There are no LATCH anchors behind

board seats, which are 18.1 in. (460
mm) apart, can be used if the child
restraint system manufacturer’s
instructions permit use of those anchors with the anchor spacing
stated.

attachments cannot be installed in the
center seat. This type of child restraint
system can only be installed in the out-
board seat.
■Laws and regulations pertaining to
anchors
The LATCH system conforms to
FMVSS225 or CMVSS210.2.
Child restraint systems conforming to
FMVSS213 or CMVSS213 specifications
can be used.
This vehicle is designed to conform to SAE

WARNING
■When installing a child restraint sys-
tem
Observe the following precautions.
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 instructions pro-
vided 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 at tachments 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.

WARNING
●When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
seat belts in position s next to the child
restraint without inte rfering 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 posi-
tion. Failure to do so may result in
death or serious injury.
●When installing a child restraint system
in the rear center seat, adjust both seat
cushions to the same position and
align both seatbacks at the same
angle. The seatbacks must be adjusted
to the same angle. Otherwise, the
child restraint system cannot be
securely restrained and this may cause
death or serious injuries in the event of
sudden braking, sudden swerving or
an accident.
●If the seat is adju sted, reconfirm the
security of the child restraint system.
