Remove the air filter element from the
air filter housing.
6. Remove the foam filter from the air filter housing.
7. Install in the reverse order. Air Filter Restriction Gauge
The air filter restriction gauge is in the
upper housing of the air filter assembly.
Check the air filter restriction gauge
whenever you open the hood to carry out
general engine maintenance or at least
every 7,500 mi (12,000 km). If you operate
your vehicle in extremely dusty conditions,
check the gauge at least every 500 mi
(800 km) or two weeks, whichever occurs
first. Change the air filter element when
the restriction gauge reads near the
change filter line and the gauge is yellow.
Allowing the restriction gauge to reach
maximum affects engine performance and
fuel economy.

Operating your vehicle in heavy snowfall
or extreme rain conditions may allow
excessive amounts of snow or water into
the air intake system. This could restrict air
flow and cause the engine to lose power
or shut down.
After installing a new air filter element, you
must reset the gauge by pressing the reset
button.
After operating your vehicle during heavy
snowfall or extreme rain, do the following:
•
Snow: At the earliest opportunity, open
the hood and clear any snow and ice
from the air filter housing inlet and
reset the air filter restriction gauge.
• Extreme rain: The air filter element
dries out after approximately 15– 30
minutes of driving at highway speeds.
At the earliest opportunity, open the
hood and reset the air filter restriction
gauge.
Note: Do not remove the foam filter.
CHANGING THE ENGINE-
MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS - 6.7L DIESEL WARNING
Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is attached to the fuel tank in
different locations depending on the
configuration of your truck. See table
below for configurations.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See Scheduled
Maintenance (page 581).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 422).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

REPAIRING MINOR PAINT
DAMAGE
Authorized dealers have touch-up paint to
match your vehicle
’s color. Your vehicle
color code is printed on a sticker on the
front, left-hand side door jamb. Take your
color code to your authorized dealer to
make sure you get the correct color.
Before repairing minor paint damage, use
a cleaner such as Motorcraft Bug and Tar
Remover to remove particles such as bird
droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout.
Always read the instructions before using
cleaning products.
CLEANING THE WHEELS (If
Equipped)
1. Regularly clean them with a wheel cleaner. We recommend that you use
Ford approved wheel cleaner if
available.
2. Remove dirt and brake dust with a sponge.
3. Remove tar and grease with a bug and
tar remover. We recommend that you
use Ford approved bug and tar remover
if available.
4. Thoroughly rinse the wheels with water
after cleaning.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before doing so. This
reduces the risk of corrosion of the brake
discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers. Note:
Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers.
VEHICLE STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all motor vehicles
and their components for reliable, regular
driving. Under various conditions,
long-term storage may lead to degraded
engine performance or failure unless you
use specific precautions to preserve engine
components.
General
• Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.

You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. Ford
recommends the use of a digital
or dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
WARNING
Under-inflation is the most
common cause of tire failures
and may result in severe tire
cracking, tread separation or
blowout, with unexpected loss of
vehicle control and increased risk
of injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat! Always inflate your tires to the
Ford recommended inflation
pressure even if it is less than the
maximum inflation pressure
information found on the tire. The
Ford recommended tire inflation
pressure is found on the Safety
Compliance Certification Label or Tire Label (affixed to either the
door hinge pillar, door-latch post,
or the door edge that meets the
door-latch post, next to the
driver's seating position), or Tire
Label located on the B-pillar or
the edge of the driver's door.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles.
Note:
Do not reduce tire pressure
to change the ride characteristics
of the vehicle. If you do not
maintain the inflation pressure at
the levels specified by Ford, your
vehicle may experience a condition
known as shimmy. Shimmy is a
severe vibration and oscillation in
the steering wheel after the vehicle
travels over a bump or dip in the
road that does not dampen out by
itself. Shimmy may result from
significant under-inflation of the
tires, improper tires (load range,
size, or type), or vehicle
modifications such as lift-kits. In
the event that your vehicle
experiences shimmy, you should
slowly reduce speed by either lifting
off the accelerator pedal or lightly
applying the brakes. The shimmy
will cease as the vehicle speed
decreases.
Maximum Inflation Pressure is
the tire manufacturer's maximum
permissible pressure and the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
390

Inspecting Your Tires and
Wheel Valve Stems
Periodically inspect the tire treads
for uneven or excessive wear and
remove objects such as stones,
nails or glass that may be wedged
in the tread grooves. Check the tire
and valve stems for holes, cracks,
or cuts that may permit air
leakage and repair or replace the
tire and replace the valve stem.
Inspect the tire sidewalls for
cracking, cuts, bruises and other
signs of damage or excessive
wear. If internal damage to the tire
is suspected, have the tire
demounted and inspected in case
it needs to be repaired or replaced.
For your safety, tires that are
damaged or show signs of
excessive wear should not be used
because they are more likely to
blow out or fail.
Improper or inadequate vehicle
maintenance can cause tires to
wear abnormally. Inspect all your
tires, including the spare,
frequently, and replace them if
one or more of the following
conditions exist:
