20 In Brief
If the vehicle is in a crash, the
sensing system may shut down the
high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
{Warning
Damage to the high voltage
battery or high voltage system
can create a risk of electric shock,
overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood,
fire, or other event, the vehicle
should be inspected as soon as
possible. Until the vehicle has
been inspected, store it outside at
least 15 m (50 ft) from any
structure or anything that can
burn. Ventilate the vehicle by
opening a window or a door.(Continued)
Warning (Continued)
Contact Customer Assistance as
soon as possible to determine
whether an inspection is needed.
SeeCustomer Assistance
Offices 0343.
See Battery - North America 0256
for important safety information.
If an airbag has inflated, see What
Will You See after an Airbag
Inflates? 068.
Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your
dealer if the high voltage battery
needs service.
See Battery - North America 0256.
Charging
This section explains the process
for charging the high voltage battery.
Do not allow the vehicle to remain in
temperature extremes for long
periods without being driven or
plugged in. It is recommended that the vehicle be plugged in when
temperatures are below 0 °C (32 °F)
and above 32 °C (90 °F) to
maximize high voltage battery life.
When using a 120-volt AC electrical
outlet, it will take approximately
13 hours to charge the vehicle with
the 12 amp AC current setting or
19 hours using the default 8 amp
AC current setting. When using a
240-volt charging station, it will take
approximately 4.5 hours to charge
the vehicle. Charge times will vary
with outside temperature. There are
three ways to program how the
vehicle is charged. See
Programmable Charging
0119.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking
sounds may be caused by the
electrical devices used while
charging.
While the charge cord is plugged
into the vehicle, the vehicle cannot
be driven.

inflate. The feature may also
activate, without airbag inflation,
after an event that exceeds a
predetermined threshold. You can
lock the doors, turn off the interior
lamps, and turn off the 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 you should attempt
to restart the engine after a crash
has occurred.
If an airbag inflates or the vehicle
has been in a crash, the sensing
system may shut down the high voltage system. When this occurs,
the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
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 0353
and Event Data
Recorders 0353.
. 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.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the overhead console
when the vehicle is started.

106 Instruments and Controls
Here are some things that 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 may have 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.
. 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.Driver Efficiency Gauge
This gauge appears on the left side
of the display in the Classic
Enhanced configuration.
This gauge is a guide to driving in
an efficient manner by keeping the
ball green and in the center of the
gauge. See
Driving for Better Energy
Efficiency 026.
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.
In the Modern display
configurations, the light ring in the
center of the display acts as an
efficiency gauge. It is green when
driving efficiently and turns yellow
when acceleration or braking is too
aggressive.

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 0108 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 (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 vehicle is in
Service Only Mode. See Power
Button 0175.
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.

not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0234. 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 vehicle is in Service
Only Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might 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.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 should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
If the light comes on and stays on,
there is a 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
MetricEnglish
This light comes on when the
parking brake is applied. If the light
continues flashing after the parking
brake is released, or while driving,
there is a problem with the Electric

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9807421) - 2017 - CRC - 11/18/15
112 Instruments and Controls
Parking Brake system or another
system. A message may also
display in the Driver Information
Center (DIC). SeeBrake System
Messages 0133.
If the light does not come on,
or remains flashing, see your dealer.
Service Electric Parking
Brake Light
If this light comes on and 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. See
Electric Parking Brake 0188. If a
message displays in the Driver
Information Center (DIC), see Brake
System Messages 0133.
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 0311.
Sport Mode Light
This light comes on when Sport
Mode is selected. See “Sport Mode”
in Driver Selected Operating Modes
0 181 for more information.
