“Change Oil Soon” Light (Option)
CHANGE
OIL SOON
This light is activated by
the engine oil life monitor
system. The system
determines the condition
o
the engine oil and lets you
know when the oil should
be changed. (See “Engine
Oil” in the Index).
It does this using information about engine speed (revolutions per minute), coolant temperature and
vehicle speed. The system uses this data to determine
how much oil has degraded. 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 Oil Life
Monitor System and service is required.
After changing the engine oil, the system should be
reset.
This will cause the “Change Oil Soon” light to be
lit again for#the bulb check period
of three seconds.
When to change your oil depends on driving habits and
conditions because these directly affect engine speed,
coolant temperature and vehicle speed. Because of this,
the “Change Oil Soon” light may come on as early as
2,000 miles or less for harsh conditions.
The “Change Oil
Soon” light is lit for five seconds as a
bulb check each time the ignition key is turned to the
RUN position. It will stay on for 60 seconds once 90%
f
The reset button is in the glove box. With the ignition
key in the
RUN position push the reset button, hold it in
for at least
5 seconds but not more than 60 seconds.
After
5 seconds, the “Change Oil Soon” light will flash
4 times and then go off. This indicates that the Oil Life
Monitor System has been reset.

Engine Oil Additives
Don’t add anything to your oil. Your Buick dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less
than
10 miles (16 km).
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Soon” in the Index.) If
none of
them is true, change the oil every 7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change the filter at the first oil change and at every
other oil change after that.
If the optional “Change Oil Soon” light comes on you
will need to change your oil sooner than either mileage
specified. Depending upon driving habits, the “Change
Oil Soon’’ light may come on
as early as 2,000 miles or
less from the last time the oil life monitor was reset (See
“Oil Life Monitor” in the Index.)
Always reset the oil
life monitor after every oil change.
Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0°F (- 18 “C) or
colder. If your vehicle has this option, see “Engine
Coolant Heater” in the Index.
