Cruise Light - Buick 1999 LeSabre Owner's Manual

Change Oil Soon Light (If Equipped)
The CHANGE OIL SOON light turns on for three
seconds as a bulb check each time the ignition key is
turned to RUN. It will stay on for 60 seconds once
90 percent of the oil life has been used and each time the
engine is started after that. If the CHANGE OIL SOON
light is on continuously, there is a problem with the
Engine Oil Life Monitor System and service is required.
The Engine Oil Life Monitor determines the condition
of the engine oil and lets you know when the oil should
be changed. See "Engine Oil" in the Index.
The Engine Oil Life Monitor receives information about
engine speed, coolant temperature and vehicle speed to
determine how much the oil has degraded.
When to change your oil depends on your driving habits
and conditions. The CHANGE OIL SOON light may
turn on as early as 2,000 miles (3 218 km) or less for
harsh circumstances.
This light is activated
by the Engine Oil Life
Monitor System.
For additional information, see "Engine Oil, When to
Change" in the Index. To reset the Oil Life Monitor, see
"Engine Oil Life Monitor" in the Index.
