Airbag System
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’s 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” — such as improperly mounted
equipment — can greatly affect the performance
of the airbag.
{CAUTION:
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 1-6
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: Yes, particularly if the push bumper significantly
changes the front structure of the vehicle. However,
GM conducts analysis on various push bumper
configurations to verify effectiveness of the sensing
performance system with minor changes in the
front structure of the vehicle which may occur from
the addition of a push bumper.
1-3

Q: Is there anything I might add to the exterior 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’s manual. See “Customer Satisfaction
Procedure” in your owner’s manual index.
If your vehicle has rollover roof-rail airbags, see
“Different Size Tires and Wheels” in your owner’s
manual for additional important information.
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 your owner’s manual.

Notices for Customer-Installed
Equipment
Read the following notices before installing equipment
on your specialty vehicle.
Notice: GM-approved service procedures must be
followed to remove and reinstall the instrument
panel to the pad in order to ensure proper airbag
deployment.
Notice: Do not mount equipment on the passenger
side of the instrument panel top pad deployment
zone. Equipment should not be mounted on or
around the passenger airbag opening because of a
deploying airbag. To allow the airbag to perform
as it was designed, do not mount equipment inside
the airbag deployment zone.
Notice: Your police vehicle may have optional
roof-rail airbags. Do not mount a security barrier
such that the ends of the barrier or brackets
are within the roof-rail deployment zones.
Notice: Your police vehicle may have roof-rail
airbags and a rollover sensor. The rollover sensor is
mounted on the centerline of the vehicle between
the driver and right front passenger positions.
If your vehicle has bucket seats, the rollover sensor
will be exposed. Do not mount equipment within
25 mm (1 in) of the rollover sensor. This may impact
the performance of the airbag system. To allow
the airbags to perform as they are designed, do not
mount equipment near this area.
Notice: Avoid installing wiring for roof-rail
emergency lighting or radio antennas that may
restrict the proper deployment of the roof-rail
airbags.
