EST-M2C118–A for complete refill of limited slip Ford axles. Ford design rear axles contain a
synthetic lubricant that does not require changing unless the axle has been submerged in water.2Add the coolant type originally equipped in your vehicle.3Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick blade or the dipstick handle. Check the container to verify the fluid being
added is of the correct type. Refer to yourscheduled maintenance informationto determine the
correct service interval.
Automatic transmissions that require MERCON
SP should only use MERCON
SP fluid.
Use of a dual usage fluid in an automatic transmission requiring MERCON
SP may cause
transmission damage. Use of any fluid other than the recommended fluid may cause
transmission damage.4Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface. The 6–speed manual transmission is equipped with an in-tank cooler.
Verify the fluid level after operating vehicle to ensure correct fluid level.5Indicates 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.6Use 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.

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 your authorized dealer.
•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.
