FORD 2002 Explorer v.1 - Manual (Page 161)

The fact that the air curtains did not inflate in a collision does not mean
that something is wrong with the system. Rather, it means the forces
were not of the type sufficient to cause activation. Side air curtains are
designed to inflate in side-impact collisions, not roll-over, rear-impact,
frontal or near-frontal collisions, unless the collision causes sufficient
lateral deceleration.
Several air bag system
components get hot after
inflation. Do not touch them after
inflation.
If the side air curtain has deployed, the air curtain will not
function again. The side air curtain system (including the
A, B and C pillar trim) must be inspected and serviced by a
qualified technician in accordance with the vehicle service
manual. If the air curtain is not replaced, the unrepaired area will
increase the risk of injury in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to the Air bag readiness
section in the Instrumentation chapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light (same light as for front air bag system) will either
flash or stay lit.
• The readiness light will not illuminate immediately after ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a collision.
