sensor BUICK PARK AVENUE 1997 Owners Manual

0 Air bags are designed to inflate only once. After they
inflate, 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.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the
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.
Let only qualified technicians work on your air
bag system. Improper service can mean that your
air bag system won’t 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, the bag may not
work properly. You may have to replace the
air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger’s air bag.
Do not open or
break the
air bag coverings.

Rain Sense Wipers (If Equipped)
This system automatically operates the wipers by
monitoring the amount of moisture on the windshield.
There is a sensor that controls the operation of this
feature mounted toward the passenger’s side windshield
interior, behind the rearview mirror.
The rain sense system is activated by turning the wiper
band to a position within the
DELAY area. You can set
the sensitivity level of the wipers by turning the wiper
band. The closer the wiper band is positioned to
LO, the
more sensitive the wipers are to rain. The closer it is positioned to
OFFMIST, the
less sensitive the wipers
are to rain.
If the wiper band is left in the DELAY area when the
ignition is turned
off, an initial wipe occurs when you
turn the ignition on as a reminder that the rain sense
feature
is active.
The rain sense wipers operate in a delay mode as well as
a continuous speed, depending on the amount of
moisture on the windshield and the sensitivity setting.
The MIST and wash cycles operate as normal and are
not effected by the rain sense function.
NOTICE:
To avoid wiper damage when using an automatic
car wash, turn the wiper band to
OFF to
disengage the rain sense feature.
It is important to note that the rain sense wiping feature
can be overridden at any time by manually turning the
wiper band
to LO or HI speed.
If the windshield on your vehicle ever needs
replacement, make sure that the new windshield
is rain
sense compatible.

Daytime Running 1 .rmps
Daytime Running Lamps (vrCL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
twilight sentinel,
so be sure it isn’t covered.
The
DRL system will make your high-beam headlamps
come on at reduced brightness in daylight when:
0 The ignition is on,
0 The headlamp switch is off and
0 The transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps will
be on. The parking lamps, taillamps, sidemarker and
other lamps won’t be on. Your instrument panel won’t
be lit up either. When
it’s dark enough outside, your high-beam
headlamps will change to low-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also
turn on. When it’s bright enough
outside, the regular lamps will turn
off, and your
high-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the
transaxle into PARK
(P). The DRL will stay off until
you shift out of PARK
(P).
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the twilight
sentinel control to the left into the detent in the slider
control. When released, the control will return to the
Twilight Sentinel minimum delay position and the lights
will turn
off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.

Twilight Sentinel Interior Lamps
Instrument Panel Intensity Control
Instrument panel light brightness can be adjusted by
rotating the headlamp
knob clockwise.
Twilight
Sentinel turns your
lamps on and
off by sensing
how dark
it is outside.
To control the exit
delay feature of Twilight
Sentinel, slide the control to
any position to vary the
lamp timeout.
If you move the control all the way to MAX, your lamps
will remain on for three minutes after you turn off your
engine.
If you move the control almost all the way in the
other direction,
so it’s just on, the lamps will go off
quickly when you
turn off your engine. You can
change this delay time from only a few seconds to
three minutes.
Light Sensor
Your twilight sentinel and daytime running lamps work
with the light sensor on top of the instrument panel.
Don’t cover it up. If you do
it will read “dark” and the
headlamps will come on.
Courtesy Lamps
When any door is opened, several lamps go on. They
make it easy for
you to enter and leave the car. You can
also turn these lamps on by rotating the headlamp knob
clockwise all the way past the detent.
Delayed Entry Lighting
When you open the door, the interior lamps will come
on. When you close the door with the ignition
off, the
interior lamps will stay on for
25 seconds or until the
ignition is turned to an on position. Please note that
locking the doors with the power door lock switch will
override the delayed entry lighting feature and the lamps
will turn off right away.
NOTE: Using the remote keyless entry transmitter to
lock the door will not cancel delayed lighting.

Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your 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, you will be able to dim
your instrument panel displays once again.

need service, and you should take your Buick
to the
dealer at once. To save your battery until you
get there,
turn off all accessories and turn
off your climate
control system.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you
replace a bad fuse with a new one of the identical size
and rating.
There are three fuse blocks in your vehicle: the
Instrument Panel Fuse Block located under the
instrument panel, the Underhood Fuse Block located on
the passenger’s side engine compartment, and the Rear
Fuse Block located under the rear seat.
Instrument Panel Fuse Block
The right side fuse panel is located under the
instrument panel.
Remove the hush panel to reveal the fuses.
To remove
the panel, remove the three screws located along the
rear edge of the panel. Place the wide end
of the fuse
puller over the plastic end
of the fuse. Squeeze the ends
over the fuse and pull it out.
>pare fuses are located
in the empty slots shown on the
following chart. When finished, replace
the hush panel. Replace lamps,
