Downloaded from www.Manualslib.com manuals search engine A CAUTION:
When an air bag inflates, there is dust in the
air. This dust could cause breathing problems
for people with
a history of asthma or other
breathing trouble.
To avoid this, everyone in the
vehicle should get out
as soon as it is safe to do so.
If you have breathing problems but can’t get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window
or a door.
Your vehicle has a feature that will automatically unlock
the doors and
turn the interior lamps on when air bags
inflate
(if battery power is available). You can lock the
doors again and turn the interior lamps off by using the
door lock and interior lamp controls.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation. Additional windshield breakage
may also occur from the right front
passenger air bag.
Air bags are designed to inflate only once. After an
air bag inflates, you’ll need some new parts for your
air bag system. If you don’t get them, the air bag
system won’t be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for
your vehicle covers the need to replace other parts.
0 Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness of the system, when
the sensors are activated and driver’s safety belt
usage at deployment.

If you need more power for passing, and you’re:
0 Going less than 35 mph (55 M), push the
accelerator pedal about halfway down.
0 Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn’t seem to shift gears as you accelerate,
something may
be wrong with a transaxle system
sensor. If you drive very far that
way, your
vehicle can
be damaged. So if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND
(2) when you are driving less
than
35 mph (55 km/h) and OVERDRIVE (0)
for higher speeds. THIRD
(3): This
position is also used for normal
driving, however, it offers more power and lower fuel
economy than OVERDRIVE
(@).
Here are examples for using THIRD (3) instead of
OVERDRIVE
(a):
When driving on hilly, winding roads.
0 When towing a trailer, so there is less shifting
between gears.
0 When going down a steep hill.
SECOND
(2): This position gives you more power. You
can use
SECOND (2) on hills. It can help control your
speed as you go down steep mountain roads, but then
you would also want to use your brakes off and on.

I NOTICE:
r
Don’t shift into SECOND (2) unless you are going
slower than
65 mph (105 km/h), or you can
damage your engine.

a single wipe cycle. For more cycles, hold the band on
MIST longer.
LO or HI: Turn the band away from you to either LO
(low speed) or to HI (high speed), depending on the
wiper speed you want.
Rainsense Wipers (DeVille d’Elegance and
DeVille Concours
Only)
DELAY You can set the wiper speed for a long or short
delay between wipes with
this setting. Move the band to
the DELAY position. The closer you move it to
LO, the
shorter the delay. (DeVille Only)
OFF: Turn the band to OFF to turn off the wipers.
Be sure to clear ice and snow from the wiper blades
before using them.
If they’re frozen to the windshield,
carefully loosen or thaw them.
If the blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor.
A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload. This
moisture sensor is mounted on the passenger’s
interior side of the windshield behind the rearview
mirror and is used to automatically operate the wipers
by monitoring the amount of moisture that is on
the windshield.

The light sensor for the DRL and the twilight sentinel is
located in
the center of the front defogger grille. If you
cover the sensor, it will read “dark” and the lamps will
come
on.
Exterior Lighting Battery Saver
If the manual park lamp control has been left on, the
exterior lamps will
turn off approximately 10 minutes
after the ignition
is turned to LOCK or ACCESSORY
This protects draining the battery in case you have
accidently left the headlamps or parking lamps
on. If
you need to purposely leave the lamps on for more
than
10 minutes with the ignition in LOCK or ACC, turn the
manual control
knob off and then back on. To delay the
lamps from turning
off, see “Twilight Sentinel” earlier
in
this section.
Interior Lamps
Instrument Panel Brightness Control
Cluster lighting as well as instrument panel lighting
automatically dims when it becomes dark outside. When
it’s dark, the brightness control can be manually adjusted. Cluster lighting and instrument panel lighting
automatically brighten when it becomes light outside.

Downloaded from www.Manualslib.com manuals search engine Courtesy Lamps (DeVille Only)
The courtesy lamps are located in the roof in the rear
seat. These lamps come on with the lamp
knob or when
any door is opened and it is dark outside.
Illuminated Entry
The illuminated entry system turns on the courtesy
lamps and the backlighting to the door switches and to
the lamp control knob when a door is opened or if you
press a
RISE transmitter button. Since the illuminated
entry system has
a photocell, this means that it must be
dark outside in order for the courtesy lamps
or
backlighting to turn on. The courtesy lamps turn off
approximately 20 seconds after the last door is closed or
after the ignition key is placed in the ignition.
Parade Dimming
This feature prohibits the dimming of the instrument
panel lights during daylight while the headlamps are on.
This feature operates with the light sensor for the
twilight sentinel and is fully automatic. When the light
sensor reads darkness outside, the instrument panel
lights can be adjusted. Backlighting to the instrument
panel will
also turn on.
Reading Lamps (DeVille d’Elegance and
DeVille Concours Only)
The reading lamps are located in the roof. These lamps
come on when any door is opened and it is dark outside.
Press the button
to turn them on. Press it again to turn
them
off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

Downloaded from www.Manualslib.com manuals search engine Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system
for malfunctions. The light
tells you
if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
AIR BAG
This light will come on
when you start your engine, and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready. The
air bag readiness light should flash for a
few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.
Charging System Indicator Light
When you turn the key to
RUN, this light will come
on briefly
to show that
the generator and battery charging systems
are working.
If this light stays on, you need service and you should
take your Cadillac to the dealer at once.
To save your
battery until you get there, turn
off all accessories.
If the air bag readiness light stays on after you start the
engine or comes on when you
are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

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.
