pass while you’re awaiting an opportunity. For one
thing, following too closely reduces your area
of
vision, especially if you’re following a larger
vehicle. Also,
you won’t have adequate space if the
vehicle ahead suddenly slows or stops. Keep back
a
reasonable distance.
When it looks like a chance to pass is coming up,
start to accelerate but stay
in the right lane and don’t
get too close. Time your move
so you will be
increasing speed as the time comes
to move into the
other lane.
If the way is clear to pass, you will have a
“running start” that more than makes up for
the
distance you would lose by dropping back. And if
something happens
to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
0 If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull
out to pass the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.

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.

headlamps.
It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
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 E 1 Wet Roads

Downloaded from www.Manualslib.com manuals search engine Citv 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.
Here are ways to increase your safety in city driving:
0 Know the best way to get to where you are going. Get
a city map and plan your
trip into an unknown part of
the city just as you would for a cross-country hip.
0 Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)
0 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.

Mile for mile, freeways (also called thruways, parkways,
expressways, 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. At
the entrance, there is usually a ramp that leads to the
freeway. 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. Try to merge into the gap at close to
the prevailing speed. Switch on your turn signal, check
your mirrors and glance over your shoulder
as often as
necessary. Try to blend smoothly with the traffic flow.
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.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving
on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want
to leave the freeway, move to the proper
lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can
be curved, sometimes quite sharply.
4-19

Downloaded from www.Manualslib.com manuals search engine 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
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 inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
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?

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.
What can you do about highway hypnosis? First, be
aware that it can happen.

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.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
4-21

Downloaded from www.Manualslib.com manuals search engine 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 enjoyable.
1 .) 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.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they 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. Coasting downhill
in NEUTRAL (N) 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 would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
1 and your vehicle in gear when you go downhill.
0
0
0
0
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.
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 falling rocks area or
winding
roads. Be alert to these and take appropriate action.

Downloaded from www.Manualslib.com manuals search engine ’ A CAUTION:
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 is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
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 (or batteries) charged. You will need a
well-charged battery (or batteries)
to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for a while.
If you have a diesel engine,
you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this only
when
you feel really uncomfortable from the cold. But
do it as little
as possible. Preserve the fuel as long as you
can. To help keep warm, you can get out of the vehicle
and
do some fairly vigorous exercises every half hour or
so until help comes.
