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.
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.
Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, 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.
AUTOMATIC TRANSMISSION
FLUID CHECK
The automatic transmission does not have
a transmission fluid dipstick.
Have an authorized dealer check and change
the transmission fluid at the correct service
interval. See Scheduled Maintenance (page
495
). Your transmission does not consume
fluid. However, if the transmission slips, shifts
slowly or if you notice a sign of leaking fluid,
contact an authorized dealer.

Note:
If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See
Capacities and Specifications (page
385).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide. WASHER FLUID CHECK WARNING:
If you operate your
vehicle in temperatures below 41.0°F (5°C),
use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase
the risk of injury or accident.
Note: The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets our
specifications.
See Capacities and
Specifications (page 385).
State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle ’s
paint finish, wiper blades or washer system. 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.
CHANGING THE 12V BATTERY
WARNING:
Batteries normally
produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you have
your vehicle serviced at the proper times.
These intervals serve two purposes; one is
to maintain the reliability of your vehicle and
the second is to keep your cost of owning
your vehicle down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 385).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the operation
of your vehicle. Ask your dealership about
the training and certification their technicians
have received.
Genuine Ford and Motorcraft® Replacement
Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use our authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one stop
shopping. They can perform any services
that are required on your vehicle, from
general maintenance to collision repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
emission control systems, make sure you
have scheduled maintenance performed at
the designated intervals.

Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle
sub-systems during scheduled maintenance. It is critical that systems are flushed only with
new fluid that is the same as that required
to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check Every Month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level.

Axle and PTU maintenance: The Power
Transfer Unit (PTU) and rear axle (AWD only)
in your vehicle does not require any normal
scheduled maintenance. The PTU lubricant
may be more likely to require a fluid change
if the vehicle has extended periods of
extreme or severe duty cycle driving.
Changing or checking the PTU lubricant is
not necessary unless the unit has been
submerged in water, shows sign of leakage.
Contact your authorized dealer for service. California fuel filter replacement: If you
register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. We however, urge you to have all
recommended maintenance services
performed at the specified intervals and to
record all vehicle service. Engine air filter and cabin air filter
replacement: The life of the engine air filter
and cabin air filter is dependent on exposure
to dusty and dirty conditions. Vehicles
operated in these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.
