6-Speed Manual Transmission
This manual transmission is a fully
synchromeshed 6-forward and 1-reverse
speed transmission. Before you can shift into
reverse gear, you must raise the slider ring
and hold it in that position. Only pull the slider
ring up when shifting into reverse gear.
REV Alarm System (WRX STI only)
The REV alarm system automatically issues a
warning using the REV indicator light whenever
the tachometer needle enters the red zone. This
feature can be turned on or off using the multi-
information display. The REV alarm level can be
set manually to an engine speed of your choosing
between 2,000 and 6,700 rpm using the multi-
information display. The multi-information display
is also used to select a warning alarm buzzer in
addition to the light. Please refer to your Owner’s
Manual for more detailed instructions on setting
the engine speed alarm level and selecting the
warning buzzer.

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.

Additional Information
Fuel
• For WRX, use premium unleaded gasoline with an octane rating of 91 AKI or higher. If
91 AKI fuel is not readily available, regular unleaded gasoline with an octane rating of 87
AKI or higher may be temporarily used. However, depending on your driving habits and
conditions, you may notice a decrease in engine performance, fuel economy and slight
engine vibration or knocking. Consult the Owner’s Manual for more detailed information.
• For WRX STI, use premium unleaded gasoline with an octane rating of 93 AKI or higher.
If 93 AKI fuel is not readily available in your area, premium unleaded gasoline with an
octane rating of 91 AKI may be used with no detriment to engine durabili\
ty or driveability.
However, you may notice a slight decrease in maximum engine performance while using
91 AKI fuel. Consult the Owner’s Manual for more detailed information.
Fuel Capacity
• 15.9 US gal (60 liters, 13.2 Imp gal)
• When the low fuel indicator light is displayed on the instrument panel, \
approximately
2.6 US gallons (10.0 liters, or 2.2 Imp gal) of fuel remain.
• If you have recently fueled your vehicle, the check engine light on the instrument pa\
nel
may stay on due to a missing or loose fuel filler cap (the cap should\
be tightened until a
click is heard).
Fuel Filler Lid Release
The fuel filler lid release is located on the floor to the
left of the driver’s seat. To open the fuel filler lid, pull
the fuel filler lever up and release.
