The system is automatically
disarmed when the vehicle is
started with a valid RKE transmitter
in the vehicle. The RKE transmitter
uses electronic coding that matches
an immobilizer control unit in the
vehicle and automatically disarms
the system. Only a correct
transmitter can be used to turn the
vehicle on.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
This light comes on briefly when the
vehicle is turned on. There is a
problem if the engine does not start
and this light stays on.
Turn the ignition off and try again.If the engine still does not start, and
the RKE transmitter appears
undamaged, try the other RKE
transmitter for the vehicle, or place
the RKE transmitter in the
transmitter slot. See
Remote
Keyless Entry (RKE) System
Operation on page 2-2. It may be
necessary to check the fuse. See
Electrical System Overload on
page 10-30. If the vehicle does
start, the first transmitter is bad or if
the vehicle still does not start the
vehicle needs service. See your
dealer.
Do not leave the key or device that
disarms or deactivates the vehicle
theft system in the vehicle.
Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

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).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is in ON/
RUN, or if the vehicle is placed
in Service Only Mode and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.

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 10-47.
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

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
fuel level is low. When fuel is added,
the light should go off. If it does not,
have the vehicle serviced.

Driving and Operating 9-33
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.

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 5-19. 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.
{Warning
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.

{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 both vehicles. 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
vehicle with the run-down
battery. 5. Locate the positive (+) and
negative (−) battery terminals on
the Volt. The access cover is
under the load floor access
cover in the rear cargo area.
Open the access covers for the
positive (+) terminal (1) and the
negative (−) terminal (2).
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 remote negative (−) terminal if
available, or a heavy, unpainted
metal engine part or a solid
engine ground on the vehicle
with the run-down battery. Do not connect positive (+) to
negative (−) or there will be a
short that may damage the
battery or other parts of the
vehicle. Do not connect the
negative (−) cable to the
negative (−) terminal on the
run-down battery because this
can cause sparks.
{Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.

11-8 Service and Maintenance
Brakes
Brakes stop the vehicle and are
crucial to safe driving.
.Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping.
.Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s systems
and components. See
Recommended Fluids and
Lubricants on page 11-10 for GM
approved fluids.
.Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
.Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled. Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed.
Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
.With a multi-point inspection,
your dealer can check the lamps
and note any concerns.
Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
.Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer
stopping distance, or uneven
tire wear.
.As part of the multi-point
inspection, trained dealer
technicians can visually inspect
the shocks and struts for signs
of leaking, blown seals,
or damage, and can advise
when service is needed.
Tires
Tires need to be properly inflated,
rotated, and balanced. Maintaining
the tires can save money and fuel,
and can reduce the risk of tire
failure.
.Signs that the tires need to be
replaced include three or more
visible treadwear indicators; cord
or fabric showing through the
