intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor sensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor
●The raindrop sensor judges the
amount of raindrops.
An optical sensor is adopted. It may
not operate properly when sunlight
from the rising or setting of the sun
intermittently strikes the windshield,
or if bugs, etc. are present on the
windshield.
●If the wiper switch is turned to the
position while the power
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●When the sensor sensitivity ring is
turned toward hi gh while in the
“AUTO” mode, the wipers will
operate once to indicate that the
sensor sensitivity is enhanced.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation may not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■Front door opening linked wind-
shield wiper stop function
When is selected and the
windshield wipers are operating, if a
front door is opened while the vehi-
cle is stopped and the P position is
selected, operation of the wind- shield wipers will be stopped to pre-
vent anyone near the vehicle from
being sprayed by water from the
wipers. When the front door is
closed, wiper operation will resume.
■If no windshield washer fluid
sprays
Check that the washer nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
voir.
WARNING
■Caution regarding the use of
windshield wipers in “AUTO”
mode
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that your fingers or
anything else do not become
caught in the windshield wipers.
■Caution regarding the use of
windshield cleaning washer
fluid
When it is cold, do not use the
washer fluid until the windshield
becomes warm. The fluid may
freeze on the windshield and
cause low visibility. This may lead
to an accident, resulting in death
or serious injury.
NOTICE
■When the washer fluid tank is
empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.

NOTICE
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the hybrid
system is off.

2805-4. Refueling
1Press the opener switch to
open the fuel filler door.
The fuel filler door will open within
about 10 seconds of the switch
being pressed. Before refueling is possible, a message will be shown
on the multi-information display in
the instrument clus
ter to indicate
the progress of the fuel filler door
opener.
2 Turn the fuel tank cap slowly
to open and hang it on the
back of holder on the fuel
filler door.
■If the fuel filler door cannot be
opened
Consult your Toyota dealer.
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
WARNING
●Do not top off the fuel tank.
NOTICE
■Refueling
●Finish refueling within 30 min-
utes. If more than 30 minutes
passes, the internal valve
closes. In this condition, fuel
may overflow during the refuel-
ing process. Press the fuel filler
door opener switch again.
●Make sure that the fuel filler
door lock is not pushed by the
fuel nozzle boot, etc. If the lock
is held, the internal valve closes
and fuel may overflow. To pre-
vent it, press the fuel filler door
opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehi-
cle, such as causing the emis-
sion control system to operate
abnormally or damaging fuel
system components or the vehi-
cle’s painted surface.

driver monitor camera detects
the position and direction the
driver is facing, and whether
their eyes are opened or closed.
Through this, the system deter-
mines if the driver is checking

driver can perform driving oper-
ations.

■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).

■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.
