■ Situations in which the system may not operate properly 
● In some situations such as the following, a vehicle may not be detected by 
the radar sensor and camera sensor,  preventing the system from operating 
properly: 
• If an oncoming vehicle is approaching your vehicle 
• If a vehicle ahead is a motorcycle or bicycle
• When approaching the side or front of a vehicle 
• If a preceding vehicle has a small rear end, such as an unloaded truck 
• If a vehicle ahead is carrying a load which protrudes past its rear bumper 
• If a vehicle ahead is irregularly shaped, such as a tractor or side car 
• If the sun or other light is shining directly on a vehicle ahead 
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving, 
acceleration or deceleration) 
• When suddenly cutting behind a preceding vehicle 
• If a preceding vehicle has a low rear 
end, such as a low bed trailer 
• If a vehicle ahead has extremely high 
ground clearance 
• When a vehicle ahead is not directly 
in front of your vehicle

traffic, shines directly into the camera sensor 
• When the surrounding area is dim, such as at dawn or dusk, or while at 
night or in a tunnel
• After the engine has started the vehicle has not been driven for a certain 
amount of time 
• While making a left/right turn and for a few seconds after making a left/
right turn

■ If the PCS warning light flashes or illuminates, and a warning message is 
displayed on the multi-information display 
The pre-collision system may be tem porarily unavailable or there may be a 
malfunction in the system. 
● In the following situations, the warning light will turn off, the message will 
disappear and the system will beco me operational when normal operating 
conditions return: 
• When the radar sensor or camera s ensor or the area around either sen- 
sor is hot, such as in the sun

sor is cold, such as in an extremely cold environment 
• When the radar sensor or front grille  emblem is dirty or covered with 
snow, etc. 
• When the part of the windshield in front of the camera sensor is fogged 
up or covered with condensation or ice 
(Defogging the windshield:  P. 562, 569) 
• If the camera sensor is obstructed, such as when the hood is open or a 
sticker is attached to the windshield near the camera sensor 
● If the PCS warning light continues to flash or illuminate, or the warning mes- 
sage does not disappear, the system may be malfunctioning. Have the vehi- 
cle inspected by any authorized Toyota retailer or Toyota authorized 
repairer, or any reliable repairer immediately.
