appears, you should change the rear axle
fluid at the next convenient time. The
wrench warning indicator turns off when
you switch off your vehicle.

If you use your vehicle extensively at a
racetrack or at high rpm, it is possible to
exceed the service life of the engine timing
chain. A wrench indicator light will
illuminate when it is time for you to replace
your chain. See an authorized dealer. California Fuel Filter Replacement

California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
