USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels
to power the vehicle. This increases
traction, enabling you to drive over
terrain and road conditions that a
conventional two-wheel drive vehicle
cannot. The AWD system is active all
the time and requires no input from
the operator.
Note:
Your AWD vehicle is not
intended for off-road use. The AWD
feature gives your vehicle some limited
off-road capabilities in which driving
surfaces are relatively level,
obstruction-free and otherwise similar
to normal on-road driving conditions.
Operating your vehicle under other than
those conditions could subject the
vehicle to excessive stress which might
result in damage which is not covered
under your warranty.
Note: A warning message will be
displayed in the information display
when an AWD system fault is present
See Information Messages (page 105).
An AWD system fault will cause the
AWD system to default to front-wheel
drive only mode. When this warning
message is displayed, have your vehicle
serviced at an authorized dealer Note:
A warning message will be
displayed in the information display if
the AWD system has overheated See
Information Messages (page 105).
This condition may occur if the vehicle
was operated in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function
as soon as possible, stop the vehicle in
a safe location and stop the engine for
at least 10 minutes. After the engine
has been restarted and the AWD
system has adequately cooled, the
warning message will turn off and
normal AWD function will return.
Do not use a spare tire of a different
size other than the tire provided. If the
mini-spare tire is installed, the AWD
system may disable automatically
and enter front-wheel drive only mode
to protect driveline components. This
condition will be indicated by a
warning in the information display
See
Information Messages (page
105). If there is a warning message in
the information display from using the
spare tire, this indicator should turn
off after reinstalling the repaired or
replaced normal road tire and cycling
the ignition off and on. It is
recommended to reinstall the repaired
or replaced road tire as soon as
possible. Major dissimilar tire sizes
between the front and rear axles
could cause the AWD system to stop
functioning and default to front-wheel
drive or damage the AWD system.

All-Wheel Drive
(If Equipped)

Note:
For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your
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 or antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant WARNINGS
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. 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. 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. Do not add coolant further than
the MAX mark. Note:
Do not use stop leak pellets,
cooling system sealants, or additives
as they can cause damage to the
engine cooling or heating systems. This
damage would not be covered under
your vehicle ’s warranty.
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 the
engine coolant to be drained, the
system to be flushed, or the engine
coolant to be replaced.
• 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 Capacities and
Specifications (page 325).
• In case of emergency, a large
amount of water without engine
coolant may be added in order to
reach a vehicle service location. In
this instance, the cooling system
must be drained, chemically
cleaned with Motorcraft®
Premium Cooling System Flush,
and refilled with prediluted engine
coolant as soon as possible. Water
alone (without engine coolant)
can cause engine damage from
corrosion, overheating or freezing.

What you Should Know About
Fail-Safe Cooling
If the engine coolant supply is
depleted, this feature allows the
vehicle to be driven temporarily before
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 and: The coolant temperature
warning light will illuminate.
The service engine soon
indicator will illuminate.
If the engine reaches a preset
over-temperature condition, the
engine will automatically switch 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 completely shut down, causing
steering and braking effort to increase. Once the engine temperature cools,
the engine can be re-started. Take
your vehicle to an authorized dealer
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 the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to
rest in a safe location and seek
immediate repairs. When in fail-safe
mode, the 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 while the engine is
running or hot. You have limited engine power when
in the fail-safe mode, so drive the
vehicle with caution. The vehicle will
not be able to maintain high-speed
operation and the engine will run
rough. Remember that the engine is
capable of completely shutting down
automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken
to an authorized dealer.

Maintenance

3. If this is not possible, wait a short
period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without
repairing the engine problem increases
the chance of engine damage. Take
your vehicle to an authorized dealer as
soon as possible.
AUTOMATIC
TRANSMISSION FLUID
CHECK
Note: Transmission fluid should be
checked by an authorized dealer. If
required, fluid should be added by an
authorized dealer.
The automatic transmission does not
have a transmission fluid dipstick.
Have an authorized dealer check and
change the transmission fluid and
filter at the correct service interval.
See Scheduled Maintenance (page
440). Your transmission does not
consume fluid. However, the fluid level
should be checked if the transmission
is not working properly, or if you notice
some sign of fluid leakage.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials
may affect transmission operation
and result in damage to internal
transmission components. 6F35/HF35 transmission
