4-5. Using the driving support systems
4
Driving
■ The system can be operated
when
● The engine switch is in ON.
● Intuitive parking assist function is
on.
● The vehicle speed is less than
about 6 mph (10 km/h).
● The shift lever is in a position
other than P.
■ If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion 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 normal.
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 sys-
tem will return to normal.
If a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle inspected by your Toyota
dealer.
■ If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
● Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will return to normal.
● Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(P.273)
If this message continues to be
displayed even after initialization,
have the vehicle inspected by
your Toyota dealer.
■ If a battery terminal has been
disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■ Sensor detection information
● The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
● The following situations may occur
during use.
• Depending on the shape of the
object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if
static objects draw too close to the
sensor.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibility that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer 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.
WARNING
■ Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
● When using a high pressure
washer to wash the vehicle, do
not spray the sensors 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 sensor to malfunc-
tion.
