HAZARD LIGHTS CONTROL
Use only in an emergency to warn traffic of vehicle breakdown,
approaching danger, etc. The hazard flashers can be operated when the
ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn the
flashers off.
FUEL PUMP SHUT-OFF SWITCH
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated. The shut-off switch is a device
intended to stop the electric fuel pump when your vehicle has been
involved in a substantial jolt.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in the button on the switch.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

SERVICE RECOMMENDATIONS
To help you service your vehicle:
²We highlight do-it-yourself items in the engine compartment for easy
location.
²We provide a ªService Guideº which makes tracking routine service
easy.
If your vehicle requires professional service, your dealership can provide
necessary parts and service. Check your ªWarranty Guideº to 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.
²Do not work on a hot engine.
²When the engine is running, avoid wearing loose clothing, jewelry or
long hair that could get caught up in moving parts.
²Do not work on a vehicle with the engine running in an enclosed
space, unless you are sure you have enough ventilation.
²Keep 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 ªrelearnº its idle
conditions before your vehicle will drive properly, as explained in the
Batterysection in this chapter.
Working with the engine off
1. Set the parking brake and ensure the gearshift is securely latched in
P (Park).
2. Turn off the engine and remove the key.
3. Block the wheels to prevent the vehicle from moving unexpectedly.
Maintenance and care
109

2. Visually inspect the fluid level.
3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.
If you use a brake fluid that is not DOT 3, you will cause
permanent damage to your brakes.
Do not let the reservoir for the master cylinder run dry. This
may cause the brakes to fail.
WINDSHIELD WASHER FLUID
Checking and adding washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Do not put engine coolant in the container for the windshield
washer fluid.

How fail-safe cooling works
²Standard cluster
²Optional cluster
If the engine overheats, the engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs:
²if your vehicle is equipped with analog gauges, the engine coolant
temperature gauge will move to the H (hot) area
²if your vehicle is equipped with digital gauges, the engine coolant
temperature gauge will illuminate all eight bars and a tone will sound
every five seconds for a minute
²the
symbol will illuminate
²theCheck Engineindicator light will illuminate.
The vehicle will still operate, however:
²the engine power will be limited.
²the air conditioning system will be disabled.
Continued operation will increase the engine temperature:

Running out of fuel
Avoid running out fuel because this situation may have an adverse affect
on powertrain components.
If you have run out of fuel:
²You may need to crank the engine several times before the system
starts to pump fuel from the tank to the engine.
²Your ªCheck Engineº light may come on. For more information on the
ªCheck Engineº light, refer to theInstrumentationchapter.
Calculating fuel economy
To accurately calculate your vehicle's fuel economy:
1. Fill the tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five fuel tank fill-ups, fill the fuel tank and
record the current mileage reading.
4. Use one of the following equations to calculate fuel economy.
Liters used x 1004Total kilometers traveled
Total miles traveled4Total gallons used
Keep a record for at least one month. This will provide an accurate
estimate of the vehicle's fuel economy.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your ªService Guideº performed according to
the specified schedule.
Maintenance and care
134

The scheduled maintenance items listed in the ªService Guideº are
essential to the life and performance of your vehicle and to its emissions
system.
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.
Lumination of the charging system warning light, ªCheck Engineº light or
the temperature warning light, fluid leaks, strange odors, smoke or loss
of oil pressure, could indicate that the emission control system is not
working properly.
If you smell exhaust fumes of any kind inside your vehicle, have
the dealer inspect and fix your vehicle immediately. Do not drive
if you smell exhaust fumes. These fumes are harmful and could kill
you.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, items, 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 ªWarranty Guideº for complete emission warranty
information.
Readiness for inspection/maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostic (OBD-II) system. If your ªCheck Engine/Service
Engine Soonº light is on, refer to the description in theWarning Lights
and Chimessection of theInstrumentationchapter. Your vehicle may
not pass the I/M test with the ªCheck Engine/Service Engine Soonº light
on.
