1993 BUICK RIVIERA wheel

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 and an acceleration skid are best
handled by easing your foot
off the accelerator pedal.
If your vehicle starts to slide (as when you turn a corner
on a wet, snow- or ice-covered road), ease your foot
off
the acceleratorpedal as soon as you feel the vehicle start
to slide. Quickly steer the way you want the vehicle to go. If you
start steering quickly enough, your vehicle
will straighten out.
As it does, straighten the front
wheels.
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 enoughewater, ice or packed snow on the road to make
a “mirrored surface” -- and slow down when you
have any doubt.
Remember: Any anti-lock braking system
(ABS) helps
avoid only the braking skid. Steer the way you want to
go.
Driving at Night
Night driving is more dangerous than day driving. One reason
is that some drivers are likely to be impaired --

Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
If you are moving from an outside to a center lane on a
freeway having more than two lanes, make sure another
vehicle isn’t about to move into the same spot. Look at
the vehicles two lanes over and watch for telltale signs:
turn signals flashing, an increase in speed,
or moving
toward the edge of the lane. Be prepared to delay your
move.
Once you are moving on the freeway, make certain you
allow a reasonable following. distance. Expect to move
slightly slower at night.
Leaving the Freeway
When you want to leave the freeway, move to the proper
lane well in advance. Dashing across lanes at the last
minute is dangerous.
If you miss your exit do not, under
any circumstances, stop and back up. Drive on to the
next exit.
At each exit point is a deceleration lane. Ideally it
should be long enough for you to enter it at freeway
speed (after signaling, of course) and then do your
braking before moving onto the exit ramp.
Unfortunately, not all deceleration lanes are long enough
-- some are too short for all the braking. Decide when to
start braking. If you must brake on the through lane, and
if there is traffic close behind you, you can allow a little \
extra time and flash your brake lights (in addition to
your turn signal) as extra warning that you are about to
slow down and exit.
The exit ramp can be curved, sometimes quite sharply.
The exit spwd 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. For example,
40 mph (65 h/h) might
seem like only
20 mph (30 km/h). Obviously, this. could
lead to serious trouble on a ramp designed for
20 mph
(30 km/h)!
Driving a Long Distance
Although most long trips today are made on freeways,
there are still many made
on regular highways.
Long-distance driving on freeways and regular
highways is the same in some ways. The
trip has to be
planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer
turns
behind the wheel. You’ll enjoy your trip more if you and
your vehicle are in good shape. Here are some tips for
a
successful long trip.

of the journey. Wear comfortable clothing and shoes you
can easily drive in. On the Road
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
Buick 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:
0 Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape!
0 Fuel, Engine Oil, Other Fluids: Have you checked all
levels?
0 Lights: Are they all working? Are the lenses clean?
0 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? Unless you
are the only driver, it is good to share
the
driving task with others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours at a sitting.
Then, either change drivers or stop for some refreshment
like coffee, tea or soft drinks and some limbering up. But do stop and move around. Eat lightly along the way.
Heavier meals tend to make some people sleepy.
On two-lane highways or undivided multilane highways
that do not have controlled access, you’ll want to watch for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers with direct access to the highway, no passing zones and school zones, vehicles turning left and right off the road,
pedestrians, cyclists, parked vehicles. td even animals.
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.

As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident. Parking on Hills
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones,
a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.
Winter driving can present special problems. See ,
“Winter Driving” in the Index.
Hills and mountains mean spectacular scenery. But
please be careful where you stop if you decide to look at
the view or take pictures. Look for pull-offs or parking
areas provided for scenic viewing.
Another part of this manual tells how to use your
parking brake (see “Parking Brake” in the Index). But
on a mountain or steep hill, you can do one more thing.
You can turn your front wheels to keep your vehicle
from rolling downhill or out into traffic.

Turn your wheels to the right.
You don't have to

there is
a curb. A gentle contact is all you need.
If there is a curb, turn your wheels to the left if the curb
is at the right side of your vehicle.

If you're going uphill on a one-way street and you're
parking on the left side, your wheels should point to the
right. If there is no curb when you're parking uphill, turn the
wheels to the right.

. . ._ . . .
Whatever the condition -- smooth ice, packed, blowing or
loose snow
-- drive with caution. 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 the
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.
