Detach the bumper cover and disconnect any wiring or components that may interfere with the bumper removal, taking care not to damage the SIR system sensors if equipped; if the sensors are removed, ensure the SIR system is disarmed first, and when reinstalling the sensors, tighten the mounting bolts to the specified torques before plugging them in and reactivating the system. Support the bumper with a jack or jackstand, or have an assistant hold it while removing the retaining bolts to detach the bumper. For installation, reverse the removal process, securely tighten the retaining bolts, and reinstall the bumper cover along with any other components that were taken off.
