Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage
your vehicle and the damage would not be covered
by your warranty. Some add-on electrical equipment
can keep other components from working as they
should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-70.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
Power Windows and Other Power
Options
Circuit breakers in the 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 or
goes away.

Vehicle Data 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
This data can help provide a better understanding of the
circumstances in which crashes and injuries occur.Important:EDR data is recorded by your vehicle
only if a non-trivial crash situation occurs; no data is
recorded by the EDR under normal driving conditions
and no personal data (e.g., name, gender, age, and
crash location) is recorded. However, other parties,
such as law enforcement, could combine the EDR data
with the type of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR
is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have the
special equipment, can read the information if they have
access to the vehicle or the EDR.
GM will not access this data or share it with others
except: with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee; in
response to an official request of police or similar
government office; as part of GM’s defense of litigation
through the discovery process; or, as required by law.
Data that GM collects or receives may also be used for
GM research needs or may be made available to others
for research purposes, where a need is shown and the
data is not tied to a specic vehicle or vehicle owner.
