2003 FORD SUPER DUTY air condition

•the child has a medical condition which, according to the child’s
physician, makes it necessary for the child to ride in the front seat so
that the driver can constantlymonitor the child’s condition.
3.Medical condition.A passenger has a medical condition which,
according to his or her physician:
•causes the passenger air bag to pose a special risk for the passenger;
and
•makes the potential harm from the passenger air bag in a crash
greater than the potential harm from turning OFF the air bag and
allowing the passenger, even if belted, to hit the dashboard or
windshield in a crash.
This vehicle has special energymanagement safetybelts for the
driver and right front passenger. These particular belts are
specificallydesigned to work with air bags to help reduce the risk of
injuryin a collision. The energymanagement safetybelt is designed to
give or release additional belt webbing in some accidents to reduce
concentration of force on an occupant’s chest and reduce the risk of
certain bone fractures and injuries to underlying organs. In a crash, if
the air bag is turned OFF, this energymanagement safetybelt might
permit the person wearing the belt to move forward enough to incur a
serious or fatal injury. The more severe the crash, and the heavier the
occupant, the greater the risk is. Be sure the air bag is turned ON for
anyperson who does not qualifyunder the NHTSA deactivation
criteria.

SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properlyuse safety
restraints for children. Also seeAir bag supplemental restraint system
(SRS)in this chapter for special instructions about using air bags.
Important child restraint precautions
You are required bylaw to use safetyrestraints for children in the U.S.
and Canada. If small children (generallychildren who are four years old
or younger and who weigh 18 kg [40 lbs] or less) ride in your vehicle,
you must put them in safetyseats made especiallyfor children. Check
your local and state or provincial laws for specific requirements
regarding the safety of children in your vehicle. When possible, always
place children under age 12 in the rear seat of your vehicle. Accident
statistics suggest that children are safer when properlyrestrained in the
rear seating positions than in the front seating position.

Using the engine block heater (if equipped)
Use of an engine block heater is
stronglyrecommended if you live in
a region where temperatures reach
-23° C (-10° F) or below. For best
results, plug the heater in at least
three hours before starting the
vehicle. The heater can be plugged
in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings maybe worn-out
and should be inspected bya qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected bya qualified service technician.
Rear Anti-lock Brake System (RABS) (if equipped)
Your vehicle maybe equipped with a Rear Anti-lock Braking System
(RABS). This system helps you maintain steering control during

REPORTING SAFETY DEFECTS (U.S. ONLY)
If you believe that your vehicle has
a defect which could cause a crash
or could cause injuryor death, you
should immediatelyinform the National HighwayTraffic Safety
Administration (NHTSA) in addition to notifying Ford Motor Company.
If NHTSA receives similar complaints, it mayopen an investigation, and
if it finds that a safetydefect exists in a group of vehicles, it mayorder a
recall and remedycampaign. However, NHTSA cannot become involved
in individual problems between you, your dealer, or Ford Motor
Company.

•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling (if equipped)
If the engine coolant supplyis depleted, this feature allows the vehicle to
be driven temporarilybefore incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
andsymbol will
illuminate.
•TheService Engine Soon
indicator light will illuminate.
If the engine reaches a preset
over-temperature condition, the engine will automaticallyswitch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completelyshut down, causing steering and braking effort to
increase.

correct genuine Ford or Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completelyremoving the fuel filler cap. Otherwise, fuel may
sprayout and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank maydamage the fuel system or cause
the fuel cap to disengage in a collision, which mayresult in possible
personal injury.
