■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washe r fluid in the
windshield washer fluid reservoir.
WARNING
■ Caution regarding the use of wind shield wipers in “AUTO” mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take car e that your
fingers etc. anything else does not become caught in the windsh ield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When there is no washer flu id spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is p ulled
toward you and held continually.
■ When a nozzle becomes blocked
Do not try to clear it with a pin or other object. The nozzle w ill be damaged.

WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to
an accident resulting in death or serious injury.
● Keep the radar sensor and radar sensor cover clean at all times .
● Do not attach accessories, stickers (including transparent stic kers) or
other items to the radar sensor, radar sensor cover or surround ing area.
● Do not subject the radar sensor or its surrounding area to a st rong impact.
If the radar sensor, front grille, or front bumper has been sub jected to a
strong impact, have the vehicle inspected by your Toyota dealer .
● Do not disassemble the radar sensor.
● Do not modify or paint the radar sensor cover.
● In the following cases, the radar sensor must be recalibrated. Contact your
Toyota dealer for details.
• When the radar sensor or front grille are removed and installed, or
replaced
• When the front bumper is replaced
Radar sensor
the radar sensor cover
If the front of the radar sensor or the
front or back of the radar sensor cover
is dirty or covered with water droplets,
snow, etc., clean it.
Clean the radar sensor and radar sen-
sor cover with a soft cloth to avoid
damaging them.1

■If a warning message is displayed on the multi-information disp lay
A system may be temporarily 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 become operational.
If the message does not disappear, contact your Toyota dealer.
SituationActions
When the area around a sensor
is covered with dirt, moisture
(fogged up, covered with con-
densation, ice, etc.), or other
foreign matterTo clean the part of the windshield in front
of the front camera, use the windshield
wipers or the windshield defogger of the
air conditioning system ( P. 399).
When the temperature around
the front camera is outside of
the operational range, such as
when the vehicle is in the sun or
in an extremely cold environ-
ment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehi-
cle was parked, depending on its type,
the sunlight reflected from the surface
of the sunshade may cause the tem-
perature 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 conditioning
system to increase the temperature
around the front camera.
The area in front of the front
camera is obstructed, such as
when the hood is open or a
sticker is attached to the part of
the windshield in front of the
front camera.
Close the hood, remove the sticker, etc.
to clear the obstruction.

PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a radar sensor and front camera
to detect vehicles and pedestrians in front of your vehicle. Wh en
the system determines that the possibility of a frontal collisi on
with a vehicle or pedestrian i s high, a warning operates to urg e
the driver to take evasive action and the potential brake pres-
sure is increased to help the driver avoid the collision. If the sys-
tem determines that the possibi lity of a frontal collision with a
vehicle or pedestrian is extremely high, the brakes are automat i-
cally applied to hel p avoid the collision or help reduce the
impact of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 2 5 8 )

■Situations in which the syst em may not operate properly
● In some situations such as the following, a vehicle may not be detected by
the radar sensor and front camera, preventing the system from operating
properly:
• If an oncoming vehicle is approaching your vehicle
• If a vehicle ahead is a motorcycle or bicycle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unload ed truck
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahe ad
• If a vehicle cuts in front of your vehicle or emerges from bes ide a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden sw erving,
acceleration or deceleration)
• When suddenly cutting behind a preceding vehicle
• When driving in inclement weather such as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the surrounding brightness changes sud- denly, such as at the entrance or exit of a tunnel
• If a preceding vehicle has a low rear
end, such as a low bed trailer
• If a vehicle ahead has extremely high ground clearance
• When a vehicle ahead is not directly in front of your vehicle

4-5. Using the driving support systems
• When a very bright light, such as the sun or the headlights of oncoming
traffic, shines directly into the front camera
• When the surrounding area is dim, such as at dawn or dusk, or while at
night or in a tunnel
• After the engine has started the vehicle has not been driven for a certain amount of time

the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
