minutes of driving at highway speeds.
At the earliest opportunity, open the
hood and reset the air filter restriction
gauge.
CHANGING THE ENGINE AIR
FILTER - DIESEL WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.

service interval. See
Scheduled
Maintenance (page 664).
Use the correct specification air filter
element. See
Motorcraft Parts (page
581).
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty. 1. Release the clips that secure the air
filter housing cover. Lift and rotate the

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.
It is important that you have your vehicle
serviced at the proper times. These
intervals serve two purposes: first is to
maintain the reliability of your vehicle and
the second is to keep the 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 574).
Failure to perform scheduled maintenance
and regularly inspect your vehicle may
result in vehicle damage not covered by
the vehicle Warranty.
Why Maintain Your Vehicle at Your
Dealership?
Our Genuine Replacement Parts
Dealerships stock our parts and our
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 our authorized parts they
may not meet our specifications and could
affect emissions compliance. 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 comes with the Intelligent
Oil-Life Monitor system, a message
appears 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), hybrid vehicles could exceed
10,000 mi (16,000 km).
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 to reset the Intelligent Oil-Life Monitor
after each oil change. See
Resetting the
Engine Oil Change Reminder (page 511).
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.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption including extended time at
high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. Check the engine
oil level at every refueling and adjust to
maintain proper levels to avoid engine
damage.
