oil level PONTIAC BONNEVILLE 1998 Owners Manual

Oil Pressure Gage
The oil pressure gage
shows the engine oil
pressure in psi (pounds
per square inch) when the
engine
is running. Canadian
vehicles indicate pressure
in kPa (kiloPascals).
Oil pressure may
vary with engine speed, outside
temperature and oil viscosity, but readings above the red
warning zone indicate the normal operating
range.
A reading in the red zone may be caused by a
dangerously low oil level or other problem causing
low oil pressure. On vehicles with the optional
DIC,
the CHECK GAGES light will go on and a warning
chime will sound, if you have this option. Driving
your vehicle with low oil pressure can cause extensive
engine damage.
I A CAUTION:
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: I
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

If the engine oil is more than one quart (0.95 L) low and
the engine has been shut off for at least eight minutes,
the CHECK OIL LEVEL light will turn on for about
one minute and will then remain off until the next time
you start the vehicle.
If the CHECK OIL LEVEL light turns on, the engine oil
level should be checked at the dipstick then brought up
to the proper level, if necessary. See “Engine Oil” in
the Index.

Boost Gage (Option) Head-Up Display (Option)
fXjST
Vehicles equipped with the supercharged engine have
this boost gage that indicates vacuum during light
to
moderate throttle and boost under heavier throttle. The
gage displays the air pressure level in psi going into the
engine’s combustion chamber.
The gage is automatically centered at zero psi every
time the engine is started. Actual vacuum or boost
is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains
and changing
weather, will slightly change the zero reading.
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it’s dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some
of the driver information also available on
your instrument panel cluster. The information
may be
displayed in English or metric units and appears as a
reflection on the windshield. The
HUD shows:
0 Speedometer reading
0 Turn signal indicators
0 High-beam indicator symbol
CHECK GAGES message (for low oil pressure, high
coolant temperature, low oil level and low fuel)
Low fuel warning symbol
2-74

If you can’t see the HUD image when the ignition is on,
check to see if:
0 The headlamps are on.
0 The HUD unit is covered.
0 The HUD dimmer control is adjusted correctly.
0 The HUD image is adjusted to the proper height.
A fuse in the fuse panel may be blown. See “Fuses
and Circuit Breakers” in the Index.
If the HUD image is not clear, it could be too bright.
Move the HUD dimmer control further downward. You
may need to clean the windshield and
HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new
windshield, be sure to get one
designed for HUD. If you don’t, the HUD image may
look blurred
and out of focus.

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 fiid 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:

Lumps: Are they all working? Are the lenses clean?
Zlres: 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?

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a
50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
engine coolant at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
I A CAUTION:
~
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water
or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned. Use
a
50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

Supercharged Engine (If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device designed to pump more air
into the engine than it would normally use.
This air,
mixed with fuel, creates increased engine power. Since
the supercharger is a pump and is driven from an engine
accessory drive belt, increased pressure is available at
all driving conditions.
The Powertrain Control Module (PCM), works with a vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such
as during
idling and light throttle cruising, the excess
air that the
supercharger is pumping is routed through
a bypass.
All of these controls, working together, provide high
performance character and fuel efficiency in the
3800 V6 Supercharged engine.
Engine Oil
CHECK OIL
LEVEL
If the CHECK OIL LEVEL
light on the instrument panel
comes
on, it means you need
to check your engine oil level
right away.
For more
information,
see “Check Oil
Level Light” in the Index. You
should check your engine oil level regularly;
this is
an added reminder.
It’s
a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstic\
k
might not show
the actual level.
6-13

Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the
tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the ADD mark, then you’ll need
to add at least one quart
of oil. But you must use the
right kind.
This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched
area that shows the proper
operating
range, your engine could be damaged.
The engine oil fill cap is behind the engine oil dipstick
and engine fans.
Be sure to fill it enough to put the level somewhere in
the proper operating range.
Push the dipstick all the
way back
in when you’re through.
