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.
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.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
For information on transmission operation after the battery has been
disconnected see“Shift strategy”in the driving section.
To account for customer driving habits and conditions, your automatic
transmission (4R70W) electronically controls the shift quality by using an
adaptive learning strategy. The adaptive learning strategy is maintained
by power from the battery. When the battery is disconnected or a new
battery is installed, the transmission must relearn its adaptive strategy.
Optimal shifting will resume within a few hundred kilometers (miles) of
operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally or after a long
deceleration period, see your dealer or a qualified service
technician as soon as possible.
Because your vehicle’s engine is also 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.

2. Visually inspect the fluid level.
3. If necessary, add brake fluid from
a clean un-opened container until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specification ESA-M6C25–A. Refer toLubricant
specificationsin this chapter.
Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical attention if
irritation persists. If taken internally, drink water and induce vomiting.
Seek medical attention immediately.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the fluid level in the reservoir for the master cylinder
fall below the MIN mark. If master cylinder runs dry, this may
cause the brakes to fail.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your scheduled maintenance guide for 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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.

High fluid level
Fluid levels above the safe range
may result in transmission failure.
An overfill condition of transmission
fluid may cause shift and/or
engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Lubricant specificationssection in this chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 250 mL (1/2 pint) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by a qualified
technician.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
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.
DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to the scheduled maintenance guide for maintenance
intervals. If the original universal joints are replaced with universal joints
equipped with grease fittings, lubrication will also be necessary.
AIR FILTER MAINTENANCE
Refer to the scheduled maintenance guide for the appropriate intervals
for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft Part Numbers.
Note:Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.

1Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. Check the container to verify the fluid being added is of the
correct type. Refer to your scheduled maintenance guide to determine
the correct service interval.

Some transmission fluids may be labeled as dual usage, such as
MERCONand MERCONV. These dual usage fluids are not to be used
in an automatic transmission that requires use of the MERCONtype
fluid. However, these dual usage fluids may be used in transmissions that
require the MERCONV type fluid.
MERCONand MERCONV type fluids are not interchangeable.
DO NOT mix MERCONand MERCONV. Use of a transmission
fluid that indicates dual usage (MERCONand MERCONV) in
an automatic transmission application requiring MERCONmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
2Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
3Add the coolant type originally equipped in your vehicle.
4Your 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.
Service refill capacities are determined by filling the rear axle 9mm to
12mm (3/8 inch to 1/2 inch) below the bottom of the filler hole.
5Add 118 ml (4 oz.) of Additive Friction Modifier XL-3 (or equivalent)
meeting Ford specification EST-M2C118–A for complete refill of Limited
Slip axles.
