Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
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.
Your vehicle has an air bag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 96.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
engine compartment fuse block. An electrical
overload will cause the lamps to flicker on and off,
or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wiper Fuses
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. Although the circuit is
protected from electrical overload, overload due
to heavy snow, etc., may cause wiper linkage
damage. Always clear ice and heavy snow from
the windshield before using the windshield wipers.
If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
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.

(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine parts as needed. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap and cleaning the outside of the
radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 344 and Windshield
and Wiper Blades on page 387 for more
information.
(e)Make sure the safety belt reminder light and
all 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 airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.(f)Lubricate all key lock cylinders, hood hinges,
hood prop rod pivot, hood latch assembly,
secondary latch, pivots, spring anchor, release
pawl, rear compartment hinges, latches, locks, fuel
door hinge, and any moving seat hardware. More
frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease
on weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Vehicles with Gross Vehicle Weight Rating
(GVWR) above 10,000 lbs (4 536 kg) only: Inspect
shields for damage or looseness. Adjust or
replace as required. This is a Noise Emission
Control Service. Applicable to vehicles sold in the
United States and recommended for vehicles
sold in Canada.
(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
-In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
-In hilly or mountainous terrain.
-When doing frequent trailer towing.
-Uses such as found in taxi, police,
or delivery service.

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 anti-lock 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.
441

Event Data Recorders
Some information about your vehicle’s
performance and how it is driven may be recorded
on various modules if a crash occurs. Some
people refer to these modules asevent data
recorders (EDRs). These modules may record
several seconds of pre-crash and crash data,
such as data related toengine speed, brake
application, throttle position, vehicle speed,
yaw rate, steering wheel angle, lateral
acceleration, safety belt usage, airbag
readiness, airbag performanceandthe severity
of the collision.Unlike the flight data recorders
on airplanes, these modules do not record
sounds or conversations.To retrieve this data, special equipment and
access to the vehicle or the module that stores
the data are required. Certain data may also
be sent to or retrieved by OnStar®(see below).
GM will not access this information 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 specific vehicle
or vehicle owner.
Others may be able to retrieve this data if they
have access to the vehicle and have the special
equipment necessary to download the data.
