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, and be
.
careful.

Turn on your headlights -- not just your parking
lights
-- to help make you more visible to others.
Look for hard-to-see vehicles corning from behind.
You may want to use your headlights even in
daytime if it’s raining hard.
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. If the road spray is
so heavy you are
actually blinded, drop back. Don’t pass until conditions improve. Going more slowly
is better
than having an accident.
Use your defogger
if it helps.
Have good tires with proper tread depth. (See
“Tires” in the Index.)
Driving in Fog, Mist and Haze
IIII
Fog can occur with high humidity or heavy frost. It can,
be
so mild that you can see through it for several
hundred feet (meters).
Or it might be so thick that you
can see only a few feet (meters) ahead. It may come
suddenly to an otherwise clear road. And it can be a
major hazard.
When you drive into a fog patch, your visibility will be
reduced quickly. The biggest dangers are striking the
vehicle ahead
or being struck by the one behind. Try to
167

Don’t use your high beams. The light will bounce off
the water droplets that make up fog and reflect back at
you.
Use your defogger.
In high humidity, even a light
buildup of moisture on the inside of the glass will cut
down on your already limited visibility.
Run your
windshield wipers and washer ‘occasionally. Moisture
can build up on the outside glass, and what seems to be
fog may actually be moisture on the outside of your
windshield.
Treat dense fog as an emergency.
Try to find a place to
pull off the road. Of course you want to respect
another’s property, but you might need to put something
between you and moving vehicles
-- space, trees,
telephone poles, a private driveway, anything ,that
removes you from other traffic.
If visibility is near zero and you
must stop but are
unsure whether you are away from the road, tu_m your
lights on, start your hazard warning flasher, and sound your horn at intervals or when you hear approaching
traffic.
Pass other vehicles in fog only if you can see far enough
ahead to pass safely. Even then, be prepared to delay
your pass if you suspect the fog is worse up ahead.
If
other vehicles try to pass you, make it easy for them.

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.
172

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.
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.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors frequently
and your instruments from time to time. This can
help you avoid a fixed stare.'
Wear good sunglasses in bright light. Glare can
cause drowsiness. But don't wear sunglasses at
night. They will drastically reduce your overall vision at the very time you need all the seeing power
you have.
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.
As in any driving situation, keep pace with traffic and
allow adequate following distances.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
I
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.
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.
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
179

bags, rags, floor mats -- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can’t see
it or
smell it,
so you might not know it was in your
vehicle. Clear away snow from around the ba
!
of your vehicle, especially any that is blocking
your exhaust pipe- And check ar
from time to time to be sure snow
collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This
will heir
keep CO out.
I CAUTION: (Continued)
Run your engine only
as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That is, push the accelerator slightly.
This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.

Hazard Warning Flashers
c
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front and
rear turn signal lights will flash on and
off.

I
Press the button in to make your front and rear turn
signal lights flash on and
off.
Your hazard warning flashers work no matter what
position your key is in, and even
if the key isn't in.
To turn off the flashers, pull out on the collar. When the
hazard warning flashers are on, your
turn signals won't
work.
Other Warning Devices
If you carry reflective triangles, you can set one up at
the side
of the road about 300 feet (100 m) behind your
vehicle.

3. Turn off the ignition on both vehicles. Turn off all
lights that aren’t needed, and radios. This
will avoid
sparks and help save both batteries. And it could
save your radio!
4. Open the hoods and locate the batteries.

An electric fan can start up even when the
engine is not running and can injure you. Keep
hands; clothing and tools away from any
underhood electric fan.
