Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Installation Procedure
Be careful when you handle a sensor. Do not strike or jolt a sensor. Before applying power to a sensor:
- Remove any dirt, grease, etc. from the mounting surface.
- Position the sensor horizontally on the mounting surface.
- Point the arrow on the sensor toward the front of the vehicle.
- Tighten all of the sensor fasteners and sensor bracket fasteners to the specified torque value.
Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.
- Install the inflatable restraint front end discriminating sensor to the front end lower tie surface. Make sure the arrow is pointing toward the front of the vehicle.
- Refer to Fastener Notice
in Cautions and Notices.
