KEY POSITIONS LOCK: Normal parking position (0) OFF: (Not used) (1) ACC: (Accessories) (2) This position activates electrical accessories such as the radio when the engine is not running. ON: Normal operating position (3) This position turns on the ignition system and the electrical accessories. START: (4) WSD0052 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 automatic payment device on the key ring), restart the engine using the following procedure: 1. Leave the ignition switch in the ON position for approximately 5 seconds. 2. Place the ignition switch in 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. If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices. MANUAL TRANSMISSION (if so equipped) The ignition switch includes a device that helps prevent accidental removal of the key while driving. The key can only be removed when the ignition switch is in the LOCK position. On manual transmission models, to turn the ignition switch to the LOCK position from the ACC or ON position, place the ignition switch in the OFF position, push the key in, then place the ignition switch in LOCK position. This position starts the engine. As soon as the engine has started, release the key. It automatically returns to the ON position. NISSAN VEHICLE IMMOBILIZER SYSTEM The NISSAN Vehicle Immobilizer system will not allow the engine to start without the use of the registered key. Starting and driving 5-11
