      Note


      • Replace the clutch disc and clutch cover together. If only one is replaced, the adjustment system of the clutch cover does not function properly. This may cause clutch drag or clutch slippage, which may result in deterioration of drivability or malfunctions of the system parts.

      • After replacing any system components, perform initialization and learning of related components (refer to the operations listed above). If initialization and learning are not performed, the transmission system will not function properly.

      • Before proceeding with learning of the multi-mode manual transmission system, clear the previously stored learning values. Since the multi-mode manual transmission system does not have an overwrite function, clearing stored data is necessary to learn the system.

  5. PRECAUTIONS REGARDING USE OF SHIFT LOCK RELEASE BUTTON


    1. When the vehicle is parked with the shift lever in any position other than N:


      • When the shift lock is released by operating the shift lock release button, the engine cannot be started even if the shift lever is in N position, because the gear is not in neutral.

      • Return the shift lever to the position it was in when the vehicle was parked, to resynchronize the gear position and shift lever position, and then move the shift lever to the N position. It will then be possible to start the engine.

    2. When the vehicle is parked with the shift lever in the N position:


      • When the shift lock is released by operating the shift lock release button, the engine cannot be started even if the gear is in neutral, because the shift lever is not in N position.

      • If the gear position and shift lever position do not match, the multi-mode manual transmission system does not operate.

      • The multi-mode manual transmission system operates after the gear position and shift lever position are matched by moving the shift lever back to the N position.

    3. If the shift lever position is moved using the shift lock release button because of repairs, inspections and so on, perform following procedure to start the engine.


      1. Turn the ignition switch to ON.

      2. Depress the brake pedal.

      3. Move the shift lever back to the position it was in when the vehicle was parked.

      4. Confirm that the gear position and shift lever position match. If the gear position and shift lever position do not match, the gear position indicator light (built into the combination meter) blinks.

      5. Move the shift lever to the N position.

      6. Turn the ignition switch to the ST position: cranking the engine.

  6. OTHER PRECAUTIONS REGARDING MULTI-MODE MANUAL TRANSMISSION SYSTEM


    • Set the gear in neutral when racing the engine.

    • Set the gear to the neutral position before removing the shift and select actuator. If the gear cannot be shifted to the neutral position due to malfunctions of the actuator and/or transaxle gear, remove the plug from the shift and select actuator and observe the position of the shift slit within. If the slit is in a position other than neutral, use a screwdriver to set it to neutral.

  8. PRECAUTION REGARDING USE OF INTELLIGENT TESTER

    Note


      Observe the following items for safety reasons:

    • Read its instruction books before using the tester.

    • Prevent the tester cable from being caught on the pedals, shift lever and steering wheel when driving with the tester connected to the vehicle.

    • When driving the vehicle for testing purposes using the tester, two people are required. One drives the vehicle, and the other operates the tester.
