Ford Escort (2003 year). Manual — part 39

• Perform all regularly scheduled maintenance items. Follow the

recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.

Conditions
• Heavily loading a vehicle or towing a trailer may reduce fuel economy

at any speed.

• Carrying unnecessary weight may reduce fuel economy (approximately

0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).

• Adding certain accessories to your vehicle (for example bug

deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.

• Using fuel blended with alcohol may lower fuel economy.
• Fuel economy may decrease with lower temperatures during the first

12–16 km(8–10 miles) of driving.

• Driving on flat terrain offers improved fuel economy as compared to

driving on hilly terrain.

• Transmissions give their best fuel economy when operated in the top

cruise gear and with steady pressure on the gas pedal.

• Close windows for high speed driving.

EPA window sticker

Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.

It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)
expected on the vehicle under optimum conditions. Your fuel economy
may vary depending upon the method of operation and conditions.

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:
• Use only the specified fuel listed.
• Avoid running out of fuel.

Maintenance and Specifications

158

• Do not turn off the ignition while your vehicle is moving, especially at

high speeds.

• Have the items listed in your scheduled maintenance guide performed

according to the specified schedule.

The scheduled maintenance items listed in the scheduled maintenance
guide 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.

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.

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 diagnostics system. If your “Check Engine/Service Engine
Soon” light is on, refer to the description in the Warning lights and
chimes section of the Instrument cluster chapter. Your vehicle may not
pass the I/M test with the “Check Engine/Service Engine Soon” light on.

Maintenance and Specifications

159

If the vehicle’s powertrain systemor its battery has just been serviced,
the on-board diagnostics systemis reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics systemfor I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, 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.

CHECKING AND ADDING POWER STEERING FLUID

Check the power steering fluid. Refer to the scheduled maintenance
guide for the service interval schedules. If adding fluid is necessary, use
only MERCON

威 ATF.

1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).

2. While the engine idles, turn the
steering wheel left and right several
times.

3. Turn the engine off.

4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.

5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir.

BRAKE/CLUTCH FLUID RESERVOIR

Brake and clutch systems are supplied from the same reservoir.

Maintenance and Specifications

160

The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range, there is no need to
add fluid. If the fluid levels are
outside of the normal operating range, the performance of your brake
system could be compromised, seek service from your dealer
immediately.

CLUTCH FLUID (IF EQUIPPED)

The clutch master cylinder and
brake master cylinder are part of
the same system; both are refillable
through the brake master cylinder
with brake fluid. For more
information on brake fluid
maintenance, refer to Brake fluid in
this chapter.

Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical if irritation

persists. If taken internally, drink water and induce vomiting. Seek
medical attention immediately.

TRANSMISSION FLUID

Checking automatic transmission fluid

Refer to your scheduled maintenance guide for scheduled intervals for
fluid checks and changes. Your transaxle does not consume fluid.
However, the fluid level should be checked if the transaxle is not working
properly, i.e., if the transaxle slips or shifts slowly or if you notice some
sign of fluid leakage.

Automatictransmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 30 km [20 miles]). If your vehicle has been operated
for an extended period at high speeds, in city traffic during hot
