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.

■If you press the tire pressure
warning reset switch acciden-
tally
If initialization is performed, adjust
the tire inflation pressure to the
specified level and initialize the tire
pressure warning system again.
■Initialization procedure
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure.
Also, make sure the tires are cold
before carrying out initialization or
tire inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initializa-
tion, it is not necessary to press
the reset switch again as initializa-
tion will restart aut omatically when
the engine switch has been turned
to ON for the next time.
●If you accidentally press the reset
switch when initialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
■When initialization of the tire
pressure warning system has
failed
Initialization can be completed in a
few minutes. However, in the follow-
ing cases, the set tings have not
been recorded an d the system will
not operate properly. If repeated
attempts to record tire inflation pres-
sure settings are unsuccessful,
have the vehicle inspected by your
Toyota dealer.
●When operating the tire pressure
warning reset switch, tire pressure
warning light doe s not blink 3
times.
●After carrying out the initialization
procedure, the tir e pressure warn-
ing light blinks for 1 minute then stays on after driving for 20 min-
utes.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When replac-
ing a tire pressure warning valve
and transmitter, it is necessary
to register the ID code. Have the
ID code registered by your Toy-
ota dealer.
■Registering ID codes
The ID codes of t he tire pressure
warning valve and transmitters for
two sets of whee ls can be regis-
tered.
It is not necessary to register the ID
codes when replacing normal tires
with snow tires, if the ID codes for
the wheels of both normal tires and
snow tires are registered before-
hand.
In addition to the set of tire pressure
warning system sensor ID codes ini-
tially registered to the vehicle, a sec-
ond set of ID codes can be
registered.
A second set of tire pressure warn-
ing system sensor ID codes can be
registered at your Toyota dealer.
WARNING
■When initializing the tire pres-
sure warning system
Do not operate the tire pressure
warning reset switch without first
adjusting the tire inflation pres-
sure to the specif ied level. Other-
wise, the tire pressure warning
light may not come on even if the
tire inflation press ure is low, or it
may come on when the tire infla-
tion pressure is actually normal.
