6. Then fill the coolant recovery tank to
the COLD mark. 7. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap
off.
8. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fans.
9. By this time, the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper mix through the filler neck
until the level reaches the base of the
filler neck.

Ifa 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 trafEic 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 any 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 bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the
next section
shows how to use your jacking
equipment to change a flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level
place. Turn on
your hazard warning flashers.
1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Turn off the engine.
To be even more certain the vehicle won't move, you can put chocks at the
front and rear of the tire farthest away
from the one being changed. That would
! the tire on the other side of the vehicle. at the omosite end.
c& ..:
The following steps will tell you how to
use the jack and change a tire.
The equipment you'll need is
in the
trunk.
1. Pull the carpeting from the Boor of
the trunk.
2. Turn the center retainer bolt on the
compact spare tire housing
countercloclwise to remove it, then
lift
the^ tire cover.

CAUTION I
A
If you let your tires spin at
high speed, they can explode
and you or others could be injured.
And, the transaxle or other parts of
the vehicle can overheat. That
could cause an engine compartment
fire or other damage. When you’re
stuck, spin the wheels as little as
possible. Don’t spin the wheels
above
35 mph (56 lun/h) as shown
on the speedometer.
Rocking Your Vehicle to Get it Out:
First, turn your steering wheel left and
right. That will clez the area around
your front wheels. Then shift back and
forth between
R (Reverse) and a
forward gear, spinning the wheels as
little as possible. Release the accelerator
pedal while you shift, and press lightly
on the accelerator pedal when the
transaxle
is in gear. If that doesn’t get
you
out after a few tries, you may need
to be towed out. If you do need to be
towed out, see the
Index under Towing
Your Oldsmobile.

If it’s bad enough, it can damage your
engine.
If you’re using fuel rated at 87 octane or
higher and you still hear heavy
laoclcing, 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.
Fuel Capacity:
16.5 U.S. Gallons (62 L). Use unleaded
fuel only.
What about gasoline with blending
materials that contain oxygen, such
as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl
ether.’’ Fuel that is no more than
15%
MTBE 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.

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits
from forming in your engine and fuel
system. That helps Beep 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 gasolines are now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines with these blending materials,
such as MTBE and ethanol. By doing
so, you can help clean the air, especially
in those parts of the country that have
high carbon monoxide levels. In
addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed
to reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline. By doing
so, you
can help clean the air, especially in
those parts of the country that have
high ozone levels.
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and
if they
have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
If 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.

Then go to the front of the vehicle and
release the secondary hood release.
Lift the hood. An electric fan
under the
hood can start up and injure
you even when the engine is not
running. Keep hands, clothing and
tools away from any underhood
electric fan.

Things that burn can get on

oil, coolant, brake fluid,
