When not using the child restraint system, keep it secured with the seat belt. This will prevent it from injuring passengers in the event of a sudden stop or accident. Your vehicle has anchors for securing the top strap of a child restraint system. The anchor nuts are welded beneath the sheet metal to permit installation of an anchor bracket for a child restraint system. To install an anchor bracket, use an 8 mm X 30 mm X 1.25 mm coarse thread metric bolt and a 10 mm (0.4 in.) spacer. Note that the bolts accompanying many child restraint systems are not metric. You can damage the anchor nuts on your vehicle if you force bolts with different thread into the anchor nuts. For instructions about how to install the anchor bracket, see "Top strap anchors and locations". If your child restraint system does not provide any of the necessary parts, you can purchase the following items from your Toyota dealer. S CRS installation kit (Part No. 04731−22012) −contains 1 bolt, 3 types of spacers and 1 locking clip. 40 S Bolt (Part No. 91511−60830)
