General maintenance information

GENERAL MAINTENANCE INFORMATION

This Service Guide indicates the scheduled maintenance required for your vehicle. Proper maintenance guards against major repair expenses resulting from neglect or inadequate maintenance, and may help increase the value you receive when you sell or trade your vehicle.

It is your responsibility to make sure that all of the scheduled maintenance is performed and that the materials used meet Ford engineering specifications. Failure to perform scheduled maintenance, as specified in the Service Guide, will invalidate warranty coverage on parts affected by the lack of maintenance. Make sure that receipts for completed maintenance work are retained with the vehicle and confirmation of maintenance work is always entered in your Service Guide.

Your Ford or Lincoln-Mercury dealership, or Ford or Lincoln-Mercury Auto Care service center, has factory-trained technicians who can perform the required maintenance using genuine Ford parts. The dealership looks forward to meeting your every service need to maximize your satisfaction with your vehicle.

Maintenance: An investment

Maintenance is an investment that 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, the 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 Guide” for complete warranty information.

NO COST PCV VALVE REPLACEMENT

The PCV valve is a critical emission component. Your dealer will replace the valve at no cost at 96,000 kilometers (60,000 miles), except in Canada and California.
