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.

To help avoid hearing loss or damage:
FM stereo will give you the best sound. But FM signals
will reach only about 10 to
40 miles (1 6 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
The range for most AM stations
is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
AI Iudi Sy
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the
volume control on your radio to a safe
sound level before your hearing adapts to
it.
0 Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
~ Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, Delco radio
or other
systems, and even damage them. Your vehicle’s
systems may interfere with the operation
of
sound equipment that has been added
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear
out much faster if you
do a
lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you will use
it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push. Your vehicle has anti-lock brakes
(ABS). ABS is
an
advanced electronic braking system that will help
prevent a braking skid.
When you start’your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there’s a problem with the anti-lock brake system, this
warning light will stay
on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive
in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go.
If it needs
service, have
it done before starting out. Of course,
you’ll find experienced and able service experts in
Buick dealerships all across
North America. They’ll be
ready and willing
to help if you need it. Here
are some things
you can check before a trip:

Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?

Highway Hypn~s
Is there actually such a condition as “highway hypnosis”?
Or is
it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There
is something about an easy stretch of road with
the same scenery, along with the
hum of the tires on
the road, the drone of the engine, and the rush
of the
wind against the vehicle that can make you sleepy.
Don’t let it happen to you! If it does, your vehicle can
leave the road in
less than a second, and you could
crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here
are some tips:
0
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness
on the highway as
an emergency.
Hil lnd Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and
also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
A CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope. Coasting
downhill in
NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work
of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. Shift down to THIRD (3).
This will help cool your engine and transaxle, and
you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or an accident.
You may see highway
signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert
to these and take appropriate action.

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets
or extra clothing, make body
ins‘ulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep wm, but be careful. Snow can trap exhaust
gases under your vehicle:
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you.
You can’t see it or smell it, so you might not
know
it is in your vehicle. Clear away snow from
around the base
of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle
that’s away from the wind. This will help
keep
CO out.

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).
