Print Back to Top Lexus RXh, Hybrid 3 Disarming the System To avoid personal injury when working on vehicles equipped with an air bag, the negative battery cable must be disconnected and at least 90 seconds must elapse before working on the system.

Failure to do so may result in deployment of the air bag. Print Lexus RXh, Hybrid 3 Service Precautions Disconnect and isolate the battery negative cable before beginning any airbag system component diagnosis, testing, removal, or installation procedures. Allow system capacitor to discharge for two minutes before beginning any component service. This will disable the airbag system.

Failure to disable the airbag system may result in accidental airbag deployment, personal injury, or death. Do not place an intact undeployed airbag face down on a solid surface.

The airbag will propel into the air if accidentally deployed and may result in personal injury or death. When carrying or handling an undeployed airbag, the trim side face of the airbag should be pointing towards the body to minimize possibility of injury if accidental deployment occurs.

Failure to do this may result in personal injury or death. Replace 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. Wear 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 Chassis Electrical Back to Top irritation is experienced, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician.

Do 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. During, and following, any child restraint anchor service, due to impact event or vehicle repair, carefully inspect all mounting hardware, tether straps, and anchors for proper installation, operation, or damage. If a child restraint anchor is found damaged in any way, the anchor must be replaced.

Deployed and non-deployed airbags may or may not have live pyrotechnic material within the airbag inflator. Refer to the Hazardous Substance Control System for proper disposal.

Dispose of deployed airbags and tensioners consistent with state, provincial, local, and federal regulations.

After any airbag component testing or service, do not connect the battery negative cable. Personal injury or death may result if the system test is not performed first. If the vehicle is equipped with the Occupant Classification System OCS , do not connect the battery negative cable before performing the OCS Verification Test using the scan tool and the appropriate diagnostic information.

Personal injury or death may result if the system test is not performed properly. If both require replacement, replace one, then perform the Airbag System test before replacing the other. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and cause personal injury or death.

Do not drop or handle roughly. If dropped or damaged, replace with another sensor. Failure to do so may result in occupant injury or death. 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. If equipped with OCS, when the passenger front seat is on the floor, no one should sit in the front passenger seat.

This uneven force may damage the sensing ability of the seat weight sensors. If sat on and damaged, the sensor may be inoperative, could result in occupant injury, or possibly death. The system must be disarmed before performing service on, or around, system components, the steering column, instrument panel components, wiring and sensors.

Failure to follow the safety precautions and the disarming procedure could result in accidental air bag deployment, possible injury and unnecessary system repairs.

Print Back to Top Lexus RXh, Hybrid 3 Disarming the System To avoid personal injury when working on vehicles equipped with an air bag, the negative battery cable must be disconnected and at least 90 seconds must elapse before working on the system.

Failure to do so may result in deployment of the air bag. Print Lexus RXh, Hybrid 3 Service Precautions Disconnect and isolate the battery negative cable before beginning any airbag system component diagnosis, testing, removal, or installation procedures.

Allow system capacitor to discharge for two minutes before beginning any component service. This will disable the airbag system. Failure to disable the airbag system may result in accidental airbag deployment, personal injury, or death. Do not place an intact undeployed airbag face down on a solid surface.

The airbag will propel into the air if accidentally deployed and may result in personal injury or death. When carrying or handling an undeployed airbag, the trim side face of the airbag should be pointing towards the body to minimize possibility of injury if accidental deployment occurs. Failure to do this may result in personal injury or death. Replace 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. Wear 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. Back to Top irritation is experienced, exit the vehicle for fresh air until the irritation ceases.

If irritation continues, see a physician. Do 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. During, and following, any child restraint anchor service, due to impact event or vehicle repair, carefully inspect all mounting hardware, tether straps, and anchors for proper installation, operation, or damage.

If a child restraint anchor is found damaged in any way, the anchor must be replaced. Deployed and non-deployed airbags may or may not have live pyrotechnic material within the airbag inflator. Refer to the Hazardous Substance Control System for proper disposal.

Dispose of deployed airbags and tensioners consistent with state, provincial, local, and federal regulations. After any airbag component testing or service, do not connect the battery negative cable. Personal injury or death may result if the system test is not performed first. If the vehicle is equipped with the Occupant Classification System OCS , do not connect the battery negative cable before performing the OCS Verification Test using the scan tool and the appropriate diagnostic information.

Personal injury or death may result if the system test is not performed properly. If both require replacement, replace one, then perform the Airbag System test before replacing the other. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and cause personal injury or death. Do not drop or handle roughly.

If dropped or damaged, replace with another sensor. Failure to do so may result in occupant injury or death. 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. If equipped with OCS, when the passenger front seat is on the floor, no one should sit in the front passenger seat. This uneven force may damage the sensing ability of the seat weight sensors.

If sat on and damaged, the sensor may be inoperative, could result in occupant injury, or possibly death. The system must be disarmed before performing service on, or around, system components, the steering column, instrument panel components, wiring and sensors. Failure to follow the safety precautions and the disarming procedure could result in accidental air bag deployment, possible injury and unnecessary system repairs.
