you can turn it

quickly without removing either hand.
But you have to act fast, steer quickly,

This

The fact that such emergency situations
are always possible is a good
reason to
practice defensive driving at all times.

Your Driving and the Road
Off-Road Recovery
You may find sometime that your right
wheels have dropped
off the edge of a
road onto the shoulder while you’re
driving.
If the level of the shoulder is only
slightly below the pavement, recovery
should be fairly easy. Ease
off the
accelerator and then, if there is nothing
in the way, steer
so that your vehicle
straddles the edge of the pavement. You
can turn the steering wheel up to ‘/4
turn until the right front tire contacts
the pavement edge. Then turn your
steering wheel to go straight down the
roadway.
If the shoulder appears to be about four
inches (100 mm) or more below the
pavement, this difference can cause
154
problems. If there is not enough room
to pull entirely onto the shoulder and
stop, then follow the same procedures.
But
if the right front tire scrubs against
the side
of the pavement, do not steer
more sharply. With too much steering
angle, the vehicle may jump back onto
the road with
so much steering input
that it crosses over into the oncoming
traffic before you can bring it back
under control. Instead, ease
off again on
the accelerator and steering input,
straddle the pavement once more, then
try again.
Passing
The driver of a vehicle about to pass
another on a two-lane highway waits for
just the right moment, accelerates,
moves around the vehicle ahead, then
goes back into the right lane again.
A
simple maneuver?
Not necessarily! Passing another vehicle
on a two-lane highway is a potentially
dangerous move, since the passing
vehicle occupies the same lane as
oncoming traffic for several seconds.
A
miscalculation, an error in judgment, or
a brief surrender to frustration or anger
can suddenly put the passing driver face
to face with the worst of all traffic
accidents-the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road,
to the sides, and to crossroads for
situations that might affect your
passing patterns.
If you have any
doubt whatsoever about making a
successful pass, wait for a better time.

Your Driving and the Road
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 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 changes
could cause the tires to slide. You may
not realize the surface
is slippery until
your vehicle is skidding. Learn to
ProCarManuals.com

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.
If you have the anti-lock braking
system, remember: It helps avoid only
the braking skid.
If you do not have
anti-lock, then in a braking skid (where
the wheels are no longer rolling),
release enough pressure on the brakes
to get the wheels rolling again. This
restores steering control. Push the
brake pedal down steadily when you
have to stop suddenly. As long as the
wheels are rolling, you will have steering control. Steer the way you
want to go.
Driving at Night
Night driving is more dangerous than
day driving. One reason is that some
drivers are likely to be impaired-
by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively. Remember, this is
the most dangerous time.
Don’t drink and drive. (See the Index
under Drunken Driving for more on
this problem.)
Adjust your inside rearview mirror to
reduce the glare hom headlights
behind you.

Since you can’t see as well, you may
need to slow down and keep more

Drkjng 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
reguIar 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 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:

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 lm) 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,
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.
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.

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.

Another part of this manual tells how to
use your parking brake (see the
Index
under Parking Brake). But on a
mountain or steep hill, you can do one
more thing. You can turn your front
wheels to keep your vehicle
from rolling
downhill
or out into traffic.
Here’s how:

Drivjng 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
betw,een your tires and the road, you
can have a very slippery situation.
You’ll have a lot less traction or “grip’’
an’d 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, 0.C) and freezing rain begins to
fall. Try to avoid driving
on wet ice until
salt and sand crews can get there.
172
Whatever the condition-smooth ice,
packed, blowing or loose snow-drive
with caution. 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.
Unless you have the anti-lock braking
system, you’ll want to brake very gently,
too.
(If you do have anti-lock, see the
Index under Anti-Lock Brake System.
This system improves your vehicle’s
ability to make a hard stop on a slippery
road.) Whether you have the anti-lock
braking system
or not, you’ll want to
begin stopping sooner than you would
on dry pavement. Without anti-lock
brakes, if you feel your vehicle begin to
slide, let
up on the brakes a little. Push
the brake pedal down steadily to get the
most traction you can. Remember, unless you have anti-lock,
if
you
brake so hard that your wheels stop
rolling, you’ll just slide. Brake
so your
wheels always keep rolling and you can still steer.
Whatever your braking system, 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.

Do not tow a trailer if your vehicle is
equipped with a 3.4L (VIN Code X)
engine and a manual transaxle.
Your Pontiac can tow a trailer if it is
equipped with a
3.1L (VIN Code T)
engine or a 3.4L (VIN Code X) engine
and an automatic transaxle, and 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, 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.
All of that means changes in:
Handling
Durability
Fuel economy
If You 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
control.
Don’t tow a trailer at all during the
first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or
other parts could be damaged.
