1998 PONTIAC GRAND AM check engine

If the Light Is On Steady Have you recently changed brands of fuel?
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. 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.
‘I ’
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 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.

Oil Pressure Warning Light
If you have a problem with
your engine’s oil pressure,
this light may
stay on after
you start your engine, or
come on and stay on when
you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated.
The engine could be low on oil, or could have some
other oil pressure problem. Have it fixed right away.
This light can come on briefly, which is normal and
doesn’t show a problem:
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.
0 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.
‘ A CAUTION: I
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

CHECK
OIL
Check Oil Light (If Equipped)
If your vehicle is equipped
with the
3 100 engine, this
light should come
on briefly
while you
are starting your
engine.
If the light does not
come on, have it repaired.
A
If the light comes on and stays on after starting your
vehicle, the 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 the 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 start.
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.
Passlock Warning Light
THEFT
SYS
This light will come on
briefly when you
turn the
key toward
START. The
light will stay on until the
engine starts.
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 dealer.
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.

Understanding Radio Reception
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 storms and power lines.
Try
reducing the treble to reduce this noise if you ever get it. \
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.
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.
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.
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 Electronics 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 dealer 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 or pulses 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.

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
Pontiac 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:

Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Oris it@ 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.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and
your
instruments frequently.
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.
4-24

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
e
e
Keep your vehicle in good shape. Check all fluid
levels and
also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down.
Shift to a lower gear when you go
down a steep or long hill.
-A CAUTION:
If you don’t shift down, your brakes could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going
down a
hill. You could crash. Shift down to let
your engine assist your brakes on a steep
~ downhill slope.
A CAUTION:
e
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. Drive in the highest
gear possible.
Stay
in your own lane when driving on two-lane
roads in hills
or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may
see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.
