WARNING

■

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 choking 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 system left and right, and forward and backward to ensure

that it has been securely installed.

●

After securing a child restraint system, never adjust the seat.

●

When 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.

●

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 may result in death or serious

injury.

●

When installing a child restraint system in the rear center seat, adjust both seat cush-

ions 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.

■

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 only. 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 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.

■

When installing in the rear outboard seats
Install the child restraint system in accordance to the operation manual
enclosed with the child restraint system.

If there is a gap between the child seat and the seatback, adjust the seat-
back angle until good contact is achieved.
Remove the head restraint if it
interferes with your child restraint
system. (

P. 177)

If the head restraint cannot be

removed, raise it to the uppermost

position.

■

When installing in the rear center seat
There are no LATCH anchors behind the 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 restraint 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 FMVSS213 or CMVSS213 specifications can be

used.

This vehicle is designed to conform to SAE J1819.

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 caught behind the child restraint system.

●

Follow all installation instructions 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 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 may result in death or serious

injury.

●

When installing a child restraint system in the rear center seat, adjust both seat cush-

ions 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 adjusted, reconfirm the security of the child restraint system.
