If other than Ford, Motorcraft or Ford-authorized parts are used for

maintenance replacements or for service of components affecting

emission control, such non-Ford parts should be equivalent to genuine

Ford Motor Company parts in performance and durability.

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 the “Service Engine Soon” light, 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.

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 identifies engine displacement and gives some tune up

specifications.

Please consult your Warranty Guide for 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). This OBD-II system protects the

environment by ensuring that your vehicle continues to meet

government emission standards. The OBD-II system also assists the

service technician in properly servicing your vehicle. When the Check

Engine/Service Engine Soon light illuminates, the OBD-II system has

detected a malfunction. Temporary malfunctions may cause your Check

Engine/Service Engine Soon light 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.
