Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids
WARNING: Do not use starting
fluid, such as ether, in the air intake
system (see air filter decal). Such fluid
could cause immediate explosive
damage to the engine and possible
personal injury.
The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures. See Engine Block
Heater (page 103).Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
dash-mounted upfitter switches that
allows the operator to elevate the idle rpm
for extended idle periods, as well as
aftermarket equipment such as PTO
operation. You must configure this feature
even if ordered from the factory. See your
authorized dealer for required upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to 199 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note:Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15–30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.

CHANGING THE ENGINE AIR
FILTER - 6.7L DIESEL
Air Filter Restriction Gauge
WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: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 plug
or soak the air filter and cause the engine to
lose power or shut down.
E163372
The restriction gauge, on the upper housing
of the air filter assembly, measures the
vacuum inside the air filter. The more the
air filter is dirty or clogged, the higher the
vacuum reading.
Check the air filter restriction gauge
whenever you open the hood to perform
general engine maintenance or at least
every 7,500 mi (12,000 km). If you operate
your vehicle in extremely dusty conditions,
check and reset the gauge at least every
500 mi (800 km), or two weeks, whichevercomes first. Change the air filter when the
restriction gauge reads near the change
filter line and the gauge is yellow. If you
allow the restriction gauge to reach
maximum restriction, you can affect your
engine performance and fuel economy.
Note:Do not blow out the air filter element
with compressed air since the compressed
air could damage the filter paper.
Note:Do not rely on filter appearance
alone. A filter which appears to be dirty may
have several thousand miles (kilometers)
of life remaining.
E163373
After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.
We recommend the following actions after
operating the vehicle up to 200 mi
(320 km) in heavy snowfall or extreme
rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet. Do NOT
remove the foam filter and reset the
air filter restriction gauge.
• Extreme rain: The air filter dries after
about 15–30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.

Maintenance

change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
coolant temperature gauge moves toward
the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
switches to alternating cylinder operation.
Each disabled cylinder acts as an air pump
and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
shutting down to prevent engine damage.
In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside
assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short
period for the engine to cool.

Maintenance

5. Turn the air conditioning (if equipped)
on and allow the engine to idle for at
least one minute.
6. Release the parking brake. With your
foot on the brake pedal and with the
air conditioning on, put the vehicle in
drive (D) and allow the engine to idle
for at least one minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the
relearning process
• The vehicle may need to be driven
10 mi (16 km) or more to relearn the
idle and fuel trim strategy along
with the ethanol content for flexible
fuel vehicles.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
control fan, heated steering wheel, audio
and navigation system. A message may be
shown in the information displays to alertthe driver that battery protection actions
are active. These messages are only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
Electrical accessory installation
To ensure proper operation of the BMS,
any electrical devices that are added to
the vehicle should not have their ground
connection made directly at the negative
battery post. A connection at the negative
battery post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note:Electrical or electronic accessories
added to the vehicle by the dealer or the
owner may adversely affect battery
performance and durability, and may also
affect the performance of other electrical
systems in the vehicle.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
which matches the electrical requirements
of the vehicle. After battery replacement,
or in some cases after charging the battery
with the external charger, the BMS requires
eight hours of vehicle sleep time (key off
with doors closed) to relearn the new
battery state of charge. Prior to relearning
the state of charge, the BMS may disable
electrical features (to protect the battery)
earlier than normal.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, the
alignment of your headlamps should be
checked by your authorized dealer.
