NOTICE:
1. Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.
2. Insert the gear of the heater control housing sub-assembly perpendicular to the No. 1 center cluster module circuit sub-assembly.
3. The metal cover of the encoder can easily come off, so hold the cover in place while inserting the gear.
4. Do not place excessive force on the dials of the heater control housing sub-assembly.
5. Do not allow oil, grease or other foreign matter to contact the heater control housing sub-assembly and prevent it from being damaged.
6. After installing the heater control housing sub-assembly with the screws, remove the tape fixing the dials in place from the new heater control housing sub-assembly.

  HINT:
  Position the control knob sub-assembly so that the knobs face upwards and, while holding the front air conditioning panel sub-assembly parallel to the control knob sub-assembly, place the front air conditioning panel sub-assembly onto the control knob sub-assembly to install it.
  NOTICE:
  1. Be sure not to allow skin oils, grease, foreign matter, etc. to adhere to the parts and be sure not to damage the parts.
  2. When installing the control knob sub-assembly and No. 1 center cluster module circuit sub-assembly to the front air conditioning panel sub-assembly, make sure that the ribs are properly engaged as shown in the illustration.
  3. Do not apply excessive force to the knobs when installing the control knob sub-assembly as the knobs break easily.
  4. Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.
2. Install the 6 screws.
