1Ford recommends using Motorcraft (Ford) DOT 4 Low Viscosity High Performance Brake Fluid or
equivalent meeting WSS-M6C65-A2. Use of any fluid other than the recommended fluid may cause
degraded brake performance and not meet the Ford performance standards. Keep brake fluid clean
and dry. Contamination with dirt, water, petroleum products or other materials may result in brake
system damage and possible failure.2Approximate dry fill capacity. Actual amount may vary during fluid changes.3Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid other
than the recommended fluid may cause transmission damage.4See your authorized dealer for fluid level checking or filling.5Your engine has been designed to use Motorcraft engine oils or equivalent oils that meet Ford
specifications. It is also acceptable to use an engine oil of recommended viscosity grade that meets
API SN requirements and displays the API Certification Mark for gasoline engines.6Do not use supplemental engine oil additives in your engine. They are unnecessary and could lead to
engine damage that is not covered by your Ford warranty.

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 equipped with the Intelligent Oil-Life Monitor (IOLM)
system which displays a message in the information display at the proper
oil change service interval; this interval may be up to one year or
10000 miles (16000 kilometers). When ENGINE OIL CHANGE DUE or
OIL CHANGE REQUIRED appears in the information display, it is time
for an oil change; the oil change must be done within two weeks or
500 miles (800 kilometers) of the ENGINE OIL CHANGE DUE or OIL
CHANGE REQUIRED message appearing. The Intelligent Oil-Life Monitor
must be reset after each oil change; see theInformation Displays
chapter.
If your information display is prematurely reset or becomes inoperative,
you should perform the oil change interval at six months or 5000 miles
(8000 kilometers) from your last oil change. Never exceed one year or
10000 miles (16000 kilometers) between oil change 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 is why it is
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 only genuine Ford, Motorcraft or
Ford-authorized remanufactured replacement parts because they are
engineered for your vehicle.
Additives and Chemicals
Ford Motor Company recommended additives and chemicals are listed in
the owner manual and in the Ford Workshop Manual. Additional
chemicals or additives not approved by Ford Motor Company are not
recommended as part of normal maintenance. Please consult your
warranty information.
