airbag CHEVROLET EXPRESS 2007 Workshop Manual

The vehicle has an airbag system. Before attempting
to add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 2-78andAdding
Equipment to Your Airbag-Equipped Vehicle on
page 2-79.
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 the 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.

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.
