If your vehicle has the traction control
system, the
LOW TRACTION light will
come on when your anti-lock system is
adjusting brake pressure to help avoid a
braking skid. See Low Traction Light in
i
theIndex.
Traction Control System
(OPTION: 3800 V6 ENGINE)
Your vehicle may have a traction
control system that limits wheel spin.
This is especially useful in slippery road
conditions. The system operates only if
it senses that one or both
of the front
wheels are spinning or beginning to lose
traction.
When this happens, the system works
the front brakes and reduces engine
power (by shutting
off fuel injectors and
managing spark) to limit wheel spin. The
LOW TRACTION light
will come
on when your traction control system is
limiting wheel spin. See Low Traction
Light in the Index. You may feel the
system working, or you may notice
some noise, but this is normal.
If your vehicle is in cruise control when
the traction control system begins to
limit wheel spin, the cruise control will
automatically disengage. When road
conditions allow you to safely use it
again, you may re-engage the cruise
control. (See Cruise Control in the
Index
.)

your traction control system.
See Traction Control System Warning
Light in the Index. When this warning
light is on, the system will not limit
wheel spin. Adjust your driving
accordingly.

What should you do if this ever
happens? Ease up on the accelerator
pedal, steer the vehicle the way you
want it to go, and slow down.
Speed limit signs near curves warn that
you should adjust your speed. Of
course, the posted speeds are based on
good weather and road conditions.
Under less favorable conditions you’ll
want to go slower.
If you need to reduce your speed as you
approach a curve, do it before you enter
the curve, while your front wheels are
straight ahead.
Try to adjust your speed
so you can
“drive” through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until you are out of the curve,
and then accelerate gently into the
straightaway.
Steering in Emergencies
There are times when steering can be
more effective than braking. For
example, you come over a hill and find
a truck stopped in your lane, or a car
suddenly pulls out from nowhere, or a
child darts out from between parked
cars and stops
right in front of you. You
can avoid these problems by braking
-
if you can stop in time. But sometimes
you can’t; there isn’t room. That’s the
time for evasive action
- steering
around the problem,
Your Oldsmobile can perform very well
in emergencies like these. First apply
your brakes.
It is better to remove as
much speed
as you can from a possible
collision. Then steer around the problem,
to the left
or right depending
on the space available.
An emergency like this requires close
attention and a quick decision. If you
are holding the steering wheel at the
recommended
9 and 3 o’clock positions,
you can turn it a full
180 degrees very
quickly without removing either hand.
But you have to act fast, steer quickly,
and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations
are always possible is a good reason to
practice defensive driving at all times
and wear safety belts properly.

Loss of Control
Let’s review what driving experts say
about what happens when the three
control systems (brakes, steering and
acceleration) don’t have enough friction
where the tires meet the road to do
what the driver has asked.
In any emergency, don’t give up. Keep
trying to steer and constantly seek
an
escape route or area of less danger.
In a skid, a driver can lose control of
the vehicle. Defensive drivers avoid
most skids by taking reasonable care
suited to existing conditions, and by not
“overdriving” those conditions. But
skids are always possible.
The three types of skids correspond to
your Oldsmobile’s three control systems.
In the braking skid your
wheels aren’t rolling. In the steering or
cornering skid, too much speed or
steering in
a curve causes tires to slip
and lose cornering force. And in the
acceleration skid
too much throttle
causes the driving wheels to spin.
A cornering skid is best handled by
easing your foot
off the accelerator
pedal.
If you have the traction control
system, remember: It helps avoid only
the acceleration skid. If you do not have
traction control, or
if the system is off,
then an acceleration skid is also best
handled by easing your foot
off the
accelerator pedal.
If your vehicle starts to slide, ease your
foot off the accelerator pedal and
quicltly steer the way you want the
vehicle to go.
If you start steering
quickly enough, your vehicle may
straighten out. Always be ready for a
second skid
if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
you’ll want to slow down and adjust
your driving to these conditions. It is
important to slow down on slippery

Driving too fast through large water
puddles or even going through some car
washes can cause problems, too. The
water may affect your brakes. Try to
avoid puddles. But
if you can’t, try to
slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride on the water. This
can happen if the road is wet enough
and you’re going fast enough. When
your vehicle is hydroplaning, it has little
or no contact with the road.
Hydroplaning doesn’t happen often.
But it can if your tires haven’t much
tread or if the pressure in one or more is
low. It can happen
if a lot of water is
standing on the road. If you can see
reflections from trees, telephone poles,
or other vehicles, and raindrops
“dimple” the water’s surface, there
could be hydroplaning.
Hydroplaning usually happens at higher
speeds. There just isn’t a hard and fast
rule about hydroplaning. The best
advice is to slow down when it is
raining.
Some Other Rainy Weather Tips
Turn on your low-beam headlights -
not just your parking lights - to help
make you more visible to others.
Besides slowing down, allow some
extra following distance. And be
especially careful when you pass
another vehicle. Allow yourself more
clear room ahead, and be prepared to
have your view restricted by road
spray.
Have good tires with proper tread
depth. (See
Tires in the Index.)

Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain.
If you drive regularly in steep countly,
or if you’re planning to visit there, here
are some tips that can make your trips
safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most
important thing to know
is this: let
your engine do some
of the slowing
down. Shift to a lower gear when you
go down a steep
or long hill.

Whatever the condition - smooth ice,
packed, blowing or loose snow
- drive
with caution.
If you have the traction control system,
keep the system on. It will improve your
ability to accelerate when driving on a
slippery road. Even though your vehicle
has a traction control system, you’ll
want to slow down and adjust your
driving to the road conditions. See
Traction Control System in the Index.
If you don’t have the traction control
system, accelerate gently. Try not to
break the fragile traction. If you
accelerate too fast, the drive wheels will
spin and polish the surface under the
tires even more.
Your anti-lock brakes improve your
ability to make a hard stop
on a slippery
road. Even though you have an anti-
lock braking system, you’ll want to
begin stopping sooner than you would
on dry pavement. See
Anti-lock in the
Index.
Allow greater following distance on
any slippery road.
Watch for slippery spots. The road
might be fine until you hit a spot that’s
covered with ice.
On an
otherwise clear road, ice patches may
appear in shaded areas where the
sun
can’t reach: around clumps of trees,
behind buildings, or under bridges.
Sometimes the surface of a curve or
an overpass may remain icy when the
surrounding roads are clear. If you see
a patch of ice ahead of you, brake
before you are
on it. Try not to brake
while you’re actually on the ice, and
avoid sudden steering maneuvers.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation.
You
should probably stay with your vehicle
unless you know for sure that you are
near help and you can hike through the
snow. Here are some things to do to
summon help and keep yourself and
your passengers safe: Turn on your
hazard flashers. Tie a red cloth to your
vehicle
to alert police that you’ve been
stopped by the snow. Put on extra
clothing or wrap a blanket around you.

clothing, make body insulators from

hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
Safety Chains
You should always attach chains
between
your vehicle and your trailer.
Cross the safety chains under the
tongue of the trailer
so that the tongue
will not drop to the road if it becomes
separated from the hitch. Instructions
about safety chains may be provided by
the hitch manufacturer
or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave
just enough slack
so you can turn with
your rig. And, never allow safety chains
to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000
pounds (450 kg) loaded, then it needs
its own brakes
- and they must be
adequate. Be sure to read and follow
the instructions for the trailer brakes
so
you’ll be able to install, adjust and
maintain them properly. Because
you have anti-lock brakes, do
not try to tap into your vehicle‘s brake
system. If you do, both brake systems
won’t work well, or at all.
Driving with a Trailer
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
so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, 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.
ProCarManuals.com

During your trip, check occasionally to
be sure that the load is secure, and that
the lights 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.
Passing
You’ll need more passing distance up
ahead when you’re towing a trailer.
And, because you’re a good deal longer,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the
trailer to the left, just move that hand to
the left.
To move the trailer to the right,
move your hand to the right. Always back up
slowly and, if possible, have
someone guide you.
Making Turns
When you’re turning with a trailer,
make wider turns than normal. Do this
so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights 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 lwh) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer that weighs
more than
1,000 pounds (454 kg), and
you have an automatic transaxle with
Overdrive, you may prefer to drive in
D
instead of Overdrive (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. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place choclts under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
apply your parking brake, and then
shift to
P (Park).
4. Reapply the regular brakes. Then
5. Release the regular brakes.
When You Are Ready to Leave

2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
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 quicltly. 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.
