How Does the Air Bag Supplemental Restraint System
Work?
[SS12750(R)01/96]
The Air Bag Supplemental Restraint System consists of the
driver air bag, passenger air bag (if equipped), impact sensors, a
system diagnostic module, a readiness light and tone, and the
electrical wiring which connects the components.

[SS12900(R)01/96]
The driver air bag is in the center of the steering wheel. The
right front passenger seat air bag (if equipped) is in the upper
right hand section of the instrument panel ledge above the
glove compartment.
*
[SS13010(R)05/96]
If a collision occurs, the sensors sense the severity of the impact
and activate the air bags if necessary. The air bag system is
designed to deploy in frontal and front-angled collisions more
severe than hitting a parked vehicle (of similar size and weight)
head-on at about 28 mph (45 km/h). Because the system senses
the crash severity rather than vehicle speed, some frontal
collisions at speeds above 28 mph (45 km/h) will not inflate the
air bag.
*
[SS13020(R)05/96]
When the sensors activate the system, the air bags inflate
rapidly, filling with non-toxic nitrogen gas in a fraction of a
second. Immediately after inflation, the air bags deflate by
releasing the nitrogen gas through vent holes. The whole
process takes place in a matter of seconds.
[SS13025(R)05/96]
RWARNING
Do not place objects or mount equipment on or near the
air bag cover on the steering wheel or in front seat areas
that may come in contact with a deploying air bag.
Failure to follow this instruction may increase the risk of
personal injury in the event of a collision.
*
[SS13030(R)05/96]
RWARNING
Several air bag system components get hot after inflation.
Do not try to touch them after inflation.

Brakes

[GF00200(R)01/96]
Front Disc Brakes
*
[GF00210(R)01/96]
The front disc brakes are self-adjusting. They do not require
service other than periodic inspection for pad wear.
*
[GF00270(R)03/96]
Rear Drum Brakes
*
[GF00274(R)03/96]
The rear drum brakes are self-adjusting. Automatic adjustment
occurs when the brakes are applied while ªbacking up.º If
normal operation does not include much backing, adjust the
brakes when they seem ªlow,º using the procedure underIf
Brakes Do Not Grip Well or Pedal is ªLowºin this chapter.
*
[GF00300(R)01/96]
Hydraulic Power Brakes
[GF00310(R)01/96]
The hydraulic brake system is made up of two independent
hydraulic circuits. One hydraulic circuit supplies fluid to the
front disc brakes and the other hydraulic circuit supplies fluid
to the rear drum or disc brakes. These two circuits are supplied
by a common hydraulic brake fluid reservoir, with a fluid level
sensor.
[GF01010( ALL)03/97]
Occasional brake noise is normal and does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or
intermittent squeal or groan noises when the brakes are applied.
Such noises are usually heard during the first few brake
applications in the morning; however, they may be heard at any
time while braking and can be aggravated by environmental
conditions such as cold, heat, moisture, road dust, salt or mud.
If a ªmetal-to-metalº or ªcontinuous grindingº sound is present
while braking, the brake linings may be worn-out and should be
inspected by a qualified service technician.
*
[GF00312(R)01/96]
The brake light in the instrument cluster will light for low brake
fluid in the common brake fluid reservoir.

Automatic Transmission Operation
(4R44E/5R55E)
[GF08715(R)05/96]
If your vehicle is equipped with an automatic transmission, it
will be either a four speed overdrive transmission (4R44E) or a
five speed overdrive transmission (5R55E). All 2.3L and 3.0L
engines use the 4R44E transmission, while all 4.0L engines use
the 5R55E transmission. Both transmission types have a lockup
torque converter. Transmission operation is controlled by the
Powertrain Control Module (PCM).
*
[GF08720(R)01/96]
The PCM will automatically adjust transmission operation to
make up for varying conditions. Several sensors located on the
engine and transmission such as throttle position, engine speed,
vehicle speed and transmission temperature are used by the
PCM to shift the transmission into a higher or lower gear when
required for the best performance and fuel economy. For
example, you may notice that the transmission will upshift to a
higher gear more quickly when the vehicle has not reached
normal operating temperature.
*
[GF08730(R)01/96]
The PCM also controls the transmission's Torque Converter
Clutch (TCC) to further raise vehicle performance and fuel
economy. The TCC will engage when the transmission operating
temperature and other conditions determined by the PCM have
been met. Engagement of the clutch may be noted as a decrease
in engine speed.
[GF08740(R)05/96]
To help in troubleshooting, the PCM continually performs
self-tests on the electronic control system and, if any faults are
detected, stores them in memory. The Transmission Control
Indicator Light (TCIL) (O/D OFF), which is located on the
instrument cluster, may flash steadily if a malfunction has been
detected. If the TCIL is flashing, contact your Ford dealer as
soon as possible. If this condition persists, damage to the
transmission could occur.
