2009 PONTIAC G3 ignition

Charging System Light
This light will come on briey 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.
SeeManual Transmission Operation on page 2-24for
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.

{CAUTION:
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 briey when the ignition is
turned to ON. If it does not come on then, have it xed
so it will be ready to warn if there is a problem.
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 oor. It may take longer to stop.
If the light is still on, have the vehicle towed for service.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey 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.
SeeBrake System Warning Light on page 3-28.
The ABS warning light will come on briey when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it xed 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 ashes, have the vehicle checked.
See “Hold Mode” underAutomatic Transmission
Operation on page 2-20for more information.
Engine Coolant Temperature Gage
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.
United StatesCanada
3-30

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.
SeeEngine Overheating on page 5-28.
Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briey 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
signicantly underinated.
Stop and check the tires as soon as it is safe to do,
and inate them to the proper pressure. SeeTires on
page 5-50for 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 ashes
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 5-58for 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:Modications 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.
Modications 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.
SeeAccessories and Modifications on page 5-3.
This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.

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 xed immediately by your
dealer/retailer.
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
xed right away.
If the vehicle comes to a hard stop, the light may
come on for a moment. This is normal.
3-34

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. SeeCruise Control on page 3-10for more
information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for more information.
Daytime Running Lamps (DRL)
Indicator Light
This light turns on
whenever the Daytime
Running Lamps are on.
SeeDaytime Running Lamps (DRL) on page 3-14for
more information.
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.
3-36

Fuel Gage
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 lled soon.
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 ll 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 ll 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. SeeFilling
the Tank on page 5-8.
