Cruise controlNOTEFor models with the EyeSight system:
Refer to the Owner’s Manual supple-
ment for the EyeSight system.
Cruise control enables you to maintain a
constant vehicle speed without holding
your foot on the accelerator pedal and it is
operative when the vehicle speed is 20
mph (30 km/h) or more.
WARNING
.Do not use the cruise control
under any of the following condi-
tions. These may cause loss of
vehicle control.
–driving up or down a steep
grade
–driving on slippery or winding
roads
–driving in heavy traffic
.When using the cruise control,
always set the speed appropri-
ately according to the speed limit,
traffic flow, road conditions, and
other conditions.
NOTE.On uphill and downhill slopes, de-
pending on the degree of the slope and
the load of the vehicle, there may be
cases when a constant speed cannot
be guaranteed.
.If the cruise control indicator does
not appear even after pressing the
cruise control main button, it is possi-
ble that there is a malfunction in the
system. We recommend that you con-
tact your SUBARU dealer for an inspec-
tion.
.Make sure the cruise control system
is turned off when the cruise control is
not in use to avoid unintentionally
setting the cruise control.

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.

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

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

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.

.On a steep hill, the system’s auto-
matic braking ability will be reduced.
.The system is designed to avoid
collisions by automatic hard braking
when the vehicle’s reversing speed is
less than approximately 3 mph (5 km/h).
However, the system does not guaran-
tee that the vehicle will be able to avoid
collisions in any situation.
.If the vehicle is reversed at an
extremely slow speed, the driver’s
operation may be prioritized. In this
case, automatic braking will not oper-
ate.

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
