Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability.
Your vehicle is equipped with a Motorcraft® maintenance-free battery
which normally does not require additional water during its life of
service.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•Note:If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is reconnected.

CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
CHANGING THE WIPER BLADES
Replace wiper blades at least once per year for optimum performance.
To replace the wiper blades:
1. Fold back the wiper arm and
position the wiper blade at a right
angle to the wiper arm.
2. To remove the wiper blade, press
the retaining clip (A) to disengage
the wiper blade, then pull the blade
down toward the windshield to
remove it from the arm.
3. Install the new wiper blade on the arm and press it into place until a
click is heard.
Poor wiper quality can be improved by cleaning the wiper blades and
windshield. Refer toWindows and wiper bladesin theCleaning
chapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers.
The layer of ice has many sharp edges and can damage the micro edge
of the wiper rubber element.

Changing the Rear Window Wiper Blade
To replace the rear wiper blade:
1. Pull the wiper arm as far away from the glass as possible. Do not use
excessive force because it can break the wiper arm. Hold it there until
the next step.
2. Grasp the wiper blade and rotate
it away from the wiper arm using
moderate force until it disengages
from the wiper arm.
3. Once the wiper blade is loose,
slide it away from the wiper arm.
4. To attach the new wiper to the
wiper arm, align the cross pin and
keyway (denoted with the arrows)
and firmly press the wiper blade
into the wiper arm until an audible
snap is heard.
If you find this procedure too difficult, please see your dealer.
AIR FILTER CHECK
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.
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. SeeMotorcraft® Part Numbersin theCapacities and
Specificationschapter.

SeeScheduled Maintenance Informationfor 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 Element
1. 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.

5. Release the three clamps that secure
the cover to the air filter housing. Push
the air filter cover toward the center of
the vehicle and up slightly to release it.
6. Remove the air filter element
from the air filter housing.
7. Install a new air filter element.
8. Replace the air filter housing
cover and secure the clamps.
Be careful not to crimp the filter
element edges between the air filter
housing and cover and ensure that
the tabs on the edge are properly
aligned into the slots.
9. Slip the air tube onto the air
filter housing and tighten the
air-tube clamp bolt snugly, but do
not overtighten it.
10. Reconnect the mass air flow
sensor electrical connector to the
outlet tube. Make sure the locking
tab on the connector is in the
“locked” position (connector shown
from below for clarity).

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
Vertical Aim Adjustment
Before aim adjustment, disable the air suspension system. Refer to
Message centerin theDriver Controlschapter.
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
•(A) 8 feet (2.4 meters)
•(B) Center height of lamp to
ground
•(C) 25 feet (7.6 meters)
•(D) Horizontal reference line
2. Measure the height from the center of your headlamp (indicated by
a 3.0 millimeter circle on the lens) to the ground and mark an 8 foot
(2.4 meter) horizontal reference line on the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light from that lamp
hits the wall.
4.
On the wall or screen you will
observe a light pattern with a distinct
horizontal edge towards the right.
If this edge is not at the horizontal
reference line, the beam will need to
be adjusted so the edge is at the
same height as the horizontal
reference line.

5. Locate the vertical adjuster on
each headlamp, then use a Phillips
#2 screwdriver to turn the adjuster
either counterclockwise or
clockwise in order to adjust the
vertical aim of the headlamp. The
upper edge of the light pattern
should touch the horizontal
reference line.
6. HORIZONTAL AIM IS NOT REQUIRED FOR THIS VEHICLE AND IS
NOT ADJUSTABLE.
7. Repeat Steps 3–5 for the other headlamp.
8. Close the hood and turn off the lamps.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
These are examples of acceptable condensation:
•Presence of thin mist (no streaks, drip marks or droplets).
•Fine mist covers less than 50% of the lens.
These are examples of unacceptable moisture (usually caused by a lamp
water leak):
•Water puddle inside the lamp.
•Large water droplets, drip marks or streaks present on the interior of
the lens.
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
