Check Tire Pressure Light
CHECK
TIRE
PRESS
With the check tire pressure
system, after you’ve driven
10 to 20 miles (1 5 to 30 km)
the CHECK TIRE PRESS
light will come on if the
pressure in one tire becomes
at least
10 psi (69 kPa)
higher or lower than the
other three tires.
When
the CHECK TIRE PRESS light comes on, you
should stop
as soon as you can and check all your tires
for damage.
(If a tire is flat, see “If a Tire Goes Flat’’
in the Index.) Also
check the tire pressure in all four
tires
as soon as you can. See ‘‘Inflation - Tire Pressure
in the Index.
The light will stay on until you turn off the ignition or
press the
CALIBRATE TIP9 PRESS button. See
“Check Tire Pressure Syst?
.” in the Index.
If the anti-lock
brake system warning light comes on
with the CHECK
TIRE PRESS light, the check tire
pressure system isn’t working. See your Pontiac dealer
for service.
(Also, see “Anti-Lock Brake System
Warning Light in the Index.)
Mal€unctisn Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENIGINIE SOON
Your Pontiac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to assure
that emissions are at acceptable levels for the life of the
vehicle, helping to produce a cleaner environment. (In
Canada,
OBD I1 is replaced by Enhanced Diagnostics.)
The SERVICE ENGINE SOON light comes on to
indicate that there is
a problem and service is required.
Malfunctions often will be indicated
by the system before
any problem
is apparent. This may prevent more serious
damage to
your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where
the tires meet the road.
Sometimes,
as when you’re driving on snow or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means
you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and
do it. That’s reaction time.
Average reaction time is about 3/4 of a second. 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; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.

Braking in Emergencies
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.
Variable Effort Steering (Option)
This steering system provides lighter steering effort
for parking and when driving at speeds below
20 mph
(32 km/h). Steering effort will increase at higher speeds
for improved road
feel.
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 eva
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 the Trac System
and the system is on, adding
the sudden acceleration can
demand too much
of those places. You can lose control.
Refer to “Trac System” in the Index.
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.

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.
If you have the Trac System, remember: It helps avoid
only the acceleration skid. If
you do not have the Trac System, 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 foot 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 slud
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 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 brake system (ABS) helps
avoid only the braking skid.

You can be temporarily blinded by approaching
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 Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn
as well because
your tire-to-road traction isn’t as good as on dry roads.
And, if your tires don’t have
much tread left, you’ll get
even less traction. It’s always wise to
go slower and be
cautious if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes
are
tuned for driving on dry pavement.

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 do not have 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.
Driving Through Deep Standing Water
I NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
I
Some Other Rainy Weather .-r~s
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.)

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.
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 t’end 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
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:

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 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.
