Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if the fuel
cap has been left
off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water? If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to
do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow
the previous steps, and drive the vehicle to your
dealer or qualified service center for service. If
so, your electrical system may be wet.
The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out
of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?

Downloaded from www.Manualslib.com manuals search engine If so, be sure to fuel your vehicle with quality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank
of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle.
Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to
ON or
START. It goes
off once you start your engine. That’s a
check to be sure the light works. If it doesn’t come on,
be sure to have it fixed
so it will be there to warn you if
something goes wrong.
When the light
comes on and stuys on, it means
that oil isn’t flowing through your engine properly.
You
could be low on oil and you might have some other
system problem.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Continuous Variable Road Sensing
Suspension (CVRSS)
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control
is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response. If
the
controller detects a problem within the system, the DIC
will display a SERVICE SUSPENSION SYS message.
If this message appears, have your vehicle serviced at
your dealership.
Driver Information Center (DIC)
This display gives you the status of many of your
vehicle’s systems. The DIC is also used to display driver
personalization features and warninghtatus messages.
Memory and Personalization Features
(If Equipped)
Your vehicle may have memory personalization.
Memory settings that have been previously programmed (HVAC settings, radio preset settings, exterior lighting
choices, remote confirmation choices, seat positions,
column positions,
mirror and programmable automatic
door lock choices) can be recalled by pressing the
unlock button on the
RKE transmitter or by placing the
key
in your vehicle’s ignition.
To begin programming, the ignition must be in ON, your
vehicle in PARK
(P), and if your vehicle has memory,
press the appropriate memory button
“1” or “2”, located
on the driver’s door panel, prior to programming. Press
the

appears immediately after starting, it
is possible that the
generator can still recharge the battery. The battery should recharge while driving but may take a few hours
to do
so. Consider using an auxiliary charger (be sure to
follow the manufacturer’s instructions) to boost the
battery after returning home or to a final destination. 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.

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

to go in the direction in which you’re
steering. This stability enhancement system activates
when the computer senses that your vehicle 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 SYS 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

Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in
a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling discs. Pick up discs by grasping the outer edges or the
edge
of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk
of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Diversity Antenna System
Your AM-FM antennas are located in the front
windshield and rear window. Be sure that the inside
surfaces of the front windshield and rear window are
not scratched and that the lines on the glass are not
damaged.
If the inside surfaces are damaged, they
could interfere with radio reception.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that
is sharp. This may damage
the rear defogger grid and affect your radio’s
ability
to pick up stations clearly. The repairs
wouldn’t be covered by your warranty.
If, when you turn on your rear window defogger, you
hear static on your radio station, it could mean that a
defogger grid line has been damaged. If this is true, the
grid line must be repaired.
If you choose to add an aftermarket cellular telephone to
your vehicle, and the antenna needs to be attached to
the
glass, be sure that you do not damage the grid lines for
the AM-FM antennas or place the cellular telephone
antenna over the grid lines.

Downloaded from www.Manualslib.com manuals search engine 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
Cadillac 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:
0 Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
a
0
0
0
Lamps: Are they all working? Are the lenses clean?
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?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
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.
