Cooled Seats
The cooled seats will only function when the engine is running.
To operate the cooled seats:Press the cooled seat symbol to cycle through the various
cooling settings and off. Cooler settings are indicated by
more indicator lights.
If the engine falls below 350 RPM while the cooled seats are on, the
feature will turn itself off. You will need to reactivate it.
Climate Controlled Seats Air Filter Replacement (If Equipped)
The climate controlled seat system includes air filters. You must replace
them periodically. See scheduled maintenance information for more
information.
There is a filter located under each front seat. You can access the filter
from the second row seat. Move the front seats all the way forward and
up to ease access.
To remove a filter:
1. Remove the key from the
ignition.
2. Press up on the outside rigid
edge of the filter and rotate
counterclockwise once the tabs are
released.

•Add particular accessories to your vehicle (e.g.; bug deflectors,
rollbars or light bars, running boards, ski racks).
• Drive with the wheels out of alignment.
DRIVING THROUGH WATER
WARNING: Do not drive through flowing or deep water as you
may lose control of your vehicle.
Note: Driving through standing water can cause vehicle damage.
Note: Engine damage can occur if water enters the air filter.
Before driving through standing water, check the depth. Never drive through water that is higher than the bottom
of the wheel hubs.
When driving through standing water, drive
very slowly and do not stop your vehicle. Your
brake performance and traction may be
limited. After driving through water and as
soon as it is safe to do so:
•Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the steering power assist works.
FLOOR MATS
WARNING: Always use floor mats that are designed to fit the
foot well of your vehicle. Only use floor mats that leave the pedal
area unobstructed. Only use floor mats that are firmly secured to
retention posts so that they cannot slip out of position and interfere
with the pedals or impair safe operation of your vehicle in other ways.
WARNING: Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious personal injury.

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.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines are within the normal
operating range; there is no need to add fluid. If the fluid levels are
outside of the normal operating range, the performance of the system
could be compromised; seek service from your authorized dealer
immediately.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill. For additional information on
the electric power steering (EPS) system, Refer toDriving Aids.
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.
WASHER FLUID CHECK
WARNING: If you operate your vehicle in temperatures below
40°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.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
the Capacities and Specifications chapter.
Note: The front and rear washer systems are supplied from the same
reservoir.
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.

personal burn injuries, do not start your engine with the air
cleaner removed and do not remove it while the engine is running.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
When changing the air filter element, use only the air filter element
listed. See Motorcraft® Part Numbers in theCapacities and
Specifications chapter.
See Scheduled Maintenance Information for the appropriate intervals
for changing the air filter element.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.

Changing the Air Filter Element1. Locate the mass air flow sensor
electrical connector on the air
outlet tube. This connector will
need to be unplugged.
2. Unlock the locking clip on the
connector (connector shown from
below for clarity), then squeeze and
pull the connector off of the air
outlet tube.
3. Clean the area around the air
tube to air cover connection to
prevent debris from entering the
system and then loosen the bolt on
the air tube clamp so the clamp is
no longer snug to the air tube. It is
not necessary to completely remove
the clamp.
4. Pull the air tube off from the air
cleaner housing.

•Spray Motorcraft Engine Shampoo and Degreaser on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
• Never wash or rinse the engine while it is hot or running; water in the
running engine may cause internal damage.
• Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
• Cover the battery, power distribution box, and air filter assembly to
prevent water damage when cleaning the engine.
CLEANING THE WINDOWS AND WIPER BLADES
The windows and wiper blades should be cleaned regularly. If the wipers
do not wipe properly, substances on the vehicle’s glass or the wiper
blades may cause squeaking or chatter noise from the blades, and
streaking and smearing of the windshield. To clean these items, follow
these tips:
• The windows may be cleaned with a non-abrasive cleaner such as
Motorcraft® Ultra-Clear Spray Glass Cleaner (U.S.) or Motorcraft
Premium Glass Cleaner (Canada).
• The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrates in the U.S., or
Motorcraft Premium Quality Windshield Washer Fluid in Canada.
Replace your wiper blades when they appear worn or do not function
properly.
• Do not use abrasive materials, as they may cause scratches.
• Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Note: Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause damage
to the rear window defroster’s heated grid lines.
