the climate control on AUTO and the fan speed on HI,
and turn the rear window defogger on.
You can monitor
battery voltage on the Driver Information Center (DIC)
by pressing the
INFO button. The normal range is
11.5 to 15.5 volts when the engine is running.
BATTERY VOLTAGE LOW - 6: This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting,
it is possible
that the generator can still recharge the battery. The
battery should recharge and may take a few hours to do
so. Consider using an auxiliary charger to boost the
battery after returning home or to a final destination.
(Be sure to follow the manufacturer’s instructions when
recharging the battery.)
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
to determine the cause of this problem.

the load on the electrical system by turning
off the
accessories. You can monitor battery voltage on the Driver Information Center (DIC) by pressing the
INFORMATION
(INFO) button. The normal range is
11.5 to 15.5 volts.
BRAKE VACUUM PROBLEM -108: The circuit in
the brake booster vacuum has shorted or is loose when
this message appears. Your vehicle may lose power
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 dealership.
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and it should be changed
within
200 miles (322 km). See “Engine Oil” and “Filter
Recommendations’’ in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must be reset. For more information, see “How to Reset the

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.
2.
3.
4.
5.
Apply your regular brakes, but do not shift into
PARK (P).
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load. Reapply the regular brakes. Then shift into
PARK
(P) firmly and apply your parking brakes.
Release the regular brakes.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have s‘6~1&@kt pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule booklet
for more
on this. Things that are especially important in
trailer operation are automatic transaxle fluid (don’t overfill), engine oil, drive belt, cooling system and brake
adjustment. If you’re trailering, it’s a good idea to
review these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want
to use the proper Cadillac Service Manual. It tells
you much more about how to service your vehicle than
this manual can.
To order the proper service manual,
see “Service and Owner Publications’’ in the Index.
Your vehicle has
an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vshicle” in the Index.

Downloaded from www.Manualslib.com manuals search engine Automatic Transaxle Fluid
Operating the engine with the air cleaner off can
cause you or others to be burned, The air cleaner
not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned, Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfke can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under
one or more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain. regularly reaches
90°F (32°C) or higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
0 Use such as limousine service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require change
until
the message CHANGE TRANS FLUID appears
on the Driver Information Center.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads’are worn and new pads are needed.
The sound
may come and go or be heard all
the time your vehicle
is moving (except when you are pushing on the brake
pedal firmly).
r
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires
are rotated, inspect
brake pads for wear and evenly torque wheel nuts in
the proper sequence to
GM specifications.
Brake linings should always be replaced as complete axle sets.
See “Brake System Inspection” in the Maintenance
Schedule booklet under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 rriiles
(10 000 to 13 000 krn). Any time you notice unusual
. wear, rotate your tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation
is to achieve more
uniform wear for
all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here. Don’t include the compact spare tire
in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that
all wheel nuts
are properly tightened. See “Wheel Nut Torqoe” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come
off and cause
an accident. When you change
a wheel, remove
any rust
or dirt from places where the wheel
attaches to the vehicle.
In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get all the rust or dirt
off. (See ’ .
“Changing a Flat Tire” in the Index.)

Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example,, a tire graded
150 would wear one and a
half
(1 1/2) times as' well on the governmefit course
as a tire graded
100. The relative performance of
tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices
and differences in road characteristics and climate.
Traction -- AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
1 conditions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor
I traction performance.
.~ ~~~~~ ~ ~~~~~ ~
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade
C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is
,established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
1 Warning: The traction grade assigned to this tire is based
on braking (straight ahead) traction tests and does not
include acceleration, cornering, hydroplaning, 'or peak
traction characteristics.
Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of
