■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also  be  occasions  when  the  sensor  cannot  detect  pedestrians,  animals,
bicycles, motorcycles, trees, or snowdrifts. 
■Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If  a  vehicle  suddenly  moves  in  front  of  your  vehicle,  such  as  at  an  inter-
section
●If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■When  there  is  a  malfunction  in  the  system,  or  if  the  system  is  tempo-
rarily unusable
Warning lights and/or warning messages will turn on or flash. ( oP.   5 4 0 ,   5 5 3 )

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When  water  or  snow  thrown  up  by  the  surrounding  vehicles  hinders  the
functioning of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
●Ve h i c l e s   t h a t   c u t   i n   s u d d e n l y

●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
●Keep the sensor and grille cover clean at all times.
Clean  the  sensor  and  grille  cover  with  a  soft  cloth  so  you  do  not  mark  or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If  the  sensor  moves  even  slightly  off  position,  the  system  may  become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong  impact,  always  have  the  area  inspected  and  adjusted  by  your
To y o t a   d e a l e r .
●Do not disassemble the sensor.
●Do  not  attach  accessories  or  stickers  to  the  sensor,  grille  cover  or  sur-
rounding area.
●Do not modify or paint the sensor and grille cover.

*1:Open door warning buzzer:
The  open  door  warning  buzzer  sounds  to  alert  one  or  more  of  the  doors  is
not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).
*2:Seat belt warning buzzer:
The  driver’s  and  front  passenger’s  seat  belts  reminder  sounds  to  alert  the
driver  and  front  passenger  that  his  or  her  seat  belt  is  not  fastened.  The
buzzer sounds intermittently for 10 seconds after the vehicle has reached a
speed of at least 12 mph (20 km/h). Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone for 20 more seconds.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact
sensors,  side  impact  sensors  (front  door),  side  impact  sensors  (front),  side
impact sensors (rear), driver’s seat position sensor, driver’s seat belt buckle
switch,  front  passenger  occupant  classification  system  (ECU  and  sensors),
“AIR  BAG  ON”  indicator  light,  “AIR  BAG  OFF”  indicator  light,  front  passen-
ger’s  seat  belt  buckle  switch,  seat  belt  pretensioner  assemblies,  airbags,
interconnecting wiring and power sources. ( oP.   1 8 7 )
■Front  passenger  occupant  classification  system  (ECU  and  sensors),
seat belt reminder and warning buzzer
●If  luggage  is  placed  on  the  front  passenger  seat,  the  front  passenger
occupant classification system (ECU and sensors) may cause the warn-
ing light to flash and the warning buzzer to sound even if a passenger is
not sitting in the seat.
●If a cushion is placed on the seat, the front passenger occupant classifi-
cation  system  (ECU  and  sensors)  may  not  detect  a  passenger,  and  the
warning light may not operate properly.

Warning messageDetailsCorrection 
procedure
(If equipped)
•Indicates that the pre-collision 
system is not currently func-
tional because the grille or the 
sensor is dirty.
•This message also appears 
when the pre-collision system 
is not functional due to over-
heating.
•Check the grille 
and the sensor and 
clean them if they 
are dirty. 
•In case of over-
heating, the system 
will become func-
tional once the sys-
tem cools down.
(Flashes)
(If equipped)
Indicates that the radar cruise 
control sensor is dirty or cov-
ered with ice.
Clean the sensor.
(Flashes)
(If equipped)
Indicates that the radar cruise 
control system is unable to 
judge vehicle-to-vehicle dis-
tance.
If the windshield 
wipers are on, turn 
them off or set 
them to either the 
intermittent or the 
slow mode.
