5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer toMaintenance
product specifications and capacitiesin this chapter for the proper
fluid type.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
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.
TRANSMISSION FLUID
Checking automatic transmission fluid
The automatic transmission does not have a transmission fluid dipstick.
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.
Transmission fluid should be checked by an authorized dealer. If
required, fluid should be added by an authorized dealer.
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.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the air filter element
listed. Refer toMotorcraft part numbersin this chapter.

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.
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.

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.

1Add the coolant type originally equipped in your vehicle.2Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.3Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler.4Automatic transmissions that require MERCONLV should only use MERCONLV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.5Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated
for life. These lubricants are not to be checked or changed unless a leak is suspected, service is
required or the axle has been submerged in water. The axle lubricant should be changed any time
the axle has been submerged in water.
