SAFETY PRECAUTIONS

STOP! CAREFULLY READ THE IMPORTANT SAFETY PRECAUTIONS AND WARNINGS BEFORE PROCEEDING WITH THE INSTALLATION!

Appropriate disassembly, assembly methods and procedures are essential to ensure the personal safety of the individual performing the kit installation. Improper installation due to the failure to correctly follow these instructions could cause personal injury or death. Read each step of the installation manual carefully before starting the installation.

  • Always wear safety glasses for eye protection.
  • Place the ignition switch in the OFF position.
  • Always apply the parking brake when working on the vehicle.
  • Block the front and rear tire surfaces to prevent unexpected vehicle movement.
  • Operate the engine only in well-ventilated areas to avoid exposure to carbon monoxide.
  • Keep yourself and your clothing away from moving parts when the engine is running.
  • Do not wear loose clothing or jewelry that can be caught in rotating or moving parts.
  • Allow the engine, cooling system, brakes and exhaust to cool before working on a vehicle.
  • Do not smoke or use flammable items near or around the fuel system.
  • Use chemicals and cleaners only in well-ventilated areas.
  • Batteries can produce explosive hydrogen gas which can cause personal injury. Do not allow flames, sparks or flammable sources to come near the battery.
  • Keep hands and any other objects away from the radiator fan blades.

  8. Center Valance Installation
    1. Apply adhesion promoter to the rear fascia in a 1/2in strip just below the previously marked grease pencil lines. This is the area where the Center Valance double-sided tape will interface the rear fascia (Refer to Figures P a. and b.).
    2. Install center valance to rear fascia by removing tape backing just enough to make a tab to pull once part is correctly situated on vehicle (Refer Figure Q).
    3. Once the part is aligned to previously marked grease pencil lines, pull the tape backing off using the tabs and press firmly to ensure good adhesion (Refer Figure R).
    4. Reach into the loosened fascia and install M4.2 x 18-mm screws into center valance (4 total). Do not over tighten screws or warping of the fascia will occur.

    2. With fascia seated properly to rear of vehicle, reengage fascia sides into body retaining clips.
    3. When the fascia is in place, replace the screws in the wheel wells (2 each side) and tighten the nuts from inside the trunk.
    4. Replace pushpin into the center fascia support found underneath the fascia. (Note- this is the only support remaining, the other two were removed for exhaust cutouts)

  11. Valance Brackets installation
    1. Install “L” brackets to the Center Valance.
      1. Fasten using pushpins, 2 each bracket (Refer to Figure T).
