Your Driving and the Road
There’s something else about drinking
and driving that many people don’t know.
Medical research shows that alcohol
in a
person’s system can make crash injuries
worse. That’s especially true for brain,
spinal cord and heart injuries. That means
that if anyone who has been drinking
-
driver or passenger - is in a crash, the
chance of being killed or permanently
disabled is higher than
if that person had
not been drinking. And we’ve already
seen that the chance of a crash itself is
higher for drinking drivers.
I‘
I Control of a Vehicle
ou have three systems that make your
2hicle go where you want it to go.
hey are the brakes, the steering and the
xelerator. All three systems have to do
teir work at the places where
the tires
teet
the road.
ometimes, as when you’re driving on
IOW or ice, it’s easy to ask more of those
mtrol systems than the tires and road
an provide. That means you can lose
mtrol of your vehicle.

Braking
3ralung action involves perception time
md reaction time.
%st, you have to decide to push
on the
)rake pedal. That’s perception time.
rhen you have to bring up your foot
md do it. That’s reaction time.
4verage reaction time is about
3/4 of a
;econd. But that’s only an average. It
might be less with one driver and as
long as two or three seconds or more
with another. Age, physical condition,
alertness, coordination, and eyesight all
play a part.
So do alcohol, drugs and
frustration. But even in
3/4 of a second,
a vehicle moving at 60 mph (100 km/h)
travels 66 feet (20 m). That could be a lot
of distance in an emergency, so keeping
enough space between your vehicle and
others is important.
And,
of course, actual stopping distances
vary greatly with the surface of the road
(whether it’s pavement or gravel); the
condition of the road (wet, dry, icy); tire
tread; and the condition of your brakes.
Avoid needless heavy braking. Some
people drive in spurts
- heavy
acceleration followed by heavy braking
- rather than keeping pace with traffic.

TCS
OFF
If your vehicle is in cruise control when
the traction control system begins to
limit wheel spin, the cruise control will
automatically disengage. When road
conditions allow you to safely use it
again, you may re-engage the cruise
control. (See “Cruise Control”
in the
Index.)
The “TCS
OFF” warning light will come
on when you turn the traction control system off. When the system is on, this
light will come on to let you know if
there’s a problem with your traction
control system. See “Traction Control System Warning Light”
in the Index.
When this warning light is on, the system
will not limit wheel spin. Adjust your
driving accordingly.

Your Driving and the Road
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.
Steering
Power Steering
If you lose power steering assist because
the engine stops or the system
is not
functioning, you can steer but it will
take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a
reasonable speed.
A lot of the “driver lost control” accidents
mentioned on the news happen on curves.
Here’s why:
Experienced driver or beginner, each of
us is subject to the same laws of physics
when driving on curves. The traction of
the tires against the road surface makes it
possible for the vehicle to change its path
when you turn the front wheels. If there’s
no traction, inertia will keep the vehicle
going in the same direction. If you’ve
ever tried to steer a vehicle on wet ice,
you’ll understand this.
The traction you can get in a curve
depends on the condition of your tires
and the road surface, the angle at which
the curve is banked, and your speed.
While you’re in a curve, speed is the
one factor you can control.
Suppose you’re steering through a sharp
curve. Then you suddenly accelerate.
Both control systems
- steering and
acceleration
- have to do their work
where the tires meet the road. Unless you
have traction control and the system is
on, adding the sudden acceleration can
demand too much of those places.
You
can lose control.
What should you do if this ever happens?
Ease up on the accelerator pedal, steer the
vehicle the way you want
it to go, and
slow down.
Speed limit signs near curves warn that
you should adjust your speed. Of course,
the posted speeds are based on good
weather and road conditions. Under less
favorable conditions you’ll want to go
slower.
[f you need to reduce your speed as you
approach a curve,
do it before you enter
the curve, while your front wheels are
straight ahead.
Try to adjust
your speed so you can
”drive” through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until you are out of the curve,
and then accelerate gently into the
straightaway.

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.
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 is best handled by
Easing your foot
off the accelerator pedal.
[f you have the traction control system,
remember:
It helps avoid only the
acceleration skid. If you do not have
traction control, or if the system is
off,
then an acceleration skid is also best
handled by easing your foot
off the
accelerator pedal.
If your vehicle starts to slide, ease your
bot off the accelerator pedal and quickly
steer the way you want the vehicle to
go.
If you start steering quickly enough, your
vehicle may straighten out. Always be
ready for a second skid
if it occurs.
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 recqgnize
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.

Your Driving and the Road
Hydroplaning
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.
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 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.
Some Other Rainy Weather Tips
Turn on your low-beam headlights -
not just your parking lights - to help
make
you more visible to others.
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.
Have good tires with proper tread
depth. (See “Tires” in the Index.)
City 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:
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 trip.
Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy. (See the next
section, “Freeway Driving.”)

Your Driving and the Road
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 thnk 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
clohng 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 Pontiac 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?
. . .I40
Wiper Blades: Are they m good
shape?
0 Fuel, Engine Oil, Other Fluids:
Have you checked all levels?
0 Lights: Are they all workmg? 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?
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?
Maps: Do you have up-to-date
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:
0
0
0 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 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. 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.
0 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. 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.
In hilly terrain, you may want to
switch to the
“PERFORMANCE”
mode for better performance.
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
you? 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.

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.
. . .I42
You may want to put winter
emergency supplies in your vehicle.
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.
ProCarManuals.com

Whatever the condition - smooth ice,
packed, blowing or loose snow
- drive
with caution. If you have traction control,
keep the system on. It will improve your
ability to accelerate when driving on a
slippery road. Even though your vehicle
has a traction control system, you’ll want
to slow down and adjust your driving to
the road conditions. See “Traction
Control System’’ in the Index. If you
don’t have the traction control
system, 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.
0
0
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.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be
in a serious situation. You should
probably stay with your vehicle unless
you know for sure that
you are near help
and you can hike through the snow. Here
are some things to do
to summon help and
keep yourself and your passengers safe:
Turn on your hazard flashers. Tie a red
cloth to your vehicle to alert police that
you’ve been stopped by the snow. 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.

NOTICE:
Pulling a trailer improperly can
damage your vehicle and result in
costly repairs not covered by your
warranty.
To pull a trailer correctly,
follow the advice in this section, and
see your Pontiac dealer for important
information about towing a trailer
with your vehicle.
Your vehicle can tow a trailer if it is
equipped with the proper trailer towing
equipment. To identify what the vehicle
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, transmission, rear axle, 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 You Do Decide to Pull a Trailer
If you do, here are some important points.
0 There are many different laws,
including speed limit restrictions,
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.
0 Consider using a sway control. You
can ask a hitch dealer about sway
controls.
0 Don’t tow a trailer at all during the
first 1,000 miles (1 600 km) your
new vehicle is driven. Your engine,
axle or other parts could be damaged.
(800 km) that you tow a trailer, don’t
drive over
50 mph (SO h/h) and don’t
make starts at full throttle. This heips
your engine and other parts of your
vehicle wear in at the heavier loads.
Obey speed limit restrictions when
towing a trailer. Don’t drive faster
than the maximum posted speed for
trailers (or no more than
55 mph
(90 km/h)) to save wear on your
vehicle’s parts.
Three important considerations have to do
with weight:
., )I
Weight of the .Trailer $:
How heavy can a trailer safelyabe?
It should never weigh more th&
1,500 pounds (680 kg) under nQrmal
driving conditions. It should n&er
weigh more than
1,000 pounds
(450 kg) when driven on long grades
at high ambient temperatures. But
even that can be too heavy.
