CHANGING THE 12V BATTERY
WARNING: This vehicle may be
equipped with more than one battery,
removal of cable from only one battery
does not disconnect the vehicle
electrical system. Be sure to disconnect
cables from all batteries when
disconnecting power. Failure to do so
may cause serious personal injury or
property damage. WARNING:
Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide proper ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately.
Note: If your battery has a cover/shield,
make sure it is reinstalled after the battery
has been cleaned or replaced. Note:
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after handling.
Note: Electrical or electronic accessories
or components added to the vehicle by the
dealer or the owner may adversely affect
battery performance and durability.
Your vehicle is equipped with a Motorcraft
maintenance-free battery which normally
does not require additional water during
its life of service.
For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
Because your vehicle ’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. To begin this
process
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in park (P) or neutral (N) and turn off all accessories.
3. Start the engine. Run the engine until it reaches normal operating
temperature.
4. Allow the engine to idle for at least one
minute.

CHANGING A BULB WARNING: Bulbs can become hot.
Let the bulb cool down before removing
it. Failure to do so could result in
personal injury. Headlamp bulbs must be marked with an
authorized D.O.T. marking for North
America to make sure they have the proper
lamp performance, light brightness, light
pattern and safe visibility.
Install in the reverse order unless otherwise
stated.

system.
ELECTRICAL SYSTEM
INSPECTION
Periodically inspect electrical connectors
on the outside of the cab and on the engine
and frame for corrosion and tightness.
Exposed terminals, such as the fuel sender,
cranking motor, alternator and
feed-through studs, should be cleaned and
re-coated with a lubricant sealing grease
such as Motorcraft Silicone Brake Caliper
Grease and Dielectric Compound XG-3, or
equivalent. This should include the ground
cable connector for batteries, engine and
cab as well as the jump-starting stud.
Accessory Feed Connections
Vehicle electrical systems are complex and
often include powertrain components,
such as engine and transmission controls,
instrument panels and ABS. While most
systems operate on battery voltage (12
volts), some systems can be as high as 90
volts or as low as five volts. See the
Electrical Circuit Diagram Manuals,
available from your vehicle ’s manufacturer,
to make sure that any extra body lights and
accessory connections to circuits are both
appropriate and not overloaded. Do not
make modifications to any vehicle control
system without first contacting an
authorized dealer. AIR INDUCTION SYSTEM
INSPECTION WARNING: When performing
maintenance to any turbocharged engine
with engine air inlet piping disconnected,
keep loose clothing, jewelry and long hair
away from the engine air inlet piping. A
turbocharger compressor air inlet
protective shield should be installed over
the turbocharger air inlet to reduce the
risk of personal injury or death.
Perform a complete inspection of the air
induction system annually.
In areas where road salt is used,
disassemble the joints of each aluminum
component and inspect for salt build-up
and presence of chlorine that can cause
aluminum particles to flake off and enter
the engine combustion chambers. If
evidence of corrosion is found (usually at
the pipe connections), use a wire brush to
clean the inside of the pipes and inside the
rubber hoses.
If pitting is evident at the joint ends of the
intake pipes, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the
joints. Make sure no excess material, which
can pull into the engine, is on the inside of
the pipes. If the service condition of the
pipes, hoses or clamps is questionable,
replace the defective part(s).
Make sure to clean all dust and debris out
of the pipes and couplings with a clean,
damp rag before reassembly.
Chassis-mounted Charge Air
Cooler
Visually inspect the core assembly for
debris and clogging of external fins with
the engine off.

To clean the windshield and wiper blades:
•
Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.
• For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
Note: Do not use razor blades or other
sharp objects to clean or remove decals
from the inside of the heated rear window.
The vehicle warranty does not cover
damage caused to the heated rear window
grid lines.
CLEANING THE INTERIOR WARNING: Do not use cleaning
solvents, bleach or dye on the vehicle's
seatbelts, as these actions may weaken
the belt webbing. WARNING:
On vehicles equipped
with seat-mounted airbags, do not use
chemical solvents or strong detergents.
Such products could contaminate the
side airbag system and affect
performance of the side airbag in a crash.
For fabric, carpets, cloth seats and seats
equipped with side airbags:
• Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner. •
If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.
Mirrors
Do not clean the housing or glass of any
mirror with harsh abrasives, fuel or other
petroleum or ammonia-based cleaning
products.
CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS WARNING:
Do not use chemical
solvents or strong detergents when
cleaning the steering wheel or
instrument panel to avoid contamination
of the airbag system.
Note: Follow the same procedure as
cleaning leather seats for cleaning leather
instrument panels and leather interior trim
surfaces.

*Traction: The traction grades,
from highest to lowest are AA, A,
B, and C. The grades represent the
tire's ability to stop on wet
pavement as measured under
controlled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
*
Temperature: The temperature
grades are A (the highest), B and
C, representing the tire's
resistance to the generation of
heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
M. Maximum Inflation
Pressure:
Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label. The cold
inflation pressure should never be
set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have
additional markings, notes or
warnings such as standard load
or radial tubeless. Additional Information
Contained on the Tire Sidewall

Note:
Some spare tires operate at
a higher inflation pressure than the
other tires. For T type mini-spare
tires, see the Dissimilar spare wheel
and tire assembly information for
a description. Store and maintain
at 60 psi (412 kPa). For full-size
and dissimilar spare tires, see the
Dissimilar spare wheel and tire
assembly information for a
description. Store and maintain at
the higher of the front and rear
inflation pressure as shown on the
Safety Compliance Certification
Label or Tire Label.
6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.
7. Check the sidewalls to make sure there are no gouges, cuts
or bulges.
Tire Inflation Information WARNING: An inflated tire
and rim can be very dangerous
if improperly used, serviced or
maintained. To reduce the risk
of serious injury, never attempt
to re-inflate a tire which has been run flat or seriously
under-inflated without first
removing the tire from the wheel
assembly for inspection. Do not
attempt to add air to tires or
replace tires or wheels without
first taking precautions to
protect persons and property.
All tires with Steel Carcass Plies
(if equipped):
This type of tire utilizes steel cords
in the sidewalls. As such, they
cannot be treated like normal light
truck tires. Tire service, including
adjusting tire pressure, must be
performed by personnel trained,
supervised and equipped
according to Federal Occupational
Safety and Health Administration
regulations. For example, during
any procedure involving tire
inflation, the technician or
individual must utilize a remote
inflation device, and ensure that
all persons are clear of the
trajectory area.

There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle
’s
time out of service.
Air Brake Adjustment WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check Every Month
Air filter restriction gauge. 1
Engine oil level.
Fuel and water separator. Drain if necessary, or if indicated by the information display. 1
Function of all interior and exterior lights.
