Anti-Lock Brake System Active Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the anti-lock brake system
active light will come
on.
Engine Coolant Temperature Light
HOT
This light tells you that
your engine coolant has
overheated or your radiator
cooling fan is not working.
Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active light also comes on
briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have
it fixed so it will be
there to
tell you when the system is active. If you
have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Thrn 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
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 krn/h) to reduce the
possibility
of engine and transaxle overheating. If you
have overdrive, you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (a)
(or, as you need to, a lower gear).
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. Apply your regular brakes, but don’t shift into
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. PARK
(P) yet.

Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel.
See
“Engine Coolant Temperature Gage” and “Engine
Coolant Temperature Warning Light” in the Index. You
also have a LOW COOLANT light on your instrument
panel.
See “Low Coolant Light” in the Index.
If Steam Is Coming From Your Engine
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:
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.
5-13

j If the coolant inside the coolant recovery tank is boiling,
don’t do anything
else until it cools down.
.. - ”r -+
Heater and radiator hoses, and otherengine
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 fiie,
and you could be burned.
Get any leak fixed before you drive the vehicle.
’
I NOTICE:
The coolant level should be at or above the COLD mark
on a cold engine. The coolant level should be at or
above the HOT mark on a hot engine. 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.
r
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 fan(s) are running. If the engine
is overheating, both fan@) should be running; If they
aren’t, your vehicle needs service.

How ,to Add Fluid Engine Coolant
I
Refer to the Maintenance Schedule to determine what
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
~ kind of transaxle fluid to use. See “Recommended ,
1. Pull out the dipstick.
.2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn’t take much fluid, generally less than a pint
(0.5 L). Don’t ove@ZZ. We recommend you use only
fluid labeled DEXRON@-111, ‘because fluid with that
label is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON-I11 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
0 When the correct fluid level is obtained, push the
dipstick back in all the way.
6-20
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating or if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
A
50/50 mixture of water and the proper.coolant for
your Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.

this it conies on, it
means you're low
on
engine coolant.
A4&g Coolant
- ..
Jfy& more coolant, add the proper mix at the. I
coolant recovery tank. I.
If the coolant recovery tank is. completely empty, add
,- ,coolant -to the radiator.. (See ,:'Engine Overheating" in-
the Index.) I'
A CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and' scalding liquids to blow out and burn you
badly. With the coolant recovery tank,-you
will
almost never have to add doolant at the radiator.
Never turn the radiatol' pressure cap
-- even a
little.-- when the engine and radiator
are. hot.
I Add coolant mix at the recovery tank, but be careful not
to
spill it.
I A CAUTION:
You can be burned if you,spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it
will burn if the engine parts are hot '
enough. Don't s,pill coolant on a hot engme.
