Automatic Transmission Shift Modes (if equipped)
The automatic transmission gives you vehicle control with two different driving
modes: Normal Mode and Manual Mode.
Normal Mode
When the selector lever is in the “D” (Drive) position, the tran\
smission is in
Normal shift mode. The shift position indicator on the instrument panel \
shows
“D”, and the transmission automatically shifts into a suitable for\
ward gear.
Manual Mode
In Manual Mode, you select the desired gear position to obtain necessary
acceleration and engine braking. Moving the selector lever left into the\
manual
gate
1 from the “D” (Drive) position causes the transmission to change in\
to
Manual Mode. To shift, use the paddle shift control switches. The shift position
indicator shows the selected gear position.

the switch again. While the Auto Vehicle
Hold function is operating, the Auto
Vehicle Hold operation indicator light
on the instrument panel will illuminate.
Electronic Parking Brake

To apply, push the brake pedal and pull
up the parking brake switch. The brake
system warning light on the instrument
panel and the indicator light on the
parking brake switch will illuminate.
To release, make sure all doors are
closed and your seatbelt is fastened,
then gently push the accelerator pedal.

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.

3033672_18b_WRX_WRX_STI_QG_051617.indd 225/16/17 2:30 PM

23
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.

Safety/In Case of Emergency
Child Restraint System
For maximum safety, first carefully read the LATCH system instructions from the
device manufacturer, as well as the installation instructions in your Owner’s Manual,
to properly install the LATCH compatible restraint system. Use the appropriate
seatbelts or anchorages provided in your vehicle. Children age 12 and under must
properly occupy the rear seat at all times.
Internal Safety Trunk Release with
Self-Illuminating Handle
In the event that children or adults become locked
inside the trunk, this luminescent handle allows them
to open the lid from inside the trunk. To open, simply
pull the yellow handle downward as indicated by the
arrow on the handle, and then push up on the lid.
Child Safety Locks
The child safety locks are located on the inside edges of the rear doors. In the locked position,
the rear doors can only be opened from the outside.

Location of
Spare Tire and Jack
A jack and other maintenance tools are
stored in the tool bucket in the center
of the spare tire, located in the trunk or
cargo area.
Emergency Towing Your
All-Wheel Drive Vehicle
Since Subaru Symmetrical All-Wheel
Drive distributes engine power to
all four wheels, improper towing
will severely damage your AWD
system. A flatbed truck is the only
recommended way to properly
transport your AWD vehicle. If towing
is necessary, it is best done by your
Subaru Retailer or a commercial
towing service.
