Downloaded from www.Manualslib.com manuals search engine Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that
are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed
in English.
A/C OFF FOR ENGINE PROTECTION - 16: This
message displays when the engine coolant becomes
hotter than the normal operating temperature.
To avoid
added strain on a hot engine, the air conditioning
compressor is automatically turned off
so that air
conditioned
air is not delivered. If the coolant
temperature returns to normal, you must select AC to
return to a normal A/C compressor operation.
If this
message continues to appear, have the system repaired
as soon as possible to avoid compressor damage.
APPLY BRAKE TO SHIFT - 46: This message will
appear if your vehicle is in PARK
(P) for about 15
seconds and the brake
is not pressed in. To remove this
message from the DIC display, hold the
OFF and the
blue (cooler) buttons on the digital cluster climate control panel for about five seconds. On the analog
cluster climate control panel, press the
OFF button (next
to the
MODE button) and the down arrow on the PASS
TEMP button for about five seconds. Hold the same two
buttons to display the message again.
BATTERY NO CHARGE - 07: This message will
appear if the battery
is not being charged. Have the
electrical system checked by your Cadillac dealership at
your earliest convenience.
BATTERY VOLTS HIGH - 08: This message shows
that the electrical charging system is overcharging (more
than
16 volts). To avoid being stranded, have the
electrical system checked by your Cadillac dealership.
You can reduce the charging overload by using the
accessories. Turn on the lamps and radio, set 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 DIC by pressing the INFORMATION
(INFO) button. The normal range is 11.5 to 15.5 volts
when the engine is running.
BATTERY VOLTS LOW - 06: 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 after driving a few miles and the message should
go out. 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.
To help the generator recharge the battery
quickly, you can reduce the load on the electrical system
by turning
off the accessories. You can monitor battery

Downloaded from www.Manualslib.com manuals search engine voltage on the DIC by pressing the INFORMATION
(INFO) button. The normal range is 11.5 to 15.5 volts.
BRAKE VACUUM PROBLEM - 10s: 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 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.
CHECK FUEL GAGE - 39: This message will appear
when the fuel supply
is less than four gallons (15.2 L)
and the display is turned off (digital clusters only).
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 PCM FAULT - 110: The circuit in the Powertrain
Control Module (PCM) has shorted or is loose when this
message appears. Have your Cadillac serviced by your
dealership at once.
REDUCED ENGINE POWER - 41: This message
informs the driver, that due to wheel slippage, your vehicle
is reducing engine power to compensate for the loss of
traction. Accelerating too fast, causing the tires to spin,
is
an example of when this message would display.
REMOVE KEY - 70: This message will appear when
the Personalized Automotive Security System
(PASS-Key 11) is unable to read the pellet on the
ignition key or an improper key pellet has been inserted.

STABILITY ENGAGED - 55: If you have the DeVille
Concours, you may see the STABILITY ENGAGED
message on the Driver Information Center. It means that
an advanced, computer-controlled system has come on
to help your Cadillac continue to go in the direction in
which you’re steering. This stability enhancement
system activates when the computer senses that your
Cadillac is just starting to spin, as it might if you hit a
patch
of ice or other slippery spot on the road. When the
system is on, you may hear a noise or feel a vibration in
the brake pedal. This is normal.
When the STABILITY ENGAGED message is on, you should continue to steer in the direction you want to go.
.
The system is designed to help you in bad weather or
other difficult driving situations by making the most of
whatever road conditions will permit. If the STABILITY
ENGAGED message comes on, you’ll know that something has caused your Cadillac to start to spin,
so you should consider slowing down.

Downloaded from www.Manualslib.com manuals search engine TRACTION ENGAGED - 91: When your traction
control system is limiting wheel spin, the TRACTION
ENGAGED message will be displayed. Slippery road
conditions may exist
if this message is displayed, so
adjust your driving accordingly. This message will stay
on for a few seconds after the traction control system
stops limiting wheel spin.
TRACTION OFF - 89: This message will be displayed
after the traction control has been turned off.

minutes, the traction control system will be available
again and the TRACTION READY message
will appear.
TRANS FLUID RESET - 48: With the engine not
running and the ignition on, press and hold the OFF and
rear defog buttons until the TRANS FLUID RESET
message appears on the DIC (between five and
20 seconds).
TRANSMISSION HOT - 112: This messages indicates
that the transaxle fluid in your vehicle is
too hot. Stop
and allow your vehicle to idle until it cools down or
until this message is removed.

Downloaded from www.Manualslib.com manuals search engine Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
Cadillac: Buckle up.
(See “Safety Belts” in the Index.)
Defensive driving really means “be ready for anything.”
On city streets, rural roads or freeways, it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Kear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough
following distance. It’s the best defensive driving
maneuver, in both city and rural driving. You never
know when the vehicle in front of you is going to brake
or turn suddenly.

Downloaded from www.Manualslib.com manuals search engine Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
go. They are the brakes, the steering and
the accelerator.
All three systems have to do their work
at the places where the tires meet the road.
Braking
Braking action involves perception time and reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s reaction time.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle. Average
reaction
time is about 3/4 of a second. But
that’s only
an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination and eyesight
all play a part. So do alcohol, drugs and
frustration. But even in
3/4 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And,
‘of course, actual stopping distances vary greatly
with the surface
of the road (whether it’s pavement or
gravel); the condition
of the road (wet, dry, icy); tire
tread; the condition
of your brakes; the weight of the
vehicle and the amount
of brake force applied.

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 Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly
an animal jumps out in
front
of you.
You slam on the brakes. Here’s what happens with
ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. The
anti-lock system can change the brake pressure faster
than any driver could. The computer
is programmed to
make
the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
