2001 Oldsmobile Aurora Fuel tank

2-74
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
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 you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
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. See ªFilling Your Tankº in the Index. 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.

2-75
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of air are sucked into the fuel line causing a misfire.
The system can detect this. Adding fuel should correct
this condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. It will take a
few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See ªFuelº in the Index. 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,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the CHECK
ENGINE light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(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 you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center
to prepare the vehicle for inspection.

2-77 Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
This light will come on for a few seconds when you turn
the ignition key to RUN to let you know it is working.
Fuel Gage
United States CanadaWhen the ignition is on, your fuel gage tells you about
how much fuel you have left.
When you have less than 3.0 gallons (11.3 L) of
fuel remaining, the DIC message LOW FUEL will
be displayed and a chime will sound. You need to get
more fuel right away.
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 gage moves a little when you turn a corner
or speed up.

The tank is not necessarily empty when the gage
reads empty. There is a reserve of about 1.5 gallons
(5.6 L) in the tank. You should still get more fuel
as soon as possible.

2-80 Fuel
Press SELECT down arrow while in the FUEL mode
to see how much fuel has been used and the fuel
range functions.
Fuel Used
While in the FUEL USED function the display will
show a reading such as:
FUEL USED: 10.4 GAL or FUEL USED: 39.4 L
To learn how much fuel will be used from a specific
starting point, first enter the FUEL USED mode to
display FUEL USED, then press and hold the
RESET button for three seconds.
Don't confuse fuel used with the amount of fuel in
your tank.
Fuel Range
The FUEL RANGE mode calculates the remaining
distance you can drive without refueling. It's based
on fuel economy and the fuel remaining in the tank.
The display will show a reading such as:
FUEL RANGE: 235 MI or FUEL RANGE: 378 KMIf the range is less than 50 miles (80 km), the display
will read LOW FUEL RANGE.
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.
Fuel range cannot be reset.
Fuel Economy
Pressing the SELECT down arrow while in the ECON
mode displays average fuel economy and instantaneous fuel
economy calculated for your specific driving conditions.
Average fuel economy will be shown in a reading such as:
25.2 AVG MI/GAL or 9.3 AVG L/100 KM
Instantaneous fuel economy will be shown in a reading
such as:
28 INST MI/GAL or 8.4 INST L/100 KM
The average fuel economy is viewed as a long
-term
approximation of your overall driving conditions.
If you press and hold RESET for three seconds in
this mode while you're driving, the system will begin
figuring average fuel economy from that point in time.
Instantaneous fuel economy cannot be reset.

Filling Your Tank
CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don't smoke if you're near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.
The cap is behind a hinged door on the driver's side of
the vehicle.

6-8
While refueling, hang the tethered cap from the hook on
the fuel door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if you let
go of the cap too soon, it will spring back to the right.
CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any ªhissº noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See ªCleaning the
Outside of Your Vehicleº in the Index.

6-9
When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. 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. See ªMalfunction Indicator Lampº in
the Index.
The CHECK GAS CAP DIC message will come on if
the fuel cap is not properly reinstalled.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you. If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See ªMalfunction Indicator Lampº in
the Index.

6-40
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to your dealer for service. However, it
is possible for you to re
-aim your headlamps as
described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on the
driver's seat.

Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming devices are under the hood near
the headlamps.
