Instruments and Controls 5-19
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the vehicle. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
maintain a clean environment. The
malfunction indicator lamp 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. SeePower Button on
page 9-16 for more information.
If the malfunction indicator lamp
comes on, while the engine is in
ON/RUN, this indicates that the OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the dealer technician in
correctly diagnosing any
malfunction.
{Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
{Caution
Modifications made to the engine,
electric drive unit, exhaust, intake,
or fuel system of the vehicle or
the replacement of the original
tires with other than those of the
same Tire Performance Criteria
(TPC) can affect the vehicle
emission controls and can cause
this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10-2.

5-20 Instruments and Controls
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off and
wait at least 10 seconds before
driving the vehicle again. If the light
begins to flash again, follow the
previous steps and see your dealer
for service as soon as possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission control system
malfunction:
.Check that the fuel cap is fully
installed. The diagnostic system
can determine if the fuel cap has
been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up or
misfiring. These conditions might
go away once the engine is
warmed up. If one or more of these
conditions occurs, change the
fuel brand used. It may require
at least one full tank of the
proper fuel to turn the light off.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).

5-26 Instruments and Controls
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. See
Tire Messages on page 5-53. Stop
as soon as possible, and inflate the
tires to the pressure value shown on
the Tire and Loading Information
Label. SeeTires on page 10-40. 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. See
Tire
Pressure Monitor System on
page 10-48.
Engine Oil Pressure Light
{Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but if
the oil level is within the operating
range and the oil pressure is still
(Continued)
Caution (Continued)
low, have the vehicle serviced.
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.

Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and an Electronic
Stability Control system called
StabiliTrak. These systems help
limit wheel slip and assist the driver
in maintaining control, especially on
slippery road conditions.
TCS activates if it senses that any
of the drive wheels are slipping or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any of thevehicle wheel brakes to help assist
the driver in keeping the vehicle on
the intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck on
page 9-11 and“Turning the Systems
Off and On” later in this section.The indicator light for both systems
is in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak is
activated.
.Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.

.A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system. When the brake fluid falls to a low
level, the brake warning light comes
on. See
Brake System Warning
Light on page 5-21.
Checking Brake Fluid
Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview on
page 10-8.
With the vehicle not running for at
least one minute, the maximum fluid
level (1) is at the top of the reservoir body. With the vehicle running, the
fluid level should be in the proper
operating range (2) between the
MIN and MAX marks. If it is not,
have the brake hydraulic system
checked to see if there is a leak.
After work is done on the brake
hydraulic system, make sure the
level, with the vehicle running, is in
the proper operating range (2)
between the MIN and MAX marks.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11-10.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.

Caution (Continued)
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Park both vehicles close enough so that the jumper cables can
reach both vehicles' positive (+)
and negative (−) terminals. The
vehicles must not touch each
other. It could cause an
unwanted ground connection
that could damage both vehicles'
electrical systems.
Put both vehicles in P (Park) for
an automatic transmission or
electric drive unit. For a manual
transmission, place the vehicle
in Neutral and set the parking
brake.
{Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on the other vehicle. Turn off the radio, all
lamps, and accessories that are
not needed in both vehicles.
Unplug accessories from the
cigarette lighter or the accessory
power outlets. This avoids
sparks and helps save both
batteries and accessories.
4. Locate the positive (+) and negative (−) terminals on the
other vehicle.
5. Open the hood to locate the positive (+) and negative (−)
terminals on your Volt. Open the access cover for the remote
positive (+) terminal (1). The
remote negative (−) terminal (2)
for the Volt is a stud marked
GND (−) on the driver side of the
engine compartment.
6. Check that the jumper cables do not have loose or missing
insulation or a shock could result
and the vehicles could be
damaged.
Before connecting the jumper
cables, here are some basic
things to know. Positive (+)
jumper cable goes to positive (+)
battery terminal or a remote
positive (+) terminal if available.
Negative (−) jumper cable goes
to negative (−) battery terminal
or a remote negative (−) terminal
if available. Do not connect
positive (+) to negative (−) or
there will be a short that may
damage the battery and other
parts of the vehicle.
