Emission Control System
*
[MC38505(ALL)01/96]
Your vehicle is equipped with a catalytic converter which
enables your vehicle to comply with applicable exhaust emission
requirements.
*
[MC38510(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.
[MC38515(ALL)05/96]
Malfunctions in the engine or exhaust system can result in
excessive exhaust system temperatures. Under extreme
conditions (for example, towing a trailer up a steep hill on a
very hot day with a malfunctioning engine or exhaust system),
high exhaust system temperatures could be damaging.
*
[MC38525(ALL)01/96]
To make sure that the catalytic converter and the other emission
control parts continue to work properly:
*
[MC38530(ALL)01/96]
n
Use only unleaded fuel.
*
[MC38535(ALL)01/96]
n
Avoid running out of fuel.
*
[MC38540(ALL)01/96]
n
Never turn off the ignition while your vehicle is moving,
especially at high speeds.
*
[MC38545(ALL)03/96]
n
Have the services listed in yourMaintenance Schedulebooklet
performed according to the specified schedule.
*
[MC38550(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.

Maintenance and Care

[MC38555(ALL)01/96]
RWARNING
Do not remove the floor carpet in your vehicle. Emission
controls cause high exhaust temperatures under the floor.
*
[MC38560(ALL)01/96]
Watch for fluid leaks, strange odors, smoke and loss of oil
pressure. Also watch for the charge warning light, the check
engine light, or the temperature warning light. These sometimes
indicate that the emission system is not working properly.
*
[MC38565(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.

In general, maintenance, replacement, or service of the emission
control devices or systems in your new Ford Motor Company
vehicle or engine may be performed at your expense by any
automotive repair establishment or individual using automotive
parts equivalent to those with which your vehicle or engine was
originally equipped.
*
[MC38575(ALL)01/96]
By law, anyone who manufactures, repairs, services, sells, leases
vehicles, trades vehicles, or supervises a fleet of vehicles is not
permitted to intentionally remove an emission control device or
prevent it from working. In some of the United States and in
Canada, vehicle owners may be liable if their emission control
device is removed or is prevented from working.
*
[MC38580(ALL)01/96]
Do not drive your vehicle if it does not operate properly. See
your dealer if the engine runs on for more than five seconds
after you shut it off or if it misfires, surges, stalls, or backfires.
*
[MC38585(ALL)01/96]
Information about your vehicle's emissions control 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.

How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
*
[MC38595(ALL)05/96]
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 mixed city and highway driving is
required to complete the check of the OBD II system.
*
[MC38602(ALL)03/96]
The driving modes required to reach the ready condition consist
of a minimum of 30 minutes of city and highway driving as
described below.
*
[MC38607(ALL)03/96]
n
20 minutes of driving in stop and go city-type traffic with at
least four idle periods.
*
[MC38612(ALL)03/96]
n
10 minutes of driving on an expressway or highway.
*
[MC38617(ALL)05/96]
Before completing the above driving modes, the engine must be
warmed up and at operating temperature. Once started, the
vehicle must not be turned off during the above driving modes.
If the vehicle owner is unable to meet the I/M requirements by
using these driving patterns, an authorized service center can
perform a detailed OBD II drive cycle as it would any other
type of repair work.

Headlamp Bulb
*
[MC40000(ALL)03/96]
The headlamps on your vehicle use replaceable bulbs. When the
lamp burns out, simply replace the bulb, rather than the whole
lamp.
*
[MC40100(ALL)01/96]
RWARNING
Handle a halogen headlamp bulb carefully and keep out
of children's reach. Grasp the bulb only by its plastic
base and do not touch the glass. The oil from your hand
could cause the bulb to break the next time the
headlamps are operated.
*
[MC40200(ALL)01/96]
Do not remove the burned out bulb unless you can immediately
replace it with a new one. If a bulb is removed for an extended
period of time, contaminants may enter the headlamp and affect
its performance.
