Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is
considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
1Add the coolant type originally equipped in your vehicle.
2Fill 6 mm to 14 mm (1/4 inch to 9/16 inch) below bottom of fill hole.
3Fill Dana rear axles to 6 mm to 14 mm (1/4 inch to 9/16 inch) below
bottom of fill hole.
4Ensure 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.
5Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with in-tank cooler. The amount of
transmission fluid and fluid level should be set by the indication on the
dipstick’s normal operating range.

the completed vehicle. In these cases the completed vehicle is
manufactured in two or more stages by two or more separate
manufacturers.

REPORTING SAFETY DEFECTS (U.S. ONLY)
If you believe that your vehicle has
a defect which could cause a crash
or could cause injury or death, you
should immediately inform the National Highway Traffic Safety
Administration (NHTSA) in addition to notifying Ford Motor Company.
If NHTSA receives similar complaints, it may open an investigation, and
if it finds that a safety defect exists in a group of vehicles, it may order a
recall and remedy campaign. However, NHTSA cannot become involved
in individual problems between you, your dealer, or Ford Motor
Company.
To contact NHTSA, you may either call the Auto Safety Hotline toll-free
at 1–800–424–9393 (or 366–0123 in the Washington D.C. area) or write
to:
NHTSA
U.S. Department of Transportation
Washington, D.C. 20590
You can also obtain other information about motor vehicle safety from
the Hotline.
