Reverse Automatic
Braking (RAB) system*
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.

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.
The Reverse Automatic Braking
(RAB) system will operate the
following 2 functions using 4
sonar sensors.
Sonar Audible Alarm
The Reverse Automatic Braking
(RAB) system detects objects rear-
ward and warns the driver by warn-
ing message on the multimedia
system screen an d warning beeps.
Automatic Braking
The automatic braking detects
objects rearward and if there is a
high risk of a co llision, the system
decelerates the vehicle and con-
trols the braking to reduce damage.
When reversing
When either strong automatic
braking or torque control is
applied to prevent collision (in
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
driving 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 oper-
ation has limitations. The
warning sound or automatic
braking may 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 vehi-
cle 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 the
vehicle. 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.

●In the following cases, the
Reverse Automatic Braking (RAB)
system cannot be operated.
• The RAB OFF indicator is illumi-
nated.
●In the following cases, the func-
tions may not be able to properly
work. Promptly contact a Toyota
dealer to have the system
inspected.
• A sticker, paint, or a chemical is applied to the sonar sensors or
the rear bumper near the sonar
sensor.
• The rear bumper is modified.
• The rear bumper has been
removed and attached.
• The ground clearance is changed
due to the vehicle’s loading condi-
tion or modification.
• There is damage to the sonar sen-
sors or the rear bumper near the
sonar sensor.
• The rear bumper is exposed to
strong impact, or the rear bumper
is deformed.
●On a steep hill, t he system’s auto-
matic braking ability will be
reduced.
●The system is designed to avoid
collisions by automatic hard brak-
ing when the vehicle’s reversing
speed is less than approximately
3 mph (5 km/h). However, the sys-
tem does not guarantee that the
vehicle will be able to avoid colli-
sions 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 operate.
●The system may not be able to
detect and apply the brake with
the following objects.
• Sharp or thin objects such as poles, fences and ropes which
may not reflect the sound wave
emitted from the sonar sensor.
• Objects that are t oo close to the
rear bumper when the shift lever is set to R.
• Objects with a su rface which may
not reflect the sound wave emitted
from the sonar sensor such as a
chain link fence.
●Objects the system is not
designed to detect and apply
brake.
• Pedestrians.
• Moving objects including moving vehicles.
• Objects which absorbs sound waves such as cloth or snow.
• Objects whose surface has a
diagonal angle.
• Objects that are low to the ground such as parking blocks.
• Objects that are high above the ground such as objects hanging
from above.
• Objects that are out of range of
the center of the vehicle in the
horizontal direction.
• Objects that are n ot in a vertical
direction.
• Objects which are not perpendicu-
lar to the ground.
• Objects which are not directly in the traveling direction of the vehi-
cle.
• Objects which a re uneven or
wavy.
●When reversing the vehicle, the
functions may not be able to work
properly or may cause a system
malfunction if the following condi-
tions exist.
High frequency so und from other
sources are nearby:
• Horn sound from another vehicle.
• Engine sound from other vehicles.
• Sound of an air brake.
• Vehicle detection equipment or a
sonar from another vehicle.
• A sound wave with a frequency similar to the veh icle’s system is
transmitted near by.
• A vehicle equipped with the same system is reversing toward your
reversing direction.
●Weather conditions:
• Extremely high or extremely low
