Starting and operating/Tire pressure monitoring system (TPMS) (U.S.–spec. models)
Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)
Low tire pressure warning light (type A)
Low tire pressure warning light (type B)
The tire pressure monitoring system pro-
vides the driver with a warning message.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 25 mph (40 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 location.
(3) Check the pressure for all four tires and adjust the pressure
to the COLD tire pressure
shown on the tire placard.
The tire placard is located 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” F11-23. 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 25 mph
(40 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-
7-46

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.
. 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 approximately one
minute, promptly contact a
SUBARU dealer to have the sys-
tem inspected.
CAUTION
. Do not place metal film or any
metal parts in the cargo area.
This may cause poor reception of
the signals from the tire pressure
sensors, and the tire pressure
monitoring system will not func-
tion properly.

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.
7-58

!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.
1) The detection range of the radar sensors
A) Vehicle that may be detected
WARNING
In parking areas in which parking
lots are located diagonally to driving
lanes as indicated in the illustration
above, the system may detect a
vehicle (A) that is coming across
the front of your vehicle in some
cases. Always be sure to check the
surroundings with your eyes when
reversing the vehicle, because the
detectability of RCTA is limited.

B) Vehicle that may not be detected
WARNING
The approaching vehicle (B) may
not be detected because the vehicle
reversing is blocked by a parked
vehicle. Always be sure to check the
surroundings with your eyes when
