■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in 
the system.
●In the following situations, perform the  actions specified in the table. When 
the normal operating cond itions are detected, the message will disappear 
and the system will be come operational.
If the message does not disappear, 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 sy stem 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.411, 419).
When the temperature around the 
front camera is outside 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  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 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-Collision System 
Unavailable” is displayed.
Check whether there is attached 
materials on the radar sensor and 
radar sensor cover, and if there is, 
remove it.

If the message does not disappear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-tional 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
• Depending on the conditions in the vicinity of the vehicle, the radar may  judge the surrounding environment can not be properly recognized. In that 
case, “Pre-Collision System Unavailable” is displayed.

The system can detect the fol-
lowing:
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 colli-
sion is extremely high, the 
brakes are automatically applied 
to help avoid the collision or 
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system 
uses a radar sensor and 
front camera to detect 
objects ( P.198) 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 col-
lision.
The pre-collision system 
can be disabled/enabled 
and the warning timing can 
be changed. ( P.197)

WARNING
■Limitations of the pre-colli-
sion system
●The driver is solely responsible 
for safe driving. Always drive 
safely, taking care to observe 
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking 
operations under any circum-
stances. This system will not 
prevent collisions or lessen col-
lision damage or injury in every 
situation. Do not overly rely on 
this system. Failure to do so 
may lead to an accident, result-
ing in death or serious injury.
●Although this system is 
designed to help avoid a colli-
sion or help reduce the impact 
of the collision, its effectiveness 
may change according to vari-
ous conditions, therefore the 
system may not always be able 
to achieve the same level of 
performance.
Read the following conditions 
carefully. Do not overly rely on 
this system and always drive 
carefully.
• Conditions under which the sys- tem may operate even if there is 
no possibility of a collision: 
P. 1 9 9
• Conditions under which the sys- tem may not operate properly: 
P. 2 0 0
●Do not attempt to test the oper-
ation of the pre-collision system 
yourself.
Depending on the objects used 
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system 
may not operate properly, possi-
bly leading to an accident.
■Pre-collision braking
●When the pre-co llision 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 
braking function, the pre-colli-
sion braking function operation 
will be canceled after approxi-
mately 2 seconds. Depress the 
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain 
operations 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 taking evasive 
action and possibly prevent the 
pre-collision braking function 
from operating.
●In some situations, while the 
pre-collision braking function is 
operating, operation of the func-
tion may be canceled if the 
accelerator pedal is depressed 
strongly or the steering wheel is 
turned and the system deter-
mines that the driver is taking 
evasive action.
●If the brake pedal is being 
depressed, the system may 
determine that the driver is tak-
ing evasive 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 
properly, possibly leading to an 
accident resulting in death or seri-
ous injury:
●When the vehicle is being towed

■Enabling/disabling the 
pre-collision system
The pre-collision system can be 
enabled/disabled on   
( P.563) of the multi-informa-
tion display.
The system is automatically 
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 displayed 
on the multi-information display.
■Changing the pre-collision 
warning timing
The pre-collision warning timing 
can be changed on   
( P.563) of the multi-informa-
tion display.
The warning timing setting is 
retained when the engine switch is 
turned off. However, if the pre-colli-
sion system is disabled and 
re-enabled, the operation timing will 
return to the default setting (mid-
dle).

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 depending on the sur-
rounding brightness and the motion, 
posture, and angle of the detected 
object, preventing the system from 
operating properly. ( P.200)
The illustration shows an image of 
detectable objects.
■Cancelation of the pre-collision 
braking
If either of the following occur while 
the pre-collision braking function is 
operating, it will be canceled:
●The accelerator pedal is 
depressed strongly.
●The steering wheel is turned 
sharply or abruptly.
■Conditions under which the 
system may operate even if 
there is no possibility of a colli-
sion
●In some situations such as the fol-
lowing, the system may determine 
that there is a possibility of a fron-
tal collision and operate.
• When passing a detectable object,  etc.
• When changing lanes while over-
taking a detectable object, etc.
• When approaching a detectable  object in an adjace nt lane or on 
the roadside, such as when 
changing the course of travel or 
driving on a winding road

■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
