●Sonar Audible Alarm
●Automatic Braking
If the Reverse Automatic Braking
(RAB) system malfunctions, the
above indicator illuminates on the
meter. Contact the nearest any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer 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 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.

ID codes can be registered.
A second set of tire pressure warning system sensor ID codes can be regis-
tered at your Toyota dealer or repairer,

have been registered, either ID code set
can be selected.
