Toyota Sienna 2010-2025 Owners Manual: Child restraint systems with a top tether strap (third seat)

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.

When installing a child restraint system

Follow the directions given in the child restraint system installation manual and fix the child restraint system securely in place.

If the child restraint system is not correctly fixed in place, the child or other passengers may be seriously injured or even killed in the event of sudden braking, sudden swerving or an accident.

• If the driver’s seat interferes with the child restraint system and prevents it from being attached correctly, attach the child restraint system to the right-hand rear seat.

• Adjust the front passenger seat or second seats so that it does not interfere with the child restraint system.
• Only put a forward-facing child restraint system on the front seat when unavoidable.

  When installing a forward-facing child restraint system on the front passenger seat, move the seat as far back as possible even if the “AIR BAG OFF” indicator light is illuminated. Failure to do so may result in death or serious injury if the airbags deploy (inflate).

When installing a child restraint system

• When installing a child restraint system on the third center seat, adjust both seatbacks at 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 using the LATCH anchors for a child restraint system, move the seat as far back as possible (second seat only), with the seatback close to the child restraint system.
• 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. Failing to do so may result in death or serious injury in the event of sudden braking, sudden swerving or an accident.
• 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.
• Follow all installation instructions provided by the child restraint system manufacturer.
• When securing some types of child restraint systems in second (8-passenger models) or third row 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 dose 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 to the AUTO ACCESS SEAT (if equipped)

• Do not operate the AUTO ACCESS SEAT while a child restraint system is fixed to the seat by the child restraint lock function belt.

  If you force the seat operation, the seat, seat belt or child restraint system may be damaged, or may cause an injury.

• If a child restraint system is fixed to the AUTO ACCESS SEAT by the LATCH system, be careful that the child’s head, hands and legs do not hit the body of the vehicle when operating the seat.

  Injuries may be caused.

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.

To correctly attach a child restraint system to the anchors

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. Make sure the child restraint system is securely attached, or it may cause death or serious injury to the child or other passengers in the event of a sudden braking, sudden swerving or an accident.
