9-4 Driving and Operating
Control of a Vehicle
Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three‐fourths of a second.
In that time, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft), which could be a lot of
distance in an emergency.Helpful braking tips to keep in
mind include:
.Keep enough distance between
you and the vehicle in front
of you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. If the
engine stops, there will be some
power brake assist but it will be
used when the brake is applied.
Once the power assist is used up,
it can take longer to stop and the
brake pedal will be harder to push.
Steering
Magnetic Effort Steering
This system continuously adjusts
the effort felt when steering at all
vehicle speeds. It provides ease
when parking, yet a firm, solid feel
at highway speeds.
Hydraulic Power Steering
Your vehicle has hydraulic
power steering. It may require
maintenance. See Power Steering
Fluid Power Steering Fluid on
page 10‑36.
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but may required increased
effort. See your dealer if there is
a problem.

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

Black plate (7,1)Chevrolet Corvette Owner Manual - 2012
Driving and Operating 9-7
point greater than 279°C (534°F).
After conversion to the high
performance brake fluid,
follow the brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT‐5 brake fluids.
Z06, ZR1, and Grand Sport Coupe
manual transmission Only: For
racing or competitive driving, it is
recommended that the loading of
the vehicle be limited to the driver
only, with no other cargo, and that
tires be inflated to 180 kPa (26 psi)
for a maximum speed of 230 km/h
(143 mph).
If the vehicle is a Z06, ZR1,
or Grand Sport Coupe manual
transmission model, it has
greaseable outer ends on both of
the rear toe‐links. Under normal
use, lubrication should be performed
as described in the maintenanceschedule. See
Maintenance
Schedule on page 11‑3 and
Recommended Fluids and
Lubricants on page 11‑12. If using
the vehicle for racing, lubrication
should be performed at the end of
each racing day. See your dealer
for lubrication and make sure any
needed repairs are made at once.
Proper procedures for performing
these services can be found in
the service manual. See Service
Publications Ordering Information
on page 13‑17.
If the vehicle is used for racing or
other competitive driving, the rear
axle fluid temperatures may be
higher than would occur in normal
driving. We recommend that the
rear axle fluid be drained and
refilled with new fluid after every
24 hours of racing or competitive
driving. See Recommended Fluids
and Lubricants on page 11‑12 for
what fluid to use.ZR1 and Z06 with Z07
Performance Package Brake
Burnish Procedure
Notice: These procedures are
specific to the ZR1 and Z06
Performance Package with
ceramic brake rotors.
These procedures should not be
run on other Corvette models as
damage may result.
Notice: The new vehicle break‐in
period should be completed
before performing the brake
burnish procedure or damage
may occur to the powertrain/
engine. See New Vehicle Break-In
on page 9‑18.
When performed as instructed,
these procedures will not damage
the brakes. During the burnishing
procedure, the brake pads will
smoke and produce an odor. The
braking force and pedal travel may
increase. After the procedure is
complete, the brake pads may
appear white at the rotor contact.
