●Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
sensors of another vehicle, a vehicle detector, a motorcycle en gine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluo- rescent types), fog lights, a fender pole or a wireless antenna ) are
installed near the sensors
● Changes in the vehicle
• When driving with the shift position in N
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the c arried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact

Guidance System is operating
P. 388
■ When removing and instal ling the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight a head for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or hi gher.
■ When “PKSB Unavailable” is displayed on the multi-information display
and the PKSB OFF indicator flashes
●Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, a warning message may be displayed at low temperatures du e to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.
● If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle i nspected at
your Toyota dealer.
● System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■ When “PKSB Malfunction Visit Your Dealer” is displayed on the m ulti-
information display, the PKSB OFF indicator flashes and the buz zer
sounds
The system may not be operating properly. Have the vehicle inspected at
your Toyota dealer.

■Parking Support Brake function while the Simple Advanced Parkin g
Guidance System is operating
While the Simple Advanced Parking Guidance System is operating, if the sys-
tem detects an obstacle that could result in a collision, hybri d system output
restriction control and brake control of the Parking Support Br ake function are
operated, regardless of whether the Parking Support Brake funct ion is on or
off. ( P. 375)
● After the Parking Support Brake function operates, operation of the Simple
Advanced Parking Guidance System is temporarily stopped, and operation
of the Parking Support Brake function is indicated on the multi -information
display. ( P. 379)
● When operation of the Simple Advanced Parking Guidance System i s
stopped 3 times by operation of the Parking Support Brake funct ion, the
Simple Advanced Parking Guidance System is canceled.
● Once the Simple Advanced Parking Guidance System becomes availa ble
after the Parking Support Brake function is operated, a message prompting
you to shift is displayed on the multi-information display. Ope ration of the
Simple Advanced Parking Guidance System can be resumed by shift ing
according to the prompt on the multi-information display and pr essing the
S-APGS switch ( P. 389) again.
■ Shifting while the Simple Advanced Parking Guidance System is operat-
ing
If the system determines that the driver intends to move forwar d or in reverse,
assistance continues even if the driver shifted before being prompted to do so
by the system. However, because driver operation differs from the guidance
provided by the system, the number of turning maneuvers may inc rease.
■ Customization
Settings (e.g. obstacle detection range) can be changed. (Custo mizable fea-
tures: P. 690)

■Function summary
If a parking space can be detected, you will be guided forward until
you reach the assist control star ting position, and then the parallel
parking assist mode can be us ed. Furthermore, depending on the
parking space and other conditions, multi-turn maneuvering assi st
control is also prov ided if necessary.
Continue moving forward
with the vehicle parallel to
the curb or road, and stop so
that the center of the target
parking spot appears nearly
perpendicular to the vehicle.
Then press the S-APGS
switch 1 time to select the
parallel parking assist mode.
Travel straight ahead paral-
lel with the road or curb so
that the parking space is
detected.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position wher e assist control can be used to
begin backing up from, and then when the shift position is
changed according to guidance provided by the system, steering
wheel auto oper ation begins.
If the detected parking space or road width (distance to the si de of the
road across from the parking space) is narrow, or if there are obstacles
in front of the vehicle, guidance will not be issued.
Parking is complete
This completes the assist mode. Depending on the condition of t he
parking space, guidance to starting points for moving forward and back-
ing up, as well as the steering wheel auto operation, are repea ted any
time multi-turn maneuvering is necessary following step from the
time the vehicle begins backing up until parking completes.
