Front Hood and Hood Scoop
Due to the lightweight material, a
slight vibration is normal at higher
speeds and will not affect the
durability of the hood. To avoid
deforming the front hood when
closing, do not press down on the
hood with your hands. You can
release your hold on the front hood
approximately 12 inches above
the closing position and its weight
should cause it to close securely.
Limited Slip Rear Differential (WRX STI only)
The Limited Slip Rear Differential provides optimum distribution of power according to the
difference in revolution between the right and left rear wheels that may be caused by certain
driving conditions, thereby improving driving stability on snow-covered, muddy or other
slippery roads or during high-speed driving. Due to the nature of this mechanical Limited
Slip Rear Differential, the differential gears may emit a vibration and/or noise when making
turns. When servicing, use only specified gear oil.

Driver Control Center Differential (DCCD)
(WRX STI only)
This electronically controlled system
adjusts the power-distribution ratio
between the front and rear wheels.
The system is designed to provide
optimum differential control for
improved vehicle cornering, stability,
and handling control to suit driving and
road surface conditions. The DCCD
can be operated automatically or
manually. When the system is in the
automatic mode, the “AUTO” indicator
light in the combination meter comes
on. The DCCD can be taken out of
“AUTO” mode and used manually by
pressing the “AUTO MANU” switch
located on the center console. Use the
DCCD control switch located on the
center console for manual operation. Pressing the “AUTO MANU” switch
again will return the system to “AUTO”
mode. When using the system
manually, if the control switch is set
closer to or at the “Lock” position,
the powertrain may make a vibration
or noise when the vehicle is in tight
turns at slow speeds (system binding).
In addition, if the rear differential
oil exceeds a certain temperature,
the DCCD will automatically cancel
the current torque-distribution ratio
setting and adopt its minimum ratio.
SI-Drive (WRX STI only)
Turn the selector toward S for Sport mode or toward S# for Sport Sharp mode.
Press down on the selector for Intelligent mode.
