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.
{ 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
(Continued)
2-2
WARNING: (Continued) 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 2‑6
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.
2-3
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.
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.
2-4
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 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.

Loading the Vehicle
Tahoe Police and Special Service
Package
The information in this section of the supplement is for those who intend to install additional equipment to the police vehicle after it has left the factory, and for those who will be driving and loading the vehicle with passengers and/or cargo.
Two labels on your vehicle show how much weight it was designed to carry, the Tire and Loading Information label and the Certification/Tire label. These labels are attached to your vehicle and give you the maximum load capacity, the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for your vehicle. See “Loading Your Vehicle” in your owner manual Index for additional loading information.
The following guidelines can help you with proper loading and load distribution when installing additional equipment on the Tahoe Police Package.
{ WARNING:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do, parts on the vehicle can break, and it can change the way the vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of the vehicle.
5-2
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.
5-3
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.
.
A post‐type hoist or other means to safely elevate the front of the vehicle to at least an angle of
20 degrees above horizontal.
See your GM dealer to get more information about this coachbuilder procedure.
Keeping the center of gravity midway between the axles is also important to provide proper braking performance.
About half the total vehicle weight on each axle is recommended.
Weigh your vehicle after the additional equipment has been installed to determine the actual weight of your vehicle. Weigh the vehicle with a full tank of fuel and without passengers. You may need to put a limit on how many people or other equipment you can carry inside your vehicle after the additional equipment has been installed.

Exterior Lamp Emergency Flashing
System - SEO 6J7
SEO 6J7 provides a high-beam headlamps flashing module, rear lamps flashing and control wire for a customer-furnished switch to turn the module on or off.
The flasher control wire is coiled under the center of the instrument panel. This control lead may be combined with the interior wiring leads for SEO 6J3 when that option is ordered with SEO 6J7.
The headlamps flashing module is located below the passenger side front headlamp and forward of the passenger side front wheel. The module is connected to an inline connector in the forward lamp harness.
The headlamps flashing module is activated by the application of 12 volts to a dark green/red wire coiled in the passenger side footwell. When activated, the driver and passenger side high-beam headlamps and the high-beam instrument panel cluster light will flash alternately at 2.4 flashes per second.
When the headlamps flashing module is turned on, the module sends a signal to the Body Control Module
(BCM). The BCM alternately flashes the stop lamps and backup lamps. Depressing the brake pedal will override the stop lamp flashing and placing the transmission in reverse will override the backup lamp flashing.
During daylight conditions, the Daytime Running
Lamps (DRL) are automatically turned off whenever the headlamps flasher module is activated. During nighttime conditions, the low-beam headlamps turn on automatically while the high-beam headlamps flash.
Turning on the high-beam headlamps manually with the turn signal/multifunction lever will override the flashing module and the high-beam headlamps will operate continuously.
15-2
Headlamps Flasher Module — SEO 6J7
A 20 amp fuse protects the flasher module circuit.
This fuse is located in the underhood fuse block in the engine compartment on the driver side of the vehicle and is labelled HEADLAMP WASH . See “Underhood
Fuse Block” in the Service and Appearance Care section of the Tahoe owner's manual for more information.
When it is dark outside, the taillamps will turn on automatically. The Center High-Mounted Stoplamp
(CHMSL) will not flash and will operate only when the regular brake pedal is pressed.

The 12‐volt battery power is supplied through two underhood mega fuses, one 125 amp and one 60 amp.
This underhood power is fed to the breaker/relay center via a harness that passes through the driver side front of the dash, and routes across the instrument panel to a position forward of the glove box. The breaker/relay center is mounted to the instrument panel structure forward of the glove box. The center includes a plastic bracket, two relays, two 30 amp breakers and three 50 amp mega circuit breakers.
Two 30 amp breakers supply power from the underhood
60 amp mega fuse through the contacts of the control relays to 12 gauge (3.0 mm²) blunt cut wires. These two blunt cut leads are part of wire coil under the instrument panel near the center of the vehicle.
Each relay is operated by a 20 gauge (0.5 mm²) blunt cut, light or dark blue control lead included in the 4 foot
(122 cm) loop of wire coiled under the instrument panel.
Three 50 amp mega circuit breakers, protected by three fusible links, supply power directly from the underhood 125 amp mega fuse through three, 10‐gauge wires (5.0 mm²) wires. Two of the wires are routed through the body harness to buss junction blocks in the left rear of the cargo area and secured near the jack and tools. This 4 foot (122 cm) of coiled wires can be accessed by removing the cup holder on the top of the trim panel. The third 10‐gauge (5 mm²) wire is a blunt cut lead which is part of the 4 foot (122 cm) loop of wire coiled under the instrument panel near the center of the vehicle.
