If this procedure allows the engine to start, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices. KEY POSITIONS The switch includes an anti-theft steering lock device. LOCK (Normal parking position) (0) The ignition key can only be removed when the switch is in this position. OFF (1) The engine can be turned off without locking the steering wheel. The ignition lock is designed so that the key cannot be turned to LOCK and removed until the selector lever is moved to the P (Park) position. ACC (Accessories) (2) This position activates electrical accessories such as the radio when the engine is not running. NISSAN VEHICLE IMMOBILIZER SYSTEM The NISSAN Vehicle Immobilizer System will not allow the engine to start without the use of the registered key. If the engine fails to start using a registered key (for example, when interference is caused by another registered key, an automated toll road device or automated payment device on the key ring), restart the engine using the following procedures: 1. Leave the ignition switch in the ON position for approximately 5 seconds. 2. Turn the ignition switch to the OFF or LOCK position and wait approximately 10 seconds. 3. Repeat steps 1 and 2. 4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key. 5-8 Starting and driving
