Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local
governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, always
keep your eyes on the road, hands
on the wheel, and mind on the drive.
.Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
.Watch the road. Do not read,
take notes, or look up
information on phones or other
electronic devices.
.Designate a front seat
passenger to handle potential
distractions.
.Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings.
Program all trip information into
any navigation device prior to
driving.
.Wait until the vehicle is parked
to retrieve items that have fallen
to the floor.
.Stop or park the vehicle to tend
to children.
.Keep pets in an appropriate
carrier or restraint.
.Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.

Driving and Operating 9-5
.Steering or Cornering Skid—
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other material on the road. Learn to
recognize warning clues
—such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
.Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.
Track Events and
Competitive Driving
Participating in track events or other
competitive driving without following
the instructions provided may affect
the vehicle warranty. See the
warranty manual before using the
vehicle for racing or other
competitive driving.
Refer to Competitive Driving Mode
on page 9-44. Be sure to follow all service
procedures before driving the
vehicle at track events or
competitively.
Engine Oil
{Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil on page 10-12.
{Caution
Not changing the engine oil to
15W-50 may cause engine
damage. Engine oil must be
changed to 15W-50 synthetic.
See
Capacities and Specifications
on page 12-2.

application. Drive for at least
1 km (0.6 mi) between
applications.
Street High Performance Brake
Burnishing Procedure (Z06 with
Z07 Performance Package)
1. From a stop, accelerate as rapidly as possible without
activating traction control to a
speed of 100 km/h (60 mph).
2. Use enough pedal force to completely stop the vehicle in
four to five seconds. If ABS
activates, braking is too hard.
3. Repeat Steps 1 and 2 –50
times. This should take about
10 minutes.
4. After completing the 50 stops, cool the brakes by driving for km
(5 mi) at 100 km/h (60 mph)
As with all high performance brake
systems, some amount of brake
squeal is normal. Racing/Track Brake Burnishing
Procedure (Z06 with Z07
Performance Package)
This procedure should only be run
on a track and only on dry
pavement.
{Caution
Brake pedal fade will occur during
this track burnish procedure and
can cause brake pedal travel and
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
1. Drive a normal first lap, not too aggressively.
2. Laps 2 and 3 should be gradually driven faster and more
aggressively, while allowing for
reduced brake output and
increased stopping distance due
to brake fade. 3. Drive Lap 4 near full speed,
while allowing for reduced brake
output and increased stopping
distance due to brake fade.
4. Laps 5 and 6 should be cool down laps.
5. Lap 7 should be normal driving or an easy out lap.Z07 Performance Package
The Z07 Performance Package has
an installed Stage 2 Aero Package,
which consists of a front splitter with
short end caps, rocker panel
extensions, and a rear spoiler.
Stage 3 Aero components are
delivered but not installed on the
vehicle. These are intended to be
installed for track use only. The
components include:
.Front splitter tall end caps that
replace the front splitter short
end caps.
.A center transparent wicker bill
for the rear spoiler.

{Warning
Changing the following track
settings could reduce tire traction
and could cause a crash. Do not
change the track settings
The track settings for the Z07
Performance Package with the
Stage 3 Aero Package are:
.The front splitter tall end caps
installed.
.The center transparent wicker
bill installed all the way up on
the rear spoiler.
.The Driver Mode Selector in
Track Mode.
Stingray with Performance
Package-Carbon Fiber (CFZ)
The Stingray with Performance
Package-Carbon Fiber (CFZ) has
an installed aero package which
consists of a front splitter with short
end caps, rocker panel extensions,
and a rear spoiler. A center transparent wicker bill for the rear
spoiler is delivered but not installed.
This is intended to be installed for
track use only.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
(Continued)
Warning (Continued)
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
