Buick Century - 1997 Fuse Box Diagram

Buick Century - 1997 Fuse Box Diagram

I1
Your vehicle is equipped
with the PASS-Key I1
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key I1
is
a passive
theft-deterrent system. It
works when you insert or
remove the key from
the ignition.
PASS-Key I1 uses a resistor pellet in the ignition key
that matches
a
decoder in your vehicle.
When
the PASS-Key
I1 system
senses
that
someone
is
using
the
wrong
key,
it shuts
down
the
vehicle’s
starter
and
fuel
systems.
For
about
three
minutes,
the
starter
won’t
work
and
fuel
won’t go to the
engine.
If
someone
tries
to
start
your
vehicle
again or uses
another
key
during
this
time,
the
vehicle
will
not
start.
This
discourages
someone
from randomly
trying
different keys with
different
resistor
pellets
in
an
attempt
to
make
a
match.
The ignition
key
must
be
clean
and
dry
before
it’s
inserted
in
the
ignition or the
enginemay
not
start. If
the engine
does
not
start
and
the
SECURITY
light
is flashing,
the key
may be dirty or wet.
Turn
the
ignition
off.
Clean and dry the key.
Wait about
three minutes and
try
again. If the starter still won’t work, and the key appears
to
be
clean
and dry, wait about three minutes and try
another ignition key. At this
time, you
may also want to
check the fuse (see “Fuses and Circuit Breakers’’ in the
Index). If the starter won’t work with the other key, your
vehicle needs service.
If
your vehicle does start, the
first
ignition key may
be faulty. See your Buick dealer or a
locksmith who can service the PASS-Key
11.
If
you accidentally
use
a
key that has a damaged or
missing resistor pellet, the starter won’t work and the
SECURITY light will come on. But you don’t have to
wait three minutes before trying another ignition key.
See your Buick dealer or a locksmith who can service
the PASS-Key
I1
to have a new key made.
If you’re ever driving
and
SECURITY
light
comes
on,
you
will be able
to
restart
your
engine if
you
turn
it
off.
Your
PASS-Key
I1 system,
however, is not
working
properly
and
must
be
serviced by your
Buick
dealer.
Your
vehicle
is
not
protected by the
PASS-Key
II
system.
If
you lose
or damage a PASS-Key
I1
ignition key,
see
your Buick dealer
or a locksmith who can service the
PASS-Key I1 to have a
new key made.
To
signal
a
lane
change,
just
raise or lower the lever
until the arrow starts
to
flash. Hold
it
there
until
you
complete your lane
change.
The
lever will return by
itself when you release
it.
As
you signal
a turn or
a
lane
change,
if
the arrow
flashes
faster than normal, a signal bulb may
be burned
out
and other
drivers won’t see your turn signal.
If
a
bulb is burned out,
replace
it
to help avoid an
accident. If
the
arrows don’t go
on
at all when you
signal a turn, check for burned-out bulbs and then check
the fuse (see “Fuses and Circuit Breakers’’
in
the
Index).
A
chime will sound
if
you leave your turn signal on for
more than
3/4
mile
(1.2
km).
Headlamp
High/Low
Beam
To
change your headlamps
from low beams to high
beams, or
high
to
low, pull
the multifunction lever all
the way toward you. Then
release
it.
When
the
high
beams are on,
a light on
the
instrument panel
also
will
be on.
Flash-to-Pass
Feature
This
feature lets you
use your high-beam headlamps
to
signal the driver
in
front
of
you
that you want
to
pass. It
works even if your headlamps are
off.
To
use
it,
pull
the
turn
signal lever toward you a little,
but
not
so
far that you hear
a
click.
If
your headlamps are off
or
on low beam, your
high-beam headlamps will turn
on.
They’ll stay on as
long as you hold the lever toward you and the
high-beam indicator
on
the
dash will come on.
Release
the lever to turn
the high-beam headlamps off.
2-35
Visor
Vanity Mirrors
Open the cover to expose the vanity mirror.
If
your vehicle has
the
optional lighted vanity mirrors,
the lamps come
on
when
you
open the cover.
Auxiliary
Power
Connection
Your vehicle is
equipped with an
auxiliary power
connection.
This
feature can be used to
add aftermarket
electrical equipment
to
your vehicle.
It
is
located
on
the passenger’s side
of
the vehicle,
below the
fuse panel. For information
on
accessing the
connection and electrical hookup, please refer to your
service manual.
1
NOTICE:
Adding
some
electrical
equipment
to your
vehicle
can
damage
it or keep
other
things
from
working
as they
should.
This
wouldn’t
be
covered
by
your
warranty.
Check
with
your
dealer
before
adding
electrical
equipment
and
never
use
anything
that
exceeds
the fuse rating.
2-51
Have
you
recently changed brands
of
fuel?
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
Warning
Light
If
you have a problem with
your oil, this light may stay
on
after
you
start your
engine,
or come on when
you are
driving.
This indicates that oil
is not going through your engine
quickly enough
to
keep it lubricated. The engine
could
be low on oil or could have some
other oil problem.
Have it fixed right away.
The oil light could also come on in the
following situations:
The
light will come
on
briefly when you turn on the
ignition to show
you
that it is working properly. (If it
doesn’t come
on
with the ignition on, you
may have
a problem with the
fuse
or bulb. Have it
fixed
right away.)
Sometimes when the engine is idling at
a
stop, the
light may blink on and off.
This
is normal.
Electrical
System
Add-on Electrical
Equipment
NOTICE:
Don’t
add
anything
electrical
to
your
Buick
unless
you
check
with
your
dealer
first.
Some
electrical
equipment
can
damage
your
vehicle
and
the
damage
wouldn’t
be covered
by
your
warranty.
Someadd-on electrical
equipment
can
keep
other
components
from
working
as
they
should.
Your vehicle has an air bag system. Before attempting
to
add anything electrical to your Buick, see “Servicing
Your Air Bag-Equipped Buick” in the Index.
Headlamp
Wiring
The headlamp wiring is protected by a
circuit breaker in
the underhood electrical center.
An
electrical overload
will cause the lamps to go on and off, or in some cases
to remain
off.
If
this happens, have your headlamp
system checked right away.
Windshield
Wipers
The windshield wiper motor is protected
by
a circuit
breaker and a fuse.
If
the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power
Windows
and
Other
Power
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load
is
too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
6-56
Fuses
and
Circuit
Breakers
The wiring circuits
in
your vehicle
are protected from
short circuits by a combination of fuses,
circuit
breakers
and fusible
thermal links
in
the wiring itself. This
greatly reduces the chance of fires 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.
