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.)

(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.

Functions
CHANGE OIL SOON: This light will appear when the
system predicts that the oil’s remaining useful life
is
almost up. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm, and vehicle speed. It alerts you to change
the oil on a schedule consistent with your vehicle’s driving conditions.
To reset your change oil soon system after an oil change,
turn the key to the
ON position, without the engine
running and pump the accelerator
3 times within
5 seconds.
LOW WASHER FLUID: This light will come on when
your ignition is on and the fluid container is low.
CHECK TIRE PRESS: This light alerts you that a tire
is low or flat. See “Check Tire Pressure Light” in
the Index.
TRUNK A JAR: This light alerts you that your trunk is
not fully closed.
DOOR AJAR: If one of your doors is left ajar, a light
will appear next to that door on the vehicle outline.
TRAC SWITCH: If your vehicle has the Trac System
(this is not available with the
3800 Supercharged
engine), you will have
a disable switch on the far right
side of your Driver Information Center.
Your Trac
System is automatically activated when you turn the
ignition on. This switch will activate/deactivate the Trac
System.
If you need to disable the system, such as when
you
are stuck and are rocking your vehicle back and
forth, push this switch. See “Stuck: In Sand, Mud, Ice or
Snow” in the Index.

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. The
anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and
road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

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.

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:

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 Furecasts: 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?

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 headlamps. 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. 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.

Two labels on your vehicle show how much weight it
may properly
carry. The Tire-Loading Information label
is on the inside of the trunk lid. The label tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle.
It also gives you
important information about the number of people that
can be in your vehicle and the total weight you can
carry. This weight is called the vehicle capacity weight
and includes the
weight of all occupants, cargo and all
nonfactory-installed options.

If a Tire Goes Flat
10. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out
of the
filler neck, reinstall the pressure cap. Be sure the
mows
on the pressure cap line up like this.
11. Check the coolant in the recovery tank. The level
in the coolant recovery tank should be at the HOT
mark when the engine is
hot or at the COLD mark
when the engine is cold. It’s unusual for
a tire to “blow out”
while you’re driving,
especially
if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
slud and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and
noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a
flat tire safely.
