■The intuitive parking assist can be oper-
ated when
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P
or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Front corner sensors:
• The engine switch is in IGNITION ON
mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than about 6
mph (10 km/h).
(At any speed when the shift lever is in R)
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Muting the buzzer sound
●To mute the buzzer sound:
The buzzer can be temporarily muted by
pressing “OK” of the meter control
switches while an obstacle detection dis-
play is shown on the multi-information dis-
play.
●To cancel the mute:
Mute will be automatically canceled in the
following situations.
• When the shift position is changed (except shifting from D to N, or N to D).
• When the vehicle speed has reached or exceeded 6 mph (10 km/h) with the shift
position in D.
• When the intuitive par king assist is turned
off once and turned on again. • When the engine switch is turned off
once and turned to IGNITION ON
mode again.
■If “Clean Parking Assist Sensor” is dis-
played on the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■Sensor detection information
●The following situations may occur
during use.
• The sensors may be able to only detect objects near the fron t and rear bumpers.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and di splay. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other systems are sounding.
■Conditions under wh ich the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
WARNING
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.

curves.
When not in SPORT S mode, if the driving
mode select switch is turned to the right,
the “SPORT S” indicator will come on.
•SPORT S+ mode
