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.Wash hands after handling.
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. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.
7. 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.
•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.

Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the “COLD FILL RANGE” or the “FULL COLD” level on the
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant in vehicles originally equipped with Motorcraft Premium Gold
Engine Coolant since a Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.

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).

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your authorized dealer for
specific weight information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems — such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
•To avoid interference with other vehicle functions, such as anti-lock
braking systems, amateur radio users who install radios and antennas
onto their vehicle should not locate the Amateur Radio Antennas in
the area of the driver’s side hood.
•Electrical or electronic accessories or components that are added to
the vehicle by the authorized dealer or the owner may adversely affect
battery performance and durability.
