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. ● Do not place the Intelligent Key near equipment that produces a magnetic field, such as a TV, audio equipment and personal computers. If an Intelligent Key is lost or stolen, NISSAN recommends erasing the ID code of that Intelligent Key from the vehicle. This may prevent the unauthorized use of the Intelligent Key to operate the vehicle. For information regarding the erasing procedure, contact a NISSAN dealer. HOW TO USE THE REMOTE KEYLESS ENTRY FUNCTION The remote keyless entry function can operate all door locks using the remote keyless function of the Intelligent Key. The remote keyless function can operate at a distance of 33 ft (10 m) away from the vehicle. The operating distance depends upon the conditions around the vehicle. The remote keyless entry function will not function under the following conditions: ● When the Intelligent Key is not within the operational range. ● When the doors or the trunk are open or not closed securely. ● When the Intelligent Key battery is discharged. 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.
