■If a warning message is dis-
played on the multi-information
display
A system may be temporarily
unavailable or there may be a mal-
function in the system.
●In the following situations, perform
the actions specif ied in the table.
When the normal operating condi-
tions are detecte d, 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, cov-
ered with con-
densation, ice,
etc.), or other
foreign matter
To clean the part
of the wind-
shield in front of
the front camera,
use the wind-
shield wipers or
the windshield
defogger of the
air conditioning
system ( P.505,
512).When the tem-
perature around
the front camera
is outside of the
operational
range, such as
when the vehi-
cle is in the sun
or in an
extremely cold
environment
If the front cam-
era is hot, such
as after the vehi-
cle 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, depend-
ing 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 cam-
era is cold, such
as after the vehi-
cle is parked in
an extremely
cold environ-
ment, use the air
conditioning sys-
tem to increase
the temperature
around the front
camera.
SituationActions

2304-5. Using the driving support systems
●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 mes-
sage will disappea r and the sys-
tem will become o perational.
If the message does not disappear,
contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the
operational range, such as when
the vehicle is in the sun or in an
extremely cold environment
• When the front camera cannot
detect objects in front of the vehi-
cle, such as when driving in the
dark, snow, or fog, or when bright
lights are shinin g into the front
camera
The system can detect the fol-
lowing:
 Vehicles
 Bicyclists
 Pedestrians
The area in front
of the front cam-
era is
obstructed, such
as when the
hood is open or
a sticker is
attached to the
part of the wind-
shield in front of
the front camera.
Close the hood,
remove the
sticker, etc. to
clear the
obstruction.
SituationActionsPCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.229) 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
collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.232)
Detectable objects

2364-5. Using the driving support systems
• When approaching an electric toll gate barrier, parking area barrier,
or other barrier that opens and
closes
• When using an automatic car wash
• When driving through or under
objects that may contact your
vehicle, such as thick grass, tree
branches, or a banner
• When driving through steam or smoke
• When driving near an object that reflects radio waves, such as a
large truck or guardrail
• When driving near a TV tower,
broadcasting station, electric
power plant, or other location
where strong radio waves or elec-
trical noise may be present
■Situations in which the system
may not operate properly
●In some situations such as the fol-
lowing, an object may not be
detected by the radar sensor and
front camera, preventing the sys-
tem from operating properly:
• When a detectable object is
approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden
swerving, accelera tion or deceler-
ation)
• When your vehicle approaches a detectable object rapidly
• When a detectable object is not directly in front of your vehicle • When a detectable
object is near
a wall, fence, gua rdrail, manhole
cover, vehicle, steel plate on the
road, etc.
• When a detectable object is under a structure
• When part of a detectable object
is hidden by an object, such as
large baggage, an umbrella, or
guardrail
• When multiple det ectable objects
are close together
• If the sun or other light is shining directly on a detectable object
• When a detectable object is a shade of white and looks
extremely bright
• When a detectable object appears to be nearly the same color or
brightness as its surroundings
• If a detectable object cuts or sud- denly emerges in front of your
vehicle
• When the front of your vehicle is hit by water, snow, dust, etc.
• When a very bright light ahead,
such as the sun or the headlights
of oncoming traffic, shines directly
into the front camera
• When approaching the side or front of a vehicle ahead
• If a vehicle ahead is a motorcycle
• If a vehicle ahead is narrow, such
as a personal mobility vehicle
• If a preceding vehicle has a small
rear end, such as an unloaded

●In some situations such as the fol-
lowing, sufficient braking force
may not be obtained, preventing
the system from p erforming prop-
erly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, ext remely hot, or
wet
• If the vehicle is not properly main-
tained (brakes or tires are exces-
sively worn, imprope r tire inflation
