■Lane Change Assist (LCA)
The system notifies the driver of
vehicles approaching at a high
speed in the neighboring lanes.
 If the system detects a vehicle
approaching at a high speed in
the neighboring lanes, it warns
the driver of dan gers by illumi-
nating the BSD/RCTA approach
indicator(s) on the outside mir-
ror(s).
 If the driver operates the turn sig-
nal lever in the direction where
the BSD/RCTA approach indica-
tor is illuminati ng, the system
warns the driver of dangers by
flashing the BSD/RCTA
approach indicator.
Operating range
■Rear Cross Traffic Alert
(RCTA)
The system notifies the driver of
another vehicle approaching from
either side when driving in reverse.
This feature helps the driver check
the rear and side areas of the vehi-
cle when moving backward.
If the system detects a vehicle
approaching from either side while
moving backward, it warns the
driver of dangers in the following
way.
 The BSD/RCTA approach indica-
tor(s) on the outside mirror(s)
flashes.
 A warning buzzer sounds.
 An icon appears on the multime-
dia system screen.

• When the radar sensor becomes sig- nificantly misaligned (If the orientation
of the radar sensor is shifted for any
reason, readjustment is required. Have the sensor adjusted at any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.)
• When a large amount of snow or ice
sticks to the rear bumper surface around the radar sensors
• When the vehicle is driven on a
snow-covered road or in an environ- ment in which there are no objects
around (such as in a desert) for a pro-
longed period of time • When the temperature around the
radar sensors increases excessively
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 low-
ers
• When the vehicle voltage exceeds the battery voltage rating
●The BSD/RCTA will resume operation once these conditions are corrected,
and the BSD/RCTA OFF indicator will
disappear. However, if the BSD/RCTA OFF indicator appears for a prolonged
period of time, have the system
inspected at any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer as soon as
possible.
●The detectability of the radar sensors
is restricted. The BSD/RCTA detec- tion may be impair ed and the system
may not operate properly under the
following conditions.
• When the rear bumper around the radar sensors is distorted
• When ice, snow or mud adheres to
the rear bumper surface around the radar sensors
• When stickers, etc. are affixed on the
areas of the radar sensors on the rear bumper
• During adverse weather conditions
such as rain, snow or fog
• When driving on wet roads such as
snow-covered roads and through pud- dles
●The radar sensors may not detect or may have difficulty detecting the fol-
lowing vehicles and objects.
• Small motorcycles, bicycles, pedestri- ans, stationary objects on the road or
road side, etc.
• Vehicles with body shapes that the radar may not reflect (vehicles with
lower body height such as a 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 neigh- boring lane to the rear or beside your
vehicle when revers ing) (The system
determines the presence of approach- ing vehicles based on data detected
by the radar sensors.)
• Vehicles traveling at significantly dif- ferent 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 neigh- boring lane
• Vehicles travelling at a significantly
lower speed that you are trying to overtake
●On a road with extremely narrow lanes, the system may detect vehicles
driving in a lane next to the neighbor-
ing lane.
While the BSD/RCTA is active, the
following item(s) will operate to
alert the driver:
 The BSD/RCTA approach indica-
tor (when there are vehicles in

between your lane and the neighbor-
ing lane
• Immediately after the BSD/RCTA is
activated by touching “BSD/RCTA”
• Immediately after the shift lever is
shifted to R
• When extremely heavy cargo is
loaded in the trunk
 During reversing, operation of
the BSD/RCTA approach indica-
tor and the warning buzzer may
be delayed or the system may
fail to issue these warnings
under the following conditions.
• When backing out of an angled park-
ing space
• When a large-sized vehicle is parked
next to your vehicle (That vehicle pre-
vents the propagation of radar
waves.)
• When reversing on sloped roads
• When reversing at a high speed
 The BSD/RCTA approach indica-
tor may illuminate when driving
close to solid objects on the road
or road side (such as guardrails,
tunnels and sidewalls).
 When turning at an intersection
in urban areas, or a multilane
intersection, the BSD/RCTA
approach indicator may flash.
 If a building or a wall exists in the
reversing direction, the
BSD/RCTA approach indicator
may flash and the warning
buzzer may sound.
 In the following cases, the sys-
tem may detect a vehicle driving
two lanes away from your vehi-
cle.
• When your vehicle drives on the near
side of its lane from the correspond-
ing vehicle
• When the vehicle driving two lanes
away drives on the near side of its
lane from your vehicle
■System temporary stops
