If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
•
Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
We recommend Motorcraft® motor oil for
your vehicle. If Motorcraft® oil is not
available, use motor oils of the
recommended viscosity grade that meet
API SN requirements and display the API
Certification Mark for gasoline engines. Do
not use oil labeled with API SN service
category unless the label also displays the
API certification mark. An oil that displays this symbol conforms
to current engine, emission system and
fuel economy performance standards of
ILSAC.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.
Note:
Ford recommends using DOT 4 Low
Viscosity (LV) 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.
Note: Automatic transmissions that require
MERCON® LV transmission fluid should
only use MERCON® LV transmission fluid.
The use of any other fluid may cause
transmission damage.
Alternative Engine Oil for
Extremely Cold Climates
To improve engine cold start performance,
we recommend that you use the following
alternative engine oil in extremely cold
climates, where the ambient temperature
reaches -22.0°F (-30°C) or below.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when
you sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you
have your vehicle serviced at the proper
times. These intervals serve two purposes;
one is to maintain the reliability of your
vehicle and the second is to keep your cost
of owning your vehicle down.
It is your responsibility to have all
scheduled maintenance performed and to
make sure that the materials used meet
the specifications identified in this owner's
manual. See Capacities and
Specifications (page 302).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the
operation of your vehicle. Ask your
dealership about the training and
certification their technicians have
received. Genuine Ford and Motorcraft®
Replacement Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed
at your dealership carry a nationwide
24-month or unlimited mile (kilometer)
parts and labor limited warranty.
If you do not use Ford authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one
stop shopping. They can perform any
services that are required on your vehicle,
from general maintenance to collision
repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved
reliability, durability and resale value. To
maintain the proper performance of your
vehicle and its emission control systems,
make sure you have scheduled
maintenance performed at the designated
intervals.
Your vehicle is equipped with the
Intelligent Oil-Life Monitor system, which
displays a message in the information
display at the proper oil change interval.
This interval may be up to one year or
10,000 mi (16,000 km)
