NISSAN INTELLIGENT KEY™ WITHOUT DOOR AND TRUNK REQUEST SWITCHES WARNING ● Radio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use. ● The Intelligent Key transmits radio waves when the buttons are pressed. The FAA advises the radio waves may affect aircraft navigation and communication systems. Do not operate the Intelligent Key while on an airplane. Make sure the buttons are not operated unintentionally when the unit is stored for a flight. The Intelligent Key can operate all the door locks using the remote controller function. The operating environment and/or conditions may affect the Intelligent Key operation. Be sure to read the following before using the Intelligent Key. The Intelligent Key is always communicating with the vehicle as it receives radio waves. The Intelligent Key transmits weak radio waves. Environmental conditions may interfere with the operation of the Intelligent Key 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. ● 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. When the Intelligent Key battery is almost discharged, insert the Intelligent Key into the Intelligent Key port to start the engine. Replace the discharged battery with a new one as soon as possible. For more details, see "Push-button ignition switch" in the "Starting and driving" section. 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 "Battery replacement" in the "Maintenance and do-it-yourself" section. 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 a NISSAN dealer. 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. Pre-driving checks and adjustments 3-17
