Important ventilating information If the engine is idling while the vehicle is stopped for a long period of time, open the windows at least one inch (2.5 cm) or adjust the heating or air conditioning to bring in fresh air. BRAKES Your service brakes are self-adjusting. Refer to the scheduled maintenance guide for scheduled maintenance. Occasional brake noise is normal and often does not indicate a performance concern with the vehicle's brake system. In normal operation, automotive brake systems may emit occasional or intermittent squeal or groan noises when the brakes are applied. Such noises are usually heard during the first few brake applications in the morning; however, they may be heard at any time while braking and can be aggravated by environmental conditions such as cold, heat, moisture, road dust, salt or mud. If a "metal-to-metal," "continuous grinding" or "continuous squeal" sound is present while braking, the brake linings may be worn-out and should be inspected by a qualified service technician. Refer to Brake system warning light in the Instrument Cluster ! chapter for information on the brake BRAKE system warning light. 127 2004 Grand Marquis (grn) Owners Guide (post-2002-fmt) USA English (fus)
