●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 disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
• When the temperature around t he 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 vehicle, such as when driving in the dark, snow, or fog, or when bright lights are shining into the front
camera
SituationActions
When the area around a sensor is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
To clean the part of the windshield in
front of the front camera, use the wind-
shield wipers or the windshield defogger
of the air conditioning system ( P.381,
387).
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 environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditi oning system 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 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 cam-
era.
Close the hood, remove the sticker, etc.
to clear the obstruction.

2024-5. Using the driving support systems
*: If equipped
The system can detect the follow-
ing:
 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 mess age will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■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 collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.205)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing 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 sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.204)

■Limitations of the pre-collision
system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your
surroundings. Do not use the pre-collision system
instead of normal braking opera-
tions under any circumstances.
This system will not prevent colli- sions or lessen collision damage or
injury in every situation. Do not
overly rely on this system. Failure to do so may lead to an accident,
resulting in death or serious injury.
●Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effec- tiveness may change according to
various conditions, therefore the
system may not always be able to achieve the same level of perfor-
mance.
Read the following conditions care- fully. Do not overly rely on this sys-
tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P.206
• Conditions under which the system
may not operate properly:P.207
●Do not attempt to test the operation
of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard
objects imitating detectable objects,
etc.), the system may not operate properly, possibly leading to an
accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large amount of braking force will be
applied.
●If the vehicle is stopped by the operation of the pre-collision brak-
ing function, the pre-collision brak-
ing function operation will be canceled after approximately 2 sec-
onds. Depress the brake pedal as
necessary.
●The pre-collision braking function
may not operate if certain opera- tions are performed by the driver. If
the accelerator pedal is being
depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak-
ing evasive action and possibly pre- vent the pre-collision braking
function from operating.
●In some situations, while the
pre-collision braking function is
operating, operation of the function may be canceled if the accelerator
pedal is depressed strongly or the
steering wheel is turned and the system determines that the driver is
taking evasive action.
●If the brake pedal is being
depressed, the system may deter-
mine that the driver is taking eva- sive action and possibly delay the
operation timing of the pre-collision
braking function.
■When to disable the pre-colli-
sion system
In the following situations, disable the
system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing
another vehicle
●When transporting the vehicle via
truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift
with the engine running and the tires are allowed to rotate freely

2044-5. Using the driving support systems
■Enabling/disabling the pre-col-
lision system
The pre-collisio n system can be
enabled/disabled on ( P.538)
of the multi-information display.
The system is auto matically enabled
each time the engine switch is turned to
ON.
If the system is disabled, the PCS
warning light will turn on and a
message will be di splayed on the
multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on ( P.538) of
the multi-information display.
The warning timing setting is retained
when the engine switch is turned off.
However, if the pr e-collision system is
disabled and re-enabled, the operation
timing will return to the default setting
(middle).

■Operational conditions
The pre-collision system is enabled and the sy stem determines that the possibility of a frontal collision with a detected object is high.
Each function is operational at the following speed
●Pre-collision warning
●Pre-collision brake assist
●Pre-collision braking
The system may not operate in the following situations:
●If a battery terminal has been disconnected and reconnected and then the vehicle
has not been driven for a certain amount of time
●If the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning function
will be operational)
■Object detection function
The system detects objects based on their size, profile, motion, etc. However,
an object may not be detected depend-
ing on the surrounding brightness and
the motion, posture, and angle of the
detected object, preventing the system from operating properly. ( P.207)
The illustration shows an image of
detectable objects.
