OCCUPANT RESTRAINTS
Driver and Passenger Advanced Front Air Bags, Supple-
mental Side Curtain Air Bags (SABIC), and Seat-Mounted
Side Air Bags (SAB) affect the way special service equip-
ment can be safely mounted in special service vehicles.
Any surface that could come into contact with an air bag,
once it has been deployed, must not damage the air bag or
alter its deployment path.
The addition of the supplemental equipment (such as
radios, weapons, mounting brackets, cage, etc.), must be
installed such that it will not interfere or come in contact
with a deploying air bag. Air bag deployment zones are
described below. Sharp edges, corners or protrusions on
supplemental equipment, could damage the nylon air bag
material and reduce the effectiveness of the air bag during
a deployment.
WARNING!
•Vehicles equipped with left and right Supplemental
Side Curtain Air Bags (SABIC) must use police cages,
which have been approved by the equipment manu-
facturer, for use in the vehicle.
(Continued)
WARNING! (Continued)
•The area where the Supplemental Side Curtain Air
Bags (SABIC) is located should remain free from any
obstructions.
• If your vehicle is equipped with left and right
Supplemental Side Curtain Air Bags (SABIC), care
must be taken when installing any type of roof
equipment. Drilling and installation of fasteners or
other equipment that may interfere with the Supple-
mental Side Curtain Air Bags (SABIC) and air bag
wiring harness is not permitted. Furthermore, make
sure no equipment or fasteners are located in the air
bag deployment zone.
• Do not place objects or mount equipment in front of
the air bag module cover, or in front of the seat areas
that may come in contact with a deploying air bag.
• Dash, tunnel or console mounted equipment should
not be placed outside of the specified zone.
• Failure to follow these instructions could result in
personal injury.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 7

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENTSpecial design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
