Black plate (25,1)Chevrolet Volt Owner Manual - 2012
Seats and Restraints 3-25
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.
You can lock the doors, and turn off
the interior lamps and hazard
warning flashers by using the
controls for those features.
{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 attempting to
restart the vehicle 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 on
page 13‑15 andEvent Data
Recorders on page 13‑16.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

in Extended Range Mode.
The number next to the indicator
displays an estimate of how far the
vehicle can be driven while in
this mode.
SeeExtended Range Mode on
page 9‑24.
Driver Efficiency Gauge
This gauge is a guide to driving in
an efficient manner by keeping the
ball green and in the center of the
gauge. The leaves stop spinning
when the vehicle stops or when the
ball travels away from the center of
the gauge.
See Driving for Better Energy
Efficiency on page 9‑2.
accel: If the ball turns yellow and
travels above the center of the
gauge, acceleration is too
aggressive to optimize efficiency. brake:
If the ball turns yellow and
travels below the center of the
gauge, braking is too aggressive to
optimize efficiency.
Total Vehicle Range
Total vehicle range is the remaining
distance the vehicle can be driven
combining the electric range and
fuel range.

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.
MetricEnglish
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.
Electric Parking Brake
Light
This status light comes on when the
parking brake is applied. If the light
flashes and stays on after the
parking brake is released, or while
driving, there is a problem with the
electric parking brake system.
If the light does not come on,
or remains flashing, see your dealer.
See
Electric Parking Brake on
page 9‑34 for more information.

Service Electric Parking
Brake Light
The Service Electric Parking Brake
light should come on briefly when
the vehicle is in ON/RUN. 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, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. SeeElectric
Parking Brake on page 9‑34 for
more information. If a message
displays in the Driver Information Center (DIC), see
Brake System
Messages on page 5‑48 for more
information.
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 is safe 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 10‑81.
