INTUITIVE PARKING ASSIST
G31049
The intuitive parking assist is a warning system used
when parking the vehicle at low speed (e.g. into a garage).
It uses an ultrasonic sensor, which checks the
approximate distance to an obstacle. It will inform you of
the approximate distance to an obstacle by displaying
information on the multiinformation display and the
screen, and with beeping sounds.
1 Dual sensors
There are four of these steering guidance sensors installed in
the front bumper.
Steering guidance means that when an obstacle is inspected,
not only is the distance estimated, this function judges whether
collision with the obstacle within detection range is avoidable
if the vehicle is steered in a certain direction, and informs the
driver. There will be no warning if it judges that there is no
possibility of collision with the obstacle within detection range.
(See page 375.)
2 Rear corner sensors
There is one of these installed on each corner of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 380.)
3 Back sensors
There are two of these installed near the center of the rear
bumper, they inspect obstacles and will sound a warning
depending on the distance to the obstacle. (See page 381.)

To use the intuitive parking assist, push the main switch
in the switch box with the engine switch in “IGON” mode.
Pushing the main switch again will turn the intuitive
parking assist off.
When you push the main switch, the indicator light in the
instrument cluster comes on and a beep sounds for one
second, indicating that the intuitive parking assist is turned on.
The intuitive parking assist will remain on even after turning the
engine switch to “OFF” and then to “IG−ON” mode with the
main switch on. However, a beep does not sound at this time.
If an error is detected in the intuitive parking assist while
self−checking, beeps sound and a warning appears in the
multi−information display and on the screen. For details, see
“Intuitive parking assist failure warning” on page 385.

When an obstacle is detected, the indicator bars will come
on or flash, accompanied by beeping. How many bars are
lit or flashing depends on the distance to the obstacle.
When the obstacle is not detected any longer, beeps will stop
sounding and the multi −information display and the screen will
return to the previous display.
The volume of the beeps and the display on the screen can be
changed. See “Setting the intuitive parking assist” on page
391.

The approximate distance to the obstacle is shown with up to
4 bars on the front, front corners and rear of the vehicle and up
to 3 bars on the rear corners of the vehicle.

1Multiinformation display:
The indicator bars will come on depending on the
distance to the obstacle and will flash when the distance
between the vehicle and the obstacle is less than about
25 cm (0.8 ft.).
2 Screen:
The indicator bars will come on in yellow according to the
distance to the obstacle. When the distance between the
vehicle and the obstacle is less than about 25 cm (0.8 ft.),
the yellow indicator bars will turn red. In addition, the
current direction of the tires is also indicated in 3 stages.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.). (B) Collision will be avoided by changing the steering

The steering guide symbol and the arrow indicating which
direction should be steered appear along with the bar
indicators and beeps.

STARTING AND DRIVING
378The above illustration indicates that the collision will be
avoided by turning the steering wheel clockwise.
When
the possibility that the distance between the vehicle and
the obstacle is less than about 25 cm (0.8 ft.) is eliminated by
turning the steering wheel more, the steering guide symbol will
go out and the beeps will stop sounding.
The steering guide symbol and arrow are not instructions
you must observe. They are just a guide to avoid a
collision.

The indicator bars will come on depending on the
distance to the obstacle . The steering guide symbol and
arrow will also come on.
2Screen:
The indicator bars will come on in yellow depending on
the distance to the obstacle. The steering guide symbol
and arrow will also come on. In addition, the current
direction of the tires is also indicated in 3 stages.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).
CAUTION
When an obstacle is detected within about 25 cm (0.8 ft.)
from the vehicle, the dual sensors will change the
determination to an unavoidable collision. To avoid an
accident or injury, be sure to confirm a safe distance
around your vehicle with your eyes and drive slowly.

CAUTION
To avoid an accident or injury, observe the following.
When you move your vehicle, be sure to confirm a safe
distance around your vehicle with your eyes and drive
slowly.
 With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is
changed; from certain avoidance to unavoidable
collision; and there are also times when the decision
will be changed from avoidance if steering is
changed, to certain collision.
 When an obstacle is detected within about 25 cm (0.8
ft.) from the vehicle, the dual sensors will change the
determination to an unavoidable collision.
