In many crashes sevefe 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 pr0tec.t 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.
@ Your vehicle has a crash sensing and diagnostic
__ module, which records information about the air bag
and related systems.
It records information about the
readiness
of the air bag systems, when the sensors
are activated and driver’s safety belt usage at
deployment or
in a near-deployment crash. Some
modules also record speed, engine
RPM and brake
and acceleration data.
Let only qualified technicians work on your air bag
systems. &proper service can mean that an
air bag
system won? work properly. See your dealer
for service.
NOTICE:
If you damage ,the covering for the driver’s or the
right front passenger’s
air bag, or the air bag
covering
on the driver’s and right front
passenger’s door, the bag may not work properly.
You may have to replace the air bag module
in
the steering wheel, both the air bag module and
the instrument panel for the right front
passenger’s air bag,
or both the air bag module ’
and door phel for the driver’s and right front
passenger’s side impact
air bag. Do not open or
break the
air bag coverings.

If you need more power for passing, and you’re:
Going less than 35 mph (55 kmk), push the
accelerator pedal about halfway down.
Going about 35 mph (55 kmh) 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 (a)
for higher speeds.-
THIRD (3): This position is also. used for normal
driving, however, it offers more power and lower fuel
economy than
OVERDRIVE (0).
Here are examples for using THIRD (3) instead of
OVERDRIVE (0):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
. 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 wbuld
also want to use your brakes off and on.
between gears.

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

Downloaded from www.Manualslib.com manuals search engine 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.
Rainsense Wipers (DeVille d’Elegance and
DeVille Concours Only)
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 Rainsense system can be activated by turning the
wiper stalk to one of the five sensitivity levels within the
AUTO DELAY area. The AUTO DELAY position
closest to
OFF is the lowest sensitivity setting. This
allows more water to collect on the windshield between
wipes. Rotating the stalk away from you to the other
AUTO DELAY settings increases the sensitivity
of the
system and frequency
of wipes. A single wipe will occur
each time you
turn the wiper stalk to a higher sensitivity
level.
An initial wipe occurs when you turn the ignition
on as a reminder that Rainsense is active. The windshield wipers
also remain in a “high park” position (the wipers
will stop on the windshield rather than their fully rested
position), even when the ignition is turned
off.

instrument panel lights can be adjusted. Backlighting to
the instrument panel will also turn
on.

shows that the electrical charging system is
overcharging (more than 16 volts). To avoid being
stranded, have the electrical system checked by your
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 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.
To help the

Downloaded from www.Manualslib.com manuals search engine Radio Personalization
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings for
AM and FM
presets, last tuned station, volume, tone and audio
source (radio, cassette or CD). The settings recalled by
the radio are determined by which remote keyless entry
transmitter
(“1” or “2”) was used to enter the vehicle.
The number on the back
of the remote keyless entry
transmitter corresponds to driver
1 or to driver 2. After
the unlock button is pressed on the remote keyless entry
transmitter and the ignition is in RUN, the radio settings
will automatically adjust to where they were last set by
the identified driver. The settings can also be changed by
briefly pressing the memory seat buttons
1 or 2 located
on the driver’s door. The new settings will be saved for
the driver.
Continual Variable -- Roac ing
Suspension (CV-RSS) (DeVille Concours Only)
The CV-RSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer controller used to control and monitor the
suspension system. The computer controller receives
inputs from various sensors to determine the proper
system response.
If the computer controller detects a
problem within the system, the Driver Information
Center (DIC) will display a SERVICE RIDE
CONTROL message.
If this message appears, have
your vehicle serviced at your dealership.
