Tire pressure monitoring
system (TPMS) (if equipped)
Low tire pressure warning light
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise an accident involving
serious vehicle damage and ser-
ious personal injury could occur.
(1) Keep driving straight ahead while gradually reducing
speed.
(2) Slowly pull off the road to a safe place.
(3) Check the pressure for all four tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver ’s side.
Even when the vehicle is driven a very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on
the tire placard. Refer to “Tires
and wheels ”F11-25. The tire
pressure monitoring system
does not function when the ve- hicle is stationary. After adjusting
the tire pressures, increase the
vehicle speed to at least 20 mph
(32 km/h) to start the TPMS
rechecking of the tire inflation
pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should
turn off a few minutes later.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as
possible.
. When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute.
This indicates the TPMS is un-
able to monitor all four road
wheels. Contact your SUBARU
dealer as soon as possible for
tire and sensor replacement and/
or system resetting.
. When a tire is repaired with liquid

sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off. Do not inject any tire
liquid or aerosol tire sealant into
the tires, as this may cause a
malfunction of the tire pressure
sensors. If the light illuminates
steadily after blinking for ap-
proximately one minute,
promptly contact a SUBARU
dealer to have the system in-
spected.CAUTION
Do not place metal film or any metal
parts under the driver’s seat. This
may cause poor reception of the
signals from the tire pressure sen-
sors, and the tire pressure monitor-
ing system will not function prop-
erly.

Parking your vehicle
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to them.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.

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 of BSD/RCTA are the
systems that detect objects and vehicles
to the rear and draw attention to the driver
when changing a lane or when driving in
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 indicator
light may be delayed or it may notoperate 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
following features.
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 ”F 7-61. !
Blind Spot Detection (BSD)
1) Operating range
The system notifies the driver of the
presence of vehicles in its blind spot.
.If the system detects a vehicle in its
blind spot, it warns the driver 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 illuminat-
ing, the system warns the driver of
dangers by flashing the BSD/RCTA ap-
proach indicator light.
7-54

!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 ap-
proaching at a high speed in the neighbor-
ing lanes, it warns the driver of dangers by
illuminating the BSD/RCTA approach in-
dicator 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 illuminat-
ing, the system warns the driver of
dangers by flashing the BSD/RCTA ap-
proach 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.
. An icon appears on the rear view
camera screen (if equipped) !
Limitations of the detectability of
RCTA
Since the detectability of RCTA is limited,
the RCTA may not operate properly in
parking areas in which the parking spaces
are drawn diagonally to the driving lanes.
Example 1
1) The detection range of the radar sensors
2) Area out of detection range of the radar sensors
A) Vehicle that may not be detected
B) Parked vehicle
WARNING
An approaching vehicle (A) may not
be detected because the detection
range is limited by the parked
vehicle (B). Always be sure to check

The BSD/RCTA will resume operation
once these conditions are corrected,
and the BSD/RCTA warning indicator
will disappear. However, if the BSD/
RCTA warning indicator appears for a
prolonged period of 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
the rear bumper
– During adverse weather condi-
tions such as rain, snow or fog
– When driving on wet roads such
as snow-covered roads and
through puddles
. The radar sensors may not detect or
may have difficulty detecting the fol-
lowing vehicles and objects.
–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
with lower body height such as a
trailer with no cargo and sports
cars)
– 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.& BSD/RCTA approach indica-
