Turn Signal and Lane Change Indicator
The turn signal has two upward (for right) and two,
downward (for left) positions. These positions allow you
to signal a turn or
a lane change.
To signal a turn, move the lever all the way up
or down. When the turn is finished, the lever
will
return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
As you signal a turn or a lane change, if the arrows don’t
flash but just stay on, a signal bulb may be burned out
and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you
signal a
turn, check the fuse (see “Fuses’ and Circuit
Breakers” in the Index) and for burned-out bulbs.

If you have a trailer towing option with added wiring for
the trailer lamps,
a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if
a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly
to make sure they
are working.
lbm Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal.
To turn off the chime, move the turn signal lever
to the
off position. When the
high beams are
on, a light on the instrument
panel will also be on.
Headlamp High/Low Beam Changer
To change the headlamps from low beam to high or
high to low, pull the
turn signal lever toward you, then
release it.

Lamp Monitors (Option)
This system will let you know when certain exterior
lamp bulbs fad. When you start your car, all eight lamps
come
on briefly to show that'the system is working.
When a bulb
fails, an indicator will flash for several
seconds and then
stay on until the failed bulb is replaced
and lit.
For example, if a burned out back-up,lamp bulb
is replaced, the indicator for back-up lamps will stay on
until the transaxle is put in REVERSE (R) with the
ignition
ON. The bulbs are monitored only while they
are being used.
If you.have recently had a low battery condition or the
battery has been disconnected and reconnected, the
indicators
will flash when you turn the ignition switch to
RUN. Turning on the parking lamps will return the lamp
monitor system to normal operation.

Low Coolant Warning Light
COOLANT
LOW
When this light comes on,
the cooling system is
low on
coolant. As a bulb check, it
will come on when the
ignition in the
RUN
position and then go off.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your Buick is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
If the coolant level is low, the light will come back on. If
this happens, see “Engine Coolant” in the Index for
proper cooling system fill.
After the coolant level
is returned to its proper level, the
LOW COOLANT light will go off after
20 seconds or
remain
off on the next ignition cycle. This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The CHECK ENGINE light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent, which may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

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.
Check Oil Level Light (Option)
CHECK
OIL LEVEL
The CHECK OIL LEVEL
light comes on for three
seconds as a bulb check
each time the ignition key is
turned to the
RUN position.
If the light doesn’t come on,
have your vehicle serviced.
If the engine oil is more than one quart low, the light
will come on briefly, then go off for
15-25 seconds, and
then come back on for
20-40 seconds.
However, the system will not register low engine oil if it
has not been more than eight minutes since the engine
was last shut off.
If the CHECK OIL LEVEL light comes back on, the
engine oil should be checked at the dipstick then
brought up to the proper level if necessary. See “Engine
Oil” in the Index.

Change Oil Soon Light (Option)
CHANGE
OIL SOON
This light is activated by the
Engine Oil Life Monitor
System. The system
determines the condition of
the engine oil and lets you
know when the oil should be changed. (See “Engine
Oil” in the Index.)
It does this by using information about engine speed
(revolutions per minute), coolant temperature and
vehicle speed. The system uses this data to determine
how much the oil has degraded. 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 comes on 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% 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.

Tbrn Signals When Towing a Trailer
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about
to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still
working.
Your vehicle
has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out.
So, when you have a trailer
lighting system plugged in, be sure
to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps
is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade,
shift down to THIRD (3) and
reduce your speed to around
45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can
be damaged.
But if you ever have to park your rig on a hill, here’s
how
to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
5. Release the regular brakes.
brake, and the shift
to PARK
(P).

side
of the rear of the trunk
are two plastic nuts.
Remove only the side that
you need to access. Pull the
carpet back away from the
rear area. The taillamp,
sidemarker and back-up
lamps can now be accessed.
