1. Move the shift selector lever into the P (Park) position. 2. Turn the ignition switch slightly in the ON direction. 3. Turn the key toward the LOCK position. The shift selector lever can be moved from the P (Park) position if the ignition switch is in the ON position and the foot brake pedal is depressed. There is an OFF position in between LOCK and ACC, although it does not show on the lock cylinder. When the ignition is in OFF the steering wheel is not locked. In order for the steering wheel to be locked, it must be turned about 1/6 of a turn counterclockwise from the straight up position. To lock the steering wheel, turn the ignition switch to the LOCK position. To unlock the steering wheel, push the ignition switch in and turn it gently while rotating the steering wheel slightly right and left. If the battery of the vehicle equipped with the Intelligent Key system is discharged, the ignition switch cannot be turned from the LOCK position, even using the mechanical key. IGNITION SWITCH POSITIONS Push in the ignition switch to the B position when you turn it. LOCK (Normal parking position) A : The ignition switch can only be locked in the LOCK position. The ignition switch will be unlocked when it is pushed in, and turned to the ACC position C while carrying the Intelligent Key. ACC (Accessories) C : This position activates electrical accessories such as the radio, when the engine is not running. ON (Normal operating position) D : This position turns on the ignition system and the electrical accessories. START E : This position starts the engine. As soon as the engine has started, release the knob immediately. It will automatically return to the ON position. The ignition switch cannot be turned back to the LOCK position unless the selector lever is in the P (Park) position. (It can be turned only to the B position.) CAUTION Do not leave the vehicle with the ignition switch in ACC or ON positions when the engine is not running for an extended period. This can discharge the battery. INFINITI VEHICLE IMMOBILIZER SYSTEM The INFINITI Vehicle Immobilizer System will not allow the engine to start without the use of the registered key. If the engine fails to start using the registered key, it may be due to interference 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 5 seconds. 3. Repeat step 1 and 2 again. 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, INFINITI recommends placing the registered key on a separate key ring to avoid interference from other devices. Starting and driving 5-9
