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.

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).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle. 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.

might not change your weight
ratings. Ask your dealer to help you
load your vehicle the right way.
