2000 PONTIAC GRAND PRIX warning light

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

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 or pulses a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº 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.

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.)

4-10
To turn the system off,
press the TCS button on
the far right end of the
trip computer.
The traction control system warning light will come on
and stay on. If the system is limiting wheel spin when
you press the button, the warning light will come on and
the system will turn off instantly.
You can turn the system back on at any time by pressing
the button again. The traction control system warning
light should go off.Enhanced Traction System
(3100 V6 or 3800 V6 Engine)
Your vehicle may have an Enhanced Traction System
(ETS) 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.
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See ªEnhanced
Traction System Warning
Lightº in the Index.
If your vehicle is in cruise control when the enhanced
traction 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.)

4-11
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you've
chosen, so you should use the lower gears only when
necessary. See ªAutomatic Transaxleº in the Index.
This TRAC OFF warning
light will come on to let you
know if there's a problem.
See ªEnhanced Traction System Warning Lightº in the
Index. 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 Enhanced
Traction 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 ªRocking Your Vehicleº in the Index.)
To turn the system on or off,
press the TRAC button on
the far right end of the
Driver Information Center
(DIC) or the optional
trip computer.
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on.
If the Enhanced Traction System is limiting wheel spin
when you press the button to turn the system off,
the warning light will come on and the system will turn
off right away.
You can turn the system back on at any time by pressing
the button again. The Enhanced Traction System
warning light should go off.

Here are ways to increase your safety in city driving:

Know the best way to get to where you are going.
Get a city map and plan your trip into an unknown
part of the city just as you would for a
cross
-country trip.

Try to use the freeways that rim and crisscross most
large cities. You'll save time and energy. (See the
next part, ªFreeway Driving.º)

Treat a green light as a warning signal. A traffic light
is there because the corner is busy enough to need it.
When a light turns green, and just before you start to
move, check both ways for vehicles that have not
cleared the intersection or may be running the
red light.
Freeway Driving
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest
of all roads. But they have their own special rules.

4-27
Winter Driving
Here are some tips for winter driving:

Have your vehicle in good shape for winter.

You may want to put winter emergency supplies in
your trunk.
Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
