Nissan is conducting a voluntary safety recall on model year 2003 – 2007 Murano vehicles. Under certain conditions, the intake duct, which is connected to the intermediate resonator in the air intake system of the engine, may separate from the resonator with engine movement. This could cause minor idle fluctuation or poor acceleration. If this occurs, and the vehicle continues to be driven without being serviced, the engine may stall while driving. To remedy this potential condition, Nissan is conducting this voluntary safety recall campaign to replace the air intake duct with an updated part and the air duct clamps with new clamps at no charge for parts or labor. SERVICE PROCEDURE CAUTION: Do not use any lubricant when removing or installing the air ducts and resonators. Lubricant may adversely affect the ducts and resonators. 1. Disconnect the Positive Crankcase Ventilation (PCV) hose from resonator 1. 2. Loosen the clamps shown in Figure 1 (clamps at both ends of the air duct assembly). 3. Remove the air duct assembly from the vehicle and set it on a clean working surface. 4. After removing the air duct assembly, cover the openings to the electronic control throttle and airflow meter with clean cloth / rags. CAUTION: • Make sure to cover the openings to the electronic control throttle and airflow meter. • Covering the openings will prevent debris entry. 5. Loosen both wire clamps shown in Figure 2 (clamps on both sides of resonator 1). 6. Replace the wire clamp on air duct B. a. Pull air duct B away from resonator 1 just enough to remove the old wire clamp and install a new one. • Bend the old wire clamp so it cannot be reused. b. Reconnect air duct B to resonator 1. CAUTION: Before installing air duct B, use a clean cloth / rag to wipe away any debris from the duct and resonator.

CONDITION 4 wheel drive mode inoperative (diagnosed either during or after replacing knuckles and hub seals) due to insufficient vacuum being applied to the hubs. CAUSE In some cases moisture has entered the vacuum system, and vacuum lines have become corroded, plugged, or have developed a leak. CORRECTIVE ACTION Verify that with 4 wheel drive mode selected, vacuum is present at the T-fitting downstream from the solenoid (see photo). If not, diagnose and repair as required, otherwise use the following procedure to replace the vacuum lines: Note: Procedure applies to right side line; left side needs no further info. Disconnect and remove battery and battery tray. Leaving ground cables attached, remove clamp bracket from battery tray bottom and move out of the way. Remove plastic air resonator and disconnect throttle cable (plus A/T control cable if equipped). Disconnect MAF and IAC connectors, and 6 mm bolt holding DLC and MAF brackets to air cleaner housing. Disconnect air intake tube from throttle body, and MAF sensor from air
