ment is required. Have the sensor
adjusted at a Toyota dealer.)
• When a large amount of snow or ice sticks to the rear bumper sur-
face around the radar sensors
• When the vehicle is driven on a snow-covered road or in an envi-
ronment in which there are no
objects around (such as in a des-
ert) for a prolonged period of time
• When the temperature around the
radar sensors increases exces-
sively due to long driving on uphill
grades in the summer, etc.
• When the temperature around the radar sensors becomes extremely
low
• When the vehicle battery voltage lowers
• When the vehicle voltage exceeds
the battery voltage rating
●The BSD/RCTA will resume oper-
ation once these conditions are
corrected, and the BSD/RCTA
OFF indicator will disappear. How-
ever, if the BSD/RCTA OFF indi- cator appears for a prolonged
period of time, have the system
inspected at a Toyota dealer as
soon as possible.
●The detectability o
f the radar sen-
sors is restricted. The BSD/RCTA
detection may be impaired and
the system may not operate prop-
erly under the following condi-
tions.

trailer with no cargo and sports
cars)
• Vehicles that are not approaching
your vehicle even though they are
in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when revers-
ing) (The system determines the
presence of approaching vehicles
based on data detected by the
radar sensors.)
• Vehicles traveling at significantly
different speeds
• Vehicles driving in parallel at almost the same speed as your
vehicle for a prolonged time
• Oncoming vehicles
• Vehicles in a lane beyond the neighboring lane
• Vehicles travelling at a signifi- cantly lower speed that you are
