2001 PONTIAC GRAND PRIX light

2-84 Oil Warning Light
United States Canada
If you have a problem with your oil pressure, this light
may stay on after you start your engine, or come on
when you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in two other situations:

When the ignition is on but the engine is not running,
the light will come on as a test to show you it's
working. The light will go out when you turn the
ignition to RUN. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.
If you make a hard stop, the light may come on for a
moment. This is normal.
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-85 Low Oil Level Light
The engine is equipped with
an oil level monitoring
system. When the ignition
key is turned to RUN, the
LOW OIL LEVEL light
will briefly flash.
If the light does not flash, have it fixed so it will be
ready to warn you if there is a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index).
The oil level monitoring system only checks the oil level
during the brief period when the ignition key is between
RUN and START. It does not monitor engine oil level
when the engine is running. Additionally, an oil level
check is only performed if the engine has been turned
off for a considerable period of time, allowing the oil
normally in circulation to drain back into the oil pan.
Security Light
This message is
displayed to monitor the
Pass
-Key
III system.
If the SECURITY message is displayed continuously
while driving, there may be a problem with the
Pass
-Key III system. Your vehicle will not be protected
by Pass
-Key III, and you should see your dealer for
service. For more information see ªPASS
-Key III

Systemº in the Index.

2-86 Fuel Gage
United States Canada
The fuel gage tells you about how much fuel you have
left when the ignition is on. When the indicator nears
empty, you still have a little fuel left, but you should
get more soon.
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.

2-87
Driver Information Center (DIC)
3100 V6 or 3800 V6 Engine Only
The Driver Information Center (DIC) gives you important safety and maintenance facts. When you turn the ignition
on, all of the DIC lights illuminate for a few seconds. After this, the DIC will begin working.

2-88 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
enhanced traction system is limiting wheel spin.
See ªEnhanced Traction Systemº or ªLow Traction
Lightº in the Index.
TRAC OFF: This light lets you know that the enhanced
traction 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 enhanced traction system,
you will have a disable button on the far right side of the
DIC. The enhanced traction system is automatically
activated when you turn the ignition on. This button will
activate/deactivate the 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.

Functions
FUEL USED: Shows the total amount of fuel used
since you last reset this mode. The amount can be
displayed in gallons or liters.
AVG ECON: Shows the average fuel economy since
you last reset this mode.
OIL LIFE: Shows a percentage of the oil's remaining
useful life. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. Each time you get an oil
change, be sure to reset this function so that it will give
you an accurate percentage. See ªHow to Reset the GM
Oil Life System
º 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.

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
enhanced traction system (3100 or 3800 V6 engine) or
the traction control system (3800 supercharged V6
engine) is limiting wheel spin. See ªTraction Control
Systemº ªEnhanced Traction Systemº and ªLow
Traction Lightº in the Index.

V6 engine) has been disabled and will not limit wheel
spin. See ªTraction Control System Warning Light,º
ªEnhanced Traction System Warning Lightº and
ªLow Traction Lightº in the Index.
TRAC/TCS: If the vehicle has the enhanced traction
system (3100 or 3800 V6 engine) or the traction control
system (3800 supercharged V6 engine), you will have a
disable button on the far right side of the trip computer.
The enhanced traction system and traction control
system are automatically activated when you turn the
ignition on. This button will activate/deactivate the
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.Head-Up Display (Option)
