Front seats
WARNING
. Never adjust the seat while driv-
ing to avoid the possibility of
loss of vehicle control and of
personal injury.
. Before adjusting the seat, make
sure the hands and feet of rear
seat passengers and cargo are
clear of the adjusting mechan-
ism.
. After adjusting the seat, push it
slightly to make sure it is se-
curely locked. If the seat is not
securely locked, it may move or
the seatbelt may not operate
properly.
. Do not put objects under the front
seats. They may interfere with
front seat locking and cause an
accident.
. Seatbelts provide maximum re-
straint when the occupant sits
well back and upright in the seat.
To reduce the risk of sliding
under the seatbelt in a collision,
the front seatbacks should be
always used in the upright posi-
tion while the vehicle is running. If the front seatbacks are not
used in the upright position in a
collision, the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen will
increase, and both can result in
serious internal injury or death.
. The SRS airbags deploy with
considerable speed and force.
Occupants who are out of proper
position when the SRS airbag
deploys could suffer very serious
injuries. Because the SRS airbag
needs enough space for deploy-
ment, the driver should always
sit upright and well back in the
seat as far from the steering
wheel as practical while still
maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.
WARNING
Put children aged 12 and under in
the rear seat properly restrained at
all times. The SRS airbag deploys
with considerable speed and force
and can injure or even kill children,
especially if they are 12 years of age
and under and are not restrained or
improperly restrained. Because chil-
dren are lighter and weaker than
adults, their risk of being injured
from deployment is greater. For that
reason, we strongly recommend
that ALL children (including those
in child seats and those that have
outgrown child restraint devices) sit
in the REAR seat properly re-
strained at all times in a child

Black plate (33,1)

restraint device or in a seatbelt,
whichever is appropriate for the
child ’s age, height and weight. Se-
cure ALL types of child restraint
devices (including forward facing
child seat) in the REAR seats at all
times.
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
SEAT. DOING SO RISKS SERIOUS
INJURY OR DEATH TO THE CHILD
BY PLACING THE CHILD ’S HEAD
TOO CLOSE TO THE SRS AIRBAG.
According to accident statistics,
children are safer when properly
restrained in the rear seating posi-
tions than in the front seating posi-
tions. For instructions and precau-
tions concerning child restraint sys-
tems, refer to “Child restraint sys-
tems ”F 1-21.
& Forward and backward ad-
justmentPull the lever upward and slide the seat to
the desired position. Then release the
lever and try to move the seat back and
forth to make sure that it is securely locked
into place.
&Reclining the seatbackPull the reclining lever up and adjust the
seatback to the desired position. Then
release the lever and make sure the
seatback is securely locked into place.
The seatback placed in a reclined position
can spring back upward with force when
the lever is pulled. While operating the
lever to return the seatback, hold the
seatback lightly so that it may be raised
back gradually.

WARNING
To prevent the passenger from slid-
ing under the seatbelt in the event of
a collision, always put the seatback
in the upright position while the
vehicle is in motion. Also, do not
place objects such as cushions
between the passenger and the
seatback. If you do so, the risk of
sliding under the lap belt and of the
lap belt sliding up over the abdomen
will increase, and both can result in
serious internal injury or death.
& Seat cushion height adjust-
ment (driver ’s seat)1) When the lever is pushed down, the seat
is lowered.
2) When the lever is pulled up, the seat rises.The height of the seat can be adjusted by
moving the seat cushion adjustment lever
up and down.
&Head restraint adjustment (if
equipped)1) Head restraint
2) Release buttonBoth the driver ’s seat and the front
passenger ’s seat are equipped with head
restraints.
The head restraint should be adjusted so
that the center of the head restraint is
closest to the top of the occupant ’s ears.
To raise:
Pull the head restraint up.
To lower:
Push the head restraint down while
pressing the release button on the top of
the seatback.

To remove:
While pressing the release button, pull out
the head restraint.
To install:
Install the head restraint into the holes that
are located on the top of the seatback until
the head restraint locks.
WARNING
. Never drive the vehicle with the
head restraints removed because
they are designed to reduce the
risk of serious neck injury in the
event that the vehicle is struck
from the rear. Therefore, when
you remove the head restraints,
you must reinstall all head re-
straints to protect vehicle occu-
pants.
. All occupants, including the dri-
ver, should not operate a vehicle
or sit in a vehicle ’s seat until the
head restraints are placed in their
proper positions in order to mini-
mize the risk of neck injury in the
event of a crash.
& Active head restraint (if
equipped)The front seats of your vehicle are
equipped with active head restraints. They
automatically tilt forward slightly in the
event the vehicle is struck from the rear,
decreasing the amount of rearward head
movement and thus reducing the risk of
whiplash. For maximum effectiveness, the
head restraint should be adjusted so that
the center of the head restraint is closest
to the top of the occupant ’s ears.
CAUTION
. Each active head restraint is
effective only when its height is
properly adjusted and driver/pas-
senger sits in the correct posi- tion on the seat.
. If your vehicle is involved in a
rear-end collision, have an
authorized SUBARU dealer in-
spect the active head restraints.
. The active head restraints may
not operate in the event the
vehicle experiences only a slight
impact in the rear.
. The active head restraints may be
damaged if they are pushed hard
from behind or subjected to
shock. As a result, they may not
function if the vehicle suffers a
rear impact.

Seat heater (if equipped)The seat heater is equipped in the front
seats.
The seat heater operates when the igni-
tion switch is either in the “Acc”or “ON ”
position.
CAUTION
. There is a possibility that people
with delicate skin may suffer
slight burns even at low tempera-
tures if they use the seat heater
for a long period of time. When
using the heater, always be sure
to warn the persons concerned.
. Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.NOTEUse of the seat heater for a long period
of time while the engine is not running
can cause battery discharge.
& Type A seat heater1) HI–Rapid heating
2) LO–Normal heating
3) OFF –Off
A) Left-hand side
B) Right-hand side
To turn on the seat heater, push the “LO”
or “HI ”position on the switch, as desired,
depending on the temperature.
Selecting the “HI”position will cause the
seat to heat up quicker.
To turn off the seat heater, lightly press the
opposite side of the current position.
The indicator located on the switch illumi-
nates when the seat heater is in operation.
When the vehicle ’s interior is warmed
enough or before you leave the vehicle,
be sure to turn the switch off.& Type B seat heaterEach seat heater has four levels of
adjustment. To use the heater in the
right-hand seat, turn the “R”adjustment
dial forward until the “
”mark reaches the

Black plate (37,1)
北米Model "A1110BE-C" EDITED: 2010/ 12/ 17
desired position. To activate the heater in
the left-hand seat, turn the “L”adjustment
dial forward until the “
”mark reaches the
desired position. Each heater warms the
seat most quickly with the “
”mark on the
adjustment dial in the furthest-forward
position. An indicator light next to the
adjustment dial for each seat heater
illuminates when that seat heater is
activated.
When the vehicle ’s interior is warmed
enough or before you leave the vehicle,
always turn the adjustment dial to the
most rearward position so that the “
”
mark reaches to the “OFF”position.
Rear seats
WARNING
Seatbelts provide maximum re-
straint when the occupant sits well
back and upright in the seat. Do not
put cushions or any other materials
between occupants and seatbacks
or seat cushions. If you do so, the
risk of sliding under the lap belt and
of the lap belt sliding up over the
abdomen will increase, and both can
result in serious internal injury or
death.
WARNING
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.
