2007 CHEVROLET AVEO fuel cap

If the Light Is On Steady
You also 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 269.
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 266. 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, misfiring, 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 fix any mechanical or electrical
problems that may have developed.

Your fuel gage tells you about how much fuel you
have left when the ignition is turned to ON.
When the tank nears empty, the low fuel warning
light will come on. You still have a little fuel
left, but you should get more soon. SeeLow Fuel
Warning Light on page 172for more information.
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 fill 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 fill the tank.
•The indicator moves a little when you turn a
corner or speed up.
•The gage goes back to empty when you turn
off the ignition.
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 269.

If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
•Reducing vehicle speed
•Avoiding hard accelerations
•Avoiding steep uphill grades
If the light stops flashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to flash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still flashing, follow the
previous steps, and see your dealer for service as
soon as possible.

Certication Label
A vehicle specific Certification label is attached to
the center pillar (B-pillar), below the driver’s
door latch. This label tells you the gross weight
capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and
cargo. Never exceed the GVWR for your
vehicle, or the Gross Axle Weight Rating (GAWR)
for either the front or rear axle.
And, if you do have a heavy load, you should
spread it out. See “Steps for Determining Correct
Load Limit” earlier in this section.

The tethered fuel cap is located behind a hinged
fuel door on the passenger’s side of the vehicle.To remove the fuel cap, turn it slowly
counterclockwise. The fuel cap has a spring
in it; if the cap is released too soon, it will spring
back to the right.
{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop. Then
unscrew the cap all the way.

Be careful not to spill fuel. Do not top off or overfill
the tank and wait a few seconds after you have
finished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 349.
When replacing the fuel cap, turn it clockwise until
it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed.
This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp on
page 180.
{CAUTION:
If a re starts while you are refueling, do
not remove the nozzle. Shut off the ow
of fuel by shutting off the pump or by
notifying the station attendant. Leave the
area immediately.
Notice:If you need a new fuel cap, be sure
to get the right type. Your dealer can get
one for you. If you get the wrong type, it
may not t properly. This may cause your
malfunction indicator lamp to light and
may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp
on page 180.

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 276
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down
and check the level.
When to Add Engine Oil
If the oil is below the MIN (minimum) mark on the
dipstick, you need to add at least one quart/liter
of oil. But you must use the right kind. This section
explains what kind of oil to use. For engine oil
crankcase capacity, seeCapacities and
Specifications on page 368.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above
the upper mark that shows the proper
operating range, the engine could be damaged.
SeeEngine Compartment Overview on page 276
for the location of the engine oil fill cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range. Push the
dipstick all the way back in when you are through.
