service reset BUICK PARK AVENUE 1993 Owners Manual

This light will also come on when you set your parking
brake, and the light will stay on if your parking brake
doesn’t release fully. If
you try to drive off with the
parking brake set, a chime will also come
on until you
release the parking brake. If the light and chime stay on
after your parking brake is fully released, it means
you
have a brake problem. If the light and chime come on
while driving, pull
off the road and stop carefully. You
may notice that the pedal is harder to .push. Or, the peda
may go closer to the floor. It may take longer
to stop. If
the light
is still on, have the vehicle towed for service.
(See “Towing Your Car” in the Index.)
I -
A CAUTION:
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake warning light on can lead to an accident.
If
the light is still on after you’ve pulled off the road
and stopped carefully, have the vehicle towed for
service.

Anti-Lock Brake System Warning Light
With anti-lock, this light will go on when you start your
engine and may stay on for several seconds or
so. That’s
normal. If the light doesn’t come on, have it fixed
so it
will be ready to warn
you if there is a problem.
If the light stays
on or comes on when you’re driving,
stop as soon as possible and turn the key
off. Then start
the engine
to reset the system. If the light still stays on,
or comes on again while you’re driving, your Buick
needs service. Unless the regular brake system warning
light
is also on, you will still have brakes, but not
anti-lock brakes.
If the regular brake system warning
light
is also on, see “Brake System Warning Light”
earlier
in this part.

“Change Oil Soon” Light (Option)
CHANGE
OIL SOON
This light is activated by
the Engine Oil Life
Monitor System. It
indicates that the engine oil
has degraded enough to
require changing. (See
“Engine Oil” in the Index).
This is determined by electronically monitoring engine
speed, coolant temperature and vehicle speed. Since the
change interval is dependent upon driving habits and
conditions, 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 three seconds as a
bulb check each time the ignition key is turned to the
RUN position. If an oil change is required, it will stay
on for
60 seconds each time the engine is started. 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 once
again,
to be lit for just the bulb check period of three
seconds.
The reset button is.inside this hole, which is under the
passenger’s side of the instrument panel, near the door.
With the ignition key in the
RUN position, but the
engine not started, use a pen to push the reset button,
holding
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.
