Accessories and Modifications

When installing accessories, check the following:

Do not install accessories on the windshield. They can obstruct your view and delay your reaction to driving conditions.

Do not install any accessories over areas marked SRS AIRBAG, on the sides or backs of the front seats, on front or side pillars, or near the side windows. Accessories installed in these areas may interfere with proper operation of the vehicle’s airbags or may be propelled into you or another occupant if the airbags deploy.

Be sure electronic accessories do not overload electrical circuits or interfere with proper operation of your vehicle.

Before installing any electronic accessory, have the installer contact a dealer for assistance. If possible, have a dealer inspect the final installation.

Do not modify your vehicle in a manner that may affect its handling, stability, or reliability, or install non-genuine Honda parts or accessories that may have a similar effect.

Even minor modifications to vehicle systems can affect overall vehicle performance. Always make sure all equipment is properly installed and maintained, and do not make any modification to your vehicle or its systems that might cause your vehicle to no longer meet federal, state, province, territory, and local regulations.
