Be sure to read the following before using the Intelligent Key system. ● When the Intelligent Key is placed near an electric appliance such as a personal computer. ● When the vehicle is parked near a parking meter. In such cases, correct the operating conditions before using the Intelligent Key function or use the mechanical key. Although the life of the battery varies depending on the operating conditions, the battery's life is approximately 2 years. If the battery is discharged, replace it with a new one. Since the Intelligent Key is continuously receiving radio waves, if the key is left near equipment which transmits strong radio waves, such as signals from a TV and personal computer, the battery life may become shorter. For information regarding replacement of a battery, see "INTELLIGENT KEY BATTERY REPLACEMENT" in the "8. Maintenance and do-ityourself" section. Because the steering wheel is locked electrically, unlocking the steering wheel with the ignition switch in the LOCK position is impossible when the vehicle battery is completely discharged. Pay special attention that the vehicle battery is not completely discharged. CAUTION ● Be sure to carry the Intelligent Key with you when operating the vehicle. ● Never leave the Intelligent Key in the vehicle when you leave the vehicle. The Intelligent Key is always communicating with the vehicle as it receives radio waves. The Intelligent Key system transmits weak radio waves. Environmental conditions may interfere with the operation of the Intelligent Key system under the following operating conditions. ● When operating near a location where strong radio waves are transmitted, such as a TV tower, power station and broadcasting station. ● When in possession of wireless equipment, such as a cellular telephone, transceiver, and CB radio. ● When the Intelligent Key is in contact with or covered by metallic materials. ● When any type of radio wave remote control is used nearby. As many as 4 Intelligent Keys can be registered and used with one vehicle. For information about the purchase and use of additional Intelligent Keys, contact an INFINITI retailer. CAUTION ● Do not allow the Intelligent Key, which contains electrical components, to come into contact with water or salt water. This could affect the system function. ● Do not drop the Intelligent Key. ● Do not strike the Intelligent Key sharply against another object. ● Do not change or modify the Intelligent Key. ● Wetting may damage the Intelligent Key. If the Intelligent Key gets wet, immediately wipe until it is completely dry. ● Do not place the Intelligent Key for an extended period in an area where temperatures exceed 140°F (60°C). ● Do not attach the Intelligent Key with a key holder that contains a magnet. ● Do not place the Intelligent Key near equipment that produces a magnetic field, such as a TV, audio equipment and personal computers.
