There is an OFF position between the LOCK and ON positions. The OFF position is indicated by a "1" on the ignition switch. For models without NISSAN vehicle immobilizer system: when the ignition switch is in the OFF position, the steering wheel is not locked. In order for the steering wheel to be locked, it must be turned about 1/8 of a turn clockwise from the straight up position. To lock the steering wheel, turn the ignition to the LOCK position. Remove the key. To unlock the steering wheel, insert the key and turn it gently while rotating the steering wheel slightly right and left. If the key will not turn from the LOCK position, turn the steering wheel to the left or right while turning the key to unlock the key cylinder. This position turns on the ignition system and the electrical accessories. START: (4) This position starts the engine. As soon as the engine has started, release the key. It automatically returns to the ON position. If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices. 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 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.
