. In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA warning indicator will appear.
When the radar sensor becomes
significantly misaligned (If the or-
ientation of the radar sensor is
shifted for any reason, readjust-
ment is required. Have the sensor
adjusted at a SUBARU 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 envir-
onment in which there are no
objects around (such as in a desert)
for a long time
When the temperature around
the radar sensors increased exces-
sively due to long driving on uphill
grades in summer, etc.
When the temperature around
the radar sensors becomes extre-
mely low
When the vehicle battery voltage
lowers
When the vehicle battery be-
comes overvoltage
When the above conditions are cor-
rected, the BSD/RCTA will resume
Starting and operating/BSD/RCTA (5 door models
operation and the BSD/RCTA warning
indicator will disappear. However, if the
BSD/RCTA warning indicator has ap-
peared for a prolonged time, have the
system inspected at a SUBARU dealer
as soon as possible.
. The detectability of the radar sen-
sors is restricted. The BSD/RCTA de-
tection may be impaired and the sys-
tem 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

Small motorcycles, bicycles, pe-
destrians, stationary objects on the
road or road side, etc.
Vehicles with body shapes that
the radar may not reflect (vehicles
if equipped)
with a low body height such as
sports cars or a trailer with no
cargo)
Vehicles that are not approach-
ing your vehicle even though they
are in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when rever-
sing) (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
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.
