When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test
is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal. Let’s say the road
is wet and you’re driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here’s what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.

Of course, traction is reduced when water, snow, ice, Driving at Night
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
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration
or braking (including engine braking by shifting to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues
- such as enough water, ice or packed snow
on the road to make a “mirrored surface”
- and slow
down when you have any doubt.
If you have the anti-lock braking system, remember: It
helps avoid only the braking skid.
If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the

brakes to get the wheels rolling again. This restores
steering control. Push the brake pedal down steadily Night driving is more dangerous than day driving.

Hydroplaning doesn’t happen often. But it can if your Driving Through Flowing Water
tires do not have 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.
Driving Through Deep Standing Water
Notice: If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that
is
slightly lower than the underbody of your vehicle. If
you can’t avoid deep puddles or standing water,
drive through them very slowly. Fla
ng or rushi - ater creates strong
forces. If you try to drive through flowing
water, as you might at a low water crossing,
your vehicle can be carried away.
As little as
six inches
of flowing water can carry away a
smaller vehicle. If this happens, you and other
vehicle occupants could drown. Don’t ignore
police warning signs, and otherwise be
very cautious about trying to drive through
flowing water.
Some Other Rainy Weather Tips
e 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
on page 5-53.

The exit ramp can be curved, sometimes quite sharply.
The exit speed
is usually posted. Reduce your speed
according
to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend
to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip?
If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll be
ready and willing
to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short time
to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Don’t
let it happen to you!
If it does, your vehicle can leave
the road in
less than a second, and you could crash and
be injured.
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

label found on the rear edge of the driver’s door tells
you the proper size, speed rating and recommended
inflation pressures for the tires on your vehicle. It also
gives you important information about the number
of people that can be in your vehicle and the total weight
that you can carry. This weight is called the Vehicle

The other label is the Certification label, found on
the rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the Gross

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer.
If you ever have questions
about your tire warranty and where to obtain service,
see your Oldsmobile Warranty booklet for details.
r--
Poorly maintained and improperly used tires
are dangerous.
0 Overloading your tires can cause
overheating as a result of
too much
friction. You could have an air-out and a
serious accident. See “Loading Your
Vehicle” in the Index.
CAUTION: (Continued)
4 inflated tires pose -..? same c ~ lger

I could cause serious injury. Check all tires
frequently to maintain the recommended
~ pressure. Tire pressure should be checked
when your tires are cold.
~ Overinflated tires are more likely to be
cut, punctured or broken by a sudden
~ impact - such as when you hit a pothole.
Keep tires at the recommended pressure.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the rear
edge of the driver’s door, shows the correct inflation
pressures for your tires when they’re cold. “Cold’’ means
your vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Notice: Don’t let anyone tell you that underinflation
or overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can get
the following:
Too much flexing
Too much heat
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire.
It should be at
60 psi
(420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards
5-54

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page
5-56 and Wheel Replacement
on page
5-59 for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Part A: Scheduled
Maintenance Services,” in Section 6, for scheduled
rotation intervals. Don’t include the
compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the Tire-Loading
Information label.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and
Specifications on page
5-86.
Rust or dirt on a wheel, or or parts to
which
it is fastened, can make wheel nuts
become loose after a time. The wheel could
come
off and cause an accident. When you
change a wheel, remove any rust
or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do
this; but be sure to use a

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly.
It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should
stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made
to perform well at speeds up to 65 mph
(1 05 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size
tire repaired or replaced where you want. Of course, it’s
best to replace your spare with a full-size tire as
soon as you can. Your spare will
last longer and be in
good shape in case you need it again.
Nofice: When the compact spare is installed, don’t
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught
on the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare tire
and its wheel together.
Notice: Tire chains won’t fit your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
