Driving
■The system can be operated
when
●The power switch is in ON.
●The intuitive parking assist func-
tion is on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●The shift position is in a position
other than P.
■If “Parking Assist Unavailable
Sensor Blocked” is displayed
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 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 an abnormality is displayed even
though there are no water droplets,
ice, snow or dirt, the sensor may be
operating abnormally. Have the
vehicle inspected by your Toyota
dealer.
■If “System Stopped See
Owner’s Manual” is displayed
on the multi-information display
Water may be continuously flowing
over the sensor surf ace, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■If “System Malfunction Visit
Your Dealer” is displayed on
the multi-info rmation display
There may be a sensor or voltage
malfunction. Have the vehicle
inspected by your Toyota dealer.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●Certain vehicle conditions and the
surrounding environment may
affect the ability of a sensor to cor-
rectly detect an object.
●Objects may not be detected if
they are too close to the sensor.
●There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detection
areas before 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 sys-
tems are sounding.
●If the meter malfunctions, the
buzzer may not sound.
WARNING
●Keep your tires properly
inflated.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area. Doing so ma y 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.

■Precautions for the suspen-
sion
Do not modify the suspension of
the vehicle. If the height or tilt of
the vehicle is changed, the sen-
sors may not be able to detect
detectable objects and the system
may not operate correctly, possi-
bly leading to an accident.
NOTICE

4907-1. Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
■Front side windows with UV
protective coating (if equipped)
The front side windows have UV
protective coating. To prevent any
NOTICE
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle using a high pres-
sure car washer.
●Do not use the washer on the
area around the charging port
lid. Water could get into the AC
charging inlet and could dam-
age the vehicle.
Cleaning and protect-
ing the vehicle interior
Perform cleaning in a man-
ner appropriate to each
component and its material.
