Safety belt extension assembly
If the safety belt is too short when fully extended, there is a 8 inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat LATCH and tether anchors, and attaching
hardware, should be inspected after a collision. Ford Motor Company
recommends that all safety belt assemblies in use in vehicles involved in
a collision be replaced. However, if the collision was minor and your
authorized dealer finds that the belts do not show damage and continue
to operate properly, they do not need to be replaced. Safety belt
assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
For proper care of soiled safety belts, refer toInteriorin theCleaning
chapter.

•Snowplowing with vehicles equipped with a diesel engine may result in
engine overheating in highway driving with snowplow blade raised
unless equipped with the special engine cooling fan clutch that is
included with a snow plow package option.
Operating the vehicle with the snowplow attached
Do not use your vehicle for snow removal until it has been driven at
least 500 miles (800 km).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature: Attention to engine
temperature is especially important when outside temperatures are
above freezing. Angle the blade to maximize airflow to the radiator and
monitor engine temperature to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in yourscheduled maintenance
informationfor engine oil and transmission fluid change intervals.
Snowplowing with your airbag-equipped vehicle
Your vehicle is equipped with a driver and passenger airbag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the airbag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible airbag deployment.
Do not attempt to service, repair, or modify the air bag
supplemental restraint system (SRS) or its fuses. See your Ford
or Lincoln Mercury dealer.

Engine oil and filter recommendations
Look for this certification
trademark.
Use SAE 5W-20 engine oil
Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.
To protect your engine’s warranty use Motorcraft SAE 5W-20 or an
equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A.
SAE 5W-20 oil provides optimum fuel economy and durability
performance meeting all requirements for your vehicle’s engine.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed in thescheduled maintenance information.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter or
another with equivalent performance for your engine application.
