BEFORE STARTING THE ENGINE NISSAN VEHICLE IMMOBILIZER SYSTEM (NVIS) The NISSAN Vehicle Immobilizer System (NVIS) will not allow the engine to start without the use of the registered NVIS key. If the engine fails to start using the registered NVIS key, it may be due to interference caused by another NVIS 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 NVIS key. If this procedure allows the engine to start, NISSAN recommends placing the registered NVIS key on a separate key ring to avoid interference from other devices. ● Make sure the area around the vehicle is clear. ● Check fluid levels such as engine oil, coolant, brake fluid, and window washer fluid as frequently as possible, or at least whenever you refuel. ● Check that all windows and lights are clean. ● Visually inspect tires for their appearance and condition. Also check tires for proper inflation. ● Lock all doors. ● Position seat and adjust head restraints. ● Adjust inside and outside mirrors. ● Fasten seat belts and ask all passengers to do likewise. ● Check the operation of warning lights when the key is turned to the ON (3) position. See "Warning/indicator lights and audible reminders" in the "Instruments and controls" section of this manual. WARNING Never remove or turn the key to the LOCK position while driving. The steering wheel will lock. This may cause the driver to lose control of the vehicle and could result in serious vehicle damage or personal injury.
