2) Loosen seat back surface fastener (1) and roll up
backside of seat back surface.
3) Remove sleeve lock nut (1) from side-air bag
(inflator) module (2).
4) Remove side-air bag (inflator) module from seat
back.
5) Disconnect side-air bag (inflator) module connector
(1) as shown in the figure.
a) Unlock lock button (2).
b) With lock button unlocked, disconnect connector.WARNING!
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you.
Never carry air bag (inflator) module by
wires or connector on the side of the
module. In case of an accidental
deployment, the bag will then deploy with
minimal chance of injury.
• As the live side-air bag (inflator) module
must be kept with its bag (trim cover)
facing up while being stored or left
standing. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment.
• Observe “Precautions on Handling and
Storage of Air Bag System Components”
for handling and storing it.
Otherwise, personal injury may result.
