aligned, a system malfunction
may occur, including the inability
to detect vehicles entering the
detection areas. If any strong
shock is applied to the bumper,
be sure to contact your SUBARU
dealer for inspection.
–Do not disassemble the radar
sensors.
NOTEIf the radar sensors require repair or
replacement, or the bumper area
around the radar sensors requires
repair, paintwork or replacement, con-
tact your SUBARU dealer for assis-
tance.
Reverse Automatic Braking
System (if equipped)Reverse Automatic Braking is a system
designed to help avoid collisions or reduce
collision damage when reversing the
vehicle. If a wall or an obstacle is detected
in the reversing direction, the system will
notify the driver with a warning sound and
may activate the vehicle’s brakes auto-
matically.
WARNING
.Reverse Automatic Braking is not
a system intended to replace the
driver’s responsibility to check
surrounding areas for vehicles or
obstacles to avoid a collision.
.The driver is responsible for driv-
ing safely. Always be sure to
check the surroundings visually
when reversing the vehicle.
.There are some cases in which
the vehicle cannot avoid colli-
sion, because the system opera-
tion has limitations. The warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present..The system is not designed to
detect people (including chil-
dren), animals or other moving
objects.
.Depending on the vehicle condi-
tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may become
unstable.
NOTEThe Reverse Automatic Braking Sys-
tem records and stores the following
data when automatic braking operates.
It does not record conversations, per-
sonal information or other audio data.
.Distance from the object
.Vehicle speed
.Accelerator pedal operation status
.Brake pedal operation status
.Select lever position
.Outside temperature
.The sensitivity setting of the sonar
sensors
SUBARU and third parties con-
tracted by SUBARU may acquire
and use the recorded data for the
purpose of vehicle research and
development. SUBARU and third
parties contracted by SUBARU will

not disclose or provide the acquired
data to any other third party except
under the following conditions.
–The vehicle owner has given his/
her consent.
–The disclosure/provision is
based on a court order or other
legally enforceable request.
–Data that has been modified so
that the user and vehicle cannot be
identified is provided to a research
institution for statistical processing
or similar purposes.
&Reverse Automatic Braking
System overviewThe system detects objects using sonar
sensors installed in the rear bumper. If the
system determines a possible collision
with an object in the reversing direction,
automatic deceleration will be activated.
Also, beeping sounds will activate. If the
vehicle is further reversed, automatic hard
braking will be applied and a continuous
beeping sound will activate.!Detecting range
1) Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width
2) Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle
3) Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle
WARNING
If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brakes may acti-
vate. In this case, remain calm and
either continue to depress the accel-
erator pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking
system operation”F7-74.

malfunctions, the above indicator illumi-
nates on the combination meter. Contact
the nearest SUBARU dealer for details.
&Handling of the sonar sen-
sorsThe 4 sonar sensors are located in the rear
bumper. To ensure the proper operation of
the Reverse Automatic Braking system,
observe the following precautions..Do not affix any stickers or other items
on the sonar sensors or the bumper
surface near the sonar sensors.
.Always keep the sonar sensors and the
rear bumper surface near the sonar
sensors clean.
.Do not modify the rear bumper.
.Do not paint the bumper near the sonar
sensors.
.Do not apply strong impacts to the rear
bumper near the sonar sensors. If a sensor
becomes misaligned, a system malfunc-tion may occur, including inability to detect
objects in the reversing direction. If any
strong impact is applied to the rear
bumper, contact a SUBARU dealer to
have the system inspected.
.Do not disassemble the sonar sensors.
NOTEIf the sonar sensors require repair or
replacement, or if the area of the rear
bumper near the sonar sensors re-
quires repair, paintwork or replace-
ment, contact your SUBARU dealer for
assistance.

New vehicle break-in driving–
the first 1,000 miles (1,600 km)The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
.Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency.
.Do not drive at one constant engine or
vehicle speed, either fast or slow.
.Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
.Avoid hard braking, except in an emer-
gency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones.
Fuel economy hintsThe following suggestions will help to save
fuel.
.Select the proper gear position for the
speed and road conditions.
.Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as possi-
ble.
.Do not pump the accelerator and avoid
racing the engine.
.Avoid unnecessary engine idling.
.Keep the engine properly tuned.
.Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on the
driver’s side. Low pressure will increase
tire wear and fuel consumption.
.Use the air conditioner only when
necessary.
.Keep the front and rear wheels in
proper alignment.
.Avoid carrying unnecessary luggage or
cargo.
.The indication of the ECO gauge shows
a reference for saving fuel. For details,
refer to“ECO gauge”F3-12.
Engine exhaust gas (carbon
monoxide)
WARNING
.Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
.Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from entering
the vehicle.
.Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
.Avoid remaining in a parked ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion fan to force fresh air into the
vehicle.
.Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
.If at any time you suspect that

exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
.Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
Catalytic converterSTIExcept STIThe catalytic converter is installed in the
exhaust system. It serves as a catalyst toreduce HC, CO and NOx in exhaust gases,
thus providing cleaner exhaust.
To avoid damage to the catalytic converter:
.Use only unleaded fuel. Even a small
amount of leaded fuel will damage the
catalytic converter.
.Never start the engine by pushing or
pulling the vehicle.
.Avoid racing the engine.
.Never turn off the ignition switch while
the vehicle is moving.
.Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
.Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-
tem.
.Do not drive with an extremely low fuel
level.
WARNING
.Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.,
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-
