OWNER S LETTER Dear Nissan Owner: Nissan is committed to providing the highest levels of product quality and customer satisfaction. The AudioPilot noise compensation feature of the Bose audio system installed in your 350Z Touring Model uses a microphone to detect external road noise and automatically adjusts the sound system equalization to compensate for this. Some customers of these vehicles have reported that the noise compensation feature causes the volume and bass to go up and down unexpectedly or that it causes the volume and bass to be exaggerated or excessive at times. WHAT NISSAN WILL DO To ensure satisfaction with your audio system, Nissan, in cooperation with Bose, has launched a Customer Satisfaction Initiative to replace the amplifier with one having an improved noise compensation feature that is more balanced with less noticeable change in the volume and bass. WHAT YOU CAN DO Many of our customers are pleased with the quality and performance of their Bose audio system. If this describes you, no further action is necessary. However, if you would like to have a new amplifier with a more balanced noise compensation feature with less noticeable change in the volume and bass installed in your vehicle, please contact your Nissan dealer at your earliest convenience and schedule an appointment. This free service should take about 2 hours to complete, based upon the dealer s work schedule. Please bring this notice with you to your service appointment. Nissan representatives are available at 800-NISSAN1 (800-647-7261) to address any questions or concerns you may have. If you reside in Hawaii, please call (808) 836-0888. Thank you for the opportunity to ensure continued customer satisfaction with your Nissan 350Z. Sincerely, Mark C. McNabb Vice President and General Manager Nissan Division 11/11
