CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle safety belts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
seat safety belts to make sure there are no
nicks, tears or cuts. Replace if necessary.
All vehicle safety belt assemblies, including
retractors, buckles, front safety belt buckle
assemblies, buckle support assemblies
(slide bar-if equipped), shoulder belt
height adjusters (if equipped), shoulder
belt guide on seat back (if equipped), child
safety seat LATCH and tether anchors, and
attaching hardware, should be inspected
after a crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint. Ford Motor Company recommends that
all safety belt assemblies in use in vehicles
involved in a crash be replaced. However,
if the crash was minor and an authorized
dealer finds that the belts do not show
damage and continue to operate properly,
they do not need to be replaced. Safety
belt assemblies not in use during a crash
should also be inspected and replaced if
either damage or improper operation is
noted.
Properly care for safety belts. See Vehicle
Care (page 225).
SEATBELT EXTENSION WARNINGS
Persons who fit into the vehicle's
seatbelt should not use an extension.
Unnecessary use could result in
serious personal injury in the event of a
crash. Only use extensions provided free of
charge by Ford Motor Company
dealers. The dealer will provide an
extension designed specifically for this
vehicle, model year and seating position.
The use of an extension intended for
another vehicle, model year or seating
position may not offer you the full
protection of your vehicle ’s seatbelt
restraint system. Never use seatbelt extensions to
install child restraints.
Do not use a seatbelt extension with
an inflatable seatbelt.
Do not use extensions to change the
fit of the belt across the torso, over
the lap or to make the seatbelt
buckle easier to reach. 36

AIR SUSPENSION (If Equipped)
Note: Do not operate your vehicle without
air in the suspension springs. Operating your
vehicle without air in the suspension springs
damages the suspension, degrades ride
performance and may cause property
damage.
The air suspension system automatically
adjusts to different loads to maintain a
constant frame height, allows for ease of
vehicle loading, provides improved vehicle
ride, and increased driver comfort.
Air Suspension Dump Button Note:
The suspension dumps air when the
ignition is in the accessory or on position,
but fills only when the ignition is in the on
position.
A button located on the instrument panel
controls the system. It operates only when
the ignition is in the accessory or on
position and the air tanks have sufficient
pressure to fill the air springs. When you
turn off the ignition, the suspension
remains in whatever state it was last set.
Pressing and holding the button for two
seconds exhausts air from the air springs,
lowering the frame for loading. Pressing
and holding the button for two seconds
fills the air springs so your vehicle remains
at normal ride height. System Indicator Light
The air suspension indicator light
illuminates when using the button to
release air pressure in the rear air springs.
Never drive your vehicle when the warning
lamp is illuminated and there is low (or no)
air pressure in the springs.
Connecting and Disconnecting a
Trailer with Air Suspension and Air
Suspension Dump Button
When connecting to a trailer:
•
Press and hold the button for two
seconds to exhaust air from the air
suspension system.
• Press and hold the button for two
seconds, and then raise the landing
gear after making the connection to
the trailer.
When disconnecting the trailer:
• Lower the landing gear, and then press
and hold the button for two seconds.
• Disconnect the brake hoses, trailer-side
and rear light connectors, then pull the
release lever on the fifth wheel.
You must fill the air springs before
operating with a trailer or operating in the
bobtail mode.
Suspension Conversions WARNING
When operating a loaded vehicle, the
driver must keep all adjustable axles
on the ground at all times, supporting
their share of the vehicle ’s load. Failure to
do so can overload other axles, tires,
wheels, springs, steering components,
brakes and frames, resulting in early
component failure, loss of vehicle control,
possible property damage and personal
injury. 136

Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters)
away.
2. Measure the height of the headlamp bulb center from the ground and mark
an 8 foot (2.4 meter) horizontal
reference line on the vertical wall or
screen at this height.
Note: To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Turn on the low beam headlamps to illuminate the wall or screen and open
the hood. 4. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted. 5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp.
6. Repeat steps 3 thru 5 to adjust the other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.

•
Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.
SUSPENSION SYSTEM
INSPECTION
Note: Do not adjust air suspension height
to any setting other than the specified
setting. Altering the height setting changes
the driveline angle and may result in
unwarrantable component damage, such
as transmission component damage.
Verify drive axle air suspension height and
height control valve performance at engine
oil change intervals.
Periodically check:
• Condition of spring leaves for evidence
of fatigue, bending or breakage.
• Condition of suspension mounting
brackets and bushings.
• Torque rod mounting fasteners for
tightness. •
For proper suspension alignment.
Maintain proper alignment at all times.
• U-bolts. After the chassis has been
operating under load for
1,000 mi
(1,600 km) or six months (whichever
comes first), the U-bolt nuts must be
re-torqued. Re-torque the U-bolt nuts
every
37,000 mi (60,000 km)
thereafter. Clean and lubricate the
U-bolt and nut threads and seats to
make sure a like new condition when
re-torqueing. See
Spring U-Bolt
Check (page 224).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufactured
with frame rails of either HSLA steel or
heat-treated steel. Handle each in a
specific manner to make sure maximum
service life. Consult the service manual or
an authorized dealer before attempting
frame repair or modification.
It is important, particularly on vehicles that
use tow hooks frequently, to inspect the
front and rear tow hooks for damage or a
loose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optional
synthetic lubricant that allows the use of
extended service intervals. A tag on the
filler plug identifies the use of the synthetic
lubricant.
Only use a lubricant that meets
manufacturer specifications. Only use a
lubricant that meets manufacturer
specifications. Use of a non-approved rear
axle lubricant may cause internal axle
component damage. See Capacities and
Specifications
(page 258).

Information on P Type Tires
P215/65R15 95H is an example of
a tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.) A.
P: Indicates a tire, designated
by the Tire and Rim Association,
that may be used for service on
cars, sport utility vehicles,
minivans and light trucks. Note:
If
your tire size does not begin with
a letter this may mean it is
designated by either the European
Tire and Rim Technical
Organization or the Japan Tire
Manufacturing Association.
B. 215:
Indicates the nominal
width of the tire in millimeters
from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire.
C. 65:
Indicates the aspect ratio
which gives the tire's ratio of
height to width.
D. R:
Indicates a radial type tire.
E. 15:
Indicates the wheel or rim
diameter in inches. If you change
your wheel size, you will have to
purchase new tires to match the
new wheel diameter.
F. 95:
Indicates the tire's load
index. It is an index that relates to
how much weight a tire can carry.
Note: You may not find this
information on all tires because it
is not required by federal law.
G. H:
Indicates the tire's speed
rating. The speed rating denotes
the speed at which a tire is
designed to be driven for extended
periods of time under a standard
