*: If equipped
The Reverse Automatic Braking (RAB)
system records and st ores 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
●Shift lever position
●Outside temperature
●The sensitivity setting of the sonar
sensors
Toyota and third parties contracted by Toyota may acquire and use the
recorded data for the purpose of vehicle
research and development. Toyota and third parties contracted by Toyota 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 enforcea-

Reverse Automatic Brak-
ing (RAB) system*
Reverse Automatic Braking
(RAB) is a system designed to
help avoid collisions or reduce
collision damage when revers-
ing 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 acti-
vate the vehicle’s brakes auto-
matically.

●Data that has been modified so that
the user and vehicle cannot be identi- fied is provided to a research institu-
tion for statistical processing or similar
purposes.
The Reverse Automatic Braking
(RAB) system will operate the fol-
lowing 2 functions using 4 sonar
sensors.
Sonar Audible Alarm
The Reverse Automatic Braking (RAB)
system detects objec ts rearward and
warns the driver by warning message
on the multimedia system screen 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
vehicle and controls the braking to
reduce damage.
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)

●Reverse Automatic Braking (RAB)
is not a system intended to replace
the driver’s responsibility to check
their surroundings for vehicles or obstacles to avoid a collision.
●The driver is responsible for driving safely. Before revers ing, be sure to
first depress the brake pedal and
visually check the surroundings.
●There are some cases in which the
vehicle cannot avoid collision, because the system operation 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 vehicle is
on the free roller or on the chassis dynamometer. Otherwise, the vehi-
cle 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 children),
animals or other moving objects.
●Depending on the vehicle condition
or the surrounding environment, the sonar sensor’s ability to detect
objects may become unstable.

If your vehicle is trapped on a railroad crossing and you are trying to escape
by reversing through the crossing
gate, the system may recognize the crossing gate as an obstacle and
brake may activate. In this case,
remain calm and either continue to depress the accelerator pedal or can-
cel the system. ( P.241)

When Reverse Automatic Braking (RAB) system is in operation, an audible
warning beeps will sound in 3 levels to warn the driver of a potential colli-
sion.
It may take time to display the wall and sound warning beeps after the object was
recognized by the Sonar Audible Alarm.
*: Range of detection may vary depending on the environmental condition.
■Obstacle detected and alert
level
When an object is detected in the
reversing direction, the range of
detected object will be shown on
the multimedia system screen.
A warning alarm will sound and,
depending on the speed, either
torque control to generate engine
braking or automati c braking will be
applied.

Depress brake pedal warning
“Apply Brake To Hold Position”
The Sonar Audible Alarm and Automatic
Braking are different in operation condi-
tions. Therefore there are cases in which only one of these functions will
activate.
■After the vehicle is stopped by
the system
After the brake pedal is depressed,
the RAB OFF indicator will illumi-
nate and the syst em will temporar-
ily stop operating. The RAB OFF
indicator will turn off when the shift
lever is shifted to a position other
than R.
The system will operate again the
next time the shift le ver is shifted to
R.
●The Reverse Automatic Braking (RAB) system will be disabled in the
following situations.
• When 3 seconds pass after the vehi- cle is stopped
• When any door is opened
• When the RAB warning light is illumi- nated
• When the RAB OFF indicator is illumi-
nated
●The Reverse Automatic Braking
(RAB) system may stop operating temporarily in the following cases and
the RAB OFF indicator will illuminate.
• Ice, snow or mud is adhered to the sonar sensors or the rear bumper
near the sonar sensor
• Objects are too close to the rear bumper when the shift lever is set to R
• The system detects sounds of a simi-
lar frequency to the RAB sonar • When the TRC and VSC mode are
turned off
• When in TRACK mode and the Pre-Collision Braking System has
been turned off
The Reverse Automatic Braking
(RAB) system can be temporarily
canceled by any of the following
operation.
While the vehicle is stopped by
WA R N I N G
Depress the brake pedal immediately after the system stops the vehicle by
automatic braking. Depending on the
conditions of the road surface and
tires, the vehicle may not remain stopped, possibly leading to an acci-
dent.

The 4 sonar sensors are located in
the rear bumper. To ensure the
proper operation of the Reverse
Automatic Braking (RAB) system,
observe the following precautions.
Do not affix any stickers or other
items on the sonar sensor or the
bumper surface near the sonar
sensors.
Always keep the sonar sensor
and the rear bumper surface
near the sonar sensors clean.
Do not modify rear bumper.
Do not paint the bumper near the
sonar sensors.
Do not apply high pressure water
to the sonar sensors with a high
pressure car-wa shing machine.
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, con-
tact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer
to have the system inspected.
Do not disassemble the sonar
sensors.
If the sonar sensors require repair or replacement, or if the area of the rear
bumper near the sonar sensors requires
repair, paintwork or replacement, con- tact any authorized Toyota retailer or
Toyota authorized repairer, or any relia-
ble repairer for assistance.
