Accessories and Modifications Modifying your vehicle, or installing some non-Honda accessories, can make it unsafe. Before you make any modifications or add any accessories, be sure to read the following information. Accessories Your dealer has Honda accessories that allow you to personalize your vehicle, or improve its performance. These accessories have been designed and approved for your vehicle, and are covered by warranty. Although non-Honda accessories may fit on your vehicle, they may not meet factory specifications, and could adversely affect your vehicle's handling and stability. Before installing any accessory: Improper accessories or modifications can affect your vehicle's handling, stability, and performance, and cause a crash in which you can be hurt or killed. Follow all instructions in this owner's manual regarding accessories and modifications. When properly installed, cellular phones, alarms, two-way radios, and low-powered audio systems should not interfere with your vehicle's computer controlled systems, such as your airbags and anti-lock brakes. Make sure the accessory does not obscure any lights, or interfere with proper vehicle operation or performance. Be sure electronic accessories do not overload electrical circuits (see page 204 ) or interfere with proper operation. Before installing any electronic accessory, have the installer contact your dealer for assistance. If possible, have your dealer inspect the final installation. 128
