Do not drive with your foot resting on the brake pedal; you will wear out the linings and increase your vehicle's stopping distance. Brake rotor damage may also eventually occur. NOTE: If you are driving down a long or steep hill, shift to a lower gear and do not apply your brakes continuously. If you apply your brakes continuously, they may overheat and become less effective. Occasional brake squeal during light to moderate stops does not affect the function of the brake system and is normal. However, if the squeal becomes louder or more frequent, have your brakes inspected by your dealer or a qualified service technician. Ford Motor Company has not found any detrimental effects of popular mobile radio transmitting equipment installed on vehicles with the anti-lock brake system, if the equipment is installed according to the manufacturer's instructions. However, if mobile radio transmitting equipment is installed in your vehicle and, if either the anti-lock brake system cycles or the check anti-lock light comes on at any time other than right after you turn the key to ON or during a sudden stop, have your mobile radio dealer inspect the installation. 158
