WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
Illumination of theService engine soon
indicator, charging system
warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power could indicate that the emission control
system is not working properly.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
WARNING:Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult yourWarranty Guide/Customer Information Guidefor
complete emission warranty information.
On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the On
Board Diagnostics System (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. When theService
engine soon
indicator illuminates, the OBD-II system has detected
a malfunction. Temporary malfunctions may cause theService engine
soon
indicator to illuminate. Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
4. Driving through deep water—the electrical system may be wet.

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to thescheduled maintenance informationfor
maintenance intervals. If the original universal joints are replaced with
universal joints equipped with grease fittings, lubrication will also be
necessary.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to yourscheduled maintenance informationfor 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 until it is at normal operating
temperature (approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about
30 minutes to allow fluid to cool before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
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 toIdentifying 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.

1Add the coolant type originally equipped in your vehicle.2Use 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.3Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size, if equipped with an
in-tank cooler, if equipped with an oil to air cooler and if equipped with a remote filter assembly. The amount of
transmission fluid and fluid level should be set by the indication on the dipstick’s normal operating range.4Automatic transmissions that require MERCONV should only use MERCONV fluid. Refer toscheduled
maintenance informationto determine the correct service interval. Use of any fluid other than the recommended
fluid may cause transmission damage.
Automatic transmissions that require MERCONSP should only use MERCONSP fluid. Use of a dual usage fluid in
an automatic transmission requiring MERCONSP may cause transmission damage. Refer toscheduled
maintenance informationto determine the correct service interval. Use of any fluid other than the recommended
fluid may cause transmission damage.5Dana limited-slip axle (M60) requires 8 oz. (228 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford
specification EST-M2C118-A.6If your vehicle’s rear axle is filled with a synthetic rear axle lubricant it 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.7Fill Dana rear axles to 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.8Optional fuel tank 55.0 gallons (208.0L).
