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.
CAUTION!
Do not damage the sleeve. Otherwise, the
side-air bag cannot be correctly installed to
seat back.
Installation
1) Confirm sleeve (1) is surely installed in side-air bag (inflator) module.
2) Tighten sleeve lock nut (2) to specified torque.
Tightening torque
Sleeve lock nut (a): 2.5 N·m (0.25 kgf-m, 2.0 lb-ft)
3) Install new clip to seat back.
4) Connect side-air bag (inflator) module connector (1) securely as shown in figure.
a) Connect connector.
