2002 PONTIAC GRAND PRIX engine

2-89 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.

This message is
displayed to monitor the

by Pass
-Key III, and you should see your dealer for
service. For more information see ªPASS

(Door Ajar): 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 data 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.

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 (Low Traction): 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 (Traction 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.

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.

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 remaining in the gas tank before
refueling. When the range displays L, for 40 to 50 miles
