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
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.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
5. Re-start the engine and take your vehicle to an authorized dealer.
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.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.

If an overfill occurs, excess fluid should be removed by an authorized
dealer.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
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.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft part numbersin this chapter.
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.
Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter element edges between the air filter
housing and cover. This could cause filter damage and allow unfiltered
air to enter the engine if not properly seated.
