Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Oldsmobile retailer. The green 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 green 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
I NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before 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 kmk) to reduce the
possibility
of engine and transaxle overheating.
Pay attention to the engine coolant gage.
If the indicator
is in the red area,
turn off the air conditioning (if you
have
this option) to reduce engine load (see “Engine
Overheating” in the Index).

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 shift into 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, belt, 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.
2. 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.
You could be injured
if the vehicles roll. Set the
parking brake firmly on each vehicle. Put the
transaxle in
PARK (P).

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. Heater and radiator
hoses, and other engine
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.
I 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.

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 andor 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
("T);
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. 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.

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. 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
OF spill
things that will burn onto a hot engine.
The following sections tell you how to check fluids,
lubricants and important parts under the hood.
Hood Release
To open the hood, first pull
the hood release handle
inside the vehicle.

Engine Oil
CHECK
OIL
If the CHECK OIL
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 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
handle is yellow ,and
located on the front of
the engine.
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.
ProCarManuals.com

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 Oil
If the oil is at or below the ADD line, 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 upper
mark that shows the proper operating range,
your engine could be damaged.
