brakes but you will still have the use of manual brakes.
The power brakes will not be affected if the problem is
caused by a failed sensor. Have your vehicle serviced
immediately at your Cadillac dealership.
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and
it should be changed
within 200 miles. See “Engine Oil” and “Filter
Recommendations”
in the Maintenance Schedule booklet.
After an oil change, the Oil Life Indicator must be reset. See “Oil Life Indicator”
in the Index on how to reset it.
CHANGE TRANS FLUID - 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CJ3ECK BRAKE FLUID LEVEL - 37: This message
will display if the ignition is in the
RUN position to
inform the driver that the brake fluid level is low. Check
the brake reservoir level and add fluid as needed. Have
the brake system serviced by a Cadillac technician as soon
as possible. If the brake warning light is on, follow
the directions in that part.
CHECK COOLANT LEVEL - 02: This message will
appear when there is a low level
of engine coolant. Have
the cooling system serviced by a Cadillac technician as soon as possible.

A single chime will also sound when this message
is displayed.
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface.
A false CHECK OIL LEVEL message
may appear if the vehicle is parked
on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level
is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure the engine has been off for five
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See “Engine
Oil” in the Index.

Downloaded from www.Manualslib.com manuals search engine To help avoid hearing loss or damage:
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, Cadillac
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.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN or CLEAN
TAPE to indicate that you have used your tape player for
50 hours without resetting the tape clean timer. Each time
the cassette is cleaned, the
50 hour cassette timer should
be reset.
This is done by holding down the eject button
for three seconds until the
TAPE CLEAN message is
displayed. If you notice a reduction in sound quality,
try a
known good cassette to see if
it is the tape or the tape
player at fault.
If this other cassette has no improvement
in sound quality, clean the tape player.
Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub the
tape head as the hubs of the cleaner cassette turn. It is normal for the cassette to eject while cleaning.
Insert the
cassette at least six times to ensure thorough cleaning.

Downloaded from www.Manualslib.com manuals search engine 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.
Anti-Lock Brakes (ABS)
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 and 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.
ANTI -
LOCK
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.

Downloaded from www.Manualslib.com manuals search engine Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase.
A 50-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you
do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if you’re
driving, don’t wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take
a second or two, or even several
seconds, for your eyes to readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down
a little. Avoid staring
directly into the approaching headlamps. Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less
of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren’t even aware
of it. .

Downloaded from www.Manualslib.com manuals search engine City Driving
One of the biggest problems with city streets is the
amount of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals. Here
are ways to increase your safety in city driving:
0 Know the best way to get to where you are
going. Get
a city map and plan your trip into an
unknown
part of the city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy.
(See the
next part, “Freeway Driving.”)
Treat a green light as a warning signal. A traffic
light is there because the corner
is busy enough to
need it. When a light turns green, and just before you
start to move, check both ways for vehicles that have
not cleared the intersection or may be running the
red light.

Downloaded from www.Manualslib.com manuals search engine Freeway Driving
Mile for mile, freeways (also called thruways, parkways,
expressways, turnpikes or superhighways) are the safest of
all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the same
speed most of the other drivers are driving. Too-fast or
too-slow driving breaks a smooth traffic flow. Treat
the
left lane on a freeway as a passing lane. At the entrance, there
is usually a ramp that leads to the
freeway.
If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to
check traffic. Try to determine where you expect to
blend with the flow. Try to merge into the gap at close to
the prevailing speed. Switch on your
turn signal, check
your mirrors and glance over your shoulder as often as
necessary. Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate
if it’s slower. Stay
in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there isn’t another vehicle in your
“blind” spot.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance.
If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
