DESCRIPTION AND OPERATION

Scheduled Maintenance — Emissions

 CAUTION: To ensure the durability of the vehicle and its emission control systems, it is necessary that scheduled maintenance be performed at the designated intervals.

 CAUTION: Ford recommends the use of genuine Ford replacement parts. The maintenance, replacement, or repair of the emissions control devices and systems (the cost of which is not covered by warranty) may be performed by any automotive repair establishment or individual and may use other than Ford service parts for such maintenance or repair. If other than Ford or Motorcraft parts or Ford authorized remanufactured parts are used for maintenance replacements or the service of components affecting emissions control, the owner should assure himself that such parts are warranted by their manufacturer to be equivalent to genuine Ford Motor Company parts in performance and durability. Please consult the warranty booklet for complete warranty information.

The required maintenance schedules appearing on the following pages list the items required to maintain the vehicle emission systems at intervals determined by the federal government (Environmental Protection Agency).

Refer to the appropriate sections of the Powertrain Control/Emissions Diagnosis Manual OBDI or OBDII for the maintenance procedures that relate to the items listed in the maintenance schedules. Use these procedures to perform the required emission system maintenance items listed in the maintenance schedules.

NOTE: The PCV valve is a critical emissions component. The dealer will replace the valve at no cost at 60,000 miles (96,000 kilometers) (except Canada and California vehicles).

For vehicles with 7.5L engines, the dealer will replace the PCV valve at no cost at 60,000 miles (96,000 kilometers) (except Canada vehicles).

Any modification of the emission control systems could create liability under federal law (U.S.) if made prior to the first sale and registration, and under the laws of some states if made thereafter. Further, federal law prohibits vehicle manufacturers, dealers and other persons engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles as well as fleet operations from knowingly removing or rendering an emission control system inoperative after sale and delivery to an ultimate purchaser. In Canada, modifications of the emission control system could create liability under applicable federal or provincial laws.
