Electrical System
Add-on Electrical Equipment
I 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. 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 Buick, see “Servicing
Your Air Bag-Equipped Buick” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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.
Engine A/C, EGR, Relays, SIR Crank and
Safety Belt Fuses
These fuses are located behind the glove box. The fuse
holders are taped together with gray tape.
Other - uses
The Safety Belt/Chime (ICAM) Module fuse and the
Remote Keyless Entry fuse are located behind the fuse
block, above the hush panel.
The Fuel Pump, A/C CONT and the ECM fuses are
located under the hood.

At Least Twice a Year
Restraint System Check
Make sure the safety belt warning light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for
any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
“Automatic Transaxle” in the Index. A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication Service

hinges and latches, including those for the hood,
rear compartment, glove box door, and any folding
seat hardware. Part
D tells you what to use. More
frequent lubrication may be required when exposed to
a corrosive environment.

A CAUTION:
When you are doing this check, the vehicle could
move suddenly. If it does, you or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake (see “Parking
Brake’’ in the Index if necessary)
and the
regular brake.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK
(P) or NEUTRAL (N). If
the starter works in any other position, your vehicle
needs service.
Brake-Transaxle Shift Interlock (BTSI) Check
A CAUTION:
When you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake, try to move the shift lever out
of
PARK (P) with normal effort. If the shift lever
moves out
of PARK (P), your vehicle’s BTSI
needs service.
