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 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. The
SECURITY light will then come on. But you don’t have
to wait three minutes before trying another ignition key.
See your 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 dealer. Your
vehicle is not protected by the PASS-Key
I1
system.
If you lose or damage a PASS-Key I1 ignition key, see
your dealer or a locksmith who can service PASS-Key I1
to have a new
key made. In
an emergency, call the Buick
Premium Roadside Assistance Center at
1-800-252- 11 12. In Canada, call 1-800-268-6800.
Turn Signal
and
Lane
Change
Indicator
The
turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or
a
lane
change.
To
signal a turn, move the lever all the way
up or down.
When the turn
is finished, the lever will return
automatically.
5
I
An arrow
on
the instrument
panel will flash in
the
direction
of
the turn or
lane change.
1
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.
If
the arrow flashes faster than normal as
you
signal a
turn or
a lane change, 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 HigWLow
Beam Changer
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, this
light on the instrument
panel also will
be
on.
Sun
Visors
To block out
glare, you can swing down the visors. You
can also
move them from side
to
side.
The
visors also
have extenders that you can pull out
for added coverage.
Visor
Vanity
Mlirrors
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
(Power
Drop)
Your vehicle is equipped
with an auxiliary
This
feature
provides power, ground and accessory
wires which can be
accessed
to
add aftermarket
electrical equipment to your vehicle. It
is located on the
passenger’s side of the vehicle, under the
glove box,
and is labeled with a wire
functionand fuse
rating. For
information
on
accessing
the
connection
and electrical
hookup, please
refer
to your service manual. To order
a
service manual, see
“Service
Publications, Ordering”
in
the Index.
I
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.
Astroroof
(If
Equipped)
Your vehicle may
be equipped with an express-open
astroroof.
It
includes a sliding
glass panel and a
one-piece sunshade. The control
switch works only
when the ignition or
RAP is on.
See “Retained
Accessory Power” in the Index.
The control switch
is
located overhead on the headliner.
2-49
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.
2-62
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.
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.

Block
Some
fusesare in a fuse
block on the passenger’s
side of the instrument panel.
Pull off the cover labeled
