Intuitive parking assist
: If equipped
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the multi-information display, the touch screen,
and warning beeps.
The system may be used at speeds less than about 6 mph (10 km/h).
■Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, and one in each corner of the bumper,
to detect obstacles in those areas.
The dual sensors detect obstacles ahead of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.

Multi-information display and touch screen
If the sensors detect an obstacle, it is displayed on the multi-information
display in the instrument cluster.
You can change the conditions under which information is displayed on
the touch screen. (P. 2 5 8 )

Sensor detection display, obstacle distance and beeps
When 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.
■Dual sensor
• If the shift lever is in “R”, only the corner sensors will detect obstacles.

Steering guide symbol
Displays the steering maneuvers 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 closer to the obstacle, the interval of
the beep becomes shorter.
●When the following obstacle distances 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 obstacles at the same time, the system
will sound a warning beep for the closer of the 2 obstacles.

■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 for obstacle evasion (whether the obstacle
will come within 0.8 ft. [25 cm] of the vehicle or not) will not be calculated.
■When using the intuitive parking assist
●The sensors’ detection areas and reaction times are limited. When moving for-
ward 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.
• The sensors’ detection areas are limited to the areas around the vehicle’s front
and rear bumpers.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the obstacle will come within 0.8 ft. (25
cm) of the vehicle before the display is shown and the warning beep sounds.
• Braking distance may differ according to the road conditions (rain, gravel
etc.).
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of air conditioning system.
• For long obstacles such as walls, the obstacle warning may change as the
obstacle gets closer.

●In the following situations, the intuitive parking assist may not function correctly,
possibly leading to an accident.
• There is ice, snow or mud on the sensors. (Wiping the sensors will resolve this
problem.)
• The sensor area 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 obstacles may not be detected.
• The vehicle angle is especially wide.
• In harsh sunlight or intense cold weather.
• When driving on bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as another
vehicle’s horn, motorcycle engine noise, air braking sound from heavy-duty
vehicles, or another vehicle using the intuitive parking assist.
• In heavy rain, or if water is splashed on the sensors.
• If a commercial fender pole or radio antenna is installed.
• If towing eyelet is installed on your vehicle.
• If moving towards a high curb or a curb corner.
• Objects such as signs may cause the detection distance to shorten.
• The area directly under the bumpers is not detected.
Objects lower than the sensors or thin stakes etc. may be detected initially,
but as they draw closer, they may cease to be detected.
• If obstacles draw too close to the sensor.
■Obstacles that may not be detected correctly
The following obstacles may not be detected.
●Thin objects such as wire, fencing or rope.
●Objects that absorb sound waves, such as cotton or snow.
●Objects with sharp corners.
●Objects where the upper section projects out over the lower section.
●Low objects.
