Steering
Power Steering
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Magnetic Speed Variable Assist
Steering System
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.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight. Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until out of the curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. These
problems can be avoided by braking
—if you can stop
in time. But sometimes you cannot stop in time because
there is no room. That is the time for evasive
action —steering around the problem.
The vehicle can perform very well in emergencies
like these. First apply the brakes. See Braking
on
page 5‑4. It is better to remove as much speed as
possible from a collision. Then steer around the
problem, to the left or right depending on the
space available.
5-16

If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.
While driving on a surface with reduced traction, try
your best 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. You may not realize the surface is slippery
until the vehicle is skidding. 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.
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 6‑19.
Z06, ZR1, and Grand Sport 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: Be sure to check
the oil level often during racing or other competitive
driving and keep the level at or near 1 L (1 quart)
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 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 point greater than 279°C (534°F).
5-19

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.
If the vehicle is a Z06, ZR1, or Grand Sport model, it
has greaseable outer ends on both of the rear toe‐links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. See Scheduled
Maintenance
on page 7‑3and Recommended Fluids
and Lubricantson page 7‑10. If using the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer/retailer 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 8‑16.
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 7‑10for what fluid to use.
ZR1 Brake Burnish Procedure
Notice: These procedures are specific to the ZR1
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 3‑21.
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.

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your 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 your 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. See Tireson page 6‑62.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
.Windshield Washer Fluid: Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?
5-23

Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a safe
place to park your vehicle and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan the road ahead
and to the sides.
.Check the rearview mirror and vehicle
instruments often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving in
these conditions include:
.Keep the vehicle serviced and in good shape.
.Check all fluid levels and brakes, tires, cooling
system, and transmission.
.Going down steep or long hills, shift to a
lower gear.
{WARNING:
If you do not shift down, the brakes 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. Shift down to let the engine
assist the brakes on a steep downhill slope.
5-24

{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.
.Top of hills: Be alert —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 Traction Control System (TCS)
on page 5‑6improves the ability to accelerate on slippery roads,
but slow down and adjust your driving to the road
conditions. The Active Handling System
on page 5‑8might also activate. When driving through deep snow,
turn off the traction control system to help maintain
vehicle motion at lower speeds.
5-25

TheAntilock Brake System (ABS)on page 5‑5improves vehicle stability during hard stops on a
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, if equipped, on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a serious situation.
Stay with the vehicle unless there is help nearby.
If possible, use the Roadside Assistance Program
on
page 8‑7. To get help and keep everyone in the
vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
.Check again from time to time to be sure
snow does not collect there.
.Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting.
See Climate Control System in the Index.

WARNING: (Continued)
For more information about carbon monoxide, see
Engine Exhaust on page 3‑37.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine
off and close the window most of the way to save heat.
Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator pedal
slightly so the engine runs faster than the idle speed.
This keeps the battery charged to restart the vehicle
and to signal for help with the headlamps. Do this as
little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow.
See Rocking Your Vehicle to Get It Out on page 5‑28.
If the vehicle has a traction system, it can often help
to free a stuck vehicle. Refer to the vehicle's traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the vehicle's tires spin at high speed, they
can explode, and you or others could be injured.
The vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
see Tire Chains on page 6‑84.
