may have difficulty detecting the fol-
lowing.

– Small motorcycles, bicycles, pe-
destrians, stationary objects on the
road or road side, etc.
– Vehicles with body shapes that
the radar may not reflect (vehicles

with a low body height such as
sports cars or a trailer with no
cargo)
– Vehicles that are not approaching
your vehicle even though they are in
the detection area (either on a
neighboring lane to the rear or be-
side your vehicle when reversing)
(The system determines the pre-
sence of approaching vehicles
based on data detected by the radar
sensors.)
– Vehicles traveling at significantly
different speeds
– Vehicles driving parallel to your
vehicle at almost the same speed
for a prolonged time
– Oncoming vehicles
– Vehicles in a lane beyond the
neighboring lane
– Vehicles travelling at a signifi-
cantly lower speed that you are
trying to overtake

On a road with extremely narrow

lanes, the system may detect vehicles
driving in a lane next to the neighboring
lane.

When the 8-inch audio/navigation

system is performing a software up-
date, the RCTA warning icons may not
be displayed on the audio/navigation
screen until the update is complete.

7-18. Reverse Automatic
Braking (RAB) system (if
equipped)

Reverse Automatic Braking (RAB) 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 automatically.

WARNING

Reverse Automatic Braking
(RAB) is not a system intended
to replace the driver’s responsi-
bility to check surrounding areas
for vehicles or obstacles to avoid
a collision.

The driver is responsible for driv-

ing safely. Before reversing, be
sure to first depress the brake
pedal and visually check the
surroundings.

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

– CONTINUED –

Reverse Automatic Braking (RAB) system

369

and

operating

(372,1)

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 be compro-
mised.

Do not remove the SUBARU gen-

uine navigation and/or audio sys-
tem. If the SUBARU genuine
navigation and/or audio system
is removed, the rear view camera
image and help lines (distance
marker, dynamic guidelines and
vehicle width lines) will no longer
be displayed.

Even if the Reverse Automatic

Braking (RAB) system and object
detection warning is ON, the
visible alert of Reverse Auto-
matic Braking (RAB) system will
not be displayed. However, the
audible alert and its function will
operate.

NOTE

The Reverse Automatic Braking (RAB)
system records and stores the follow-
ing data when automatic braking oper-
ates. It does not record conversations,
personal information or other audio
data.

Reverse Automatic Braking
(RAB) system overview

The 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 acti-
vate.

If the vehicle is further reversed, auto-

matic hard braking will be applied and a
continuous beeping sound will activate.

Reverse Automatic Braking (RAB) system

370

(373,1)

When reversing

When either strong automatic braking or
torque control is applied to prevent
collision (in this case, short warning
beeps or continuous warning beeps will
sound)

When the vehicle is stopped by the
system (in this case, the continuous
beep will remain sounding)

Object (e.g., a wall)

Detecting range

Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width

Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle

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 brake may activate.
