The intuitive parking assist can be
enabled/disabled on the
screen ( →P. 231) of the multi-
information display.
When on is selected, intuitive park-
ing assist indicator will come on.
Once off is selected, the intuitive parking assist will not return to on until it
is turned to on by the screen of multi-information display again. (The
system does not automatically return to on even when the hybrid system is
restarted.)
∗: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via the displays and a buzzer.
Always check the surrounding area when using this system.

■If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction” is di splayed on the multi-information dis-
play
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: →P. 732)
WARNING
■When using intuitive parking assist
Observe the following precautions to avoid an unexpected accident.
● Do not exceed the speed limit of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.

When the hybrid system output restriction control or brake control
operates, the buzzer sounds and a message is displayed on the multi-

Depending on the situation, output restriction control operates to either
limit acceleration or restrict output as much as possible.

●Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parking assist
system of another vehicle, a vehicle detector, a motorcycle engine 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
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■ Intelligent Clearance Sonar function while the Simple Advanced Parking
Guidance System is operating
→P. 444
■ When removing and installi ng the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight ahead for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or higher.
■ When “ICS Unavailable” is displayed on the multi-information display
and the ICS 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 due 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 inspected 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 “ICS Malfunction Visit Your Deal er” is displayed on the multi-infor-
mation display, the ICS OFF indi cator flashes and the buzzer sounds
The system may not be operating properly. Have the vehicle inspected at
your Toyota dealer.

■Intelligent Clearance Sonar function while the Simple Advanced Parking
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, hybrid system output
restriction control and brake control of the Intelligent Clearance Sonar func-
tion are operated, regardless of whether the Intelligent Clearance Sonar\
func-
tion is on or off. ( →P. 431)
● After the Intelligent Clearance Sonar function operates, operation of th\
e
Simple Advanced Parking Guidance System is temporarily stopped, and
operation of the Intelligent Clearance Sonar function is indicated on the
multi-information display. ( →P. 435)
● When operation of the Simple Advanced Parking Guidance System is
stopped 3 times by operation of the Intelligent Clearance Sonar function, the
Simple Advanced Parking Guidance System is canceled.
● Once the Simple Advanced Parking Guidance System becomes available
after the Intelligent Clearance Sonar function is operated, a message
prompting you to shift is displayed on the multi-information display. Opera-
tion of the Simple Advanced Parking Guidance System can be resumed by
shifting according to the prompt on the multi-information display and press-
ing the S-APGS switch ( →P. 445) again.
■ Shifting while the Simple Advanced Parking Guidance System is operat-
ing
If the system determines that the drivers intends to move forward or in
reverse, assistance continues even if the drivers 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 increase.
■ Customization
Settings (e.g. Obstacle detection range) can be changed.

This allows you to switch func-
tions and cancel or restart assist
modes.
While the power switch is on, th e vehicle speed is approximately
19 mph (30 km/h) or less, each time the S-APGS switch is pressed
the function switches as follows.
The selected function is indicated on the operation display area of the
multi-information display ( →P. 446).
*: The back-in parking assist mode can be switched to when its operating
conditions are met ( →P. 464). When the operating conditions are not met,
it switches to off.
