501-2. Child safety
QChild restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seat. (Marks displaying
the location of the anchors are
attached to the seats.)
WARNING
QWhen installing a child restraint sys-
tem
Observe the following precautions.
Failure to do so may result in death or
serious injury.
ODo not allow children to play with the
seat belt. If the seat belt becomes
twisted around a child’s neck, it may
lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.
OEnsure that the belt and plate are
securely locked and the seat belt is not
twisted.
OShake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.
OAfter securing a child restraint system,
never adjust the seat.
OWhen a booster seat is installed,
always ensure that the 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.
OFollow all installation instructions pro-
vided by the child restraint system
manufacturer.
OWhen 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 effectiveness. 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 different
position. Failure to do so may result in
death or serious injury.
QWhen installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This co uld cause injury or
discomfort to the child. ( P.26)
QDo not use a seat belt extender
If a seat belt extender is used when
installing a child restraint system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.

transmitter and receiver. It receives
and also sends out radio frequency
(RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
