A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.
■Installing child restraint system

Adjust the seatback
If there is a gap between the child seat and
the seatback, adjust the seatback until
good contact is achieved.
WARNING
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front 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 seri-
ous 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.
When using a child restraint sys-
tem on a rear seat
WARNING

tem
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous injury.
●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.

■Card key (if equipped)
●The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card
key does not operate properly.
●If the battery cover is not installed and the
battery falls out or if the battery was

aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an

the buttons are not likely to be pressed acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.

●The standard battery life is 1 to 2 years.
(The card key battery life is about a year
and a half.)

sound in the cabin wh en the hybrid sys-
tem stops.
●To reduce key battery depletion when the
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. ( P.125)
●As the electronic key always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( P.368)
• The smart access system with push-but-
ton start or the wireless remote control
