GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for 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 ensure 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™ system
which displays a message in the message at the proper oil change service
interval; this interval may be up to one year or 10,000 miles (16,000 km).
When ENGINE OIL CHANGE DUE or OIL CHANGE REQUIRED appears
in the message center display, it’s time for an oil change; the oil change
must be done within two weeks or 500 miles (800 km) of the ENGINE
OIL CHANGE DUE or OIL CHANGE REQUIRED message appearing. The
Intelligent Oil Life Monitor™ must be reset after each oil change; refer to
theInstrument Clusterchapter.
If your message center is prematurely reset or becomes inoperative, you
should perform the oil change interval at six months or 5,000 miles
(8,000 km) from your last oil change.

NORMAL SCHEDULED MAINTENANCE AND LOG
Intelligent Oil Life Monitor™
Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
determines when the engine oil should be changed based on how your
vehicles is used. By using several important factors in its calculations,
the monitor helps reduce the cost of owning your vehicle and reduce
environmental waste at the same time. This means you won’t have to
remember to change the oil on a mileage-based schedule; the vehicle lets
you know when an oil change is due by displaying ENGINE OIL
CHANGE DUE or OIL CHANGE REQUIRED in the message center. The
following table is intended to provide examples of vehicle use and its
impact on engine oil change intervals; it is provided as a guideline only.
Actual engine oil change intervals will depend on several factors and will
generally decrease with severity of use.

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed below:
Normal vehicle axle maintenance:Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3,000 miles (4,800 km) or three months, whichever
comes first. This interval can be waived if the axle is filled with 75W140
synthetic gear fluid meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles (refer toMaintenance product specifications and capacitiesin
theMaintenance and Specificationschapter for details).
Police/Taxi/Livery vehicle axle maintenance:Change rear axle fluid
every 100,000 miles (160,000 km). Rear axle fluid change may be waived if
the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent. Add
four ounces (118 mL) of additive friction modifier XL-3 (EST-M2C118-A) or
equivalent for complete refill of Traction-Lok rear axles. The axle fluid
should be changed anytime the axle has been submerged in water
California fuel filter replacement:If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the vehicle’s
useful life. Ford Motor Company, however, urges you to have all
recommended maintenance services performed at the specified intervals
and to record all vehicle service.
Class A Motorhome:Change brake fluid every two years.
Hot climate oil change intervals:If operating conditions are normal
and you drive your vehicle under typical, everyday conditionsandyou
are using an API performance category oil of SL or later (for example
SM, etc.) then you can follow the 7,500 mile (12,000 km) normal service
oil change intervals schedule. Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or locations with similar climates must
follow the oil change interval of 3,000 mile (4,800 km) if the owner is
using oils defined by the American Petroleum Institute (API)
performance category of API SK or earlier (for example SJ, etc).
