2000 PONTIAC GRAND PRIX traction control

2-49 Windshield Washer
At the top of the multifunction lever, there's a paddle
with the word PUSH on it. To spray washer fluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your
preset speed. See ªWindshield Washer Fluidº in
the Index.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When you apply the brakes, the cruise control shuts off.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control.
Don't use cruise control on slippery roads.

2-50
If your vehicle is in cruise control when the traction
control system on the 3800 Supercharged V6 engine
or the enhanced traction system on the 3100 V6 and
3800 V6 engine begins to limit wheel spin, the cruise
control will automatically disengage. (See ªTraction
Control Systemº or ªEnhanced Traction Systemº in the
Index.) When road conditions allow you to safely use it
again, you may turn the cruise control back on.
Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
Resuming a Set Speed
Suppose you set the cruise control at a desired speed and
then you apply the brake. This, of course, shuts off the
cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more
again, you can move the cruise control switch from
ON to R/A (Resume/Accelerate) briefly. You'll go right
back up to your chosen speed and stay there.

2-74 Traction Control System Warning Light
(3800 Supercharged V6 Engine Only)
The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the TCS
button located on the far right side of the trip
computer, 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
ªTraction Control Systemº in the Index
for more information.)

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Enhanced Traction System Warning Light
(3100 V6 or 3800 V6 Engine)
The Enhanced Traction System warning light may come
on for the following reasons:

If you turn the system off by pressing the TRAC
button on the far right side of the Driver Information
Center or trip computer (if equipped), 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 ªEnhanced Traction Systemº in
the Index for more information.

2-75

If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
Low Traction Light
If you have the
Enhanced Traction
System or the Traction
Control System, this
light will also come on
when the system is
limiting wheel spin.
You may feel or hear the system working, but this is
normal. 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 Enhanced Traction System or the Traction
Control System stops limiting wheel spin. See
ªEnhanced Traction Systemº or ªTraction Control
Systemº in the Index.
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 Traction Control System or Enhanced Traction
System is active.

2-89 Functions
: If one of the doors is ajar, this light will
appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it's time for an oil change. 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 the vehicle's driving
conditions. After changing the oil, the system must be
reset. See ªHow to Reset the GM Oil Life System
º in
the Index.
LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.LOW TRAC: This light will come on when the traction
control system is limiting wheel spin. See ªTraction
Control Systemº or ªLow Traction Lightº in the Index.
TRAC OFF: This light lets you know that the traction
control system has been disabled and will not limit
wheel spin. See ªEnhanced Traction System Warning
Lightº or ªLow Traction Lightº in the Index.
TRAC: If the vehicle has the traction control system,
you will have a disable switch on the far right side of the
DIC. The traction control system is automatically
activated when you turn the ignition on. This switch will
activate/deactivate the traction control system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.

2-93
RANGE: Shows how much farther you can travel with
the fuel you have before refueling. When the range
displays ªLº, for 40 to 50 miles (64.36 to 80.45 km),
the display will flash the word LOW continuously and
the vehicle will chime three times. The range is
calculated from the average econ value times the fuel
remaining in the tank.
LOW: This light will come on when the ignition is on
and the fluid in the washer fluid container is low.
DOOR AJAR: If one of the doors is left ajar, a light
will appear next to that door on the vehicle outline.
BOOST GAGE: If you have the 3800 V6 supercharged
engine, this gage will show the amount of boost the
engine is receiving.
TRUNK AJAR: If the trunk is not fully closed or open,
a light will outline the trunk area on the vehicle outline.LOW TRAC: This light will come on when the traction
control system is limiting wheel spin. See ªTraction
Control Systemº or ªLow Traction Lightº in the Index.
TRAC/TCS OFF: This light lets you know that the
traction control system has been disabled and will not
limit wheel spin. See ªTraction Control System Warning
Lightº or ªLow Traction Lightº in the Index.
TRAC/TCS: If the vehicle has the traction control
system, you will have a disable switch on the far right
side of the trip computer. The traction control system is
automatically activated when you turn the ignition on.
This switch will activate/deactivate the traction control
system. If you need to disable the system, such as when
you are stuck and are rocking the vehicle back and forth,
push this switch. See ªStuck: In Sand, Mud, Ice or
Snowº in the Index.

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. (Also see ªTraction Control Systemº
and ªEnhanced Traction Systemº in the Index.)
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.

4-9
Traction Control System
(With 3800 Supercharged V6 Engine)
Your vehicle has a traction control 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 works the
front brakes and reduces engine power to limit
wheel spin.
This light will come
on when your traction
control system is
limiting wheel spin.
See ªTraction Control
Warning Lightº in
the Index.
You may feel or hear the system working, but this
is normal.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
reengage the cruise control. (See ªCruise Controlº
in the Index.)
This light should come on
briefly when you start the
engine. If it stays on or
comes on while you are
driving, there's a problem
with your traction
control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control 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 ªRocking Your Vehicleº
in the Index.)
