After repositioning the crossrails, be sure to tighten the
release knobs by turning them clockwise, locking the
crossrails in place.

Use the adjustable tiedown loops in the side rails to help
secure large loads. Reposition the tiedowns by turning
them counterclockwise, then slide them along the side
rail. Turn the tiedowns clockwise
to tighten them in
place.
Tiedowns may be removed and used in the adjustable
tapped plates
in the crossrails. You may also use these
tapped plates
to secure bicycle or ski racks.
Air Inflator System (Option)
Your vehicle may be equipped with an air inflator. It will
be located in
the rear compartment on the driver's side
along with the accessory power outlet. With
it, you can
inflate things like air mattresses and basketballs, and
you can also use it to bring your tires up to the proper
pressure.
To open, slide the latch down and remove the cover.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes,
as when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and reaction
time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do
it. That’s reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and
as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight
all play a part. So do alcohol, drugs and
frustration.
But even in 3/4 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be
a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface
of the road (whether it’s pavement or
gravel); the condition
of the road (wet, dry, icy); tire
tread; and the condition
of your brakes.

Steering
Power Steering
If you lose power steering assist because the engine
stops or the system
is not functioning, you can steer but
it will take much more effort.
Steering Tips
Drividg tML Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws
of physics when driving on curves. The
traction of the tires against the road surface makes
it
possible for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this. Suppose you’re
steering through a sharp curve. Then
you suddenly accelerate. Both control systems
--
steering and acceleration -- have to do their work where
the tires meet the road. Unless you have traction control
and the system
is on, adding the sudden acceleration can
demand too much of those places. You can lose control.
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.
The traction you can get in a curve depends on
the
condition of your tires and the road surface, the angle
at which the curve
is banked, and your speed. While
you’re in a curve, speed is the one factor you can
control.

Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem to be farther away from you
than it really
is.)
Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver
to get ahead of you. Perhaps you
can ease a little to the right.
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.
Skidding
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
A 1A
ProCarManuals.com

is off, then an acceleration skid is also best handled by
easing your foot
off the accelerator pedal.
Driving at Night
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly 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
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.
Remember: Any anti-lock brake system
(ABS) helps
avoid
only the braking skid. Night
driving
is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.

Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up
a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less
of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren’t even aware of it.
Driving in the Rain
I
Rain and wet roads can mean driving trouble. On a wet
road
you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t
as good as on dry roads.
And, if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to
go slower and be
cautious if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.

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 headlamps -- not just your
parking lamps
-- 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.)
City Driving
One of the biggest problems with city streets is the
amount of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention
to
traffic signals.

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

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 u second, and you could crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:

0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to
the sides. Check your mirrors and your instruments
frequently.
If you get sleepy, pull
off the road into a rest, service,
or parking area and take
a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel,
a flashlight, a red cloth, and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece
of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However,
if there is snow or ice between your tires and
the road, you can have
a very slippery situation. You’ll
have a lot less traction or “grip” and will need to be very
careful.
What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get “wet ice” when it’s
about freezing
(32 OF; 0” C) and freezing rain begins to
fall. Try
to avoid driving on wet ice until salt and sand
crews can get there.
