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 335).
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 an intelligent
oil-life monitor that determines oil life
based on engine operating conditions.

•
Under normal operating conditions, a
message appears in the information
display to indicate the regular oil
change interval.
• Under severe operating conditions, the
oil change interval may reduce, and the
message interval may adjust.
High performance vehicles can be driven
in such a way that may lead to higher oil
consumption (this includes extended time
at high engine speeds, high loads, engine
braking, hard cornering maneuvers, and
track use). Under these conditions, oil
consumption of approximately 1 quart per
500 miles (1 liter per 800 km) is possible.
As a result, the engine oil level needs to be
checked at every refueling and adjusted to
maintain proper level to avoid engine
damage.
Note: Oil level should not exceed the
maximum mark on the indicator. See
Engine Oil Check (page 261).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or
500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 261).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) 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.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
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, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
