1997 Oldsmobile Achieva check engine

If the Lipht Is On Steady
YOU may be ame 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. 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 (see
“Fuel” 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 retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Oil Pressure Warning Light
This light tells you if there
could be a problem with
your engine oil pressure.
This light can come on briefly, which is normal and
doesn’t show a problem:
0 As a bulb check, the light comes on when you turn
your key
to RUN and goes off when the engine is
started. If it doesn’t, be sure to have it fixed so it will
be there
to warn you.
For the four cylinder engine, when idling at a stop
sign, the light may blink on and then off. In addition,
if you make
a hard stop, the light may come on for
a moment.
But, when this light comes on and stays on, it means oil
isn’t going through your engine properly.
You could be
low on oil, or you might have some other oil problem.
Don’t keep driving
if the oil pressure 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.

Check Oil Light (If Equipped) Passlock Warning Light
CHECK
OIL
If you have a 3 100 engine,
this light should come on
briefly when you start the
engine.
If the light doesn’t
come on, have it repaired.
If the light comes on and
stays on after starting your
vehicle, your engine oil
level should be checked. SECURITY
This light will come on
briefly when you turn the
key toward the START
position. The light will stay
on until the engine starts.
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” in the Index.
NOTE:
A false CHECK OIL light may be generated
when parking on steep grades.
The
oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. 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.
If the light flashes, the Passlock system has entered a
tamper mode,
If the vehicle fails to start, see “Passlock”
in the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
system. Your vehicle will not be protected by Passlock,
and you should see your retailer.

The CRUISE light comes
on whenever you set your
cruise control.
CRUISE
Up Shift Light (Manual Transaxle)
This light comes on when
you need to shift to the next
higher gear. See “Manual
Transaxle” in the Index.
Low Washer Light

CHECK
GAGES
The LOW WASH FLUID
light will come on when
you turn on the ignition, and
the fluid container is less
than one-third full.
This light will come on
briefly when you are
starting the engine.
If it
stays on, or if it comes on
and stays
on while you are
driving, check your various
gages to see
if they are in
the warning zones.

Theft-Deterrent Feature After a Power
Loss” earlier in
this section.
Understanding Radio Reception
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably
and clearly.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and
go.
AM
The range for most
AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like stoms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful
to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to
it.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can add
what
you want. If you can, it’s very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle’s
engine, Delco radio or other systems, and even
damage them. Your vehicle’s systems may
interfere with the operation
of sound equipment
that
has been added improperly.
So, before adding sound equipment, check with
your retailer and
be sure to check Federal rules
covering mobile radio and telephone units.

Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This
is a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if
you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking. That
means better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.

If there’s a problem with the
anti-lock brake system, this
warning light will stay on. See “Anti-Lock Brake
System Warning Light” in
the Index.

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’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
Oldsmobile retail facilities 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 reservoir full?
Are all windows clean inside and outside?
Wil2er Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lumps: 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.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are
some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat
or rolling terrain.
