Temperature control: Adjusts
the temperature of the air
circulated in your vehicle.

MAX Defrost:
Turn to the right
to switch on defrost. Air flows
through the windshield vents
and the fan adjusts to the
highest speed. You can also use
this setting to defog and clear
the windshield of a thin covering
of ice. The heated rear window
also turns on when you select
maximum defrost.
F
Note:
To prevent window
fogging, you cannot select
recirculated air when maximum
defrost is on.
MAX A/C:
Turn to the left for
maximum cooling. Recirculated
air flows through the instrument
panel vents, air conditioning
turns on and the fan adjusts to
the highest speed.
G A/C:
Press to switch the air
conditioning on or off. Use A/C
with recirculated air to improve
cooling performance and
efficiency.
H
Note:
In certain conditions (for
example, maximum defrost), the
air conditioning compressor may
continue to operate even though
you switch off the air
conditioning.
Heated seats:
Press to switch
the heated seats on and off. See

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Climate Control

AUTO: Press to switch on
automatic operation. Adjust to
select the desired temperature.
Fan speed, air distribution, air
conditioning operation, and
outside or recirculated air adjust
A
to heat or cool the vehicle to
maintain the desired
temperature. You can also
switch off dual zone mode by
pressing and holding for more
than two seconds.
MAX Defrost:
Press to switch
on defrost. The driver and
passenger settings set to HI, air
flows through the windshield
vents, and the fan adjusts to the
highest speed. You can also use
this setting to defog and clear
the windshield of a thin covering
of ice. The heated rear window
also turns on when you select
maximum defrost.
B Note:
To prevent window
fogging, you cannot select
recirculated air when maximum
defrost is on.
Power:
Press to switch the
system on and off. When the
system is off, it prevents outside
air from entering the vehicle.
C
Air distribution control: Press
to switch air flow from the
windshield, instrument panel or
footwell vents on or off. You can
distribute air through any
combination of these vents.
D
Recirculated air:
Press to
switch between outside air and
recirculated air. The air currently
in the passenger compartment
recirculates. This may reduce the
time needed to cool the interior
(when used with A/C) and
reduce unwanted odors from
entering your vehicle.

Note: Recirculated air may turn
off (or prevent you from
switching on) in all air flow
modes except MAX A/C to
reduce the risk of fogging.
Recirculation may also turn on
and off in Panel or Panel/Floor
air flow modes during hot
weather in order to improve
cooling efficiency.
MAX A/C:

HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.
Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.

Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.
If you drive in extremely hot climates:
• It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40%
provides improved overheat
protection. Coolant concentrations
below 40% decrease the freeze and
corrosion protection characteristics of
the coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
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
automatically 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 WARNINGS
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. Never remove the coolant reservoir
cap when the engine is running or
hot.
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.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Maintenance

Remember that the engine is capable of
automatically 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.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management (If Equipped) WARNING
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not
be able to accelerate with full power until
the coolant temperature reduces. If you tow a trailer with your vehicle, the
engine may temporarily reach higher a
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display. You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no
need to pull off the road. You can continue
to drive your vehicle.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park
(P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
