Driving with a Trailer
A -CAUTION:
I
If you have a rear-most window open and you
pull
a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.)
To
maximize your safety when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting
on your trip.
0 Keep the rear-most windows closed.
0 If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
RECIRC because it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.)
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight
of the
trailer. And always keep in mind that the vehicle you are
driving
is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection
at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without
a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.

Driving On Grades Parking on Hills
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 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), and you have an automatic transaxle
with AUTOMATIC OVERDRIVE
(@), you may prefer
to drive in THIRD (D) instead of AUTOMATIC
OVERDRIVE
(@) (or, as you need to, a lower gear).
This will minimize heat build-up and extend the life
of
your transaxle.
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. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK
(P).
5. 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;
0 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.

3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the 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!
I NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. 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.

5. Find the positive (+) and negative (-) terminals on
each battery.
Your Oldsmobile has
a remote positive (+)jump
starting terminal. The terminal is
in the red box
on the same side
of the engine compartment as
your battery. You should always use the remote
positive
(+) terminal instead of the positive (+)
terminal on your battery.
To open the remote positive
(+) terminal box, pull
the tab and open the cover.

&!, CAWTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded.
Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@ battery
(or batteries) installed in every new
GM vehicle.
But if
a battery has filler caps, be sure the right
amount of fluid is there.
If it is low, add water to
take care
of that first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
6. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before you connect the cables, here are some things
you should know. Positive
(+) will go to positive (+)
and negative (-) will go to negative (-) or a metal
engine part. Don’t connect positive
(+) to negative (-)
or you’ll get a short that would damage the battery
and maybe other
parts, too.
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.
7. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Use a
remote positive
(+) terminal if the vehicle has one.

8. Don’t let the other end
touch metal. Connect
it
to the positive (+)
terminal of the good
battery. Use
a remote
positive
(+) terminal if
the vehicle has one.
9. Now connect the black
negative
(-) cable to
the good battery’s
negative
(-) terminal.
Don’t let
the other end
touch anything
until the
next step. The other end
of the negative (-) cable
doem ’t go to the dead
battery. It goes to
a heavy
unpainted metal
part on
the engine
of the vehicle
with the dead battery.
10. Attach the cable at least
18 inches (45 cm) away
from the dead battery,
but not near engine
parts that move.
The electrical connection is just
as good there, but
the chance
of sparks getting back to the battery is
much less.
1 1. Now start the vehicle with the good battery and run
the engine for a while.
12. Try to start the vehicle with the dead battery. If it
won’t start after a few tries, it probably needs service.

13. Remove the cables in reverse order to prevent
electrical shorting. Take care that
they don’t touch
each other or any other metal.

Towing Your Vehicle
Try to have a GM retailer or a professional towing
service tow your Silhouette. They can provide the right
equipment and know how to tow your vehicle without
damage. See “Roadside Assistance”
in the Index.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on
the hazard
warning flashers.
When
you call, tell the towing service:
That your vehicle cannot be towed from the front
with sling-type equipment.
That your whicle has front-wheel drive.
0 The make, model, and year of your vehicle.
0 Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives,
let the tow operator
know that this manual contains detailed towing
instructions and illustrations.
The operator may want to
see them.

Attach a separate safety chain around the end of each
axle inboard
of the spring.
Engir Overheating
You will find a coolant temperature gage on your
Oldsmobile’s instrument panel. See “Engine Coolant
Temperature Gage”
in the Index. You also have a low
coolant level light on your instrument panel. See “Low
Coolant Light” in the Index.

/11 CA JTILV:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine
if you see or hear steam coming
from it. Just turn
it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids
in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
I NOTICE:
r
~ ~~
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty.
If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or THLRD (D).
ProCarManuals.com

If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back
on, you can
drive normally. When you
decide it’s safe to
lift the hood, here’s what
you‘ll see:
If the warning continues,
pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops.
But then, if you still have the
warning, turn 08 the engine and get everyone out of the
vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.
