WARNING
■SRS airbag
●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 children are lighter
and weaker than adults, their risk of
being injured from deployment is
greater.
For that reason, we strongly recom-
mend that ALL children (including those
in child seats and those that have out-
grown child restraint devices) sit in the
REAR seat properly restrained at all
times in a child restraint device or in a
seatbelt, whichever is appropriate for
the child's age, height and weight.
Secure ALL types of child restraint
devices (including forward facing child
seats) in the REAR seats at all times.
According to accident statistics, chil-
dren are safer when properly restrained
in the rear seating positions than in the
front seating positions.
For instructions and precautions con-
cerning the child restraint system, refer
to “Child restraint systems”. ( →P. 141)

104 1-7. Safety information

■If the front passenger’s frontal airbag ON indicator illuminates and the
OFF indicator turns off even when an in fant or a small child is in a child
restraint system (including booster seat)
Turn the ignition switch to the “LOCK” position (vehicles without a keyless
access with push button start system), or turn the push-button ignition switch
off (vehicles with a keyless access with push button start system) if the front
passenger’s frontal airbag ON indicator illuminates and the OFF indicator
turns off even when an infant or a small child is in a child restraint system
(including booster seat). Remove the child restraint system from the seat. By
referring to the child restraint manufacturer’s recommendations as well as
the child restraint system installation procedures in “Child restraint systems”
( → P. 141), correctly install the child restraint system. Turn the ignition switch
to the “ON” position (vehicles without a keyless access with push button start
system), or turn the push-button ignition switch to the “ON” mode (vehicles
with a keyless access with push button start system) and make sure that the
front passenger’s frontal airbag ON indicator turns off and the OFF indicator
illuminates.
If still the ON indicator remains illuminated while the OFF indicator turns off,
take the following actions.
● Ensure that no article is placed on the seat other than the child restraint
system and the child occupant.
● Ensure that the backward-forward position and seatback of front passen-
ger’s seat are locked into place securely by moving the seat back and
forth.
If the ON indicator still remains illuminated while the OFF indicator turns off
after taking relevant corrective actions described above, relocate the child
restraint system to the rear seat and immediately contact your SUBARU
dealer for an inspection.
NOTE
When a child who has outgrown a child restraint system or a small adult is
seated in the front passenger’s seat, the SUBARU advanced frontal airbag
system may or may not activate the front passenger’s SRS frontal airbag
depending on the occupant’s seating posture. The child should always wear
the seatbelt when sitting in the seat irrespective of whether the airbag is
deactivated or activated. If the front passenger’s SRS frontal airbag is acti-
vated (the ON indicator remains illuminated while the OFF indicator turns
off), take the following actions.

WARNING
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seatbelt should be properly secured using a child restraint sys-
tem. SUBARU strongly recommends that all infants and children be placed
in the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( →P. 141)
●Do not sit on the edge of the seat or
lean against the dashboard.
● Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.

138 1-7. Safety information
BRZ_UVehicles without a keyless access with push button start sys-
tem:
The engine switch is turned to the “ON” position and make
sure that the front passenger’s frontal airbag ON indicator
turns off and the OFF indicator illuminates.
Vehicles with a keyless access with push button start system:
The push-button ignition switch is turned to “ON” mode and
make sure that the front passenger’s frontal airbag ON indica-
tor turns off and the OFF indicator illuminates.
If the ON indicator still remains illuminated while the OFF indi-
cator turns off, perform the following.
• Ensure that no article is placed on the seat other than the
child restraint system and the child occupant.
• Ensure that the backward-forward position and seatback of front passenger seat are locked into place securely by mov-
ing the seat back and forth.
If the ON indicator still remains illuminated while the OFF indi-
cator turns off after taking the relevant corrective actions
described above, relocate the child restraint system to the
rear seat and immediately contact your SUBARU dealer for
an inspection.

Selecting an appropriate child restraint system
● Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seatbelt.
● If a child is too large for a child restraint system, sit the child on a rear
seat and use the vehicle's seatbelt. ( →P. 60)
■ Where to place a child restraint system
The following are SUBARU’s recommendations on where to place a child
restraint system in your vehicle.
● Front passenger’s seat
Do not install a child restraint system (including a booster cushion) due to
the hazard to children posed by the passenger’s airbag.
● Rear seat seating positions
Recommended installing positions for the child restraint systems.
In these positions, the following equipment is provided for installing a child
restraint system.
• Automatic/Emergency Locking Retractor (ALR/ELR) seatbelts
• ISOFIX anchor bars
• Top tether anchorages
Some types of child restraints 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 restraint system that
has a bottom base that fits snugly against the contours of the seat cushion
and can be securely retained using the seatbelt. Front passenger’s seat
