Electrical System
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle’s battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-58.
Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers 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
or goes away.
Power and Heated Seat
Circuit Breakers
There is a circuit breaker located
underneath the driver’s side
front seat that controls the power
and heated seat functions.
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 res 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 do not 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.

Recording and
Privacy
Your GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven. For
example, your vehicle uses computer
modules to monitor and control
engine and transmission
performance, to monitor the
conditions for airbag deployment and
deploy airbags in a crash and, if so
equipped, to provide antilock braking
to help the driver control the vehicle.
These modules may store data to
help your dealer/retailer technician
service your vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio pre-sets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle has an Event
Data Recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-like
situations, such as an airbag
deployment or hitting a road
obstacle, data that will assist in
understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
How various systems in your
vehicle were operating
Whether or not the driver and
passenger safety belts were
buckled/fastened
How far, if at all, the driver was
pressing the accelerator and/or
brake pedal
How fast the vehicle was
traveling
