Maintenance: An investment An investment which will pay dividends in the form of improved reliability, durability, and resale value. To assure the durability of your vehicle and its emission control systems, it is necessary that scheduled maintenance be performed at the designated intervals. Ford strongly recommends the use of genuine Ford replacement parts. If other than Ford or Motorcraft parts or Ford authorized remanufactured parts are used for maintenance replacements or for the service of components affecting emission control, such non-Ford parts should be equivalent to genuine Ford Motor Company parts in performance and durability. It is the owner's responsibility to determine the equivalency of such parts. Please consult your warranty booklet for complete warranty information.
