2000 PONTIAC GRAND PRIX warning

2-83
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not indicate
a problem with the fuel gage:

At the gas station, the pump shuts off before the gage
reads full.

It takes more (or less) fuel to fill up than the gage
indicates. For example, the gage reads half full, but it
took more (or less) than half the tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate full when the ignition
is turned off.Low Fuel Light
If your fuel is low, the
warning light near the fuel
gage will go on.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working
properly. If it doesn't come on then, see your dealer
for service.

Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the Head-Up
Display (HUD), you can see
the speedometer reading
(in English or metric units)
and a brief display of the
current radio station or CD
track, displayed ªthroughº
the windshield.The HUD also shows these lights when they are lit on
the instrument panel cluster:

Turn Signal Indicators

High
-Beam Indicator Symbol

Low Fuel Symbol
The HUD will display ªCHECK GAGEº when the
following items are lit on the instrument panel cluster:

Oil Warning Symbol

Coolant Temperature Symbol

Charging System Symbol
When you sit straight in your seat, the HUD image will
appear straight ahead near the front bumper.
When the ignition key is turned to RUN, the HUD
image will come on. Then the Head
-Up Display will
operate normally.

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.

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.

4-7
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.
