Vehicle Service and Care Required Services" in the Limited Warranty, Maintenance and Owner Assistance Information manual. Use new brake fluid from a sealed container only. See "Recommended Fluids and Lubricants" in the Limited Warranty, Maintenance and Owner Assistance Information manual. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir. Notice: 9-23 Brake Wear Your vehicle has disc brakes. Notice: Continuing to drive with worn-out brake pads could result in costly brake repair. Front disc brake pads have built-in brake pad wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal firmly. • Using the wrong fluid can badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid. • If you spill brake fluid on your vehicle's painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See Exterior Cleaning on page 9-75. { CAUTION With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid. { CAUTION The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.
