■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.
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.324).
When the temperature around the
front camera is out side 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 r eflected from the
surface of the sunshade may cause
the temperature of the front camera
to become exce ssively 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 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.
When “Pre-Collisi on 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.

the engine is stopped by the Stop &
Start system and the shift lever is in
D, a buzzer will soun d and the Stop
& Start system indicator will flash. To
stop the buzzer, c lose the driver’s
door.
■The Stop & Start system protec-
tion function
●When the volume of the audio
system is excessively high, sound
output from the audio system may
suddenly be cut off in order to
reduce battery consumption. To
prevent the audio system from
being cut off, keep the volume of
audio system at a moderate level.
If the audio system has been cut
off, turn the engine switch off, wait
for 3 seconds or more and then
turn it to ACC or ON to re-enable
the audio system.
●The audio system may not be acti-
vated if the battery terminals are
disconnected and then recon-
nected. If this o ccurs, turn the
engine switch off and then repeat
the following oper ation twice to
activate the audio system nor-
mally.
• Turn the engine switch to ON and then to OFF.

2784-5. Using the driving support systems
• 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.
■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When an object that cannot be
detected is between the vehicle
and a detected object.
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle carrier, or snow plow.
●If the front of the v ehicle is raised

2884-5. Using the driving support systems
●If the front of the vehicle is raised
or lowered due to the carried load
●When turning while backing up
●When a vehicle turns into the
detection area
■Situations in which the system
may operate even if there is no
possibility of a collision
Instances of the RCTA function
unnecessary detec ting a vehicle
and/or object may increase in the
following situations:
●When the parking space faces a
street and vehicles are being
driven on the street
●When the distanc e between your
vehicle and metal objects, such as
a guardrail, wall, sign, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
●When a vehicle passes by the
side of your vehicle
●When a detected vehicle turns
while approaching the vehicle
●When there are spinning objects
near your vehicle such as the fan
of an air conditioning unit
●When water is splashed or
sprayed toward the rear bumper,
such as from a sprinkler
●Moving objects (f lags, exhaust
fumes, large rain droplets or
snowflakes, rain water on the road
surface, etc.)
●When the distance between your
vehicle and a guardrail, wall, etc.,
that enters the detection area is
short
●Gratings and gutters
