1998 FORD ESCORT service

technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting,
rough idle or hesitation problems
try a different brand of fuel. If the
condition persists, 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.
Running out of fuel
Avoid running out fuel because this
situation may have an adverse
Maintenance and care
158

affect on modern powertrain
components.
You may need to crank the engine
several times before the system
starts to pump fuel from the tank
to the engine. If you run out of
fuel, your Service Engine Soon
light may come on. For more
information on the Service Engine
Soon light, refer to the
Instrumentationchapter.
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
ªService Guideº performed
according to the specified
schedule.
The Scheduled Maintenance
Services listed in the ªService
Guideº 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.
Maintenance and care
160

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 ªService Engine Soonº 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 the
Vehicle Emission Control
Information Decal located on or
near the engine. This decal
identifies engine displacement and
gives some tune up specifications.
Maintenance and care
161

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, reference the applicable light
description in theWarning Lights
and Chimessection of your
owners guide. Your vehicle may
not pass the I/M test with the
ªcheck engine/service engine soonº
light on.
If the vehicle's powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a ªnot ready for I/M testº
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.

AIMING THE HEADLAMPS
Your vehicle is equipped with a
Vehicle Headlamp Aim Device
(VHAD) on each headlamp. Each
headlamp may be properly aimed
in the vertical (up/down) and the
horizontal (left/right) directions
using your VHAD system. The
headlamps on your vehicle are
properly aimed at the assembly
plant, and vertical and horizontal
indicators of the VHAD system are
calibrated.
A bubble (vertical indicator) that
is not centered between the two
red lines does not necessarily
indicate out-of-aim headlamps. If
your vehicle is not positioned on a
level surface, the slope will be

included in the vertical indication.
Therefore, vertical and horizontal
headlamp adjustment should be
performed only when the beam
direction appears to be incorrect.
You will need one 4 mm wrench or
socket with ratchet to make the
adjustments.
The following procedure assumes
that the factory set horizontal
indicator reference has not
changed and the vehicle's front
structure is in its factory alignment
condition. If the vehicle has been
in an accident requiring the front
end of the vehicle to be repaired,
the horizontal indicator should be
recalibrated by the servicing
facility according to instructions in
the vehicle's Service Manual.
Horizontal aim adjustment
1. With the hood open, locate the
horizontal indicator and adjusting
screw. They are located below the
viewing window at the rear of the
headlamp assembly.
