■Intuitive parking assist switch
Press the switch to turn the
system on/off.
If the intuitive parking assist is
turned on, the indicator light will
come on, and the system will
operate under the following
conditions:
• The dual sensors will oper- ate if the shift lever is in a
position other than “R” or
“P”.
• All corner sensors and the back sensors will operate if
the shift lever is in “R”.

Sensor detection display, obstacle distance and beepsWhen the intuitive parking assist is activated, the approximate distance to
the obstacle is displayed. Also, if an obstacle with which a collision is pos-
sible is detected, a warning beep will sound.

Steering guide symbolDisplays the steering mane uvers required to avoid an obstacle. Move the
steering wheel in the direction shown by the arrow.
The steering guide symbol only
shows the maneuvers necessary to
avoid an obstacle.
When using the system, always
check your surroundings for
safety.
Beeps and obstacle distance
A beep sounds when an obstacle with which there is a danger of collision
is detected. As the vehicle moves clos er to the obstacle, the interval of
the beep becomes shorter.
● When the following obstacle distan ces are reached, the beep changes
from intermittent to continuous:
• If the distance to the obstacle detected by the dual sensors or rear corner
sensors is less than 0.8 ft. (25 cm).
• If the distance to the obstacle detected by the back sensors is less than 1.1
ft. (35 cm).
● If obstacles are detected by the dual sensors in 2 places at once, or if
both rear corner sensors detect obst acles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.

●If multiple obstacles are detected in front and behind the vehicle at the
same time, the warning beep will change in the following manner:
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected near a different area of th e vehicle, the warning beep will sound
6 beeps then one continuous beep.
• If an obstacle has been detected within 0.8 ft. (25 cm) of the front or rear
of the vehicle (a continuous beep is sounding), and a new obstacle is
detected within 0.8 ft. (25 cm) of a different area of the vehicle, the warn-
ing beeps will sound 2 beeps then one continuous beep.
●You can change the volume of the warning beeps. ( P. 1 8 9 )
Obstacle detection range
About 10.0 ft. (300 cm)
About 3.0 ft. (100 cm)
About 5.0 ft. (150 cm)
About 1.5 ft. (50 cm)
The detection area of the sensors is
shown to the left.
If obstacles move too close to the
sensors, they will not be detected. 
If the malfunction screen is dis-
played, the dual sensor detection
range will be shortened from 3.0 ft.
(100 cm) to 1.5 ft. (50 cm).

■The intuitive parking assist can be operated when
The “POWER” switch is in the ON mode.
■When the system malfunctions
●If a malfunction occurs and no obstacles have been detected, a warning is dis-
played, and a malfunction beep sounds for 7 seconds.
If an obstacle has been detected, or another malfunction occurs in a different
sensor, the malfunction beeps will not sound.
●In the following circumstances the displayed warning will disappear:
• If you switch the screen to a different mode.
• If you turn off the intuitive parking assist main switch.
• If the vehicle speed exceeds 6 mph (10 km/h). Once the vehicle speed drops
below 6 mph (10 km/h), the warning will be displayed again.
●If the malfunction screen is displayed, the detection range of the dual sensors is
shortened. In this case, the necessity fo r obstacle evasion (whether the obstacle
will come within 0.8 ft. [25 cm] of the vehicle or not) will not be calculated.
