Using this arm rest extension is easy. First, make sure your vehicle is turned off. Remove any items from your current center console. Then, take the arm rest extension and align it with your factory center console. You'll find that it fits right in without the need to drill or trim. Use the provided installation hardware and follow the instructions to secure it in place. Once installed, you can start enjoying the extra height and storage. As for maintenance, simply use a soft, damp cloth to clean the arm rest. Avoid using harsh chemicals as they might damage the charcoal gray finish. And remember, this product is only for manual transmission models, so don't try to install it on a CVT model.
