VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is printed on the Vehicle Rating Decal attached to the vehicle
on the edge of the driver’s door or B-Pillar. The VIN also serves as the
warranty number. If you ever find it necessary to communicate with Ford
Motor Company about your vehicle, always include the VIN in your
communication.

WHY MAINTAIN YOUR VEHICLE?
Carefully following this schedule helps protect against major repair
expenses resulting from neglect or inadequate maintenance and may also
help to increase the value of your vehicle when you sell or trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications as identified in theMaintenance and Specifications
chapter. Failure to perform scheduled maintenance specific in this guide
will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your dealer has factory-trained technicians who can perform the required
maintenance using genuine Ford parts. They are committed to meeting
your service needs and to assuring your continuing satisfaction.
Protecting Your Investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To maintain the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraftor Ford-authorized remanufactured
parts that are used for maintenance replacement or for the service of
components affecting emission control must 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 yourWarranty Guidefor complete warranty information.

Chemicals or additives not approved by Ford are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
OWNER CHECKS AND SERVICES
Certain basic maintenance checks and inspections should be performed
by the owner or a service technician at the intervals indicated. Service
information and supporting specifications are provided in this owner’s
guide.
Any adverse condition should be brought to the attention of your dealer
or qualified service technician as soon as possible for the proper service
advice. The owner maintenance service checks are generally not covered
by warranties so you may be charged for labor, parts or fluids used.
