•DEF freezes below 12°F (-11°C). Your vehicle is equipped with an
automatic pre-heating system which allows the DEF system to
operate below 12°F (-11°C).
•Do not store the DEF bottle in your vehicle. If it leaks, it could cause
damage to interior components or release an ammonia odor inside
your vehicle.
•Store DEF out of direct sunlight and in temperatures between
23°F–68°F (-5°C–20°C).
NOISE EMISSIONS
In order to keep to the federal exterior noise regulations, your vehicle
may be equipped with noise emission items. Depending on your vehicle
configuration, it may have all or some of the following items:
Air Intake System:Inspect the air cleaner. Do not alter its location. Do
not alter inlet and outlet piping.
Body:Inspect wheel well splash shields, cab shields and under hood
insulation for deterioration, dislocation and orientation.
Cooling System:
•Inspect the fan for blade damage. If you find any damage, replace
with the recommended parts. Inspect for fan-to-shroud interference
and any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers damp-out engine mechanical
noise. If they need replacing, make sure to replace them with the
recommended parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•
Perform a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended replacement parts.
•Do not change the tail pipe elbow or offset tail pipe orientation from the

GENERAL INFORMATION
All standard equipment brakes self-adjusting. Automatic adjustment,
when required, occurs whenever you apply and release the brakes during
forward or reverse operation.
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, this may indicate worn
brake linings. Have them inspected by an authorized dealer. If your
vehicle has continuous vibration or shudder in the steering wheel while
braking, an authorized dealer should inspect the vehicle.
Know the required stopping distances for all driving conditions you may
encounter. For longer brake lining life, take full advantage of engine
braking power when coming to a stop.
WARNING:Do not drive with your foot resting on the brake
pedal. This results in abnormally high brake temperatures,
excessive lining wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you use to ascend the hill.
WARNING:Continuous application of the brakes causes the
brakes to overheat, resulting in a temporary loss of braking.
See theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
If Brakes Do Not Grip Well
•If you have been driving through deep water, gently apply the brakes
several times while your vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure on vehicles equipped with air brakes.

WARNING:Do not drive or continue to drive if the low air
pressure buzzer is sounding or the brake warning light is lit.
These warnings indicate that air pressure is not to normal operating
level. Continued use of the vehicle could result in loss of braking ability.
WARNING:Avoid repeated light application of the brake pedal.
This depletes air pressure faster and could result in loss of
braking capability.
Periodically check the air pressure
gauge while driving. Pressure should
range between approximately
100–125 psi (690–862 kPa). The air
compressor governor cut-in and
cutout pressure settings are set at
the factory and are not adjustable.
When air pressure is insufficient (below 60 psi [414 kPa]), a
warning light illuminates and a buzzer sounds when the ignition
is in the on position.
This may happen because excessive brake applications are depleting the
system air pressure. If this condition occurs, stop driving your vehicle
until the compressor has fully recharged the air system.
WARNING:Do not move the vehicle when the air pressure is
insufficient because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplementing with brakes, as required, help to safely slow the vehicle
and avoids overspeeding the engine.
Air Chamber Stroke Indication
Air chamber push rods have orange stroke indicator markers that warn
when the braking system requires adjustment or repair. The painted
orange indicator is on the air chamber push rod at the slack adjuster
stroke dimension that requires service when visible during brake
application.

Quality service parts are available through an authorized dealer. If dealer
parts are not used, make sure the replacement parts are of equivalent
quality.
WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
To avoid damage to your vehicle’s electrical components before electric
welding:
•Disconnect both battery cables.
•Attach the welder ground cable as close as possible to the part being
welded.
•We recommend temporarily removing the component if welding close
to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have an authorized dealer or service center inspect your vehicle at least
once a year. Remember that regular maintenance and inspections usually
prevent serious problems from developing later.
If the owner or operator of the vehicle is a skilled technician and intends
on performing the vehicle maintenance and service, he is strongly urged
to purchase a service manual.
Electrical System
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.

Gasoline Engine
Checking the Engine Coolant
When the engine is cold, check the concentration and level of engine
coolant at the intervals listed in theScheduled Maintenancechapter.
Note:Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:If the level is at the MIN mark, below the MIN mark, or empty,
add coolant immediately. SeeAdding engine coolantin this section.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240 available from an
authorized dealer. Ford does not recommend the use of hydrometers or
coolant test strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.

Note:Do not use stop leak pellets or cooling system sealants or
additives as they can cause damage to the engine cooling and heating
systems. Your vehicle’s warranty does not cover this damage.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require draining the engine coolant,
flushing the system, or replacing the engine coolant.
•DO NOT MIX different colors or types of coolant in your vehicle.
Make sure the correct coolant is used. Mixing of engine coolants may
harm your engine’s cooling system. The use of an improper coolant
may harm engine and cooling system components and may void the
warranty. Use prediluted engine coolant meeting the Ford
specification. See theCapacities and Specificationschapter for
more information.
•In case of emergency, you may add a large amount of water without
engine coolant in order to reach a vehicle service location. In this
instance, drain the cooling system, chemically clean it with Motorcraft
Premium Cooling System Flush, and refill it with engine coolant as
soon as possible. Water alone (without engine coolant) can cause
engine damage from corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants mixed
with alcohol or methanol antifreeze (coolant). Alcohol and other
liquids can cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specificationsfor more information.
Whenever you add coolant, check the coolant level in the coolant
reservoir the next few times you drive your vehicle. If necessary, add
enough prediluted engine coolant to bring the coolant level to the proper
level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Dispose of used engine coolant in an appropriate manner. Follow your
community’s regulations and standards for recycling and disposing of
automotive fluids.
