7-21. 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 their surroundings
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 –

and

Operating

(400,1)

be delayed or may not operate at
all even when an obstacle is
present.

Make sure to set the Automatic

Braking to OFF when the vehicle
is on the free roller or on the
chassis dynamometer. Other-
wise, the vehicle may move and
it may cause an accident.

Make sure to set the Automatic

Braking to OFF when towing a
trailer. Otherwise, the vehicle
may move and it may cause an
accident.

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.

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.

SUBARU and third parties contracted
by SUBARU will not disclose or provide
the acquired data to any other third
party except under the following con-
ditions.

The vehicle owner has given his/her

consent.

Reverse Automatic Braking
(RAB) System Overview

The Reverse Automatic Braking (RAB)
system will operate the following 2 func-
tions using 4 sonar sensors.

Sonar Audible Alarm

The Reverse Automatic Braking (RAB)
system detects objects rearward and
warns the driver by warning message on
the center information display and warning
beeps.

Automatic Braking

The automatic braking detects objects
rearward and if there is a high risk of a
collision, the system decelerates the ve-
hicle and controls the braking to reduce
damage.

Reverse Automatic Braking (RAB) System

398

(401,1)

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)

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 brake may activate. In
this case, remain calm and either
continue to depress the accelerator
pedal or cancel the system. To
cancel the system, refer to “Cancel-
ing the Reverse Automatic Braking
(RAB) System Operation”
