²Adjust tire pressure to recommended specifications found on the Tire
Pressure Label.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control.
Tire rotation
Because your vehicle's tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the ``Service Guide''. If you notice that the tires
wear unevenly, have them checked.
²Four tire rotation
Maintenance and care
179

Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g., ``All Terrain'', etc.),
as originally offered by Ford.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier to lose control and roll
over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
USING SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires and traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or their equivalents. See your
dealer or qualified service technician for more information on tire cables
for your vehicle.
Follow these guidelines when using snow tires and traction devices:
²Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
²Install cables securely, verifying that the cables do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the cables rub or bang against the
vehicle, stop and retighten them. If this does not work, remove the
cables to prevent vehicle damage.
²Avoid overloading your vehicle.
²Remove the tire cables when they are no longer needed.
²Do not use cables on dry roads.
²The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from the vehicle when
using snow tires and traction devices.
²Do not exceed 48 km/h (30 mph) with tire cables on your vehicle.

recommended octane, see your dealer or a qualified service technician to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ``Regular'' gasoline.
``Premium'' gasoline is not recommended (particularly in the United
States) because it may cause these problems to become more
pronounced. If the problems persist, see your dealer or a qualified
service technician.
The American Automobile Manufacturers Association (AAMA) issued a
gasoline specification to provide information on high quality fuels that
optimize the performance of your vehicle. We recommend the use of
gasolines that meet the AAMA specification if they are available.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use a high-quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air quality, including
reformulated gasolines that contain oxygenates up to 10% ethanol or
15% MTBE.
Do not use gasolines containing methanol, which can damage critical fuel
system components. Damage resulting from the use of methanol may not
be covered by your warranty.
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 services listed in your ``Service Guide'' performed according
to the specified schedule.
The Scheduled Maintenance Services listed in the ``Service Guide'' are
required because they are considered 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.
Watch for fluid leaks, strange odors, smoke, loss of oil pressure, the
charging system warning light, the ``Check Engine'' light or the
temperature warning light. These events 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, 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
Maintenance and care
185

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.
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 ``check engine/service
engine soon'' light is on, reference the applicable light description in the
Warning Lights and Chimessection of your owners guide. Your vehicle
may not pass the I/M test with the ``check engine/service engine soon''
light on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ``not ready for I/M test'' condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop and go, city type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.

limited slip differential. If your vehicle is equipped with a limited slip
differential, add 118 ml (4 oz.) of additive friction modifier
C8AZ-19B546-A, Ford specification EST-M2C118±A, for complete refill of
8.8 inch and 9.75 inch rear axles.
3Vehicles equipped with 4.0L SOHC or 4.0L EFI engines and 3.73 or
4.10 rear axle ratios or 5.0L engines require synthetic rear axle lubricant.
Rear axles containing synthetic lubricant are lubricated for life. These
lubricants are not to be checked or changed unless a leak is suspected,
service required or the axle assembly has been submerged in water. The
axle lubricant should be changed any time the axle has been submerged
in water. For Traction-Lok rear axles, add 118 ml (4 oz.) of additive
friction modifier C8AZ-19B546-A, Ford specification EST-M2C118±A,
whenever the lubricant is changed.
4Refer to your ``Service Guide'' for axle fluid change intervals.
