The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
POWER STEERING FLUID
Check the power steering fluid. Refer to scheduled maintenance
information. If adding fluid is necessary, use only MERCON AT F.
• Gasoline engine shown; diesel
engine similar. Refer to
Identifying components in the
engine compartment in the 6.0
and 6.4 Liter Power Stroke
Direct Injection Turbo Diesel
Owner Guide Supplement.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Check the fluid level in the reservoir. It should be between the MIN
and MAX range. Do not add fluid if the level is within this range.
2. If the fluid level is low. Add fluid to bring fluid level up to be between
the MIN and MAX range.
3. Start the engine.
4. While the engine idles, turn the steering wheel left and right several
times.
5. Turn the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is
between the MIN and MAX range.Maintenance and Specifications

2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer to Identifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated area for normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the ambient temperature is
above 50°F (10°C).
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 150°F-170°F (66°C-77°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
You can check the fluid without driving if the ambient temperature is
above 50°F (10°C). 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 (150°F-170°F
[66°C-77°C]).
The transmission fluid should be in
this range if at ambient temperature
(50°F-95°F [10°C-35°C]). Maintenance and Specifications

1Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification
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 your scheduled maintenance information to determine the
correct service interval.
Automatic transmissions that require MERCON LV should only use MERCON LV fluid.
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.Maintenance and Specifications
