1997 PONTIAC PONTIAC brake light

The Trac System warning light may come on for the
following reasons:
If you turn the system off by pressing the TRAC
button, the warning light will come on and stay
on.
To turn the system back on, press the button again.
The warning light should go off. (See “Trac System”
in the Index for more information.)
The warning light will come on when you set your
parking brake with the engine running, and it will
stay
on if your parking brake doesn’t release fully. If
the system is turned on and the warning light stays
on after your parking brake is fully released, it
means there’s a problem with the system.
If the Trac System warning light comes on and stays on
for an extended period of time when th,e system is
turned on and the parking brake is fully. released, your
vehicle needs service.
Low Traction Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come
on.
If you have the Trac System, this light will also come on
when the system is limiting wheel spin. Slippery road
conditions may exist if the low traction light comes on,
so adjust your driving accordingly. The light will stay
on for a few seconds after the anti-lock system stops
adjusting brake pressure or the Trac System stops
limiting wheel spin.
The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come
on then, have it fixed
so it will be there to tell you when
the anti-lock brake system or Trac
System is active,

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.

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.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If
your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you
will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you
begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light” in the Index.

Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may feel the
system working, or you may notice some noise,
but this is normal.
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help
avoid a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
Trac System (Option: Not Available with
3800 Supercharged Engine)
Your vehicle may have Trac System that limits wheel
spin. This
is especially useful in slippery road
conditions. The system operates only if it senses that one
or both of the front wheels are spinning or beginning to
lose traction. When this happens, the system reduces
engine power and may also upshift the transaxle to limit
wheel spin.
LOW
TRAC
This light will come on
when your Trac System is
limiting wheel spin. See
“Trac System Active Light”
in
the Index. You may feel
or hear the system working,
but this is normal.
The Trac System operates in all transaxle shift lever
positions. But the system can upshift
the tran.saxle only
as high as the shift lever position you’ve chosen, so you
should use the lower gears only when necessary. See
“Automatic Transaxle” in the Index.

I TRAC
When the system is on and
the parking brake is fully
released, this warning light
will
come on to let you
know if there’s
a problem
with the system. See “Trac
System Warning Light” in
the Index.
To turn the system on or off,
press the TRAC button on
the on the far
right end of
the Driver Information
Center
or the optional
Trip Computer.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Trac System on.
But you can turn the system off if you ever need to.
(You should turn the system off
if your vehicle ever gets
stuck in sand, mud, ice
or snow. See “Rocking Your
Vehicle” in the Index.) When
you turn the system
off, the Trac System warning
light will come on and stay on. If the Trac System is
limiting wheel spin when you press the button to turn
the system off, the warning light will come on
-- but the
system won’t turn off right away. It will wait until
there’s no longer
a current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The Trac System warning light should
go off.

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.
