RX450h_RX450hL _U_OM48F85UWARNING ■
When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to chokin g or other serious injuries that could result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut the
belt. ●
Ensure that the belt and plate are securely locked and the seat belt is not twisted.●
Shake the child restraint syst em left and right, and forward and backward to ensure
that it has been securely installed. ●
After securing a child restraint system, ne ver adjust the seat.●
When a booster seat is installed, always en sure 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 coul d fall off the child’s shoulder.●
Follow all installation instructions provided by the child restraint system manufacturer.●
When securing some types of child restraint systems in rear seats, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without inter-
fering 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 ma y result in death or serious
injury. ●
When installing a child restraint system in th e rear center seat, adjust both seat cush-
ions to the same position an d align both seatbacks at th e same angle. The seatbacks
must be adjusted to the same angle. Othe rwise, the child restra int system cannot be
securely restrained and this may cause death or serious injuries in the event of sudden
braking, sudden swerving or an accident. ■
When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten on ly. This could cause injury or discomfort to
the child. ( → P. 33)■
Do not use a seat belt extender
If a seat belt extender is used when insta lling 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.

When installing in the rear center seat
There are no LATCH anchors behind th e rear center seat. However, the
inboard LATCH anchors of the outboard seats, which are 18.1 in. (460 mm)
apart, can be used if the child restrain t system manufacturer’s instructions per-
mit use of those anchors with the anchor spacing stated.
Child restraint systems with rigid lower 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 FMV SS213 or CMVSS213 specifications can be

WARNING ■
When installing a child restraint system
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 ca ught behind the child restraint system.●
Follow all installation instructions provided by the child restraint system manufacturer.●
Never attach two child restrain t system attach ments 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 inst all a child restraint
system in the center seat. ●
When securing some types of child restraint systems in rear seats, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without inter-
fering 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 ma y result in death or serious
