The SRS airbag deploys with
considerable speed and force
and can injure or even kill chil-
dren, especially if they are 12
years of age and under and are
not restrained or improperly re-
strained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
. NEVER INSTALL A REARWARD
FACING CHILD SEAT IN THE
FRONT SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THECHILD ’S HEAD TOO CLOSE TO
THE SRS AIRBAG.
. Always turn the child safety locks
to the “LOCK ”position when
children sit in the rear seat.
Serious injury could result if a
child accidentally opens the door
and falls out. Refer to “Child
safety locks ”F 2-20.
. Always lock the passenger ’s win-
dows using the lock switch when
children are riding in the vehicle.
Failure to follow this procedure
could result in injury to a child
operating the power window. Re-
fer to “Windows ”F 2-20. .
Never leave unattended children,
adults or animals in the vehicle.
They could accidentally injure
themselves or others through
inadvertent operation of the ve-
hicle. Also, on hot or sunny days,
temperature in a closed vehicle
could quickly become high en-
ough to cause severe or possibly
fatal injuries to them.
. Help prevent children, adults or
animals from locking themselves
in the trunk. On hot or sunny
days, the temperature in the
trunk could quickly become high
enough to cause death or serious
heat-related injuries including
brain damage to anyone locked
inside, particularly for small chil-dren.
. When leaving the vehicle, either
close all windows and lock all
doors. Also make certain that the
trunk is closed.
For instructions and precautions, carefully
read the following sections. . For the seatbelt system, refer to “Seat-
belts ”F 1-11.
. For the child restraint system, refer to
“ Child restraint systems ”F 1-21. .
For the SRS airbag system, refer to
“ *SRS airbag (Supplemental Restraint
System airbag) ”F 1-34.
& Engine exhaust gas (carbon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure

1-2Seat, seatbelt and SRS airbags
Front seats
WARNING
. Never adjust the seat while driv-
ing to avoid loss of vehicle con-
trol and 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 anaccident.
. 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

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, seatbelt and SRS airbags

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 isactivated.
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 ordeath.
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. Seat, seatbelt and SRS airbags
