7-19. BSD/RCTA (if equipped)

The BSD/RCTA consists of rear corner

radars with Blind Spot Detection and Rear

Cross Traffic Alert.

These functions enable the system to

detect objects or vehicles to the rear,

drawing attention to the driver when

changing a lane or when driving in reverse.

When using the Hill start assist system, a

braking effect may be felt even after the

brake pedal has been released.

WARNING

The driver is responsible for driving

safely. Always be sure to check the

surroundings when changing lanes

or reversing the vehicle.

CAUTION

The braking power of the Hill start

assist system may not be sufficient

when strong braking power is

needed (e.g., when towing a trailer).

The system is designed to assist the

driver to change lanes or reverse

safely by monitoring the rear and

side areas of the vehicle. However,

you cannot rely on this system alone

in assuring the safety during a lane

change or reversing. Overconfi-

dence in this system could result in

an accident and lead to serious

injury or death. Since the system

operation has various limitations,

the flashing or illumination of the

BSD/RCTA approach indicator light

may be delayed or the warning

buzzer may be delayed or inopera-

NOTE

A slight jolt may be felt when the

vehicle begins to move forward after

being reversed.

tive, even if there is a vehicle travel-

ing in a neighboring lane or ap-

proaching your vehicle from either

side.

! Blind Spot Detection (BSD)

The driver is responsible for paying

attention to the rear and side areas

of the vehicle.

& System features

BSD/RCTA consists of the following func-

tions.

.

To detect a vehicle in a blind spot on an

adjacent lane or a vehicle approaching

at high speeds (Blind Spot Detection).

To detect a vehicle approaching from

the right or left while reversing the

vehicle (Rear Cross Traffic Alert).

If the driver operates the turn signal

lever in the direction which the BSD/

nating, the corresponding BSD/RCTA

approach indicator light will flash.

Operating range

The system warns the driver of dangers as

If the system detects a vehicle in the

blind spot, the BSD/RCTA approach

indicator light(s) on the outside mirror

(s) will illuminate.

The system uses radar sensors for the

above functions.

NOTE

The BSD/RCTA radar sensor has been

certified by the radio wave related laws

of the U.S. and Canada. When driving in

other countries, certification of the

country where the vehicle is driven

must be obtained. For certification in

the U.S. and Canada, refer to “Certifica-

tion for the BSD/RCTA” �P366.

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

vehicle when moving backward.

If the system detects a vehicle ap-

proaching at a high speed in the

neighboring lanes, the BSD/RCTA ap-

& System operation

– When a malfunction occurs in the

system, including the BSD/RCTA

approach indicator light.

In the following cases, the BSD/

RCTA will temporarily stop operat-

ing (or may stop operating) and the

BSD/RCTA OFF indicator light will

appear.

! Operating conditions

The BSD/RCTA will operate when all of the

following conditions are met.

.

The ignition switch is in the “ON”

position.

.

The BSD/RCTA warning light and BSD/

RCTA OFF indicator light are turned off.

– When the radar sensor becomes

significantly misaligned (If the

orientation 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

surface around the radar sen-

sors.

– When the vehicle is driven on a

snow-covered road or in an en-

vironment in which there are no

objects around (such as in a

desert) for a long time.

.

The EyeSight warning indicator is off.

The vehicle is driven at speeds above 7

mph (12 km/h) (except when rever-

sing).

The select lever is in the “R” position

(when reversing).

The vehicle speed is below 6 mph (10

km/h) even when the BSD/RCTA OFF

indicator light remains off (except when

reversing).

NOTE

The system may detect that a vehicle

(C) is passing in front of your vehicle.

Always be sure to check the surround-

ings when reversing the vehicle.

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 8-inch audio/navigation

system is performing a software

may not be displayed on the audio/

navigation screen until the update is

complete.

– When an overvoltage occurs in

the vehicle battery.

– Small motorcycles, bicycles, pe-

destrians, stationary objects on

the road or road side, etc.

– Vehicles with body shapes that

the radar may not reflect (vehi-

cles with a low body height such

as sports cars or a trailer with no

cargo).

– 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

reversing). (The system deter-

mines the presence of approach-

ing vehicles based on data de-

tected by the radar sensors.)

– Vehicles traveling at significantly

different speeds

– Vehicles driving parallel to your

vehicle at almost the same speed

for a prolonged time

– Oncoming vehicles

– Vehicles in a lane beyond the

neighboring lane

When the above conditions are cor-

rected, the BSD/RCTA will resume

operation and the BSD/RCTA OFF

indicator light will disappear. How-

ever, if the BSD/RCTA OFF indicator

light has appeared for a prolonged

time, have the system inspected at a

SUBARU dealer as soon as possible.

& BSD/RCTA approach indica-

tor light/warning buzzer

When the BSD/RCTA is active, the BSD/

RCTA approach indicator light will operate

to alert the driver when there are vehicles

in the neighboring lanes. When reversing

the vehicle, the BSD/RCTA approach

indicator light and warning buzzer will

operate to alert the driver that a vehicle is

approaching from the left or right side.

.

The detectability of the radar sen-

sors is restricted. The BSD/RCTA

detection may be impaired 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 condi-

tions such as rain, snow or fog

– When driving on wet roads such

as snow-covered roads or

through puddles
