Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly). CAUTION: The CHANGE BRAKE PADS message or the high-pitched warning sound means that soon your brakes won't work well. That could lead to an accident. When the CHANGE BRAKE PADS message comes on and stays on, have your vehicle serviced. CAUTION: The brake wear warning sound means that soon your brakes won't work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced. Your vehicle also has electronic wear sensors that let you know when the brake pads are significantly worn and new pads are needed. The CHANGE BRAKE PADS message will be displayed on the Driver Information Center when the brake pads are worn and need to be replaced. See "Change Brake Pads Message" in the Index. NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. 6-32
