SERVICE RECOMMENDATIONS
To help you service your vehicle:
•We highlight do-it-yourself items in the engine compartment for easy
location.
•We provide a scheduled maintenance guide which makes tracking
routine service easy.
If your vehicle requires professional service, your dealership can provide
the necessary parts and service. Check yourWarranty Guideto find out
which parts and services are covered.
Use only recommended fuels, lubricants, fluids and service parts
conforming to specifications. Motorcraft parts are designed and built to
provide the best performance in your vehicle.
PRECAUTIONS WHEN SERVICING YOUR VEHICLE
Be especially careful when inspecting or servicing your vehicle.
•Do not work on a hot engine.
•When the engine is running, keep loose clothing, jewelry or long hair
away from moving parts.
•Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
•Keep all lit cigarettes, open flames and other lit material away from
the battery and all fuel related parts.
If you disconnect the battery, the engine must “relearn” its idle
conditions before your vehicle will drive properly, as explained in the
Batterysection in this chapter.
