Crash Sensors And Airbag Indicator - Ford FIESTA Owner's Manual

Supplementary Restraints System
CRASH SENSORS AND
AIRBAG INDICATOR
WARNING
Modifying or adding equipment to
the front end of the vehicle (including
frame, bumper, front end body
structure and tow hooks) may affect the
performance of the airbag system,
increasing the risk of injury. Do not modify
the front end of the vehicle.
The vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module which deploys (activates) the
front safety belt pretensioners, driver
airbag, passenger airbag, knee airbag(s),
seat mounted side airbags, and the side
curtain airbags. Based on the type of crash
(frontal impact or side impact), the
restraints control module will deploy the
appropriate safety devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The readiness light will not
illuminate immediately after the
ignition is turned on.
• The readiness light will either flash or
stay lit.
• A series of five beeps will be heard. The
tone pattern will repeat periodically
until the problem, the light or both are
repaired.

If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The safety belt pretensioners and the front
airbag supplemental restraint system are
designed to activate when the vehicle
sustains longitudinal deceleration
sufficient to cause the restraints control
module to deploy a safety device.
The fact that the safety belt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts) unless the crash causes
sufficient longitudinal deceleration.
• The design of the safety belt
pretensioners is to activate in frontal
and near-frontal crashes, and may also
activate when a side curtain deploys.
• The driver's knee airbag may deploy
based on crash severity and occupant
conditions.
