Bluetooth
For vehicles equipped with
Bluetooth capability, the system can
interact with many cell phones,
allowing:
.Placement and receipt of calls in
a hands-free mode.
.Sharing of the cell phone’s
address book or contact list with
the vehicle.
To minimize driver distraction,
before driving, and with the
vehicle parked:
.Become familiar with the
features of the cell phone.
Organize the phone book and
contact lists clearly and delete
duplicate or rarely used entries.
If possible, program speed dial
or other shortcuts.
.Review the controls and
operation of the infotainment
system.
.Pair cell phone(s) to the vehicle.
The system may not work with
all cell phones. See “Pairing”in

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.

9-6 Driving and Operating
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 quickly
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.
Racing or Other
Competitive Driving
Racing or competitive driving may
affect the vehicle warranty. See the
warranty book before using the
vehicle for racing or other
competitive driving.
Notice: If you use the 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, see Engine Oil on
page 10‑16. Z06, ZR1, and Grand Sport Coupe
manual transmission 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, ZR1, and Grand Sport
Coupe manual transmission:
Be sure to check the oil level
often during racing or other
competitive driving and keep the
level at or near 1 L (1 qt) 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.
Z06, ZR1, and Grand Sport Coupe
manual transmission Only: For
racing or competitive driving, it is
recommended that the brake fluid
be replaced with a high performance
brake fluid that has a dry boiling

9-8 Driving and Operating
Street High Performance Brake
Burnishing Procedure
Run this procedure in a safe
manner and in compliance with all
local and state ordinances/laws
regarding motor vehicle operation.
Run this procedure only on dry
pavement.
1. From a stop, accelerate asrapidly as possible without
activating traction control to a
speed of 97 kph (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, five times. This should take
about 10 minutes.
4. After completing the 50 stops, cool the brakes by driving for
8 km (5 mi) at 97 kph (60 mph). As with all high performance brake
systems, some amount of brake
squeal is normal.
Racing/Track Brake Burnish
Procedure
To prepare the ZR1 and Z06 with
Z07 Performance Package brake
system for track events and racing,
the Street High Performance Brake
Burnish as described previously
should be completed.
In addition to completing the Street
High Performance Brake Burnishing
Procedure, the following procedure
needs to be completed to make the
ZR1 and Z06 with Z07 Performance
Package brake system ready for
track events and racing.
This procedure should only be
run on a track and only on dry
pavement.
Notice:
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 and not too aggressive.
2. Laps 2 and 3 should be gradually driven faster and more
aggressive, while allowing for
reduced brake output and
increased stopping distance due
to brake fade.
3. Lap 4 as near to 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.

Driving and Operating 9-9
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.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.(Continued)
WARNING (Continued)
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.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑58.
.Turn off cruise control.

Black plate (11,1)Chevrolet Corvette Owner Manual - 2012
Driving and Operating 9-11
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.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.Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑35 improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
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.
