Page 44 1-1. For safe use SRS airbag deployment conditions (SRS front airbags) ■ The SRS front airbags will deploy in the event of an impact that exceeds the set thresh- ● old level (the level of force corresponding to an approximately 12 - 18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).
Page 45 1-1. For safe use Types of collisions that may not deploy the SRS airbags (SRS front airbags) ■ The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a collision of any type causes sufficient forward deceleration of the vehicle, deployment of the SRS front airbags may occur.

Page 54: Child Restraint Systems
1-1. For safe use Child restraint systems A child restraint system for a small child or baby must itself be properly restrained on the seat with the LATCH anchors or the lap portion of the lap/ shoulder belt. The laws of all 50 states of the U.S.A. and Canada now require the use of child restraint systems.

Page 57 1-1. For safe use CAUTION When children are in the vehicle ■ 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.
Page 58: Installing Child Restraints
1-1. For safe use Installing child restraints Follow the child restraint system manufacturer’s instructions. Firmly secure child restraints to the seats using the LATCH anchors or a seat belt. Attach the top tether strap when installing a child restraint. The lap/shoulder belt can be used if your child restraint system is not compati- ble with the LATCH (Lower Anchors and Tethers for Children) system.
Page 59 1-1. For safe use Installation with LATCH system Remove the head restraint if it interferes with your child restraint system. Type A  Latch the hooks of the lower straps onto the LATCH anchors. If the child restraint has a top tether strap, the top tether strap should be latched onto the top tether strap anchor.
Page 60 1-1. For safe use Type B  Latch the buckles onto the LATCH anchors. If the child restraint has a top tether strap, the top tether strap should be latched onto the top tether strap anchor. For owners in Canada: The symbol on a child restraint system indicates the presence of a lower connector system.
Page 61 1-1. For safe use Installing child restraints using a seat belt (child restraint lock function belt) Rear-facing  Infant seat/convertible seat ■ Place the child restraint system on the rear seat facing the rear of the vehicle. Run the seat belt through the child restraint system and insert the plate into the buckle.
Page 62 1-1. For safe use While pushing the child restraint system down into the rear seat, allow the shoulder belt to retract until the child restraint system is securely in place. After the shoulder belt has retracted to a point where there is no slack in the belt, pull the belt to check that it cannot be extended.
Page 63 1-1. For safe use Run the seat belt through the child restraint system and insert the plate into the buckle. Make sure that the belt is not twisted. Fully extend the shoulder belt and allow it to retract to put it in lock mode.
Page 64 1-1. For safe use Booster seat ■ Place the child restraint system on the seat facing the front of the vehicle. Sit the child in the child restraint system. Fit the seat belt to the child restraint system according to the manufacturer’ s instructions and insert the plate into the buckle.
Page 65 1-1. For safe use Child restraint systems with a top tether strap Remove the head restraint if it inter- feres with your child restraint system. Secure the child restraint system using the seat belt or LATCH anchors. Open the anchor bracket cover, latch the hook onto the anchor bracket and tighten the top tether strap.
Page 66 1-1. For safe use CAUTION 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.
Page 67 1-1. For safe use CAUTION When installing a child restraint system ■ When using the LATCH anchors for a child restraint system, move the seat as far ● back as possible, with the seatback close to the child restraint system. When a booster seat is installed, always ensure that the shoulder belt is positioned ●...
