Si-Drive (Subaru Intelligent Drive) - Subaru 2007 B-9 Tribeca Technicians Reference Booklet

2007 New Model Update

SI-DRIVE (SUBARU INTELLIGENT DRIVE)

SI-DRIVE (Subaru Intelligent Drive) will be standard on all Legacy and Outback turbo models. SI-
Drive enables three distinctively different modes of engine power characteristics by regulating the
engine control unit (ECM) as well as the transmission control unit (TCU) on automatic transmission
models, and by fine-tuning the electronically controlled throttle Torque command control with 3
settings (rotary switch is located in the center console). No other parts are required.
This graph shows the relationship of accelerator pedal movement to throttle response in each of
the SI Drive modes. In each case the accelerator pedal is depressed 100%.
I mode: Throttle response provides efficient performance.
S mode: Throttle response is almost linear.
S# mode: Throttle response is fast, reaching 100% with approximately 54% of
accelerator pedal movement.
