Starting and operating/BSD/RCTA
BSD/RCTA (if equipped)
The BSD/RCTA consists of rear radar 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
changingalaneorwhendrivingin
reverse.
WARNING
The driver is responsible for driving
safely. Always be sure to check the
surroundings with your eyes when
changing lanes or reversing the
vehicle.
The system is designed to assist the
driver by monitoring the rear and
side areas of the vehicle during a
lane change or reversing. However,
you cannot rely on this system
alone in assuring the safety during
a lane change or reversing. Over-
confidence in this system could
result in an accident and lead to
serious injury or death. Since the
system operation has various limita-
tions, the flashing or illumination of
the BSD/RCTA approach indicatorlight may be delayed or it may not
operate at all even when a vehicle is
present in a neighboring lane or
approaching from either side.
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 speed while driving the vehicle (Blind
Spot Detection)
. To detect a vehicle approaching from
the right or left while reversing the vehicle
(Rear Cross Traffic Alert)
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. When driving in other
countries, certification of the country
where the vehicle is driven must be
obtained. For certification in the U.S.,
refer to “Certification for the BSD/
RCTA ”F 7-65. !
Blind Spot Detection (BSD)
1) Operating range
The system notifies the driver of vehicles
existing in the blind area. If the system
detects a vehicle existing in the blind area,
it warns the driver of dangers by illuminat-
ing the BSD/RCTA approach indicator
light(s) on the outside mirror(s). If the
driver operates the turn signal lever in the
direction where the BSD/RCTA approach
indicator light is illuminating, the system
warns the driver of dangers by flashing the
BSD/RCTA approach indicator light.

!Lane Change Assist (LCA)
1) Operating range
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 dangers by illuminating the BSD/RCTA
approach indicator light(s) on the outside
mirror(s). If the driver operates the turn
signal lever in the direction where the
BSD/RCTA approach indicator light is
illuminating, the system warns the driver
of dangers by flashing the BSD/RCTA
approach indicator light. !
Rear Cross Traffic Alert (RCTA)
1) Operating range
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 approach-
ing from either side while moving back-
ward, it warns the driver of dangers in the
following way.
.The BSD/RCTA approach indicator
light(s) on the outside mirror(s) flashes.
. A warning buzzer sounds.

Driving tips/Loading your vehicle
NOTE
When tire chains cannot be used, use
of another type of traction device (such
as spring chains) may be acceptable if
use on your vehicle is recommended
by the device manufacturer, taking into
account tire size and road conditions.
Follow the device manufacturer’s in-
structions, especially regarding max-
imum vehicle speed.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and
use it on the front wheels only. Always
use the utmost care when driving with
a traction device. Overconfidence be-
cause you are using a traction device
could easily lead to a serious accident.& Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between
“1”/“D ”and “R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than in 1st (MT models and CVT
models with manual mode).
If your vehicle is a CVT model with manual
mode, for information about holding the
transmission in the 2nd position, refer to
“Selection of manual mode ”F 7-27.
Loading your vehicle
WARNING
. Never allow passengers to ride
on a folded rear seatback or in
the cargo area. Doing so may
result in serious injury.
. Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as
possible.

1) Hitch ball installation point
2) Hooks for safety chains
5. Use only a hitch ball that is appropriate
for the ball mount and your trailer. The
hitch ball must be securely installed on the
ball mount.
6. Connect your trailer to the hitch ball.
7. Connect the trailer and the hitch with
safety chains that will hold the trailer’s maximum gross weight. The chains
should cross under the trailer tongue to
prevent the tongue from dropping onto the
ground in case it should disconnect from
the hitch ball. Allow sufficient slack in the
chains taking tight turn situations into
account; however, be careful not to let
them drag on the ground.
WARNING
Do not connect safety chains to any
part of the vehicle other than the
safety chain hooks.

8. Connect the hitch electrical wire har-
ness
’s black four-pin electrical wire con-
nector to the towing trailer ’s wire harness. 9. Confirm proper function of the hitch
electrical wire harness by individually
activating the brake, stop and turn signal
lights on the trailer.
NOTE
Always disconnect the trailer electrical
wire harness before launching or re-
trieving a watercraft.

the left side trailer tongue. Pass the chains
crossing each other under the trailer
tongue to prevent the trailer from dropping
onto the ground in case the trailer tongue
should disconnect from the hitch ball.
Allow sufficient slack in the chains taking
tight turn situations into account; however,
be careful not to let them drag on the
ground.
!Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors
provide a good rearward field of view
without significant blind spots. If significant
blind spots occur with the vehicle’ s stan-
dard side mirrors, use towing mirrors that
conform with Federal, state/province and/
or other applicable regulations. !
Trailer lights
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’ s electrical
system and cause a malfunction of
your vehicle ’s lighting system.
Connection of trailer lights to your vehi-
cle ’s electrical system requires modifica-
tions to the vehicle ’s lighting circuit to
increase its capacity and accommodate
wiring changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals and the brake
lights each time you connect a trailer to
your vehicle.
! Tires
WARNING
Never tow a trailer when the tem-
porary spare tire is used. The tem-
porary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated. Refer to
“Tires”F 12-
10.
Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer ’s
specifications. Also check federal, state,
province and/or other applicable regula-
tions.
In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service representative or profes-
sional to repair the flat tire.
If you carry a regular size spare tire in your
vehicle or trailer as a precaution against
getting a flat tire, be sure that the spare
tire is firmly secured.
& Trailer towing tips
CAUTION
. For models equipped with the
BSD (Blind Spot Detection) and
RCTA (Rear Cross Traffic Alert)
driving support systems, when
towing a trailer, press the BSD/
RCTA OFF switch to deactivate
the system. The system may not
operate properly due to the
blocked radar waves. For details
