491-2. Child safety
1
For safety and security
WARNING
●Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-facing child restraint
system is installed on the front passen-
ger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, adjust the seatback angle to the
most upright position, move the seat to
the rearmost position, and raise the
seat to the upper most position, even if
the “AIR BAG OFF” indicator light is
illuminated.
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or th e area of the seat,
front or rear pillars, or roof side rails
from which the SRS side airbags or
SRS curtain shield airbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Use child restraint system suitable to
the age and size of the child and install
it to the rear seat.
●If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.

■Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the agent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
Safety Connect LED light Indi-
cators
