BUICK LESABRE 2001 Owner's Manual

6-61
Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears
on a plate in the front corner of the instrument panel,
on the driver's side. You can see it if you look through
the windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You'll find this label on your spare tire cover. It's very
helpful if you ever need to order parts. On this label is:

your VIN,

the model designation,

paint information and

a list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-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 vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Power Windows and Other
Power Accessories
Circuit breakers in the rear electrical center 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.
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 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.
You will find a fuse puller clipped in both of the bussed
electrical centers. Snap the wide end of the fuse puller at
the side indentations and pull the fuse out.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine compartment
on the passenger's side and the other under the rear seat
on the driver's side. If a MaxiFuse should blow, have
your vehicle serviced by your dealer immediately.

6-63
Engine Compartment Bussed Electrical
Center (BEC)
The front Bussed Electrical
Center (BEC) is located in
the front of the engine
compartment on the
passenger's side. Lift the
cover to gain access.
See ªEngine Compartment
Overviewº in the Index
for more information
on location.
On some vehicles, there may be an additional cover
that you will need to lift to gain access to the fuses.
Fuse 22 or 23 can be moved to the outer position
to provide continuous power to the auxiliary outlet
or cigarette lighter when the ignition is not ON.
See your dealer for additional assistance, if needed.

53 Fuse PullerRemoving the Rear Seat Cushion
NOTICE:
The battery and main fuse blocks are located
under the rear seat cushion. The battery's
ground terminal and some relay wires are
exposed. To help avoid damage to the battery
and wires, be careful when removing or
reinstalling the seat cushion. Do not remove
covers from covered parts. Do not store anything
under the seat, as objects could touch exposed
wires and cause a short.
To remove the rear seat cushion:
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front of
the vehicle.

6-66
To reinstall the rear seat cushion:
CAUTION:
A safety belt that isn't properly routed through
the seat cushion or is twisted won't provide the
protection needed in a crash. If the safety belt
hasn't been routed through the seat cushion
at all, it won't be there to work for the next
passenger. The person sitting in that position
could be badly injured. After reinstalling the seat
cushion, always check to be sure that the safety
belts are properly routed and are not twisted.
1. Buckle the center passenger position safety belt, then
route the safety belts through the proper slots in the
seat cushion. Don't let the safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear
-locating guides hook into
the wire loops on the back frame.
3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly routed
and that no portion of any safety belt is trapped under
the seat. Also make sure the seat cushion is secured.

Rear Underseat Bussed Electrical Center (BEC)
The rear BEC is located
beneath the rear seat on the
driver's side. The rear seat
cushion must be removed to
access the BEC. See
