Make sure to depress the brake
pedal once the vehicle has been
stopped by automatic braking.
Until the brake pedal is
depressed, a message will be
displayed on the multimedia
system screen and the continu-
ous beep will remain sounding.
At this time, a warning message
is also displayed on the
multi-information display.
Depress brake pedal warning“Apply Brake To Hold Posi-
tion”
The Sonar Audible Alarm and Auto-
matic Braking are different in opera-
tion conditions. 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 indi-
cator will illuminate and the sys-
tem will temporarily stop
operating. The RAB OFF indica-
tor 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 lever is
shifted to R.
●The Reverse Automatic Braking
(RAB) system will be disabled in
the following situations.
• When 3 seconds pass after the vehicle is stopped
• When any door is opened
• When the RAB warning light is illu-
minated
• When the RAB OF F indicator is
illuminated
●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 sh ift lever is set
to R
• The system detects sounds of a similar frequency to the RAB
sonar
• When the TRAC and VSC mode are turned off
• When in TRACK mode and the
WARNING
Depress the brake pedal immedi-
ately 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 accident.

When the settings cannot be
changed, the ON/OFF setting key
will be grayed out.
Also, the following settings can be
changed by operating the multime-
dia system screen. (P.400)
●Warning Volume
●Sonar Audible Alarm
●Automatic Braking
If the Reverse Automatic Brak-
ing (RAB) system malfunctions,
the above indicator illuminates
on the meter. Contact the near-
est Toyota dealer for details.
The 4 sonar sensors are located
in the rear bumper. To ensure
the proper operation of the
Reverse Automatic Braking
(RAB) system, observe the fol-
lowing precautions.
 Do not affix any stickers or
other items on the sonar sen-
sor 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-washing machine.
 Do not apply strong impacts
to the rear bumper near the
sonar sensors. If a sensor
becomes misaligned, a sys-
tem malfunction may occur,
including inability to detect
objects in the reversing direc-
tion. If any strong impact is
applied to the rear bumper,
contact a Toyota dealer 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, contact your Toyota
dealer for assistance.

then turn the engine switch
off.
■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.
Registering ID codes

3547-2. Steps to take in an emergency
■Tire pressure warning light (warning buzzer)
■Front passenger detection sen-
sor, seat belt reminder and
warning buzzer
●If luggage is placed on the front
passenger seat, the front passen-
ger detection sensor may cause
the warning light to flash and the
warning buzzer to sound even if a
passenger is not sitting in the
seat.
●If a cushion is placed on the seat,
the sensor may not detect a pas-
senger, and the warning light may
not operate properly.
■If the malfunction indicator
lamp comes on while driving
First check the following:
●Is the fuel t ank empty?
If it is, fill the f uel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go o ff after several
driving trips.
If the light does not go off even after
several trips, contact your Toyota
dealer as soon as possible.
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes
insufficient or the voltage temporar-
ily drops, the electric power steering
system warning light may come on
and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Check the tire inflation pressure and
adjust to the appropriate level.
Pushing the tire pressure warning
reset switch will not turn off the tire
pressure warning light.
■The tire pressure warning light
may come on due to natural
causes
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this ca se, adjusting the
tire inflation pressure will turn off the
warning ligh t (after a few minutes).
■Conditions that the tire pres-
sure warning system may not
function properly
