2007 PONTIAC G5 fuel

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 274.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into
the atmosphere. A few driving trips with the cap
properly installed should turn the light off.
Did you just drive through a deep puddle of
water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 270. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this
as stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration.
(These conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.

Highbeam On Light
This light comes on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on
page 140.
Fuel Gage
Your fuel gage tells you
about how much fuel
you have left.Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage may
have indicated the tank was half full, but it
actually took a little more or less than half the
tank’s capacity to ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
For your fuel tank capacity, seeCapacities and
Specications on page 369.

Information Modes
q
(Information):Press this button to scroll
through the following vehicle information modes:
Outside Air Temperature and Odometer
Press the information button until the outside air
temperature and the odometer are displayed. This
mode shows the temperature outside of the vehicle
in either degrees Fahrenheit (°F) or degrees
Celsius (°C) and the total distance the vehicle has
been driven in either miles (mi) or kilometers (km).
The outside air temperature will appear on the left
side of the DIC display and the odometer will
appear on the right side of the display.
To change the DIC display to English or metric
units, see “UNITS” underDIC Vehicle
Personalization on page 179.
TRIP A or TRIP B
Press the information button until TRIP A or TRIP B
is displayed. These modes show the current
distance traveled since the last reset for each trip
odometer in either miles (mi) or kilometers (km).
Both odometers can be used at the same time.
Each trip odometer can be reset to zero separately
by pressing and holding the reset button for a
few seconds while the desired trip odometer
is displayed.
FUEL RANGE
Press the information button until FUEL RANGE is
displayed. This mode shows the remaining distance
you can drive without refueling in either miles (mi)
or kilometers (km). It is based on fuel economy and
the fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW
will display.
The fuel economy data used to determine fuel
range is an average of recent driving conditions.
As your driving conditions change, this data is
gradually updated. The FUEL RANGE mode
cannot be reset.
175

ECON (Economy)
Press the information button until ECON is
displayed. This mode shows how many miles per
gallon (mpg) or liters per 100 kilometers (L/100 km)
your vehicle is getting based on current and past
driving conditions.
Press and hold the reset button while ECON is
displayed to reset the average fuel economy.
Average fuel economy will then be calculated
starting from that point. If the average fuel economy
is not reset, it will be continually updated each time
you drive.
AV (Average) SPEED
Press the information button until AV SPEED is
displayed. This mode shows the vehicle’s average
speed in miles per hour (mph) or kilometers per
hour (km/h).
Press and hold the reset button while AV SPEED
is displayed to reset the average vehicle speed.
OIL LIFE
Press the information button until OIL LIFE is
displayed. The engine oil life system shows an
estimate of the oil’s remaining useful life. It will
show 100% when the system is reset after an oil
change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
SeeEngine Oil on page 279andScheduled
Maintenance on page 375.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life
System” underEngine Oil Life System on
page 282.
COOLANT
Press the information button until COOLANT is
displayed. This mode shows the temperature of the
engine coolant in either degrees Fahrenheit (°F) or
degrees Celsius (°C).

Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.Of course, you will nd experienced and able
service experts in GM dealerships all across
North America. They will be ready and willing to
help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?
