7-8. SI-DRIVE (If Equipped)
SI-DRIVE (SUBARU Intelligent Drive)
works to maximize engine performance,
control and efficiency.
This system consists of two modes:
Intelligent (I) and Sport Sharp (S#). By
operating the SI-DRIVE switches, the
character of the power unit changes.
& Intelligent (I) Mode
! For smooth, efficient performance
driving
The linear acceleration characteristic of
the Intelligent (I) mode is ideal for normal
driving usage.
The Intelligent (I) mode provides well-
balanced performance with greater fuel
efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency.
This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttle
response.
& Sport Sharp (S#) Mode
! For maximum performance driving
For sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
SI-DRIVE
ideal for tackling twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence.
& SI-DRIVE Switches
. To select the Intelligent (I) mode, press
the "I" switch.
. To select the Sport Sharp (S#) mode,

NOTE
. While the engine is cool, you cannot
change to Sport Sharp (S#) mode.
. The next time you turn on the engine,
after you turned off the engine in the
Sport Sharp (S#) mode, the SI-DRIVE
mode changes to the Intelligent (I)
mode.
