Seatbelts
40This vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seatbelt by the front
passenger when any of the SRS frontal,
side and curtain airbags deploys.▼ Infants or small children
Use a child restraint system that is suit-
able for this vehicle. Refer to "Child
Restraint Systems" P46.
▼ Children
If a child is too big for a child restraint
system, the child should sit in the rear seat
and be restrained using the seatbelts. According to accident statistics, children

are safer when properly restrained in the
rear seating positions than in the front
seating positions. Never allow a child to
stand up or kneel on the seat.
If the shoulder portion of the belt crosses
the face or neck, move the child closer to
the belt buckle to help provide a good
shoulder belt fit. Care must be taken to
securely place the lap belt as low as
possible on the hips and not on the child’s
waist. If the shoulder portion of the belt
cannot be properly positioned, a child
restraint system should be used. Never
place the shoulder belt under the child’s
arm or behind the child’s back.
▼ Expectant mothers
Expectant mothers also need to use the
seatbelts. They should consult their doctor for specific recommendations. The lap

belt should be worn securely and as low
as possible over the hips, not over the
waist.
■ Emergency Locking
Retractor (ELR)The driver’s seatbelt has an Emergency
Locking Retractor (ELR).
The emergency locking retractor allows
normal body movement but the retractor
locks automatically during a sudden stop,
impact or if you pull the belt very quickly
out of the retractor.■ Automatic Locking
Retractor/Emergency
Locking Retractor (ALR/ELR)Each passenger’s seatbelt has an Auto-
matic Locking Retractor/Emergency
Locking Retractor (ALR/ELR). The Auto-
matic Locking Retractor/Emergency
Locking Retractor normally functions as
an Emergency Locking Retractor (ELR).
The ALR/ELR has an additional locking
mode, “Automatic Locking Retractor
(ALR) mode”, intended to secure a child
restraint system.
The ALR mode functions as follows.

positions than in the front seat-
ing positions. For instructions
and precautions concerning the
child restraint system, refer to

slightly, the retractor locks the seatbelt in
that position and the seatbelt cannot be
extended. As the belt is rewinding, clicks
will be heard which indicate the retractor
functions as an ALR. When the seatbelt is
retracted fully, the ALR mode is canceled
and the ELR mode is restored.
When securing a child restraint system on
the rear seats by using a seatbelt, the
seatbelt must be changed over to the
Automatic Locking Retractor (ALR) mode.
For instructions on how to install the child
restraint system using a seatbelt, refer to
"Installing Child Restraint Systems with
ALR/ELR Seatbelt" P51.
When the child restraint system is
removed, make sure that the retractor is
restored to the Emergency Locking
Retractor (ELR) mode by allowing the
seatbelt to retract fully.■ Seatbelt Warning Light
and Chime Refer to "Seatbelt Warning Light and
Chime" P131.
■ Fastening the Seatbelt
WARNING
Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury. Keep the lap belt as low as
possible on your hips. In a colli-
sion, this spreads the force of the
lap belt over stronger hip bones
instead of across the weaker
abdomen. Seatbelts provide maximum
restraint 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 colli-
sion, 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.
 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 place the shoulder belt under
the arm or behind the back. If an
accident occurs, this can increase
the risk or severity of injury.

46NOTEIf the front or side part of the vehicle is
damaged in an accident to the extent
that the seatbelt pretensioner does not
operate, contact your SUBARU dealer
as soon as possible.■ Precautions against Vehicle
ModificationAlways consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
1-6. Child Restraint Systems■ Safety precautionsInfants and small children should always
be placed in an infant or child restraint
system in the rear seat while riding in the
vehicle.
You should use an infant or child restraint
system that meets Federal Motor Vehicle
Safety Standards or Canada Motor
Vehicle Safety Standards, is compatible
with your vehicle and is appropriate for the
child’s age and size.
All child restraint systems are designed to
be secured in vehicle seats by lap belts or
the lap belt portion of a lap/shoulder belt
(except those described in "Installation of
Child Restraint Systems by Use of Lower
and Tether Anchorages (LATCH)" P55).
If you need service or repair in
those areas or near the front
seatbelt retractors, have the work
performed by your authorized
SUBARU dealer.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pretensioners. Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than
genuine SUBARU accessory
parts to the front end.
 Modification of the suspension
system or front end structure. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the driver’s
center pillar or specified for indi-
vidual vehicle models in this
Owner’s Manual.

WARNING
Before installing a child restraint
system, be sure to confirm that
the seatback is securely locked
into place. Otherwise, in an acci-
dent, serious injury or death
could result. Do not leave children in the car
unattended. High interior
temperatures may cause heat
stroke and dehydration that
result in serious injury or death.
100125
WARNING
Never let a passenger hold a child
on his or her lap or in his or her
arms while the vehicle is moving.
The passenger cannot protect the
child (or infant) from injury in a col-
lision, because the child will be
caught between the passenger and
objects inside the vehicle. Addition-
ally, holding a child in your lap or
arms in the front seat exposes that
child to another serious danger.
Since the SRS airbag deploys with
considerable speed and force, the
child could be injured or even killed.

48■Safety Tips for Installing
Child Restraint Systems
■Where to Place a Child
Restraint SystemThe following descriptions are SUBARU’s
recommendations on where to place a
child restraint system in your vehicle.
WARNING
Children should be properly
restrained at all times. Never allow a
child to stand up, or to kneel on any
seat. Unrestrained children will be
thrown forward during sudden stop
or in an accident and can be injured
seriously.Additionally, children standing up
or kneeling on or in front of the
front seat are exposed another seri-
ous danger. Since the SRS airbag
deploys with considerable speed
and force, the child could be injured
or even killed.
WARNING
 Child restraint systems and
seatbelts can become hot in a
vehicle that has been closed up in
sunny weather; they could burn a
small child. Check the child
restraint system before you place
a child in it.
 Do not use a seatbelt extender. If
a seatbelt extender is used when
installing a child restraint system,
the seatbelt will not securely hold
the child restraint system. Use of
a seatbelt extender could cause
death or serious injury to children
or other passengers in sudden
braking, swerving, or accidents. Attach the child restraint system
to the anchors properly. When
using the LATCH anchors, be
sure that there are no foreign
objects around the anchors.
Make sure the child restraint
system is securely attached.
Otherwise it may cause death or
serious injury to children or other
passengers in sudden braking,
swerving, or accidents. Do not leave an unsecured child
restraint system in your vehicle.
Unsecured child restraint
systems can be thrown around
inside of the vehicle in a sudden
stop, turn or accident; they can
strike and injure vehicle occu-
pants as well as result in serious
injuries or death to the child.
CAUTION
When you install a child restraint
system, follow the manufacturer’s
instructions supplied with it. After
installing the child restraint system,
check to ensure that it is held
securely in position. If it is not held
tight and secure, the danger of your
child suffering personal injury in
the event of an accident may be
increased.
WARNING
 Several types of child restraint
systems may conceal the buckle
of the neighboring seat. If the
occupant of the neighboring seat
cannot correctly fasten the
seatbelt, that person must move
to a different seat. If the seatbelt
cannot be correctly fastened,
there is the risk of serious injury
or death in the event of sudden
braking or a collision.

A: Front passenger’s seat
You should not install a child restraint
system (including a bo oster seat) due to
the hazard to children posed by the
passenger’s airbag.
B: Rear seat
Recommended positions for all types of
child restraint systems. In these positions, the following equip-
ment is provided for installing a child

restraint system.
 Automatic Locking Retractor/Emer-
gency Locking Retractor (ALR/ELR)
seatbelts
 Lower anchorages (bars)
 Upper anchorages (tether anchorages)
Some types of child restraint systems
might not be able to be secured firmly due
to projection of the seat cushion.
In this seating position, you should use
only a child restrain t system that has a
bottom base that fits snugly against the
contours of the seat cushion and can be
securely retained using the seatbelt. If the child restraint system
cannot be correctly installed
because it contacts the driver’s
seat, move the child restraint
system to a different seat. If it
cannot be installed in a different
seat (other than the driver’s seat),
adjust the front seat so that
contact does not occur.
102673
WARNING
 Even with advanced airbags, chil-
dren can be seriously injured by
the airbag. Seat children 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 not
restrained or improperly
restrained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater.
For that reason, be sure to secure
ALL types of child restraint systems
in the REAR seats at all times. You
should choose a restraint system
which is appropriate for the child’s
age, height and weight. According
to accident statistics, children are
safer when properly restrained in
the rear seating positions than in
the front seating positions. Do not connect tw o or more lower
hooks onto the same anchorage
(bar).

■Choosing a Child Restraint
SystemChoose a child restraint system that is
appropriate for the child’s age and size
(weight and height) in order to provide the
child with proper protection. The child
restraint system should meet all appli-
cable requirements of Federal Motor
Vehicle Safety Standards for the United
States or of Canada Motor Vehicle Safety
Standards for Canada. It can be identified
by looking for the label on the child
restraint system or the manufacturer's
statement of complia nce in the document
attached to the system. Al so it is important
for you to make sure that the child restraint
system is compatible with the vehicle in
which it will be used.
NOTESome sizes of child restraint systems
may not fit the vehicle seat. Before
purchasing a child restraint system,
check whether it fits on the vehicle
seat.
WARNING
 SINCE YOUR VEHICLE IS
EQUIPPED WITH A
PASSENGER’S SRS AIRBAG,
NEVER INSTALL A CHILD
RESTRAINT SYSTEM IN THE
FRONT PASSENGER’S SEAT.
DOING SO RISKS SERIOUS
INJURY OR DEATH TO THE
CHILD BY PLACING THE CHILD’S
HEAD TOO CLOSE TO THE SRS
AIRBAG. Do not allow children to lean their
heads or any other parts of their
bodies against the door or the
area of the seat, front and rear
pillars or roof side rails. The SRS
side airbags and SRS curtain
airbags deploy even if children
are seated in the child restraint
system, and the impact could
cause death or serious injury to
the child. To secure the child restraint
system, be sure to comply with all
installation instructions provided
by the child restraint system
manufacturer. Not doing so could
result in death or serious injury to
children in a sudden stop or acci-
dent.
