check oil Oldsmobile Alero 2003 Owner's Manuals

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 it
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.
Oil Pressure Light
If you have a low engine
oil pressure problem, this
light will stay on after
you start your engine, or
come on and you will hear
a chime when you are
driving. This indicates that
your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it fixed immediately.
When the ignition is on but the engine is not running,
the light will come on as a test to show you it is working,
but the light will go out when the engine is running. If
it doesn’t come on with the ignition
on, you may have a
problem with the bulb. Have it fixed right away.
Don’t keer ing
if the oil pressi.. - is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice: Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Low Oil Level Light
LOW
OIL
If your vehicle is equipped
with a
3400 V6 engine,
then you
will have a LOW
OIL light in your
instrument panel cluster.
This light will come on briefly when you start your
vehicle.
If the light stays on after starting your vehicle, or comes
on and chimes while you are driving, your engine
oil
level should be checked.
Prior to checking the oil level, be sure your vehicle has
been shut
off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring it
to the proper level. See
Engine Oil on page 5-15.
The oil level monitoring system only checks oil level
during the brief period between when the key is on and
the engine is cranking. It does not monitor engine oil level
when the engine is running. Additionally, an oil level
check is only performed
if the engine has been turned off
for a considerable period of time allowing the oil normally
in circulation to drain back into the oil pan.
Change Engine Oil Light
CHANGE
OIL
The CHANGE OIL light
should come on briefly as
a bulb check when you
start the engine. If the light
' doesn't come on, have it

If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
To reset the CHANGE
OIL light, see Engine Oil on
page 5- 15.

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’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
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’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll 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 reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
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 inflated to the
recommended pressure?
Weather Forecasts: What’s 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?
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Don’t
let it happen to you!
If it does, your vehicle can leave
the road in
less than a second, and you could crash and
be injured.
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you find them quickly. If you’re trailering,
it’s a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See
Engine Overheating on
page
5-26.

California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label), it
is designed to operate on fuels that meet California
specifications.
If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see
Malfunction indicator Lamp on page 3-31 )
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. You should not have to add anything to your
fuel. Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines may be
available in your area to contribute to clean air.
General Motors recommends that you use these
gasolines, particularly
if they comply with the
specifications described earlier.
Notices Your vehicle was not designed for fuel that
contains methanol. Don’t use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage wouldn’t be covered under your
warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may
be affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer for
service.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to find. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel wouldn’t be
covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.

Checking Things Under
the HnDd
An electric fan under the hood can start up
and injure you even when the engine
is not
running. Keep hands, clothing and tools away
from any underhood electric fan.

other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop or
spill things that will burn onto a hot engine.

Engine Oil
LOW
OIL I
If the LOW OIL light
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
L
3400 V6 Engine Only
For more information, see
Low Oil Level Light on
page 3-35.
YOU should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It’s a good idea to check your 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.

Pull out 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.
3400 V6 Engine
The engine
oil dipstick handle is yellow. The dipstick on
the
2.2L L4 ECOTEC engine is located at the front of
the engine compartment. The dipstick on the
3400
V6 engine is located at the front of the engine, behind
the fan. See
Engine Compartment Overview on
page
5-12 for more information on location.
Turn
off the engine and give the oil several minutes to
drain back into the oil pan.
If you don’t, the oil
dipstick might not show the actual level.

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle. You
should look for and use only oils which have the API
Starburst symbol and which are also identified as
SAE 5W-30.
If you cannot find such SAE 5W-30 oils,
you can use an SAE 1OW-30 oil which has the API
Starburst symbol,
if it’s going to be 0°F (-18°C)
or above.
Do not use other viscosity grade oils, such as
SAE 1OW-40 or SAE 20W-50 under any conditions.
Nofice: Use only engine oil with the American
Petroleum Institute Certified For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below -20°F (-29”C), it is
recommended that you use either an SAE 5W-30
easier cold starting and better protection for your engine
at extremely low temperatures.

Engine Oil Additives
Don’t add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.
When to Change Engine Oil
(GM
Oil Life SystemTM)
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based
on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE
OIL light will come on. Change
your oil as soon as possible within the next two
times you stop for fuel. It is possible that,
if you are
driving under the best conditions, the oil life system may
not indicate that an oil change is necessary for over a
year. However, your engine oil and filter must be
changed at least once a year and at this time the system
regularly and keep it at the proper level.
%Est !x rcsd. It is a!sc irr?pcrtz??t ?e check ;‘QL!T Qi!
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
:vheneve: the ci! is changed.
