Service Electric Parking
Brake Light
This light should come on briefly
when the vehicle is turned on. If it
does not come on, have it fixed so it
will be ready to warn if there is a
problem.
If this light stays on or comes on
while driving there is a problem with
the Electric Parking Brake (EPB),
take the vehicle to a dealer as soon
as possible. In addition to the
parking brake, other safety functions
that utilize the EPB may also be
degraded. A message may also
display in the Driver Information
Center (DIC). SeeElectric Parking
Brake 0179.
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning. If both the ABS and the brake
system warning light are on, the
vehicle's antilock brakes are not
functioning and there is a problem
with the regular brakes. See your
dealer for service.
See
Brake System Warning Light
0 104.Traction Off Light
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
turns off.
The traction off light comes on when
the Traction Control System (TCS)
has been turned off by pressing and
releasing the TCS/Stability Control
button.

Air Vents
Use the tab on the air outlets to
change the direction of the airflow or
shut the outlet.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle.
. Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
. Keep the area around the base
of the instrument panel console
and air path under the seats
clear of objects to help circulate
the air inside of the vehicle more
effectively.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that are pulled into the vehicle.
Reductions in airflow, which may
occur more often in dusty areas,
indicate that the filter may need to
be replaced. See Maintenance
Schedule 0286.
Caution
Driving without a passenger
compartment air filter in place can
cause water and small particles,
like paper and leaves, to be
pulled into your climate control
system which may cause damage
to it. Make sure you always
replace the old filter with a
new one. The passenger compartment air
filter is located under the hood
between the battery and windshield.
See
Underhood Compartment
Overview 0214.
To check or replace the air filter:
1. Release the four clips for the left and right outer covers.

Driving and Operating 149
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
If the steering wheel is turned until it
reaches the maximum rotation and
is held at that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See your dealer if there is a
problem.
Dynamic Rack Travel
If equipped with Magnetic Ride
Control, Dynamic Rack Travel
(DRT) is a steering system feature
which enhances driving by providing
additional maximum steering wheel
rotation to allow a tighter turning
radius during low speed driving
conditions. If the vehicle speedincreases or if the suspension
encounters significant wheel travel,
such as a driveway, while at
maximum steering rotation, DRT
may gently push the steering back a
small amount to prevent the front
tires from contacting the vehicle.
This is normal operation. There is
no customer interface or display for
this feature. DRT is not available
when in Track Mode.
Curve Tips
.
Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable and
steady speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.
There are some situations when
steering around a problem may
be more effective than braking. .
Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
150 Driving and Operating
1. Ease off the accelerator andthen, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. 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
(Z51 Only)
Vehicles without Z51 package
should not be used for track events
and competitive driving.
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and
qualified drivers and should not
be used on public roads.
High-speed driving, aggressive
cornering, hard braking, and other
high-performance driving can be
dangerous. Improper driver inputs
for the conditions may result in (Continued)
