2010 PONTIAC G3 service

This light comes on
when the vehicle is
started, and it will flash
for a few seconds. When
the light goes out this
indicates the system is
functioning properly.
If the airbag readiness light stays on or comes on while
driving, the airbag system may not work properly. Have
the vehicle serviced right away.
{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 the passenger sensing system. See
Passenger Sensing Systemon page 2‑65for important
safety information. The vehicle has a passenger airbag
status indicator near the clock, located in the center of
the instrument panel.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light PASSENGER AIRBAG ON and
PASSENGER AIRBAG OFF or the symbol for on and
off, for several seconds as a system check. Then, after
several more seconds, the status indicator will light
either PASSENGER AIRBAG ON or PASSENGER
AIRBAG OFF, or either the on or off symbol, to let you
know the status of the right front passenger frontal and
seat-mounted side impact airbag (if equipped).
4-24

If the words PASSENGER AIRBAG ON or the on
symbol is lit on the passenger airbag status indicator, it
means that the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped) is
enabled (may inflate).
If the words PASSENGER AIRBAG OFF or the off
symbol is lit on the passenger airbag status indicator, it
means that the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped).
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/retailer 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 4‑23
for more information, including important safety
information.
Charging System Light
This light will come on briefly when the ignition is turned
on, and the engine is not running, as a check to show it
is working.
It should go out when the engine is started. If it stays
on, or comes on while driving, there may have a
problem with the electrical charging system. Have it
checked by your dealer/retailer. Driving while this light is
on could drain the battery. If a short distance must be
driven with the light on, turn off all accessories, such as
the radio and air conditioner to help reduce the drain on
the battery.

Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
See Manual Transmission Operation
on page 3‑26for
more information.
Brake System Warning Light
The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking, both parts
need to work.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
United StatesCanada
{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.
This light should come on briefly when the ignition is
turned to ON. If it does not come on then, have it fixed
so it will be ready to warn if there is a problem.
4-26

When the ignition is on, the brake system warning light
will also come on when the parking brake is set. The
light will stay on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while driving, carefully pull off the
road and stop. The pedal may be harder to push or may
go closer to the floor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5‑25.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again while driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning light
is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system
warning light is also on, the antilock brakes will not
work and there is a problem with the regular brakes.
See
Brake System Warning Light on page 4‑26.
The ABS warning light will come on briefly when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it fixed so it will be ready
to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes
on when the hold mode
is active.
If the HOLD mode light flashes, have the vehicle
checked. See “Hold Mode”underAutomatic
Transmission Operation
on page 3‑22for 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 a
minute and then stays on steady for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System
on
page 6‑58for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It makes sure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light comes on when
the ignition is on, but the
engine is not running, as
a check to show it is
working. If it does not,
have the vehicle serviced
by your dealer/retailer. If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Heeding the light can prevent
more serious damage to the vehicle. This system
assists the service technician in correctly diagnosing
any malfunction.
Notice:
If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle's 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.
Notice: Modifications made to the engine,
transmission, 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's 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 6‑3.

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, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the
previous steps and see your dealer/retailer 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.
An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑8. 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.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and may cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. 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 will require at least one full
tank of the proper fuel to turn the light off.
See
Gasoline Octane on page 6‑6.
If none of the above have made the light turn off, have
your dealer/retailer check the vehicle. The dealer/
retailer has the proper test equipment and diagnostic
tools to fix any mechanical or electrical problems that
might have developed.

The oil light could also come on in three other
situations:
.When the ignition is on but the engine is not
running, the light will come on as a test to show it
is working. It goes out when the ignition is turned
on. If it does not come on with the ignition on,
there may be a problem with the fuse or bulb.
Have it fixed right away.
.If the vehicle comes to a hard stop, the light may
come on for a moment. This is normal.
{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 in this manual for changing
engine oil.
Change Engine Oil Light
The vehicle may have an engine oil life system that
indicates when the oil needs to be changed.
When the change engine oil light comes on, it means
that the engine oil needs to be changed.
Once the engine oil has been changed, the engine oil
life system must be reset. After reset, the change
engine oil light goes out.
See Engine Oil Life System
on page 6‑18,Scheduled
Maintenanceon page 7‑3and Engine Oilon
page 6‑15for more information.

Here are four things that some owners ask about. None
of these show a problem with the fuel gage:
.At the service station, the gas pump shuts off
before the vehicle's fuel gage reads full.
.It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may
have indicated the fuel tank was half full, but it
actually took a little more or less than half the
tank's capacity to fill the tank.
.The indicator moves a little when the vehicle turns
a corner or accelerates.
.The fuel gage indicator goes back to empty when
the ignition is turned off.
Low Fuel Warning Light
This light comes on when
the vehicle is low on fuel.
The low fuel warning light comes on when there is
approximately 1.7 gallons (6.0 liters) of fuel remaining in
the tank.
To turn the light off, add fuel to the fuel tank. See Filling
the Tank on page 6‑8.
