Brake Aflustment
Every time you make a moderate reverse
brake stop, your brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not
adjust correctly. If you drive
in that way,
then-very carefully-make a few
moderate brake stops about every
1,OOO
miles (1 600 km), so your brakes will
adjust properly.
If your brake pedal goes down farther
than
normal, your rear drum brakes may
need adjustment. Adjust them by
backing up and
firmly applying the
brakes a few times.
Braking In Emergencies
Use your anti-lock braking system when
you need to. With anti-lock, you can
steer and brake at the same time. In
many emergencies, steering can help
you more than even the very best
braking.
Power Steering -
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will
take
much more effort.

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 Pontiac’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 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 accelerator
pedal 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 change 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 braking
system
(ABS) helps avoid only the
braking skid.

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, 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 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:
Make sure your vehicle is well
ventilated, with a comfortably cool
interior.

Highway Hypnosis (CONI)
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.

d
Hill and Mountain Roads
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 enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transaxle. 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.
A
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.
ProCarManuals.com

CAUTION
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 your engine running and your
vehicle in gear when you go
downhill.
Know how to go uphill. Drive in the
highest gear possible.
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 falling
rocks area, or winding roads.

to these and take appropriate action.

Your Driving and the Road
Winter Driving
Here are some tips for winter driving:
Have your Pontiac in good shape for
winter. Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow, but
they may give you less traction on ice
than regular tires. If you do not expect
to be driving in deep snow, but may
have to travel over ice, you may not
want to switch to snow tires at all.
.a. 156
You may want to put winter
emergency supplies in your trunk.
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°F; OOC)
and freezing rain begins to fall. Try to
avoid driving on wet ice until salt and
sand crews can get there.

Put on extra clothing or wrap a
blanket around you.
If you have no
blankets or extra clothing, make body
insulators from newspapers, burlap
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.

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 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 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 a while.
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.

trailering capacity is for your vehicle,
you should read the information
in
Weight of the Trailer that appears later in
this section. But trailering is different
than just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful, safe trailering
takes correct equipment,
and it has to be used properly. That’s the reason for this section.
In it
are many time-tested, important
trailering tips and safety rules. Many
of
these are important for your safety and
that of your passengers.
So please read
this section carefully before you pull a
trailer.
Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tires are forced to work harder against
the drag
of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads, generating
extra heat. What’s more, the trailer adds
considerably to wind resistance,
increasing the pulling requirements.

If Bu Do Decide to Pull a Trailer
If you do, here are some important
points.
There are many different laws having
to do with trailering. Make sure your rig will be legal, not only where you
live but
also where you’ll be driving.
A good source for this information can
be state or provincial police.
Consider using a sway control. You
can ask a hitch dealer about sway
controls.
a Don’t tow a trailer at all during the
first
500 miles (804 km) your new
vehicle is driven. Your engine, axle or
other parts could
be damaged.
Then, during the first 500 miles
(804
km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and
don’t make
starts at full throttle. This
helps your engine and other parts of
your vehicle wear in at the heavier
loads.
Three important considerations have
to do with weight:
161
I. Weight of the Trailer
How heavy can a trailer safely be? It
should never weigh more than
1,OOO
pounds (450 kg).
But even that can be too heavy. It
depends on how you plan to use your
rig. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a
trailer are
all important. And, it can
also depend on any special equipment
that you have
on your vehicle.

Turn Signals When Towing a ’Railer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a
turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other drivers you’re about to turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signal when
they are not. It’s important to check occasionally to be sure the trailer bulbs
are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer work well.
On a long uphill grade, use the highest
gear possible. If you cannot maintain
posted speeds, driving at a lower speed
may help avoid overheating your engine
and transaxle.
If you have a manual transaxle with
fifth
gear, it’s better not to use fifth gear. Just
drive in fourth gear (or, as you need to,
a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached,
on a hill. If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer can
be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet, or into gear
for a manual transaxle.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the chocks absorb the load.
