2010 PONTIAC G3 Owners Manual

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.

Engine Coolant Temperature Gage
United StatesCanada
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.
If the gage pointer moves into the red area, the engine
is too hot. It means that the engine coolant has
overheated.
If the vehicle has been operating under normal driving
conditions, pull off the road, stop the vehicle and turn off
the engine as soon as possible.
See Engine Overheating on page 6‑30.
Tire Pressure Light
For vehicles with the tire
pressure monitoring
system, this light comes
on briefly when the engine
is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
Stop and check the tires as soon as it is safe to do,
and inflate them to the proper pressure. See Tires
on
page 6‑50for more information.
4-28

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.
4-29

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.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this
inspection could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
.The vehicle will not pass this inspection if the
check engine light is on with the engine running,
or if the key is in the ON/RUN and the light is
not on.
.The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run
down. The diagnostic system is designed to
evaluate critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Light
If the vehicle has low
engine oil pressure, this
light will stay on after the
engine has been started,
or come on while driving.
This indicates that the engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have it fixed immediately by your
dealer/retailer.
4-31

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.

Fog Lamp Light
If the vehicle has this
feature, the fog lamps
light will come on when
the fog lamps are in use.
The light will go out when the fog lamps are turned off.
See Fog Lamps
on page 4‑12for more information.
Cruise Control Light
If the vehicle has cruise
control, this light comes
on whenever the cruise
control is set
The light will go out when the cruise control is turned
off. See Cruise Control
on page 4‑8for more
information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
See Headlamp High/Low-Beam Changer
on page 4‑5for more information.
Daytime Running Lamps (DRL)
Indicator Light
This light turns on
whenever the Daytime
Running Lamps are on.
See Daytime Running Lamps (DRL)
on page 4‑11for
more information.
4-33

Door Ajar Light
This light comes on and
stays on until all doors,
trunk and liftgate are
closed and completely
latched.
If the key is in the ignition while the driver's door is
open, a warning chime sounds.
Fuel Gage
United StatesCanada
The fuel gage tells about how much fuel is left when the
ignition is turned to ON/RUN.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
When the fuel tank is near empty, the low fuel warning
light comes on. There is still a little fuel left, but the
vehicle's fuel tank should be filled soon.
