{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers after the airbags
inflate. The feature may also
activate, without airbag inflation,
after an event that exceeds a
predetermined threshold. After turning the ignition off and then
on again, the fuel system will return
to normal operation; the doors can
be locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as
normal.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.
Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See Vehicle Data
Recording and Privacy 0314
and
Event Data Recorders 0314.
. Let only qualified technicians
work on the airbag system.
Improper service can mean that

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

Scroll to the desired features with
the thumbwheel, and press to toggle
them on or off.
Using the thumbwheel, except to
acknowledge an alert, will exit
Simplify mode.
The selected features will stay
hidden even after starting and
restarting the vehicle, unless
Simplify mode is manually canceled.
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer shows how far
the vehicle has been driven since
the trip odometer was last reset.The trip odometer is accessed and
reset through the Driver Information
Center (DIC). See
Driver
Information Center (DIC) 0108.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Shift lights will not appear until the
engine is warm.
Caution
If the engine is operated with the
rpm’s in the warning area at the
high end of the tachometer, the
vehicle could be damaged, and
the damage would not be covered
by the vehicle warranty. Do not
operate the engine with the rpm’s
in the warning area.
Fuel Gauge
When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the tank.
When the indicator nears empty, the
low fuel light comes on. There is still
a little fuel left, but the fuel tank
should be filled soon.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge indicated the tank was
half full, but it actually took a
little more or less than half the
tank's capacity to fill the tank.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12470550) - 2020 - CRC - 4/23/20
Instruments and Controls 99
.The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.
Engine Coolant
Temperature Gauge
This gauge shows the engine
coolant temperature.
If the gauge pointer moves into the
red zone, the engine is too hot.
This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as possible. See
Engine
Overheating 0230 for more
information.
Transmission
Temperature Gauge
This gauge will display when the
transmission is experiencing
abnormal temperatures.
As the transmission begins to
overheat, the gauge fills to the right.
The Transmission Temperature
Gauge monitors all aspects of the
transmission. Elevated transmission
temperatures may not be reflected
in the Transmission Fluid
Temperature cluster display gauge.
Messages will display to indicate the
severity of the overheating. As the
gauge fills up there will be a
reduction in vehicle performance. Once full, the transmission is
overheated and a message to stop
safely will display. Do not drive the
vehicle until the message clears.
See
Dual Clutch Transmission
0 171 for more information.
Seat Belt Reminders
Driver Seat Belt Reminder
Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.

safety information. The overhead
console has a passenger airbag
status indicator.
United States
Canada and Mexico
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the
symbols for on and off, for several
seconds as a system check. Then,
after several more seconds, the
status indicator will light either ON
or OFF, or the on or off symbol, to
let you know the status of the front
outboard passenger frontal airbag. If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag is
allowed to inflate.
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, if there
are no lights at all, or if the airbag
readiness light is on, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service right away.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right

away. SeeAirbag Readiness
Light 0100 for more information,
including important safety
information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.

102 Instruments and Controls
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode. SeeIgnition
Positions 0165.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
(Continued)
Caution (Continued)
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass
an Emissions Inspection/
Maintenance test. See
Accessories and Modifications
0211.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If the light continues to flash, find a
safe place to park. Turn the vehicle
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as
possible.

Instruments and Controls 103
If the light is on steady :A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless funnel
adapter, make sure that it has
been removed. See “Filling the
Tank with a Portable Gas Can”
under Filling the Tank 0205.
The diagnostic system can
detect if the adapter has been
left installed in the vehicle,
allowing fuel to evaporate into
the atmosphere. A few driving
trips with the adapter removed
may turn off the light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off. See
Recommended Fuel 0204.
If the light remains on, see your
dealer.Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
test equipment will likely connect to
the vehicle's Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. See Add-On
Electrical Equipment 0208. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running. .
The light does not come on
when the ignition is in
Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and may require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
