Activation Deactivation
NOTE: When automatic locking retractor is activated, no further webbing
can be drawn from the seatbelt retractor, prior to disengagement of the
automatic locking. This can be mistaken as a jammed seatbelt retractor
Activated by total extraction of the webbing Automatic locking retractor is deactivated by
allowing the webbing to retract until the
clicking stops (close to park position) When activated the automatic locking retractor is identified by a clicking noise
during webbing retraction When deactivated the automatic locking
retractor seatbelt changes state, from a static
seatbelt to an automatic seatbelt Seatbelt Locking Test
With the vehicle stationary and on level ground take firm hold of the seatbelt webbing (on the tongue side of the upper
seatbelt anchor) and withdraw sharply, the retractor should lock. Preventing further webbing release (repeat this test 3
times). Any seatbelt retractor which fails to lock must not be used and a new seatbelt must be installed.

System Operation System Operation
In a collision, the sudden deceleration or acceleration is measured by the impact sensors and the accelerometers in the
restraints control module. The restraints control module evaluates the readings to determine the impact point on the vehicle
and whether the deceleration/acceleration readings exceed the limits for firing any of the airbags, pretensioners, and battery
disconnect unit. During a collision, the restraints control module only fires the airbags and pretensioners if the safing function
confirms that the data from the impact sensor(s) indicates an impact limit has been exceeded.
The RCM incorporates the following impact thresholds to cater for different accident scenarios: Front impact, pretensioners
Front impact, driver and passenger airbags stage 1, belt unfastened
Front impact, driver and passenger airbags stage 1, belt fastened
Front impact, driver and passenger airbags stage 2, belt unfastened
Front impact, driver and passenger airbags stage 2, belt fastened
Rear impact
Driver side impact
Passenger side impact.
The front impact thresholds increase in severity from pretensioners to driver and passenger airbag stage 2, belt fastened (refer
to list above).
Firing Strategies
The safety belt pretensioners are fired when the pretensioner impact limit is exceeded. The RCM only fires the pretensioners if the related safety belt is fastened.
The driver and passenger airbags are only fired in a frontal impact. If an impact exceeds a stage 1 limit, but is less than the
corresponding stage 2 limit, only one inflator in each airbag is fired (stage 2 is still fired for disposal after a delay of 100ms).
If an impact exceeds the stage 2 limit, the two inflators in each airbag are fired simultaneously.
The passenger airbag is disabled unless the front passenger seat is occupied by a large person (NAS only), or the passenger
airbag deactivation switch is on (all except NAS & AUS).
The stage 2 inflator of the driver airbag is disabled if the driver seat is forward of the switching point of the seat position
sensor.
If there is a fault with a safety belt buckle sensor, the RCM assumes the related safety belt is fastened for the pretensioner firing strategy and unfastened for the driver and passenger airbag firing strategies. If there is a fault with the occupant
classification sensor, the RCM disables the passenger airbag. If there is a fault with the passenger airbag deactivation switch, the RCM disables the passenger airbag.
If a side impact limit is exceeded, the RCM fires the side airbag and the side head airbag on that side of the vehicle. If the side impact limit on the front passenger side of the vehicle is exceeded, the RCM also evaluates the input from the occupant classification sensor, and fires the side airbag only if the front passenger seat is occupied by a large person (NAS only).
If multiple impacts occur during a crash event, after responding to the primary impact the RCM will output the appropriate fire signals in response to any further impacts if unfired units are available.

Measuring options
Comparison measurements can also be made on the outside of the body. Depending on the damage, comparison
measurements and diagonal measurements can be carried out using compass, telescopic rod, tape measure or ruler.
NOTE: The same reference points must be chosen on both sides when checking for changed dimensions (e.g.
bores, edges, beads/swage lines etc).
All of the important external body dimensions are listed in Tolerance Checks.
For additional information, refer to: Body and Frame (501-26 Body Repairs - Vehicle Specific Information and Tolerance Checks, Description and Operation).
Measurements with a measuring/straightening jig.
A measuring/straightening jig is required for accurate measurements of the body. The measuring systems are
categorised by their means of operation:
Mechanical measuring system.
Optical measuring system.
Quick and accurate measuring results can be obtained using computerised measuring systems.
A minimum of three intact measuring points on the body are required for measurements of length, width and height
dimensions.
In some cases this may mean making the measuring points accessible. All of these measuring systems can be used to make
body measurements, provided all the equipment is available.
Planning a repair
The following decisions have to be made before the repairs are started:
Does the vehicle need to be put on a straightening jig, or can it be straightened by other means?
Does the body need to be measured?
Do aggregates like engine or axles need to be removed? Impact energy is transferred via the side member to the A-pillar
