Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine 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 the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets, cooling system sealants or additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
•
DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of engine coolants may harm
your engine’s cooling system. The use of an improper coolant may harm
engine and cooling system components and may void the warranty.

If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and:
The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
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 restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.

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.
CHANGING THE VEHICLE 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
proper 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/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds.Note:Wash hands after
handling.
Note:If your battery has a cover/shield, make sure it is reinstalled after
the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.

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.
