When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury.
CAUTIONWhen using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.
CAUTIONDo not use electrical test equipment to check SRS circuits unless instructed to.
CAUTIONDiagnosis sensor unit must always be installed with their arrow marks pointing towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installation and replace as required.
CAUTIONThe spiral cable must be aligned in the neutral position since its rotations are limited. Do not turn steering wheel and column after removal of steering gear.
CAUTIONHandle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
CAUTIONNever insert any foreign objects (screwdriver, etc.) into the driver air bag module.
CAUTIONNever disassemble the driver air bag module.
CAUTIONNever expose the driver air bag module to temperatures exceeding 194°F (90°C).
CAUTIONNever allow oil, grease, detergent, or water to come in contact with the driver air bag module.
CAUTIONWhen carrying or handling an undeployed airbag, the trim side (face) of the airbag should be pointing away from the body to minimize possibility of injury if accidental deployment occurs. Failure to do this may result in personal injury or death.
CAUTIONReplace airbag system components with OEM replacement parts. Substitute parts may appear interchangeable, but internal differences may result in inferior occupant protection. Failure to do so may result in occupant personal injury or death.
CAUTIONWear safety glasses, rubber gloves, and long sleeved clothing when cleaning powder residue from vehicle after an airbag deployment. Powder residue emitted from a deployed airbag can cause skin irritation. Flush affected area with cool water if irritation is experienced. If nasal or throat irritation is experienced, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician.
CAUTIONDo not use a replacement airbag that is not in the original packaging. This may result in improper deployment, personal injury, or death.
The factory installed fasteners, screws and bolts used to fasten airbag components have a special coating and are specifically designed for the airbag system. Do not use substitute fasteners. Use only original equipment fasteners listed in the parts catalog when fastener replacement is required.
If equipped with OCS, the front passenger seat must be handled carefully as well. When removing the seat, be careful when setting on floor not to drop. If dropped, the sensor may be inoperative, could result in occupant injury, or possibly death.
