A message may also display in the
Driver Information Center (DIC).
SeeAirbag System Messages on
page 5‑51 for more information.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See Passenger
Sensing System on page 3‑33
for important safety information.
The passenger airbag status
indicator is in the overhead console.
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF for several
seconds as a system check. Then, after several more seconds,
the status indicator will light either
ON or OFF to let you know the
status of the right front passenger
frontal airbag and the passenger
knee airbag.
If the word ON is lit on the
passenger airbag status indicator, it
means that the right front passenger
frontal airbag and the passenger
knee airbag are enabled and may
inflate.
If the word OFF is lit on the airbag
status indicator, it means that the
passenger sensing system has
turned off the right front passenger
frontal airbag and the passenger
knee airbag.

If, after several seconds, both
status indicator lights remain on,
or if there are no lights at all, there
may be a problem with the lights
or the passenger sensing system.
See your dealer for service.
{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 on page 5‑19 for more
information, including important
safety information.
Charging System Light
(12-Volt Battery)
The charging system light comes
on briefly when the vehicle is in
ON/RUN, as a check to show the
light is working.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is
on could drain the 12‐volt battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation
of the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping
to produce a cleaner environment.
This light comes on when the
vehicle is placed in Service Only
Mode, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
See Power Button on page 9‑18
for more information.

Black plate (24,1)Chevrolet Volt Owner Manual - 2011
5-24 Instruments and Controls
.The vehicle will not pass
this inspection if the OBD II
(On-Board Diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would
be considered not ready for
inspection. This can happen
if the 12‐volt battery has
recently been replaced or
if the 12‐volt battery has run
down. The diagnostic system
is designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system
consists of two hydraulic circuits.
If one circuit is not working, the
remaining circuit can still work to
stop the vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
This light comes on briefly when
the vehicle is turned on. If it does
not come on then, have it fixed so
it will be ready to warn if there is a
problem.If the light comes on and stays on,
there is a base brake problem.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.

Antilock Brake System
(ABS) Warning Light
This light should come on briefly
when the vehicle is in ON/RUN. If it
does not come on, have the vehicle
serviced by your dealer.
If the ABS warning light stays on
longer than a few seconds after the
vehicle is in ON/RUN, or comes
on and stays on while driving, try
resetting the system. To reset the
system:
1. While driving, pull over when it issafe to do so.
2. Place the vehicle in P (Park).
3. Turn the vehicle off.
4. Restart the vehicle. If the ABS warning light remains on
after resetting the system or comes
on again while driving, the vehicle
needs service. If the ABS warning
light is on, but the regular brake
system warning light is not on, the
antilock brakes are not working
properly, but the regular brakes are
still functioning. Have the vehicle
serviced right away. If both brake
lights are on, the vehicle does not
have antilock brakes, and there is
a problem with the regular brakes
as well. Have the vehicle towed for
service. See
Towing the Vehicle on
page 10‑84.

This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays
on while driving, there could be a
problem with the TCS/StabiliTrak
system and the vehicle might need
service. When this warning light is
on, the TCS/StabiliTrak system is
off and does not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays
on while driving, the vehicle may
have a problem with the cooling
system. Stop and turn off the
vehicle to avoid damage to the
engine. A warning chime sounds
when this light is on.
SeeEngine Overheating on
page 10‑23 for more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
in ON/RUN. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A message in the Driver Information
Center (DIC) may also display.
SeeTire Messages on page 5‑52
for more information. Stop as soon
as possible, and inflate the tires to
the pressure value shown on the
Tire and Loading Information Label.
See Tires on page 10‑48 for more
information.

When the Light Flashes First and
Then is On Steady
This indicates that there may be
a problem with the Tire Pressure
Monitor System. The light flashes
for about one minute and stays on
steady until the vehicle is in OFF.
This sequence repeats each time
the vehicle is in ON/RUN. SeeTire
Pressure Monitor System on
page 10‑55 for more information.
Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches
fire. Someone could be burned.
Check the oil as soon as possible
and have the vehicle serviced. Notice:
Lack of proper engine
oil maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
The oil pressure light should come
on briefly as the vehicle is started.
If it does not come on have the
vehicle serviced by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might
have some other system problem.
See your dealer.
Low Fuel Warning Light
The low fuel warning light comes on
briefly when the vehicle is started.
This light also comes on when the
