Your vehicle's coolant protects your engine from
overheating in the summer and from freezing in
the winter. Check the level of the coolant at least
once a month. Simply look at the engine coolant
reservoir located in the engine compartment. To
locate the reservoir, see the diagram of your
vehicle's engine underEngine Type, in this
chapter.

Information About Tire Quality Grades
*
[MC27500( ALL)01/96]
New vehicles are fitted with tires that have their
Tire Quality Grade (described below) molded
into the tire's sidewall. These Tire Quality
Grades are determined by standards that the
United States Department of Transportation has
set.
*
[MC27600( ALL)01/96]
Tire Quality Grades apply to new pneumatic
tires for use on passenger cars. They do not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires
with nominal rim diameters of 10 to 12 inches or
limited production tires as defined in Title 49
Code of Federal Regulations Part 575.104(c)(2).

as the government has written it.

[MC27800( ALL)01/96]
Treadwear
*
[MC27900( ALL)01/96]
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half (1 1/2)
times as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.

Emission Control System
*
[MC36600( ALL)01/96]
Your vehicle is equipped with a catalytic
converter which enables your vehicle to comply
with applicable exhaust emission requirements.
*
[MC36700( ALL)05/96]
RWARNING
Exhaust leaks may result in the entry of
harmful and potentially lethal fumes into
the passenger compartment. Under
extreme conditions excessive exhaust
temperatures could damage the fuel
system, the interior floor covering, or
other vehicle components, possibly
causing a fire.
*
[MC36800( ALL)01/96]
To make sure that the catalytic converter and the
other emission control parts continue to work
properly:
*
[MC36900( ALL)01/96]
q
Use only unleaded fuel.
*
[MC37000( ALL)01/96]
q
Avoid running out of fuel.

maintenance services are required because
they are considered essential to the life and
performance of your vehicle and to its
emissions system.

242any automotive repair establishment or
individual using automotive parts equivalent to
those which your vehicle or engine was
originally equipped.
*
[MC37500( ALL)01/96]
Ford strongly recommends the use of genuine
Ford replacement parts. If other than Ford or
Motorcraft parts or Ford authorized
remanufactured parts are used for maintenance
replacements or for the service of components
affecting emission control, such non-Ford parts
should be equivalent to genuine Ford Motor
Company parts in performance and durability. It
is the owner's responsibility to determine the
equivalency of such parts. Please consult your
warranty booklet for complete warranty
information.
*
[MC37600( ALL)01/96]
RWARNING
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.
*
[MC37700( ALL)01/96]
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
*
[MC37800( ALL)01/96]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.

By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device

United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.

Never use a metal exhaust collector when you
service your vehicle. If the metal collector
contacts any of your vehicle's plastic trim or
bumper parts they could melt or deform.

In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. 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 testing condition. To
prepare for I/M testing, the law specifies that
additional city and highway driving is necessary
to complete the check of the OBD II system.
