WARNING
■Handling the radar sensor
One  Blind  Spot  Monitor  sensor  is  installed  inside  the  left  and  right  side  of
the  vehicle  rear  bumper  respectively.  Observe  the  following  to  ensure  the
Blind Spot Monitor can function correctly.
If  the  warning  message  does  not  disappear,  have  the  vehicle  inspected
by your Toyota dealer.
● Do  not  subject  a  sensor  or  its  surrounding  area  on  the  rear  bum per  to  a
strong impact.
If a sensor is moved even slightly off position, the system may  malfunction
and vehicles may not be detected correctly.
In  the  following  situations,  have  your  vehicle  inspected  by  your  Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If  the  surrounding  area  of  a  sensor  is  scratched  or  dented,  or   part  of
them has become disconnected.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surround ing area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensor and its surrounding
area on the bumper clean at all times.
If  a  sensor  or  its  surrounding  area  on
the  rear  bumper  is  dirty  or  covered
with snow, the Blind Spot Monitor may
not  operate  and  a  warning  message
( P. 270) will be displayed.
In  this  situation,  clear  off  the  dirt  or
snow  and  drive  the  vehicle  with  the
operation  conditions  of  the  BSM  func-
tion  ( P.  275)  satisfied  for  approxi-

The BSM function uses radar sensors to detect the following vehicles
traveling  in  adjacent  lanes  and  ad vises  the  driver  of  the  presence  of
such vehicles via the indicators on the out side rear view mirrors.
Vehicles that are traveling in  areas that are not visible using  the out-
side rear view mirrors (the blind spots)
Vehicles that are approaching rapidly from behind in areas that  are
not visible using the outside re ar view mirrors (the blind spots)

The areas that vehicles can be  detected in are outlined below.
The range of each detection area is: Approximately  1.6  ft.  (0.5  m)  to  11.5  ft.  (3.5  m)  from  either  s ide  of
the vehicle
*
*
: The area between the side of the vehicle and 1.6 ft. (0.5 m) f rom the side
of the vehicle cannot be detected.
Approximately 3.3 ft. (1 m) f orward of the rear bumper
Approximately 9.8 ft. (3  m) from the rear bumper
Approximately 9.8 ft. (3 m) to 19 7 ft. (60 m) from the rear bumper
*
*
: The greater the difference in speed between your vehicle and t he detected
vehicle  is,  the  farther  away  the  vehicle  will  be  detected,  causing  the  out-
side rear view mirror indicator to illuminate or flash.

WARNING
■Cautions regarding the use of the system
The  driver  is  solely  responsible  for  safe  driving. Always  drive  safely,  taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function whi ch alerts the
driver  that  a  vehicle  is  present  in  the  blind  spot.  Do  not  over ly  rely  on  the
Blind Spot Monitor function. The function cannot judge if it is  safe to change
lanes, therefore over reliance could cause an accident resultin g in death or
serious injury.
According  to  conditions,  the  system  may  not  function  correctly.  Therefore
the driver’s own visual confirmation of safety is necessary.
