Oil Level
Warning Light
Your vehicle may be equipped with an oil
level monitoring system. When the
ignition key is turned on, the light will
briefly flash. If the light stays on, stop the
vehicle on a level surface and turn the
engine off. Check the oil level using the
engine oil dipstick. (See the Index under
“Engine Oil.”) If the light does not flash,
have the low oil level sensor system
repaired
so it will be ready to warn you if
there’s a problem.
NOTE: The oil level monitoring system
only checks oil level during the brief
period between key on and and engine
crank.. It does not monitor engine ail 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.
Oiil Warning Light
If you have a problem with your oil, this
light may stay on after you start your
engine, or come 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 problem.
Have
it fixed right away.
The oil light could also come on in three
other situations:
0 When the ignition is on but the engine
is not running, the light will come on
as a test to show you it is working, but
the light will go out when you turn the
ignition to “Start”. If it doesn’t come

slightly warmer air is directed through th
heater ducts and defroster vents. At time:
this temperature difference may be more
apparent than others.

temperatures are mild, and little heating
or cooling
is needed. Air flow is through
the instrument panel outlets. Set the

Problems on the Road
1 Cooling System (CONK)
If the coolant inside the coolant surge
tank is boiling, don’t do anything else
until it cools down. The coolant level should be at or above
FULL COLD. If it isn’t, you may have a
leak in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system. ~~~
NOTICE:
Engine
damage from running your
engine without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see
if the electric engine fan is running. If the
engine is overheating, the fan should be
running. If it isn’t, your vehicle needs
service.

How to Add Coolant to the
Coolant Surge Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above
FULL
COLD,-add a 50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze
at the coolant surge tank, but be
sure the cooling system, including the
coolant surge tank pressure cap, is cool
before
you do it. (See “Engine Coolant”
in the Index for more information about
the proper coolant
mix.)
NOTICE:
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other
parts. So use
the recommended coolant.

4. With the coolant surge tank pressure
cap off, start the engine and let
it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine fan.
By this time, the coolant level inside
the coolant surge tank may be lower. If
the level is lower, add more
of the
proper
mix to the coolant surge tank
until the level reaches FULL COLD,
or just above the small cylinder at the
base
of the opening.

5. Then replace the pressure cap. Be sure
the pressure cap is tight.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while
you’re driving, especially
if you maintain
your tires properly. If air goes out
of a
tire, it’s much more likely to leak out
slowly. But if you should ever have a
“blowout,” here are
a few tips about what
to expect and what to do:
If a front tire fails, the flat tire will create
a drag that pulls the vehicle toward that
side. Take your foot off the accelerator
pedal and grip
the steering wheel firmly.
Steer to maintain lane position, then
gently brake to
a stop well out of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the
same correction you’d use in a skid. In
my rear blowout, remove your foot from
the accelerator pedal. Get the vehicle
under control by steering the way you
want the vehicle to go. It may be very
wmpy and noisy, but you can still steer.
Sently brake to a stop, well off the road if
Jossible.
[fa tire goes flat, the next section shows
low to use your jacking equipment to
:hange a
flat tire safely.

Service & Appearance Care
How to Check:
The proper fluid should be added if the
level is at or below the STEP mark on the
reservoir cap. See the instructions on the
reservoir cap.
Engine Coolant
The following explains your cooling
system and how to add coolant when
it is
low.
If you have a problem with engine
overheating, see “Engine Overheating”
in
the Index,
The proper coolant for your Pontiac will:
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
( 128 “C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to GM Specification 1825-M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else. NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your
warranty. Too much water
in the
mix can freeze and crack the engine,
radiator, heater core and other parts.

Adding Coolant
To Check Coolant:
When your engine is cold, the coolant
level should be at the
FULL COLD
mark, or a little higher.
To Add Coolant:
If you need more coolant, add the proper
mix at the surge tank, but only when the
engine
is cool.
