Driving too fast through large water puddles or even going thr\
ough 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.
Wet brakes can cause accidents. They won’t work well in a quick
stop and may cause pulling
to one side. You could lose control of
the vehicle.
After driving through a large puddle of water or a car wash, apply
your brake pedal lightly until your brakes work normally.

Hydropraning
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.
You might not be aware of hydroplaning. You could drive along for some time
without realizing your tires aren’t in constant contact with the road. You could
find out the hard way: when you have
to slow, turn, move out to pass-or if
you get hit by a gust of wind. You could suddenly find yourself out of control.
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 s\
urface, 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.
Some Other Rainy Weather Tips
Turn on your headlights-not just your parking lights-to help ma\
ke you more visible
to others.
Look for hard-to-see vehicles coming 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 be\
tter 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
I ~
AN459007
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
4-28

Downloaded from www.Manualslib.com manuals search engine 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 ieduced quickly. The
biggest dangers are striking the vehicle ahead
or being struck by the one
behind. Try
to “read” the fog density down the road. If the vehicle ahead
starts
to become less clear or, at night, if the taillights are harder to see, the
fog is probably thickening. Slow down to give traffic behind y\
ou a chance
to
slow down. Everybody then has a better chance to avoid hitting the vehicle
ahead.
A patch of dense fog may extend only for a few feet (meters) or for miles
(kilometers); you can’t really tell while you’re in
it. You can only treat the
situation with extreme care.
One common fog condition-sometimes called mist
or ground fog-can
happen in weather that seems perfect, especially at night
or in the early
morning in valley and low, marshy areas. You can be suddenly enveloped in
thick, wet haze that may even coat your windshield. You can often spot these
fog patches
or mist layers with your headlights. But sometimes they can be
waiting for you as you come over a hill
or dip into a shallow valley. Start
your windshield wipers and washer,
to help clear accumulated road dirt. Slow
down carefully.
Tips on Driving in Fog
If you get caught in fog, turn your headlights on low beam, even\
in daytime.
You’ll see-and be seen-better. Use your fog lights
if your vehicle has them.
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. Ru\
n your
windshield wipers and washer occasionally. Moisture can build up\
on the outside glass, and what seems to be fog may actually be moist\
ure 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 traffi\
c.
If visibility is near zero and you must stop but are unsure whether you are
away from the road, turn your lights on, start your hazard warning flashers,
and sound your horn at intervals
or when you hear approaching traffic.
4-29

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
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.
City Driving
AM460005
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.
Here are ways to increase your safety in city driving:
e
e
e
e
Know the best way to get to where you are going. Try not to drive
around trying to pick out a familiar street or landmark. Get \
a city map
and plan your trip into an unknown part of the city just as you would for
a cross-county trip.
Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy. (See the next section, “Freeway Drivi\
ng.”)
Treat a green light as a warning signal.
A traffic light is there because
the corner is busy enough to need
it. When a light turns green, and just
before you start to move, check both ways for vehicles that have not
cleared the intersection or may be running the red light.
Obey all posted speed limits. But remember that they are for ideal road,
weather and visibility conditions. You may need to drive below the
posted limit in bad weather
or when visibility is especially poor.
Pull to the right (with care) and stop clear of intersections when y\
ou see
or hear emergency vehicles.

I
P
AN461001
Mile for mile, freeways (also called thruways, parkways, expres\
sways,
turnpikes, or superhighways) are the safest of all roads. But they have their
own special rules.
The most important advice on freeway driving is: Keep up with \
traffic and
keep
to the right. Drive at the same speed most of the other drivers \
are
driving. Too-fast or too-slow driving breaks a smooth traffic
flow. Treat the left
lane on a freeway as a passing lane.
Entering the Freeway
At the entrance there is usually a ramp that leads to the freewa\
y. If you have
a clear view of the freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine where you expect to blend
with the flow.
If traffic is light, you may have no problem. But if it is heavy,
find a gap as you move along the entering lane and time your\
approach. Try
to merge into the gap at close to the prevailing speed. Switc\
h on your turn
signal, check your rearview mirrors as you move along, and gla\
nce over your
shoulder as often as necessary.
Try to blend smoothly with the traffic flow.

Driving on the Freeway
Once you are on the freeway, adjust your speed to the posted \
limit or to the
prevailing rate
if it’s slower. Stay in the right lane unless you want to pass. If
you are on a two-lane freeway, treat the right lane as the s\
low lane and the
left lane as the passing lane.
If you are on a three-lane freeway, treat the right lane as the \
slower-speed
through lane, the middle lane as the higher-speed through lane,\
and the left lane as the passing lane.
Before changing lanes, check your rearview mirrors. Then use yo\
ur turn
signal. Just before you leave the lane, glance quickly over yo\
ur 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 yo\
ur
braking before moving onto the exit ramp. Unfortunately, not al\
l 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\
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. For example,\

40 mph (65 km/h) might seem like only 20 mph (30 kmk). Obviously, this
could lead to serious trouble on
a ramp designed for 20 mph (30 kmlh)!

Downloaded from www.Manualslib.com manuals search engine Driving On a Long nip
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.
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
GM 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 reservoir full? Are all windows clean
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: 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?
Should you delay your trip a short time to avoid a major storm system?
inside and outside?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
On the Road
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 refres\
hment
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.
4-33

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
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 cen\
ters with
direct access to the highway, no passing zones and school zones, vehicles
turning left and right
off the road, pedestrians, cyclists, parked vehicles, and
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.
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 le\
t 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:
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 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 adequat\
e
following distances.

AM470001
Driving on steep hills or mountains is different from driving in flat or rolling
terrain.
If you drive regularly in steep country, or if you're planning to visit
there, here are some tips that can make your trips safer and more enjoyab\
le.
Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. 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. Don't make your brakes
do it all. Shift
to a lower gear when you go down a steep or long hill.
That way, you will
slow down without excessive use of your brakes.
* If you don't shift down, your brakes could get so hot that they
L b wouldn't work well. You would then have poor braking or even none
going down a hill. You could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.

I
CAUTION 1
A
Coasting downhill in N (Neutral) or with the ignition off is dangerous.
Your brakes
will have to do all the work of slowing down. They could
get
so hot that they wouldn’t work well. You could crash. Always
have vour ignition on and vour vehicle in aear when you go downhill.
--
Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you can
climb the hill better.
Stay in your own lane when driving on two-lane roads in hills or
mountains. Don’t swing wide or cut across the center of the\
road. Drive
at speeds that let you stay in your own lane. That way, you won’t be
surprised by a vehicle coming toward you in the same lane.
It takes longer to pass another vehicle when you’re going uphill. You’ll
want to leave extra room to pass.
If a vehicle is passing you and
doesn’t have enough room, slow down to make it easier for the other
vehicle to get by.
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.
You may see highway signs on mountains that warn
of special problems.
Examples are long grades, passing or no-passing zones, a fallin\
g rocks
area, or winding roads. Be alert
to these and take appropriate action.
Winter driving can present special problems. See “Winter Driv\
ing” ,,in the
Index.
