■The windshield wiper and
washer can be operated when
The power switch is in ON.
■Effects of vehicle speed on
wiper operation (vehicles with
rain-sensing windshield wipers)
Even when the wipers are not in
AUTO mode, vehicle speed affects
the time until the drip prevention
wiper sweep occurs.
With low speed windshield wiper
operation selected, wiper operation
will be switched fro m low speed to
intermittent wiper operation only
when the vehicle is stationary.
(However, when the sensor sensitiv-
ity is adjusted to the highest level,
the mode cannot be switched.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●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 b ugs, etc., are
present on the windshield.
●If the wiper is turned to AUTO

Driving
mode while the powe r switch is in
ON, the wipers will operate once
to show that AUTO mode is acti-
vated.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, automatic
operation may not occur. In this
case, operate the wipers in any
mode other than AUTO mode.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
v oi r.
WARNING
■Caution regarding the use of
windshield wipers in AUTO
mode (vehicles with rain-
sensing windshield wipers)
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 any-
thing else do not become caught
in the windshield wipers.
■Caution regarding the use of
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 there is no washer fluid
spray from the nozzle
Damage to the washer fluid pump
may be caused if the lever is
pulled toward you and held con-
tinually.
■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.

WARNING
■Toyota Safety Sense 2.5
The Toyota Safety Sense 2.5 is
designed to operate under the
assumption that the driver will
drive safely, and is designed to
help reduce the impact to the
occupants and the vehicle in the
case of a collision or assist the
driver in normal driving condi-
tions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s su rroundings and
driving safely.

■If a warning message is displayed on the multi-information display
A system may be tempor arily unavailable or there may be a malfu nction in
the system.
●In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will be come operational.
If the message does not disapp ear, contact your Toyota dealer.
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappea r, contact your Toyota dealer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P.401)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc., to clear the obstruction.
When “Pre-Collisio n System Radar
In Self Calibration Unavailable See
Owner’s Manual” is displayed.Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

Driving
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, th e radar may
judge the surrounding environment can not be properly recognize d. In that
case, “Pre-Collision System Unavailable See Owner’s Manual” is dis-
played.

The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
Vehicles
 Bicyclists 
Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
“BRAKE!”
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.230) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high, a
warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.234)
