Driving Information
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 9-43. 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.

Caution (Continued)
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
When this procedure is performed
as instructed, it will not damage the
brakes. The brake pads will smoke
and produce an odor. The braking
force and pedal travel may increase.
After the procedure, the brake pads
may appear white at the rotor
contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation.
Brake Burnish Procedure (Z51 and
Z06 without Z07 Performance
Package)
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while
decelerating at 0.4 g. This is a medium brake application. Drive
for at least 1 km (0.6 mi)
between applying the brakes.
This first step may be skipped if
there are more than 320 km
(200 mi) on the brake pads.
2. Repeatedly apply the brakes from 100 km/h (60 mph) to
25 km/h (15 mph) while
decelerating at 0.8 g. This is a
hard brake application, without
activating the Antilock Brake
System (ABS). Drive for at least
1 km (0.6 mi) between stops.
Repeat until the brake pedal
travel starts to increase.
Depending on conditions, this
should take no longer than 25
brake applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake 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.

9-12 Driving and Operating
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Be alert on top of hills;
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C (32°
F) when freezing rain begins to fall,
resulting in even less traction. Avoid
driving on wet ice or in freezing rain
until roads can be treated with salt
or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Traction Control should be turned
on. SeeTraction Control/Electronic
Stability Control on page 9-37.
The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but apply the brakes sooner than when
on dry pavement. See
Antilock
Brake System (ABS) on page 9-34.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control on slippery
surfaces.
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program on page 13-5.
To get help and keep everyone in
the vehicle safe:
.Turn on the hazard warning
flashers.
