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.
4-25

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
Put on extra clothing or wrap a 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.
A CAUTION:
Snow can trap exhaust gases under your vehicle.
This can 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
is 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.
You can run the engine to keep warm, but be careful.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 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, belt, cooling system and brake adjustment.
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 these sections before you
start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When mailer Towing
Your cooling system may temporarily overheat during
severe operating conditions.
See “Engine Overheating’’
in the Index.
Towing A Trailer
(Except
3100 V6 Engine)
Your vehicle is neither designed nor intended to tow
a trailer.

i . Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
I NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want.
You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the
possibility
of the vehicles rolling, set the parking
brake firmly
on both vehicles involved in the jump
start procedure.
Put an automatic transaxle in
PARK (P) or a manual transaxle in NEUTRAL (N)
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter.
Turn off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
A CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

4. Open the hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
A CAUTION:
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 basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to a metal
engine part.
Using a match near
a battery can cause battery
gas to explode. People have been hurt doing this,
and
some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough
water. You don’t
need to add
water to the AC Delco Freedom@
battery
installed in every new GM vehicle. But
if a battery has ffler caps, be sure the right
amount
of fluid is there. If it is low, add water to
take care of that
first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get it
on you. If you accidentally get it in
your eyes
or on your skin, flush the place with
water and get medical help immediately. Don’t connect positive
(+) to negative (-) 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 engine is running.
