I A CAUTION:
I
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.
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 headlamps. 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.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a different turn signal flasher.
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if
the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when
they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear befure you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000 lbs.
(454 kg), you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (D)
(or, as
you need to, a lower gear). This will minimize
heat build-up and extend the life of your transaxle.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a
hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK
(P) yet.
Have someone place chocks under
the trailer wheels.
When
the wheel chocks are in place, release the
regular brakes
until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift
to PARK (P).
Release the regular brakes.

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
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, belts, 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.

1. Check the other vehicle. It must have a 12-volt
battery with
a negative ground system.
NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
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 Oldsmobile, and the bad grounding could
damage the electrical systems.
NOTICE:
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).
2. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlet. 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!
NOTICE:
~~ -
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Open the hoods and locate the batteries.
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.

parts, can be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with
the engine on, check to
see if the electric engine fans are running.
If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
--overy Tank
lr you haven’t found a problem yet, but the coolant
level isn’t at or above the
FULL HOT mark, add a
50/50 mixture of clean water (preferably distilled) and
DEX-COOL TM (silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more information.)
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 mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, 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 mix of clean
water and
DEX-COOL TM antifreeze.

Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Oldsmobile retailer before adding equipment to the
outside
of your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At
a minimum, it should meet specifications
ASTM D4814
in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane is at least 87. 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 87 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.
If your vehicle is certified to meet California Emission
Standards (indicated on
the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail
a smog-check test. If this occurs, return to
your authorized Oldsmobile retailer for diagnosis
to determine
the cause of failure. In the event it is
determined that
the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for
low
emissions contain an octane-enhancing additive called
methylcyclopentadlenyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains
MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Oldsmobile retailer for service.

ProCarManuals.com

To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. 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.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell
us where you’re going and give your
Vehicle Identification Number
(VIN).

When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left
off or improperly
installed. Ths would allow
fuel to evaporate into the
atmosphere. See “Malfunction Indicator Lamp” in
the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you.
If you get
the wrong type,
it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
Checking Things Under 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.
1
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.

Pull forward on the hood prop to release it from its
storage clip. Then put the end of
the hood prop into the
slot in the underside of the hood.
Before closing the hood, be sure all the filler caps are on
properly.
Then lift the hood to relieve pressure on the
hood prop. Remove the hood prop from the slot
in the
hood and return the prop to its retainer. Then just let
the
hood down and close it firmly.
Underhood Lamp
Your underhood lamp will go on when you open the hood.
Engine Oil
LWEL
If the Low 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 “Low 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.
The engine oil dipstick
is located at the front of the engine
compartment, near the center. The dipstick handle has
a
bright, yellow loop design for easy identification.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
