Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14622938) - 2021 - CRC - 2/10/21
Lighting 107
This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
To use the flash-to-pass feature, briefly pull
the turn signal lever toward you. The
high-beam indicator flashes to indicate to
the other driver that you intend to pass.
Daytime Running Lamps (DRL)
DRL can make it easier for others to see the
front of your vehicle during the day. DRL are
required on all vehicles first sold in Canada.
The DRL system makes the dedicated lamps
come on when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is in the AUTO.
.The light sensor determines it is daytime.When DRL are on, only the front lamps will
be on. The parking lamps, taillamps,
instrument panel lights, or other exterior
lamps will not be on when the DRL are
being used.
When it is dark enough outside, the front
lamps dim to parking lamps and the normal
low-beam headlamps turn on.
The regular headlamp system should be
turned on when needed.
To turn off the DRL, turn the exterior lamp
control to
O. The DRL will stay off until the
control is toggled again.
Automatic Headlamp System
When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps and parking lamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the sensor,
otherwise the headlamps will come on when
they are not needed.
The system may also turn on the headlamps
and parking lamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the DRL. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright
position. See Instrument Panel Illumination
Control 0109.

108 Lighting
When it is bright enough outside, the
headlamps and parking lamps will turn off
or may change to Daytime Running
Lamps (DRL).
The automatic headlamp system turns off
when the exterior lamp control is turned to
Oor the ignition is off.
To turn automatic headlamp system back
on, turn the band to

If the automatic headlamp system has the
headlamps turned on and you turn the
ignition off, the headlamps will turn off.
When the driver door is opened the
headlamps and parking lamps will illuminate
for a period of time.
The length of the delayed illumination
period can be changed. See “Exit Lighting”
under Vehicle Personalization 098.
The regular headlamp system should be
turned on when needed.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on and the exterior
lamp control is in AUTO, the headlamps,
parking lamps, and other exterior lamps will
come on. The time it takes for the lamps to turn on depends on the wiper speed. When
the wipers are turned off, the lamps turn
off. To disable, move the exterior lamp
control to
Oor;.
Hazard Warning Flashers
The hazard warning flashers warn others
that you have a problem. The button is on
the overhead console.
|:
Press to make the front and rear turn
signal lamps flash on and off. Press again to
turn the flashers off.
The hazard warning flashers work no matter
what mode the ignition is in, even if the
ignition is turned off. When the hazard warning flashers are on,
the turn signals will not work.
Turn and Lane-Change Signals
An arrow on the instrument cluster flashes
in the direction of the turn or lane change.
Move the lever all the way up or down to
signal a turn.
Raise or lower the lever until the arrow
starts to flash to signal a lane change. Hold
it there until the lane change is complete.
If the lever is briefly pressed and released,
the turn signal flashes three times. If more
flashes are desired, continue to hold the
lever.
The lever returns to its starting position
when it is released.

Lighting 109
If after signaling a turn or lane change the
arrows flash rapidly or do not come on, a
turn signal indicator light failure may have
occurred.
If a turn signal has failed, the lamp may
need to be replaced. See your dealer.
Turn Signal on Chime
A chime sounds if the turn signal has been
on for more than 1.2 km (0.75 mi) of driving.
If you need to leave the turn signal on for
more than 1.2 km (0.75 mi), turn off the
signal and then turn it back on.

188 Driving and Operating
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. SeeTraction
Control/Electronic Stability Control 0206.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0204.
.Allow greater following distance 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.
.Turn on Weather Mode. See Driver Mode
Control 0208.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 311. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.
.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 snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about 5 cm (2 in) on
the vehicle side 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
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0197.
To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running 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.

224 Driving and Operating
The instrument cluster may have a Park
Assist display with bars that show“distance
to object” and object location information
for RPA. As the object gets closer, more bars
light up and the bars change color from
yellow to amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear. When
an object is very close (<0.6 m (2 ft) in the
vehicle rear), five beeps will sound from
the rear.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red warning
triangle with a left or right pointing arrow
on the RVC screen to warn of traffic coming
from the left or right. This system detects
objects coming from up to 20 m (65 ft) from
the left or right side of the vehicle. When an object is detected, three beeps sound
from the left or right, depending on the
direction of the detected vehicle.
Turning the Features On or Off
To turn off the guidance lines:
1. On the infotainment system, touch SETTINGS, or turn the MENU knob to
highlight Settings and press MENU.
2. Select Rear Camera.
3. Select Guidance Lines and then select Off or On.
When the System Does Not Seem to
Work Properly
The RVC system may not work properly or
display a clear image if:
.It is dark.
.The sun or the beam of headlamps is
shining directly into the camera lens.
.Ice, snow, mud, or anything else builds
up on the camera lens. Clean the lens,
rinse it with water, and wipe it with a
soft cloth.
.The back of the vehicle is in a crash. The
position and mounting angle of the
camera can change or the camera can be affected. Be sure to have the camera and
its position and mounting angle checked
at your dealer.
Side Blind Zone Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers with
avoiding crashes that occur with moving
vehicles in the side blind zone (or spot)
areas. The SBZA warning display will light
up in the corresponding outside side mirror
and will flash if the turn signal is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists,
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
