1993 PONTIAC GRAND-AM check engine

“Riding” the brakes wears them
out much faster. You would need
costly brake replacement
much
sooner than normal, and it also reduces fuel economy. 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 Bmkes (ABS)
Your Pontiac has an advanced electronic
braking system that will help prevent
skidding.
This light on the instrument panel will
go on when you start your vehicle.
When you
start your vehicle and begin
to drive away you may hear a
momentary motor or clicking noise
and
you may even notice that your brake
pedal moves a little while this is going
on. This is the ABS system testing itself.
If you have your foot on the brake
pedal,
this check won’t happen until the vehicle
goes about
4 mph (6 km/h) or until you
take your foot off the brake pedal.

On the Road
Unless you are the only driver, it is
good to share the driving task with
others. Limit
turns behind the wheel to
about
100 miles (160 km) or two hours
at a sitting. Then, either change drivers
or stop for some refreshment like coffee,
tea or
soft drinks and some. limbering
up. But do stop and move around. Eat
lightly along the way. Heavier meals
tend to make some people sleepy.
On two-lane highways or undivided
multilane highways that do not have
controlled access, you’ll want to watch
for some situations not usually found on
freeways. Examples are: stop signs and
signals, shopping centers with direct
access to the highway, no passing zones
and school zones, vehicles turning left
and right off the road, pedestrians,
cyclists, parked vehicles, and even
animals.
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.

Highway Hypnosis (CONI)
Keep your eyes moving. Scan the road
ahead and to the sides. Check your
rearview mirrors frequently and your
instruments from time to time. This
can help you avoid a fixed stare.
Wear good sunglasses in bright light.
Glare can cause drowsiness. But don’t
wear sunglasses at night. They will
drastically reduce your overall vision
at the very time you need all the
seeing power you have.
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.
As in any driving situation, keep pace
with traffic and allow adequate
following distances.
I CAUTION
d
Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain. 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.
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. Don’t make your brakes
do it
all. Shift to a lower gear when
you go
down a steep or long hill. That way,
you will slow down without excessive
use of your brakes.
A
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.

blanket around you.
If you have no
blankets or extra clothing, make body
insulators from newspapers, burlap
bags, rags, floor mats-anything you
can wrap around yourself or tuck
under your clothing to keep warm.
You can run the engine to keep warm,
but be careful.

cause deadly CO (carbon
monoxide) gas to get inside.
CO
could overcome you and kill you.
You can’t see it or smell it,
so you
might not know it was
in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that
is blocking your
exhaust pipe. And check around
again from time to time to be sure
snow doesn’t collect there.
Open a window just a little on the
side
of the vehicle that’s away from
the wind.
This will help keep CO out. Run your engine only as long as you
must. This saves fuel. When you
run
the engine, make it go
a little faster
than just idle. That is, push the
accelerator slightly. This uses less fuel
for the heat that you get and it keeps
the battery charged. You will need a
well-charged battery to restart the
vehicle and possibly for signaling later
on with your headlights.
Let the heater
run for a while.
Then, shut the engine off and close
the window almost all the way to
preserve the heat.
Start the engine
again and repeat this only when you
feel really uncomfortable from the
cold. But do it as little as possible.
Preserve the fuel as long as you can.

Turn Signals When Towing a ’Railer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a
turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other drivers you’re about to turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signal when
they are not. It’s important to check occasionally to be sure the trailer bulbs
are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer work well.
On a long uphill grade, use the highest
gear possible. If you cannot maintain
posted speeds, driving at a lower speed
may help avoid overheating your engine
and transaxle.
If you have a manual transaxle with
fifth
gear, it’s better not to use fifth gear. Just
drive in fourth gear (or, as you need to,
a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached,
on a hill. If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer can
be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet, or into gear
for a manual transaxle.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the chocks absorb the load.

Hill
1. Apply your regular brakes and hold
the pedal down while you:

Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of the chocks.
store the chocks.
Maintenance When Tmiler 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 overfiil),
engine oil, belts, cooling system, and
brake adjustment. Each
of these is
covered
in this manual, and the Ida
will help you find them quickly. If
you’re trailering, it’s a good idea to
review these sections before you
start
your trip.
Check periodically to see that all hitch
nuts and bolts are tight.

5. Check that the jumper cables don’t
have loose or missing insulation.
If
they do, you could get a shock. The
vehicles could be damaged, too.
Before you connect the cables, here are
some things you should know. Positive

(-) will go to negative (-) or a metal
engine part.
Don’t connect
(+) to (-) or you’ll get a
short that would damage the battery and
maybe other parts, too. Fans
or other moving engine
parts can injure you badly.
Keep your hands away from
moving parts once the engines are
