'06 TUNDRA_U (L/O 0508) CAUTION Make sure the both buckles are correctly located and securely latched. Failure to properly match the buckle and tab may cause severe injury in case of an accident or a collision. To release the concave end tab, insert the key into the hole on buckle 1 (with light gray buckle release button) and allow the belt to retract. CAUTION Do not use the center seat belt with either buckle released. Fastening only the shoulder belt or lap belt may cause severe personal injury in case of sudden braking or a collision. 68 2006 TUNDRA from Oct. '06 Prod. (OM34458U)
