WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING: 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 you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 475).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal 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.
It is very important to use prediluted coolant
meeting the correct specification in order to
avoid plugging the small passageways in the
engine cooling system. See Capacities and
Specifications
(page 372). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 365).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

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 365). 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
2.0L Engines and 3.0L Engines with
FWD
Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
3.0L Engines with AWD
The fuel filter on your vehicle must be
replaced at the specified service interval.
See
Scheduled Maintenance (page 475). 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.

4.
On the wall or screen you will observe a
flat zone of high intensity light located at
the top of the right hand portion of the
beam pattern. If the top edge of the high
intensity light zone is not at the horizontal
reference line, the headlamp will need
to be adjusted. 5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the horizontal
reference line. 6. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
The horizontal aim does not require any
adjustment for this vehicle. If a fault occurs,
have the system checked by an authorized
dealer.
CHANGING A BULB
Replacing Bulbs
For replacing bulbs, see your authorized
dealer.
CHANGING THE ENGINE AIR
FILTER
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. Only use the specified replacement air filter.
See
Capacities and Specifications (page
365).
Change the air filter element at the correct
interval. See Scheduled Maintenance (page
475
).
When changing the engine air filter, do not
allow debris or foreign material to enter the
air induction system. The engine and
turbocharger are susceptible to damage from
even small particles.

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.
Fuel and water separator. Drain if necessary (or if indicated by the information display). Holes and slots in the tail pipe to make sure they are functional and clear of debris. Check Every Six Months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
