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
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 for a short period of time 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 a higher
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 stop your vehicle. You can
continue to drive.

4. Make sure that the fluid level is
between the MIN and the MAX marks.
If the fluid level is at the MIN mark, add
fluid immediately. See Adding
Transmission Fluid.
5. Replace the automatic transmission fluid cap and dipstick. Turn it clockwise
until you feel a strong resistance.
Low Fluid Level
If the fluid level is within the minimum
range (below point A) add the correct
specification fluid to be within the hash
mark area. See
Capacities and
Specifications (page 305).
Note: If the fluid level is below the
minimum range do not drive your vehicle. A
low fluid level can damage the transmission.
Correct Fluid Level
If the fluid level is within the hash mark
area (between points A and B) do not add
any fluid.
High Fluid Level
If the fluid level is above the maximum
range (above point B) fluid may need to
be removed. High fluid levels may be
caused by a overheating condition. If you
have operated your vehicle at high speeds,
towing a trailer or in city traffic during hot
weather, allow your vehicle to cool for a
minimum of 30 minutes before rechecking
the level.
Note: An overfill condition can damage the
transmission.
Adding Transmission Fluid *
1. Rotate the automatic transmission fluid cap in a counterclockwise
direction.
2. Remove the cap and dipstick and wipe
it with a clean, lint-free cloth. 3. Add fluid that meets the Ford
specifications. See
Capacities and
Specifications (page 305). Pour the
fluid directly into the automatic
transmission fluid cap and dipstick
hole.
4. Replace the cap and dipstick and remove it again to check the fluid level.
5. Make sure that the fluid level is between the MIN and the MAX marks.
6. Replace the automatic transmission fluid cap and dipstick. Turn it clockwise
until you feel a strong resistance.
* Vehicles With Turbocharged Engines WARNING:
Do not start the engine
with the air filter removed. This can cause
damage not covered by the vehicle
Warranty and can result in serious injury.
1. Loosen the clamp holding the air filter assembly to the rubber hose.
2. Remove the air filter assembly securing
bolts.
3. Lift the air filter assembly to disengage
the locating pins.
4. Rotate the air filter assembly slightly in a counterclockwise direction.
5. Check the transmission fluid level.
6. Install the air filter assembly in reverse
order. Tighten the air filter assembly
securing bolts until you feel a strong
resistance.
