SFI SYSTEM


  1. FUNCTION


    1. When abnormal driver accelerator pedal and shift operations are detected, the system limits the engine output and informs the driver.

      Tech Tips

      When the system is operating, even if the driver depresses and holds the accelerator pedal, engine output may increase on an uphill slope and decrease on a downhill slope. This behavior allows the system to restrict the vehicle speed and acceleration below the predetermined limit on slopes and is not a malfunction.

    2. Control during Reverse Operation


      1. Responds to excessive depression of the accelerator pedal while operating in reverse.

      2. Corrects engine output according to the road grade and steering angle.

        Control Start Conditions (When all of the following conditions are met, control starts.)
        • Shift position is R.

        • Accelerator pedal is depressed.

        Control Operation Limits the engine output so the vehicle speed and acceleration are at or below a certain level.
        Control Stop Conditions
        • Shift position is not R.

        • Accelerator pedal is fully released.

    3. Control during Manual Shift Operation


      1. Responds to shift operations with the accelerator pedal depressed.

      2. Changes the limit amount according to the manual shift operation pattern.

      3. Corrects engine output according to the road grade and steering angle.


        1. Control when Starting Off from a Parked Position

          Control Start Conditions (When all of the following conditions are met, control starts.)
          • Shift position is changed from P to D, or P to R.

          • Accelerator pedal is depressed.

          Control Operation Limits the engine output so the vehicle speed and acceleration are at or below a certain level.
          Control Stop Conditions
          • Shift position is P or N.

          • Accelerator pedal is fully released.

        2. Control when Starting Off from a Parked Position

          Control Start Conditions (When all of the following conditions are met, control starts.)
          • Shift position is changed from R to D, D to R, or N to R.

          • Accelerator pedal is depressed.

          Control Operation Limits the engine output so the vehicle speed and acceleration are at or below a certain level.
          Control Stop Conditions
          • Shift position is P or N.

          • Accelerator pedal is fully released.

          Tech Tips


          • The engine output restraint level differs in the above 2 situations.

          • During control while a manual shift operation is performed (from control start until the accelerator pedal is released), the system informs the driver of the control via the multi-information display. For details, refer to the combination meter assembly.
