Safety Precautions When Driving
9
Introduction
– CONTINUED –
■Use of Cell Phones/Texting
and Driving■Driving Vehicles Equipped
with Audio System
■Driving with PetsUnrestrained pets can interfere with your
driving and distract your attention from
driving. In a collision or sudden stop, unre-
strained pets or cages can be thrown
around inside the vehicle and hurt you or
your passengers. Besides, the pets can
be hurt under these situations. It is also for
their own safety that pets should be prop-
erly restrained in your vehicle. Restrain a
pet with a special traveling harness which
can be secured to the rear seat with a
seatbelt or use a pet carrier which can be
secured to the rear seat by routing a
seatbelt through the carrier’s handle.
Never restrain pets or pet carriers in the
front passenger’s seat. For further infor-
mation, consult your veterinarian, local
animal protection society or pet shop.■ Tire PressuresCheck and, if necessary, adjust the pres-
sure of each tire and the spare (if
equipped) at least once a month and
before any long journey.
Check the tire pressure when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire inflation pressure label. For detailed
information, refer to "Tires and Wheels"
 P358.
■ Attaching Accessories
CAUTION
Do not talk on a cell phone or text
while driving; it may distract your
attention from driving and lead to
an accident. If you use a cell phone
to talk or text, fi rst pull off the road
and park in a safe place. In some
States/Provinces, it may be lawful to
talk on a phone while driving, but
only if the phone is hands-free.
WARNING
Do not allow the monitor to distract
your attention from driving. Also,
do not operate the controls of the
audio system while driving. The
loss of attention to driving could
lead to an accident. If you wish to
operate the controls of the audio
system, first take the vehicle off the
road and stop it in a safe location.
WARNING
Driving at high speeds with
excessively low tire pressures
can cause the tires to deform
severely and to rapidly
become hot. A sharp increase
in temperature could cause
tread separation, and destruc-
tion of the tires. The resulting
loss of vehicle control could
lead to an accident.
WARNING
 Do not attach any accessories,
labels or sticke rs (other than
properly placed inspection
stickers) to the windshield. Such
items may obstruct your view. If it is necessary to attach an
accessory (such as an electronic
toll collection (ETC) device or
security pass) to the windshield,
consult your SUBARU dealer for
details on the proper location.

Front Seats
301-1. Front Seats
WARNING
Never adjust the seat while
driving, as personal injury or loss
of vehicle control may occur. Before adjusting the seat, ensure
nothing is blocking the adjusting
mechanism. After adjusting the seat, move it
back and forth to ensure the seat
is securely locked. If it is not, it
may move suddenly or the
seatbelt may not operate prop-
erly. Do not put objects under the front
seats. They may interfere with
front seat locking mechanism
and cause an accident.
 Seatbelts provide maximum
restraint when the occupant sits
back and upright in the seat. To
reduce the risk of sliding under
the seatbelt in a collision, the
front seatbacks should always be
used in the upright position while
the vehicle is running. If the front
seatbacks are not in the upright
position and a collision occurs,
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
injury or death. The SRS airbags deploy with
considerable speed and force.
Occupants who are not sitting
back and upright when the SRS
airbag deploys could suffer
serious injury. Because the SRS
airbag needs enough space for
deployment, 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
Seat children in the rear seat prop-
erly 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 deploy-
ment is greater. For that reason, we
strongly recommend that ALL chil-
dren (including those in child
restraint systems) sit in the REAR
seat properly restrained at all times
in a child restraint system or in a
seatbelt, whichever is appropriate
for the child’s age, height and
weight. Secure ALL types of child
systems in the REAR seats at all
times.NEVER INSTALL A CHILD
RESTRAINT SYSTEM 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
precautions concerning child
restraint systems, refer to "Child
Restraint Systems" P46.
100807
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 cush-
ions 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 abdo-
men will increase, and both can
result in serious internal injury or
death.

WARNING
Seatbelts provide maximum
restraint when the occupant sits
back and upright in the seat. Do not
place cushions or any other materi-
als between occupants and
seatbacks or seat cushions. By
doing so, the risk of sliding under
the lap belt and of the lap belt slid-
ing up over the abdomen will
increase, and both can result in
serious internal injury or death.
102931
WARNING
 When folding down the seatback,
check that there are no passen-
gers or objects on the rear seat.
Not doing so creates a risk of
injury or property damage. Never allow passengers to ride
on the folded rear seatback or in
the trunk. Doing so may result in
serious injury or death. Secure all objects and especially
long items properly to prevent
them from being thrown around
inside the vehicle and causing
serious injury during a sudden
steering maneuver or accelera-
tion. When you return the seatback to
its original position, shake it
slightly to confirm that it is
securely in place. If it is not
securely fixed in place, it may
suddenly fold down in the event
of sudden braking, or objects
may move out from the trunk,
both could cause serious injury
or death.
WARNING
When the seatback is returned to its
original position, observe the fol-
lowing precautions. Failure to do so
may lead to serious injury or an
accident because the proper
seatbelt operation will be affected. The seatbelt should not be
caught in the seatback and it
should be fully visible.

WARNING
All persons in the vehicle should
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent. All belts should fit snugly in order
to provide full restraint. Loose
fitting belts are not as effective in
preventing or reducing injury. Each seatbelt is designed to
support only one person. Never
use a single belt for two or more
persons – even children. Other-
wise, in an accident, serious
injury or death could result.
 Replace all seatbelt assemblies
including retractors and
attaching hardware worn by
occupants of a vehicle that has
been in a serious accident. Also,
be sure to replace seatbelt
assemblies that show signs of
severe fraying or having been
cut. The entire assembly should
be replaced even if damage is not
obvious. 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 chil-
dren, 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, we strongly recommend
that ALL children (including
those in child restraint systems)
sit in the REAR seat properly
restrained at all times in a child
restraint system or in a seatbelt,
whichever is appropriate for the
child’s height and weight. Secure
ALL types of child restraint
systems in the REAR seats at all
times.

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.
When the seatbelt is once drawn out
completely and is then retracted even
NEVER INSTALL A CHILD
RESTRAINT SYSTEM 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
positions than in the front seat-
ing positions. For instructions
and precautions concerning the
child restraint system, refer to
"Child Restraint Systems" P46.

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.
