   • 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.
