Body System (01.00)1-14-2 Workshop Manual May 2007
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.

Engine Assembly (03.00)
Description
The engine is an all aluminium 4.3 litre 90° V8 configuration. The cylinder heads have dual
overhead camshafts and four valves per cylinder. An electronic engine management system
controls the sequential multi-port fuel injection and distributor-less ignition systems.
The engine uses the latest ‘fast-burn’ combustion technology. Heated oxygen sensors monitor the
oxygen content of exhaust gasses . The engine management system uses the oxygen sensor signals
together with other engine information to ‘fine tune ’ fuelling levels and ignition timing. This helps
to achieve the best possible fuel bur n with minimum exhaust emissions.
Inlet camshaft variable timing to impr ove engine performance and emissions.
Inlet manifold is design with tuned length runners to improve volumetric efficiency and
performance.
The engine is fitted with a dry sump to improv e oil pickup during high speed cornering.
The exhaust system has hydroforme d internals with a 4 into 2 into 1 design for improved engine
tuning and lower backpressure. Additional oxygen sensors are placed after the catalysts so that
long term catalyst efficiency can be monitored.
The engine runs on unleaded fuel only.

Lubrication System (03.02)
Dry Sump System
Unlike a wet sump system where oil is stored in the sump, a
dry sump oiling system stores oil in a separate tank, leaving
the sump essentially ‘dry’.
Two internally-mounted pumps, are used to ‘scavenge’ (1)
oil and deliver it to the storage tank, and then deliver (2) the
oil through the engine. The primary advantage of a dry sump system is its ability to
make more power. With very little oil in the sump, the
rotating assembly is not burdened with the weight of excess
oil (windage). The windage tray or screen which serves to
isolate sump oil from the rota
ting assembly, runs the full
length of the sump.This keeps the rotating assembly free of
windage and allows it to spin freely and make more power.
In addition, the extra crankcase vacuum created by the dry
sump pump helps to improve ring seal for additional power
gain.
Other advantages of a dry sump system include increased oil
capacity, more consistent oil pr essure, the ability to easily
add remote coolers, and adjustable oil pressure. And
because the sump does not stor e oil, it can be relatively
shallow in depth to allow lower engine placement for
improved weight distribution and handling.
