mounted onto a spindle (torsion bar) which once the sensor
has locked the retractor reel and a predetermined load is
applied, twists and allows additional webbing into the
system. The deceleration force required to initiate this
sequence is approximately th e same as that required to
initiate airbag deployment. The torsion bar load limiting
device will only react if the safety belt is in use at the time of
the impact.
Emergency Locking Retractor (ELR)
The retractors in all seat posi tions feature ELR. During any
period of sudden deceleration, or under lateral load when
cornering at speed, a sensor weight within the safety belt
retractor moves a locking pawl against the teeth on the
retractor reel, which then locks the retractor preventing any
further release of webbing. As soon as the load applied onto
the retractor through the safety belt webbing is removed the
locking pawl releases the retractor reel and normal
movement is returned to the retractor.
Automatic Locking Retractor (ALR)
Automatic locking retractors (ALR) are installed to all
passenger seat positions.
The safety belt webbing on these are clearly marked to show
their operating feature. To initiate the ALR system, fasten the
safety belt into it’s buckle and pull all of the webbing from
the retractor, as the safety belt is released the retractor locks
allowing travel in only one plane thus producing a fixed
length restraint and preventing the safety belt from
introducing slack, making any child seat it may be restraining
secure. The ALR system of the retractor is disengaged by
releasing the safety belt and allowing the safety belt to fully
retract onto the reel. Caution
It should be considered th at during any event that
utilizes the full capability of the safety belts, the
webbing may have been elongated and the torsion bar may have twisted. For this reason, if a vehicle is
involved in an accident which results in the deployment of the airbag(s), all the safety belts that were in use at
the time of the accident MUST be renewed.

event that does not. The RCM governs the operation of the
whole system and performs continual system diagnostics.
Information on the severity of an impact is received from the
impact sensors.
Variations in the deployment of the front airbag modules are
dependent on the status of the front safety belt buckles.
Dual Inflation Technology
When activated, the airbags will deploy at either a normal or
reduced level of inflation, depending on crash severity.
Various sensors determine the direction and severity of an
impact. The system analyses this information then deploys
the appropriate airbags.
Impact Sensors
Side Impact - Side impact sensors are mounted to the base
of each B-pillar and within each door. In the event of a side
impact, the RCM processes the impact data sent by the side
impact sensor against stored data. The RCM will deploy the
side airbag on the side the deployment request was initiated
and the seat belt pretensioner.
Front Impact - Front impact sensors (x2) are located under
the grill opening panel.
The SRS module processes the impact data sent by the front
impact sensor against stored data, and deploys the front
airbags, and the seat belt pretensioners.
Passenger Airbag Deactivation
The passenger airbag can be deactivated using the PAD
(Passenger Airbag Deactivation) switch. Switching the
passenger airbag off allows children under the age of 12 to
be carried safely in the passenger seat. The PAD switch is
located at the passenger end of the instrument panel and is
accessible when the pa ssenger door is open.
Maintenance
Driver’s Airbag Module - Renew
Removal
1. Disconnect vehicle battery.
2. Allow a two minute power down period to de-activate
airbag system.
3. Rotate steering wheel to access and remove bolts (x2) from driver's airbag module to steering wheel (see
Figure 1).
4. Release driver's airbag mo dule, disconnect multiplugs
(x2) and remove airbag module (see Figure 2).
Installation
1. Position driver's airbag mo dule and connect multiplugs
(x2).
2. Install bolts (x2) and tighten.
3. Connect vehicle battery.
LH Front Seat Belt - Renew
Removal
1. Remove front seat (see Workshop Manual procedure 01.10.AB Seat Assembly - Front - LH - Remove for
Access and Refit).
Note
Please see the Owner’s Guid e for the full deactivation
procedure.
Warning
Unnecessary deactivation of the passenger airbag is
dangerous. The passenger will not receive the added
protection from the airbag and serious injuries or even
death could occur. With the exception of installing a child seat on the passenge r seat, do not turn the
passenger airbag deactiva tion switch to the off
position.
Warning
Never place a child in a child seat or on a booster
cushion in the passenger seat if the airbag is active.
