WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●When using the LATCH
anchors, be sure that there are
no foreign objects around the
anchors and that the seat belt is
not caught behind the child
restraint system.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.
●Never attach two child restraint
system attachments to the
same anchor. In a collision, one
anchor may not be strong
enough to hold two child
restraint system attachments
and may break.
If the LATCH anchors are
already in use, use the seat belt
to install a child restraint system
in the center seat.
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting seat belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, move to a differ-
ent position. Failure to do so
may result in death or serious
injury.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.

Before driving
message will be displayed on the
multi-information display for approx-
imately 6 seconds.
Also, as the second reminder, when
the doors are locked, a buzzer will
sound and the emergency flashers
will flash for a few seconds, and a
message will be displayed on the
multi-information display.
●The hybrid system is started
within approximately 10 minutes
after opening and closing a rear
door.
●A rear door has been opened and
closed after the hybrid system
was started.
The second reminder will not be
activated if a rear door was opened
before the doors are locked.
However, if a rear door is opened
and then closed within approxi-
mately 2 seconds, the rear seat
reminder function may not operate.
The rear seat reminder function
determines that luggage, etc. has
been placed in a rear seat based on
opening and closing of a rear door.
Therefore, depending on the situa-
tion, the rear seat reminder function
may not operate and you may still
forget luggage, etc. in the rear seat,
or it may operate unnecessarily.
■Open door warning buzzer
If the vehicle speed reaches 3 mph
(5 km/h), a buzzer sounds to indi-
cate that the door(s) or the hood is
not fully closed.
The open door(s) or hood is dis-
played on the multi-information dis-
play.

The rear seat reminder function can
be enabled/disabled. (Customiz-
able features: P.618)The door cannot be opened
from inside the vehicle when the
lock is set.
WARNING
■To prevent an accident
Observe the following precautions
while driving the vehicle.
Failure to do so may result in a
door opening and an occupant
could be thrown out of the vehicle,
resulting in death or serious
injury.
●Ensure that all doors are prop-
erly closed and locked.
●Do not pull the inside handle of
the doors while driving.
Be especially careful for the
front doors, as the doors may
be opened even if the inside
lock buttons are in locked posi-
tion.
●Set the rear door child-protector
locks when children are seated
in the rear seats.
■When opening or closing a
door
Check the surroundings of the
vehicle such as whether the vehi-
cle is on an incline, whether there
is enough space for a door to
open and whether a strong wind
is blowing. When opening or clos-
ing the door, hold the door handle
tightly to prepare for any unpre-
dictable movement.
