When

PASS-Key%
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
goto the engine.
If
someone
tries
tostart 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 engine

light may
remain
on
during
this
time.
If the starter still won’t
work,
and
the

to be
clean
and
dry,
wait
about
three minutes and
try
another
ignition
key.
At
this
time,
you
may

want
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%.

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.
There
are
two
fuse
blocks
in your
vehicle.
One
is at
the
end of the
instrumept
panel
on
the
driver’s
side.
The cover
will
pull
right
off,
To put
the
cover
back
on
make
sure
the
tabs
are
inserted
first.
The other
ia
in
the
engine compamgnt. Open
the
cover
on
either of the
boxes
to
expose
the
fuses.
Look
at
the
silver-colored
band
inside
the
fuse.
If
the
ba
is
broken
or
melted,
replace
the
fuse.
Be sure you replace
a
bad fuse
..
-
with
.
a
new
one
of the
correct
size
and
rating.
Be
sure
to
use
the correct fuse if
you
need
to
replace
one.
If
you ever
have
a
problem
on
the road
and
don’t
have
a
spare
fuse,
you
can
“borro~”
one of the
exactly
the same
value. Just pick
some
feature of your
vehicle
that
you
can
get
along
without
--
like the
radio
or
cigarette
lighter
--
and
use its fuse, if it is of
the
value
you
need.
Replace
it
as
soon
as
you
can.
Headlamps
The headlamp
wiring
is-protectedby
a
circuit
breaker
in
the lamp
switch.
An
electrical
overload
will
cause
the
lamps
togo on
and
off,
or in some cases to
remain
off.
If
this
happens,
have
your
headlamp
wiring
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
eools. If
the overload
is
caused
by
some
electrical problem
and
not
snow,
etc.,
be
sure to get it fixed.
Power Winbws and
Other
Power
Options
Circuit bfialters 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
or
goes
away.
Lumbar
Power
Seat
Controls
If
you
havethe lumbar
controls for the
power
seat,
there
is a fuse under
each
seat
wrapped
in tape.
Should
your
seat
not
work,
this
fuse should
be
checked.
