Questions and Answers
About Airbags and
Specialty Law
Enforcement Vehicles
Q: Can equipment such as radar
devices, video cameras, and
radio trees be mounted in a
specialty vehicle equipped
with a right front passenger
frontal airbag?
A: Yes, but care must be taken to
properly mount the equipment
outside of the airbag
“deployment zone.”
Q: What is the airbag “deployment zone”?
A: The term “deployment zone”
describes the space an airbag
takes up when fully inflated.
Airbags need room to work
properly, and anything in the
“deployment zone” — suchas improperly mounted
equipment
—can greatly affect
the performance of the airbag.
{WARNING
Airbags inflate with great force,
faster than the blink of an eye. No
objects, such as shotguns, should
be placed over or near the airbag
covers. Equipment mounted too
close to an inflating airbag could
break and become a dangerous
projectile in a crash, causing
injury to the vehicle's occupants.
Also, an object too close to an
inflating airbag could prevent the
airbag from operating properly.
If this ever happens, the airbag
would not be able to protect
occupants the way it was
designed to. To help prevent
injury and to allow the airbag to
perform as it was designed, do
not mount equipment inside the
airbag deployment zone.

Q: How can I identify the airbag“deployment zone” in my
vehicle?
A: See Airbag Deployment
Diagrams on page 3‑4 for more
information. The diagrams
provide the approximate
dimensions of the “deployment
zones” for your specialty vehicle.
Before doing any service work,
including the installation of any
equipment, consult the
appropriate service manual.
Q: Is it possible to shield equipment so it does not
interfere with airbag
deployment?
A: While shielding may protect
certain equipment from being
damaged or dislodged, it may
also negatively affect how an
airbag inflates. Therefore, we
cannot recommend the
placement of any equipment in
the deployment zone, even
when shielding. Q: Can the installation of push
bumpers on the front end of
the vehicle affect the
deployment of the airbag?
A: It is not likely that installing push
bumpers will affect sensing for
the airbag as long as the vehicle
structure itself is not modified.
GM is not aware of any adverse
defects from the many push
bumpers that have been
installed on current model GM
police vehicles with airbags.
Q: Is there anything I might add to the front or sides of the
vehicle that could keep the
airbags from working
properly?
A: Yes. If you add things that
change your vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Also, the
airbag system may not work
properly if you relocate any of
the airbag sensors. If you have any questions
about this, you should contact
Customer Assistance before you
modify your vehicle. The phone
numbers and addresses for
Customer Assistance are in
Step Two of the Customer
Satisfaction Procedures in the
owner manual. See
“Customer
Satisfaction Procedure” in the
owner manual Index.
The service manual has information
about the location of the airbag
sensors, sensing and diagnostic
module, and airbag wiring. See
“Service Publications Ordering
Information” in the owner manual.

9-2 Driving and Operating
Adding Equipment to Your
Vehicle
Before adding accessories or
equipment to your police vehicle,
there are some things you need
to know:
.The police vehicle's maximum
capacity weight.
.The weight of your police
vehicle, including a full tank of
fuel but without a driver and
passengers.
.The weight of items you plan on
adding to your police vehicle,
like roof mounted light bar(s),
push bumpers, security
barrier(s), rear storage
organizer, highway flares, fire
extinguishers, weapons,
ammunition, radios, and video
equipment.
.The weight and number of
passengers you intend to carry
in your vehicle.
.The total weight of any
additional cargo you intend to
carry in your vehicle.
When planning your vehicle
equipment installation remember not
to exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) of the front
or rear axles. To keep the available
load weight less than the vehicle
capacity weight, you may need to
limit the number of passengers you
carry in your vehicle or change your
choice of additional equipment.
Center of Gravity (CG)
A vehicle's center of gravity is an
imaginary location inside the vehicle
and is a balance point for the
vehicle mass as it moves down the
road. The police vehicle's center of
gravity, before you add a load and
passengers, is approximately
midway between the center of the
axles, up from the ground to just
below the front window, and
between the driver and passenger. Equipment location and weight on
the vehicle's center of gravity is
important to keep in mind when
planning an installation. Heavy
equipment should be positioned as
low and as far forward in the rear
load compartment as possible. Try
to mount the equipment below the
bottom of the side windows. Refer
to the Loading Zone chart and
diagram to help with your
installation plan.
A procedure to make the necessary
measurements and formulas to
calculate the vehicle longitudinal,
lateral and vertical position of the
center of gravity can be found in the
GM Coachbuilders Manual.
Equipment required to conduct the
measurements for calculating the
center of gravity are:
.Weight scales of sufficient
capacity to measure the vehicle
weight at each wheel.

15-6 Special Equipment Options
The vehicle is equipped with wiring
provisions for a 12-volt battery
power supply. Refer to the following
information when adding electrical
accessories that will use the 12-volt
power supply feeds connected to
the vehicle's electrical system. The
wiring harness is located below the
instrument panel near the center of
the vehicle. The following
information describes the breaker
and relay location and provides a
wiring diagram to aid in connecting
customer equipment.
Electrical Connections
Notice:Before modifying or
adding any wiring, be sure that it
will work properly with your
vehicle's wiring system. Because
there are so many modifications
that can be made for many
different bodies and accessories,
GM cannot take responsibility
for any changes made. Such
changes may not be covered by
your GM Warranty. Have the work
done by an experienced electrical
technician. All wiring must be properly
protected by fuses, etc. and must
be routed properly so that it will
not be cut, pinched or rubbed by
other parts of the vehicle. Do not
route wiring in areas where it will
be very hot. Be sure not to
overload the vehicle's wiring,
connectors and components. All
added wire must be at least the
same size as the wire being
attached to for proper fuse
protection.
Installation Instructions
