Voltmeter
You can read battery voltage on your
voltmeter.
If it reads less than 11 volts or
more than
16 volts while your engine is
running, and it stays there, you may have
a problem with the electrical charging
system. Have it checked right away.
Driving with the voltmeter reading in a
warning zone could drain your battery.
If you idle your engine for a while, the
voltmeter reading might move into the
yellow zone.
If the reading stays in the
yellow zone while you are driving, you
may have a problem with the electrical
charging system. Have it checked. While
the voltmeter reads in the yellow zone,
your battery may not be able
to power
certain electrical accessories, like
ABS.

:If this happens, your “ABS INOP’ light
will come on. See “Anti-Lock Brake
System Warning Light” in this
part.)
[f you must drive a short distance with the
voltmeter reading in a warning zone, turn
~ff all your accessories, including your
:omfort control and audio systems.
Malfunction Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on when
the ignition is on, but the engine is not
running, as a check to show you it is
working.
If it doesnot come on at all,
have it fixed right away.
If it stays on, or
it comes on while you are driving, the
computer is indicating that you have a
problem. You should take your vehicle in
for service soon.

NOTICE:
If you keep driving your vehicle with
this light on, after a while the emis-
sion controls won’t work as well,
your fuel economy won’t be as good
and your engine may not run as
smoothly. This could lead to costly
repairs not covered by your warranty.

hgine Oil Pressure Gage
‘his gage tells you if there could be a
roblem with your engine oil pressure.
’he engine oil pressure gage shows the
ngine oil pressure in psi (pounds per
quare inch)
in the U.S., or kPa
cilopascals) in Canada, when the engine
; running. Oil pressure should be 20 to
0 psi (140 to 550 kPa). It may vary with
ngine speed, outside temperature and
il viscosity, but readings above the red
rea show the normal operating range.
leadings in the red area tell you that the
ngine is low on oil, or that you might
ave some other oil problem. See “Engint

Comfort Controls and Audio Systems
I‘
Air Conditioner Controls (OPTIoN)
The air conditioning system uses the same
controls
as the heating system, except that
the air control knob has two extra
settings, described below. For
an
explanation of all the controls, see
“Heater Controls” earlier in this part.
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting recirculates most of the air inside
your vehicle. If it is used for long periods
of time, the air may become
dry. This
setting directs air through the upper air
vents.
. . .lo6
A/C: Use for normal cooling on hot days
This setting cools outside air and directs
through the upper air vents.
The air conditioner comtxessor oDerates
in
“MAX,” “NC” and ii VJ , ,% and
9 when the outside temperature is
a6&e freezing. When the air conditioner
is on, you may sometimes notice slight
changes in your vehicle’s engine speed
and power. This is normal because the
system is designed
to cycle the
compressor on and
off to keep the desirec
cooling and help fuel economy.
Cooling
The air conditioner works best
if you keep
your windows closed. On very hot days,
open the windows just long enough for
the hot air to escape.
1. Turn the air control knob to “NC” for
normal cooling. For faster cooling
move the knob to
‘“AX.”
2. Turn the temperature control knob to
3. Turn the fan control knob to the right. a comfortable setting.

Your Driving and the Road
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 thnk 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
clohng 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:
Windshield Washer Fluid: Is the
reservoir full? Are all windows clean
inside and outside?
. . .I40
Wiper Blades: Are they m good
shape?
0 Fuel, Engine Oil, Other Fluids:
Have you checked all levels?
0 Lights: Are they all workmg? Are the
lenses clean?
0 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?
Maps: Do you have up-to-date
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:
0
0
0 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.

Your Driving and the Road
You can run the engine to keep warm, but
be careful.
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 awhile. 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. To help keep warm, you can get out
of the vehicle and do some fairly vigorous
exercises every half hour or
so until help
comes.
Towing a Trailer
. . .I44
ProCarManuals.com

NOTICE:
Pulling a trailer improperly can
damage your vehicle and result in
costly repairs not covered by your
warranty.
To pull a trailer correctly,
follow the advice in this section, and
see your Pontiac dealer for important
information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer if it is
equipped with the proper trailer towing
equipment. To identify what the vehicle
trailering capacity is for your vehicle, you
should read the information in “Weight
of the Trailer” that appears later in this
section. But trailering is different than just
driving your vehicle by itself. Trailering
means changes
in handling, durability,
and fuel economy. Successful, safe
trailering takes correct equipment, and
it has to be used properly.
That’s the reason for this section. In it are
many time-tested, important trailering
tips and safety rules. Many of these are
important for your safety and that of your
passengers.
So please read this section
carefully before you pull a trailer. Load-pulling components such
as the
engine, transmission, rear axle, wheel
assemblies, and tires are forced to work
harder against the drag of the added
weight, The engine is required to operate
at relatively higher speeds and under
greater loads, generating extra heat.
What’s more, the trailer adds considerably
to wind resistance, increasing the pulling
requirements.
If You Do Decide to Pull a Trailer
If you do, here are some important points.
0 There are many different laws,
including speed limit restrictions,
having to do with trailering. Make
sure your rig will be legal, not only
where you live but also where you’ll
be driving.
A good source for this
information can be state or provincial
police.
0 Consider using a sway control. You
can ask a hitch dealer about sway
controls.
0 Don’t tow a trailer at all during the
first 1,000 miles (1 600 km) your
new vehicle is driven. Your engine,
axle or other parts could be damaged.
(800 km) that you tow a trailer, don’t
drive over
50 mph (SO h/h) and don’t
make starts at full throttle. This heips
your engine and other parts of your
vehicle wear in at the heavier loads.
Obey speed limit restrictions when
towing a trailer. Don’t drive faster
than the maximum posted speed for
trailers (or no more than
55 mph
(90 km/h)) to save wear on your
vehicle’s parts.
Three important considerations have to do
with weight:
., )I
Weight of the .Trailer $:
How heavy can a trailer safelyabe?
It should never weigh more th&
1,500 pounds (680 kg) under nQrmal
driving conditions. It should n&er
weigh more than
1,000 pounds
(450 kg) when driven on long grades
at high ambient temperatures. But
even that can be too heavy.

H Fuel
The 8th digit of your Vehicle
Identification Number (VIN) shows
the code letter for your engine.
You will
find the VIN at the top left of your
instrument panel. (See “Vehicle
Identification Number” in the Index.)
3.4L L32 (Code S)
Use regular unleaded gasoline rated at 87 octane or higher. It should meet
specifications ASTM D4814 in the
U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have
to add anything to: the
fuel.
In the U.S. and Canada, it’s easy to be sure you get the right kind of giisoline
(unleaded). You’ll see “UNLEADED”
right on the pump. And only unleaded nozzles will fit into your vehicle’s filler
neck.
’ Be sure the posted octane is at least 87.
If the octane is less than 87, you may get
a heavy knochng noise when
you drive.
If it’s bad enough, it can damage your
1 engine. If
you’re using fuel rated at 87 octane or
higher and you still hear heavy knoclung,
your engine needs service. But don’t
worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal, and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
5.7L LT1 (Code P)
Use premium unleaded gasoline rated at
91 octane or higher. You may use middle
grade or regular unleaded gasolines, but
your vehicle may not accelerate as well.
The gasoline you use should meet
specifications
ASTM D4814 in the U.S.
and
CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything to the
fuel.
In the
U.S. and Canada, it’s easy to be
sure you get the right lund of gasoline
(unleaded). You’ll see “UNLEADED”
right on the pump. And only unleaded nozzles will fit into your vehicle’s filler
neck. Be sure
the posted octane for premium
is
at least 91 (at least 89 for middle grade
and 87 for regular).
If the octane is less
than 87, you may get a heavy knocking
noise when you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at
91 octane or
higher and you still hear heavy knocking,
your engine needs service. But don’t
worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
All Engines
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.”
Fuel that is no more than
15% MTBB is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more
than 10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.

ProCarManuals.com

Service and Appearance Care
NOTICE:
Fuel that is more than 5% methanol
is bad for your vehicle. Don’t use it.
It can corrode metal parts in your fuel
system and also damage plastic and
rubber parts. That damage wouldn’t
be covered under your warranty. And
even at
5% or less, there must be
“cosolvents” and corrosion prevent-
ers in this fuel to help avoid these
problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
additives will help prevent deposits from
forming in your engine and fuel system.
That helps keep your engine in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasalines are now blended with
oxygenates. General Motors recommend:
that you use gasolines with these blendin,
materials, such as MTBE and ethanol. BJ
doing
so, you can help clean the air,
especially
in those parts of the country
that have high carbon monoxide levels. n
addition, some gasoline suppliers are
low producing reformulated gasolines.
rhese gasolines are specially designed to
.educe vehicle emissions. General Motors
-ecommends that you use reformulated
;asoline. By doing
so, you can help clean
:he air, especially in those parts of the
:ountry that have high ozone levels.
You should ask your service station
3perators if their gasolines contain deposit
:ontrol additives and oxygenates, and
if
:hey have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
[f you plan on driving in another country
outside the
U.S. or Canada, unleaded fuel
may be hard to find. Do not use leaded
gasoline, If you use even one tankful,
your emission controls won’t work well
or at all. With continuous use, spark plugs
can get fouled, the exhaust system can
corrode, and your engine oil can
deteriorate quickly. Your vehicle’s oxygen
sensor will be damaged. All of that means
costly repairs that wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto
:lub, or contact a major oil company that
Joes business in the country where you’ll
,e driving.
You can also write us at the following
iddress for advice. Just tell
us where
you’re going and give your Vehicle
Identification Number (VIN).

Filling Your Tank
The cap is behind a hinged door on the
left side of your vehicle. To
take
off the cap, turn it slowly to the
left (counterclockwise).
Be careful not to spill gasoline. Clean
gasoline from painted surfaces as soon as
possible. See “Cleaning the Outside of
Your Pontiac” in
the Index.
When
you put the cap back on, turn it to
the right until you hear at least three
:licks.
NOTICE:
If you need a new cap, be sure to get
the right type. Your dealer can get
one
for you. If you get the wrong
type, it may not fit and your fuel tank
and emissions system might be dam-
aged.
