BODY BUILDERS INSTRUCTIONS

The Incomplete Vehicle Document (IVD) is supplied with each incomplete vehicle, and provides information that should be used by
intermediate and final stage manufacturers in determining conformity to applicable Federal Motor Vehicle Safety Standards (FMVSS). The
IVD also includes information which must be followed in order to ensure that Environmental Protection Agency (EPA) and California emissions
certification requirements and NHTSA Fuel Regulations are met.
The Body Builders Book contains information that may be used in addition to the IVD for any manufacturer making alterations to a GM
complete/incomplete vehicle. No alteration should be made to the incomplete vehicle which either directly or indirectly results in any
component, assembly or system being in nonconformance with any applicable Federal Motor Vehicle Safety Standard or Emission
Regulation. Intermediate and final stage manufacturers should be familiar with all Federal Motor Vehicle Safety Standards and Emission
Regulations and aware of their specific responsibilities as manufacturers.
It is the responsibility of the final stage manufacturer, vehicle modifier or alterer to insure compliance of the completed, modified or altered
vehicle to all applicable Federal Motor Vehicle Safety Standards and regulations.
General Motors vehicles may contain systems that provide coverage beyond Federal Motor Vehicle Safety Standards and regulations. It is the
responsibility of the vehicle final stage manufacturer, modifier or alterer to ensure these systems operate appropriately once the vehicle has
been completed, modified or altered.

Section 0 — General Instructions
Check for proper clearance between body members and chassis components, which may in any way affect the reliability and performance
of the vehicle by developing abrasion and wear points from moving parts or degradation from extreme environment or thermal exposure or
may increase interior noise. Any attachments must consider chassis components for jounce and rebound motion at maximum GVW.
Check headlamp aim and all vehicle illumination systems for proper operation when the vehicle has been completed. Re-aim headlamps
when necessary. Check for proper operation of windshield washer, wipers and defroster system. In no case should any alterations affect the
function, physical or mechanical properties, environment or vital spatial clearances of the components, assemblies or systems.
Extreme care must be taken when working on vehicles which have been equipped with Powertrain Control Module (PCM), Sensing and
Diagnostic Module (SDM) (Air Bag Control Module) and ABS Control.
Do not mount any components with large magnets, such as stereo speakers, in the area of the driver's seat due to the Sensing and
Diagnostic Module (SDM).
The frontal airbag sensor, on the lower radiator support cannot, under any circumstance, be moved from the present mounting location.
The SDM, side impact sensor (SIS), and rollover sensor (ROS) cannot, under any circumstance, be moved from their present mounting
locations in vehicles equipped with head-curtain side-impact air bags. Optional: The SDM may be relocated in incomplete vehicles with
the VXT and Y3H options.
