• Inadequate air conditioning performance unless system capacity is enough to cool the interior space of the completed vehicle.
Due to the critical nature of the accelerator system, anyone making modifications or alterations assumes complete responsibility for
system reliability, performance and compliance to FMVSS 124. Caution must be exercised so that the accelerator cable routing is
unchanged.
• Do not use accelerator cable or clips to route wires, harnesses or other cables. Cable sheath must be clipped so as not to pinch
inner cable. Cable must not be loose in clip allowing sheath to move when accelerator pedal is applied and released.
• Cable must not be subjected to kinking or routing across any sharp edges.
• Cable routing must be perpendicular to the surface of the front-of-dash at the dash fitting. No objects or routings should force
cable to have a bend at the dash fitting. Flexible components (hoses, wires, conduits, etc.) must not be routed within 2.0 in. (50
mm) of moving parts or accelerator linkage unless routing is positively controlled.
• Caution must be taken so that the accelerator pedal mounting and location remains unchanged. Guidelines for accelerator
pedal locations are as follows:
a. Ensure that the accelerator can freely operate from idle to wide-open throttle position and return. Make sure that the pedal
will not hang up on any nearby items such as carpets, floor, screws, wiring harnesses, etc. Engine cover should have at
least one inch (25 mm) clearance to side of accelerator pedal with the carpet mat installed.
b. Accelerator to brake pedal relationship has been designed to provide minimum driver movement and should not be
altered in any way.
The gasoline engine induction and/or ignition system is certified in compliance with the Federal Vehicle Emission Standards. Any
alterations to the systems or components could void compliance and render the vehicle illegal. Systems include:
• Fuel system - Port Fuel Injection and associated tubes, hoses and pipes, air cleaner, outside air hose and spacer heat stove
and heat stove pipe, fuel pump and inlet manifold, fuel vapor canister.
• Exhaust system.
• Ignition system distributor and initial spark timing setting, spark plugs and spark plug wires.
• Crankcase ventilation system.
The diesel engine induction and injector pump system is certified to be in compliance with the Federal Vehicle Emission
Standards and/or Noise Standards. Any alterations to the system or components could void compliance and render the vehicle illegal.
