SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information Decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 160 930 km (100 000 miles) should be
continued as before 160 930 km (100 000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habits frequently include one or more the following
conditions:
• Short trips of less than 16 km (ten miles) when outside temperatures
remain below freezing.
• Operating during hot weather in stop-and-go “rush hour” traffic.
• Operating in severe dust conditions.
• Extensive idling, or low speed operation such as door-to-door delivery
service.
• High speed operation with a fully loaded vehicle (max. GVW).
• Snowplowing.
Perform the following:

miles) or 125 hours of engine service.
• If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.

(30 000 miles) or 6 months, whichever comes first.
