WINDSHIELD WASHER FLUID
Check the washer fluid
whenever you stop for
fuel. The reservoir is
highlighted with a
symbol.
Add fluid to fill the
reservoir if the level is
low. In very cold
weather, do not fill the
reservoir completely.
Only use a washer fluid that meets Ford
specification ESR-M17P5–A . Refer toLubricant
specificationsin this chapter.
State or local regulations on volatile organic
compounds may restrict the use of methanol, a
common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze
agents should be used only if they provide cold
weather protection without damaging the vehicle’s
paint finish, wiper blades or washer system.
Note:Do not put washer fluid in the engine coolant
reservoir. Washer fluid placed in the cooling system
may harm engine and cooling system components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the
appropriate intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 5 to 10 minutes for
the oil to drain into the oil pan.
3. Set the parking brake and ensure the gearshift is
securely latched in P (Park) (automatic
transmissions) or 1 (First) (manual transmissions).
4. Open the hood. Protect yourself from engine heat.
Maintenance and Specifications

Batteries normally produce explosive gases
which can cause personal injury. Therefore,
do not allow flames, sparks or lighted substances
to come near the battery. When working near the
battery, always shield your face and protect your
eyes. Always provide proper ventilation.
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.
Because your vehicle’s engine is 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) (automatic
transmission) or the neutral position (manual
transmission), turn off all accessories and start the
engine.
Maintenance and Specifications
204

If you use a brake fluid that is not DOT 3,
you will cause permanent damage to your
brakes.
Do not let the reservoir for the master
cylinder run dry. This may cause the brakes
to fail.
CLUTCH ADJUSTMENT (IF EQUIPPED)
Check the clutch
adjustment. Refer to
the scheduled
maintenance guide for
the service interval
schedules.
The clutch on your
vehicle is operated by a
cable. As necessary, adjust the clutch as described
below.
1. Turn the engine off and shift into 1 (First).
2. Put your foot under the clutch pedal and gently
pull it up until the pedal stops.
3. Push the clutch pedal down slowly. You will hear a
click as the clutch adjusts itself.
TRANSMISSION FLUID
Checking automatic transmission fluid
(if equipped)
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
Maintenance and Specifications
228

You can check the fluid without driving if the
ambient temperature is above 10°C (50°F). However,
if fluid is added at this time, an overfill condition
could result when the vehicle reaches normal
operating temperature.
The transmission fluid
should be in this range
if at normal operating
temperature (66°C-77°C [150°F-170°F]).
The transmission fluid
should be in this range
if at ambient
temperature (10°C-35°C[50°F-95°F]).
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 theLubricant
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.

2Rear axle 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. Fill
6 mm to 14 mm (1/4 inch to 9/16 inch) below

3Ensure the correct automatic transmission fluid is
used. Transmission fluid requirements are indicated
on the dipstick or on the dipstick handle. MERCON
and MERCONV are not interchangeable. DO NOT
mix MERCONand MERCONV. Refer to your
scheduled maintenance guide to determine the
correct service interval.
4Indicates 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.
5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
vehicle on a level surface.
