1Ford recommends using Motorcraft (Ford) DOT 3 High Performance Motor Vehicle Brake Fluid
or equivalent meeting WSS-M6C65-A1. 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.2Add the coolant type originally equipped in your vehicle.3Use of synthetic or synthetic blend motor oil is not mandatory. Only use fluid that meets Ford
specification. Motor oils of the recommended viscosity grade that meet API SN requirements and
display the API Certification Mark for gasoline engines are also acceptable. Do not use oil labeled
with API SN service category unless the label also displays the API Certification Mark.
An oil that displays the API Certification Mark conforms to current engine, emission system and
fuel economy performance standards of the International Lubricant Standardization and Approval
Committee (ILSAC).
Do 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.4Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance information to determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size
and if equipped with an in-tank cooler.

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.
