■ 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 conditions are  detected, the message 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.
SituationActions
When the area around a sensor 
is covered with dirt, moisture 
(fogged up, covered with con- 
densation, ice, etc.), or other
foreign matter
To clean the part of the windshield in front
of the front camera, use the windshield 
wipers or the windshield defogger of the 
air conditioning system ( P. 519, 528).
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 environ- 
ment
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 vehi-
cle was parked, depending on its type, 
the sunlight reflected from the surface 
of the sunshade may cause the tem-
perature 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 camera.
Close the hood, remove the sticker, etc.
to clear the obstruction.

■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 colli- 
sion 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.

■Enabling/disabling the pre-collision system 
The pre-collision system can be 
enabled/disabled on  
( P. 155) of the multi-informa- 
tion display.
The system is automatically 
enabled each time the engine 
switch is turned to the “ON” 
position (vehicles without smart
entry & start system) or IGNI- 
TION ON mode (vehicles with 
smart entry & start system).
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. 155) of the multi-informa- 
tion display.
The warning timing setting is 
retained when the engine switch
is turned to the “LOCK” position 
(vehicles without smart entry & 
start system) or off (vehicles
with smart entry & start system). 
However, if the pre-collision sys- 
tem is disabled and re-enabled,
the operation timing will return to 
the default setting (middle).

This is the default setting.

• If the wheels are misaligned 
• If a wiper blade is blocking the front camera 
• The vehicle is being driven at extremely high speeds 
• When driving on a hill
• If the radar sensor or front camera is misaligned 
● In some situations such as the following, sufficient braking force may not be 
obtained, preventing the system from performing properly: 
• If the braking functions cannot operate to their full extent, such as when 
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively 
worn, improper tire inflation pressure, etc.) 
• When the vehicle is being driven on a gravel road or other slippery sur-
face 
■ If VSC is disabled 
● If VSC is disabled (P. 425), the pre-collision brake assist and pre-collision 
braking functions are also disabled. 
● The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake 
System Unavailable” will be displayed on the multi-information display. 
• If the front of the vehicle is raised or 
lowered

■Lane departure alert function 
When the system determines 
that the vehicle might depart 
from its lane or course*, a 
warning is displayed on the 
multi-information display, and a 
warning buzzer will sound to 
alert the driver.
When the warning buzzer 
sounds, check the area around 
your vehicle and carefully oper- 
ate the steering wheel to move
the vehicle back to the center of 
the lane.

■Yaw assist function 
When the system determines that the vehicle might depart from its 
lane or course*, the system provides assistance as necessary by 
applying a brake force for a short period of time to keep the vehicle 
in its lane.

the side of the road, such as
grass, soil, or a curb 
■Vehicle sway warning function 
When the vehicle is swaying 
within a lane, the warning 
buzzer will sound and a mes- 
sage will be displayed on the 
multi-information display to alert 
the driver.
