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.

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:
The police vehicle has
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: The police vehicle has
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 the 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
affect 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.

Notice:GM cannot be
responsible for any changes
made to the vehicle. Have all
electrical and body modifications
performed by experienced
technicians.
.Be sure that any modified or
added wiring will work
properly with your vehicle's
wiring system.
.See that all wiring is properly
protected by fuses, and not
causing an overload to
connectors and components.
.Do not route wiring in
areas of the vehicle where
temperatures can be high or
where wiring may be cut,
pinched or rubbed.
.See that all added wiring is
of the same or smaller gauge
than the wire it is being
attached to for proper fuse
protection.
.Be sure that all holes drilled
in the body are properly
sealed and corrosion
protected. See that the
vehicle's wiring harnesses,
piping and other components
have not been displaced or

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
–12‐Volt
Accessory Power Supply
1. Disconnect the negative (−)
battery cable at the battery. The
negative (−) battery cable must
be disconnected before the
positive wiring lead is connected
to the power accessory.
2. Locate the power supply harnesses, one under the
instrument panel near the center
of the vehicle, and one within the
driver side rear cargo area jack
stowage compartment. 3. Prepare the wires that are to be
used to connect the power
accessory. Do not remove the
unused wires. Tape unused
wires back in their original
position under the instrument
panel.
4. Complete the wiring installation of the customer added
accessory with additional wire
required for the specific
electrical accessory power
connection. The wire gauge,
3.0 mm² (12 gauge), should be
the same as the wiring of the
installed harness.
5. The ignition must be turned to OFF prior to attaching the cables
to the battery, or serious damage
to the Body Control Module
(BCM) may result.
The windshield wiper switch and
the radio must be turned off
before attaching cables to the
battery.

50 amp circuit breaker with a GM
Part No. 15319848 circuit breaker,
or equivalent.
Reinstall the storage tray into the
compartment by lifting it into the
instrument panel.
Auxiliary Battery Power
Junction Blocks
Two auxiliary power junction blocks
are located within the driver side
rear cargo area jack stowage
compartment. Each junction block is
powered directly from the battery
through a 50 amp circuit breaker for
connection to customer‐furnished
equipment. The two circuit breakers
are located in the breaker/relay
panel forward of the instrument
panel glove box. A maximum load of
50 amps (600 watts) can be
connected to each junction block.
The wiring diagram for this circuit is
shown as part of the diagram for
“Wiring Provisions–12 Volt Battery
Power”. The two junction blocks are
connected to coiled 1.5 m (5 ft)
branches of the rear body harness
and fastened near the jack.
Mounting of the junction blocks can
be at customer‐selected rear cargo
area locations permitted by the
branch harness length and using
customer‐furnished mounting
hardware.
The junction blocks should not be
attached to the interior trim plastic
components without appropriate
backing hardware to the mounting
bolts.
To connect the customer-furnished
equipment at the junction blocks,
use the following steps:
1. Disconnect the negative (−)
battery cable.
2. Connect the customer-furnished equipment positive leads to the
junction block terminals and
tighten to 15 N·m (11 lb ft).
The ignition must be turned off
and the vehicle vacated prior to
connecting the negative (−)
battery cable to the battery.
3. Reconnect the negative (−) battery cable to the battery.
Torque the bolt to 5 Y
(3.6 lb ft).
4. Set the time on the clock and radio pushbuttons as needed.
