2005 BUICK LACROSSE Fuses and circuit breakers

When trying to start the vehicle, if the engine does not
start and the STARTING DISABLED warning message
on the Driver Information Center (DIC) comes on,
the key may have a damaged transponder. Turn the
ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-88. If the engine still
does not start with the other key, the vehicle needs
service. If the vehicle does start, the rst key may be
faulty. See your dealer who can service the
PASS-Key
®III to have a new key made. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-6for more information.
It is possible for the PASS-Key
®III decoder to accept
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the programmed keys are lost or do not
operate, see your dealer or a locksmith who can service
PASS-Key
®III to have keys made and programmed
to the system.To program the new key do the following:
1. Verify that the new key has PK3 stamped on it.
2. Insert the master key in the ignition and start
the engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to RUN
within ve seconds of removing the original key.
5. The STARTING DISABLED warning message on
the DIC will turn off, once the key has been
programmed. It may not be apparent that the
STARTING DISABLED warning message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If the STARTING DISABLED warning message appears
and stays on the DIC while the vehicle is being
driven, the engine will be able to be restarted if it is
turned off. Your PASS-Key®III system, however, is not
working properly and must be serviced by your
dealer. The vehicle is not protected by the
PASS-Key
®III system at this time.
If the PASS-Key
®III key is lost or stolen, see your
dealer or a locksmith who can service PASS-Key®III to
have a new key made.

Turn and Lane-Change Signals
To signal a turn, move the lever up or down. The lever
returns to its original position when the turn is completed.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the lever until
the arrow starts to ash. Hold it there until the lane
change is completed. The lever will return to its original
position when released.
Arrows that ash rapidly when signaling for a turn or lane
change, or that fail to work, may indicate a burned-out
signal bulb or fuse. Other drivers will not see the signal.
SeeFront Turn Signal and Parking Lamps on page 5-47
andTaillamps, Turn Signal, Sidemarker, Stoplamps and
Back-up Lamps on page 5-48for turn signal bulb
replacement procedures. Also seeFuses and Circuit
Breakers on page 5-88for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever away from you.
When the high beams are
on, a light on the
instrument panel cluster
also will be on if the
ignition is in ON.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward you.
Flash-to-Pass
This feature lets you use your high-beam headlamps
momentarily to signal a driver in front of you that
you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.

Power Windows and Other
Power Options
Circuit breakers in the instrument panel fuse block
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 xed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse block wiring itself. This greatly reduces
the chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Make sure a
bad fuse is replaced with a new one of the identical
size and rating.
Instrument Panel Fuse Block
The instrument panel fuse
block is located on the
passenger’s side of
the instrument panel. Pull
off the cover labeled
FUSES to expose the
fuse block.
