2000 PONTIAC BONNEVILLE headlamp

6-50
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.Used Replacement Wheels
CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used or
how far it's been driven. It could fail suddenly
and cause an accident. If you have to replace a
wheel, use a new GM original equipment wheel.
Tire Chains
NOTICE:
If your vehicle has P235/55R17 size tires, don't
use tire chains. They can damage your vehicle
because there's not enough clearance.
NOTICE: (Continued)

6-61 Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker. 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 an internal
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, be sure to have it fixed.
Power Windows and Other Power Options
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 damage
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.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. 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 the correct amperage.
Replace it as soon as you can.
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.
Removing Fuses
You will find a fuse puller attached in both of the BEC.
Snap the wide end of the fuse puller on to the fuse, at
the side indentations holding the puller and pull the
fuse out.

6-62 Engine Compartment Bussed Electrical
Center (BEC)
As mentioned above, the
front BEC is located in
the front of the engine
compartment on the
passenger's side. Lift the
cover to gain access.
Fuse 22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance, if needed.
