■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in the sys- tem.
●In the following situations, perform the actions specified in t he table. When the nor- mal operating conditions are detected, the message will disappe ar and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota
authorized repairer, or any reliable repairer.
SituationActions
When the area around a camera is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. ( P.290).
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 conditioning 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.
When “Pre-Collision System Radar In
Self Calibration Unavailable See
Owner’s Manual” is displayed.
Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

●In the following situations, if the situation has changed (or the vehicle has been
driven for some time) and the normal operating conditions are d etected, the mes- sage will disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota
authorized repairer, or any reliable repairer.
• 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 ve hicle, such as when driving in the dark, snow, or fog, or when bright lights are sh ining 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 recognized. In that case, “Pre-Colli-
sion System Unavailable See Owner’s Manual” is displayed.

*: If equipped
The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
 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.
■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.
■Emergency steering assist
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.209)
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 he lp 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 warn-
ing timing can be changed.

steered into within its lane, and the
driver has begun evasive maneuver
or steering, emergency steering
assist will assist the steering move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention. During operation, the indi-
cator will illuminate in green.
■Intersection right/left turn
assistance
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.
 When you turn right/left at an
intersection and cross the path of
an oncoming vehicle
 When you turn right/left, pedes-
trian is detected in the forward
direction and estimated to enter
your vehicle’s path (bicyclists are
not detected.)
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your sur-
roundings. 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. 2 1 5

■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 hybrid system on and the tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tes-
ter, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle has been in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed
●When a compact spare tire or an emergency tire puncture repair kit is
used
●If equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is temporarily installed

■Operational conditions for each pre-collision function
The pre-collision system is enabled and the system determines t hat the possibility of
a frontal collision with a detected object is high. The system may not operate in the following situations:
• If a 12-volt battery terminal has been disconnected and reconn ected 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-collis ion warning function
will be operational)
