is
necessary to change the engine oil
and filter. The oil life system should
be reset to 100% only following an
oil change.
Dry Sump Engine Break-In Oil
Change
If equipped with a dry sump engine,
the initial oil and filter change must
be performed at 800 km/500 mi.
Follow the engine oil life system for
every oil change thereafter.
Resetting the Oil Life System
1. Scroll through the DIC Info Pages menu until the
REMAINING OIL LIFE

174 Driving and Operating
Starting and
Operating
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.

have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.

vehicles, maintenance needs vary.
There may need to be more
frequent checks and services. The
Additional Required Services -
Normal are for vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits
0 170.
. Are driven on reasonable road
surfaces within legal driving
limits.
. Use the recommended fuel. See
