RWARNING Exhaust leaks may result in the entry of harmful and potentially lethal fumes into the passenger compartment. Under extreme conditions excessive exhaust temperatures could damage the fuel system, the interior floor covering, or other vehicle components, possibly causing a fire. The Scheduled Maintenance Services listed in the Maintenance Schedule and Record booklet are required because they are considered essential to the life and performance of your vehicle and to its emissions system. Watch for fluid leaks, strange odors, smoke and loss of oil pressure. Also watch for the charge warning light, the check engine light, or the temperature warning light. These sometimes indicate that the emission system is not working properly. Do not make any unauthorized changes to your vehicle or engine. Changes that cause more unburned fuel to reach the exhaust system can increase the temperature of the engine or exhaust system. By law, anyone who manufactures, repairs, services, sells, leases vehicles, trades vehicles, or supervises a fleet of vehicles is not permitted to intentionally remove an emission control device or prevent it from working. In some of the United States and in Canada, vehicle owners may be liable if their emission control device is removed or is prevented from working. In general, maintenance, replacement, or service of the emission control devices or systems in your new Ford Motor Company vehicle or engine may be performed at your expense by any automotive repair establishment or individual using automotive parts equivalent to those with which your vehicle or engine was originally equipped. 360
