BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the“MAX”line
that do not trigger the brake system
warning lamp 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 your brake system could be compromised, seek
service from your dealer immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the fluid level. Refer to the scheduled maintenance guide for the
service interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
Use only a DOT 3 brake fluid designed 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.

1Add the coolant type originally equipped in your vehicle.2Service refill capacity is determined by filling the transfer case to the
bottom of the filler hole with the vehicle on a level surface.
3Ensure 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.
4Approximate dry fill capacity including transmission fluid cooling
system, actual refill capacities will vary based on vehicle application and
transmission fluid cooling system (i.e. coolers size, cooling lines. auxiliary
cooler capacities). The amount of transmission fluid and fluid level
should be set by the indication on the dipstick’s normal operating range.
5Your 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.
6Service refill capacity is determined by filling the axle to 6-14 mm
(1/4-9/16 inch) below the bottom of the filler hole with the vehicle on a
level surface.
