The following are VERY IMPORTANT to prevent unexpected air bag deployment.
^ Remove the ignition key / Intelligent Key from the cabin of the vehicle and set aside, away from the vehicle (this will prevent accidentally turning the ignition ON).
^ Make sure the ignition remains OFF until after the new sensor is completely installed.
^ Make sure no one is in the vehicle cabin and no one enters the vehicle cabin until after the sensor is completely installed.
^ Wait for all control units to "power down" (at least 1 minute) before continuing.
