■Camera images
As special cameras are used, the
colors in displayed images may dif-
fer from the actual color.
■Detection range of the sensors
●Detection range of the sensors
when using the perpendicular
parking function Target parking space position
●Detection range of the sensors
when using the p
arallel parking
and departure functions
Target parking space position
●If a parked vehicle is behind the
target parking space and the dis-
tance between it and the vehicle
becomes far, it m ay no longer be
able to be detected. Depending on
shape or condition of a parked
vehicle, the detection range may
become short or the vehicle may
not be detected.
●Objects other than parked vehi-
cles, such as columns, walls, etc.,
may not be detecte d. Also, if they

are detected, they may cause the
target parking space to be mis-
aligned.
Select on the multimedia
display, and then select
“Advanced Park”.
■Speed Profile
The vehicle speed for when
parking assistance is performed
can be set.
This setting cannot be changed for

 P. 2 5 5
In addition, please refer to the
“Panoramic view monitor” of
“Peripheral monito ring system” in
the “NAVIGATION AND MULTI-
MEDIA SYSTEM OWNER’S
MANUAL”.
■When the sensors do not
operate properly
●In situations such as the follow-
ing, the sensors may not oper-
ate correctly, possibly leading to
an accident. Proceed carefully.
• When a sensor is frozen. (Thawing the area will resolve
this problem.) In especially cold
weather, if a sensor is frozen
the screen may show an abnor-
mal display, or parked vehicles
may not be detected.
• When the vehicl e is tilted at a
steep angle
• When it is extremely hot or cold
• When driving on rough, sloped, or gravel roads, or grass
• When ultrasonic waves are being produced near the vehicle
due to vehicle horns, motorcy-
cle engines, air brakes of large
vehicles, or the sensors of
another vehicle
• When it is raining or a sensor is splashed by water
• When the area around the vehi- cle is dark or backlit
• When a fender pole or radio antenna has been installed to
the vehicle
• When a sensor is extremely close to a parked vehicle
• When there is a parked vehicle next to the target parking space,
if the displayed target parking
space is far from the actual tar-
get parking space, a sensor
may be misaligned. Have the
vehicle inspected by your Toy-
ota dealer.
• Do not install any accessories near the detection area of the
sensors.
●The Advanced Park will guide
the vehicle to appropriate posi-
tions for changing the direction
of travel, however, if you feel
that the vehicle is approaching
too close to an adjacent parked
vehicle at any time, depress the
brake pedal and change the
shift position. However, if this is
performed, the number of turns
necessary may increase, and
the vehicle may be parked at an
angle.

■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the TRAC/VSC/ABS sys-
tems are operating
The slip indicator light will flash
while the TRAC/VSC/ABS systems
are operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the fuel cell sys-
tem to the wheels. Pressing to
turn the system off may make it eas-
ier for you to rock the vehicle in
order to free it.
To turn the TRAC system off, quickly
press and release .
The “Traction Control Turned OFF”
will be shown on the multi-informa-
tion display. Press again to
turn the system
back on.

●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the fuel
cell system off. The EPS system
should return to normal within 10
minutes.
■Secondary Collision Brake

uations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
