FRONT SEAT BELT PRE-TENSIONERFront Seatbelts and Pre-tensioners
The front seatbelts are of the inertia reel type with
integral pre-tensioners and torsion bar load
limiters fitted to the reel assemblies. The lower
anchorage and buckle strap are mounted on the
moving seat slides to maintain optimum belt
geometry. The shoulder anchorage is fixed to the B
post via a four position height adjuster. An
automatic locking retractor (ALR) is incorporated
in the passenger belt reel assembly to provide
child seat security.
A compact type of pre-tensioner is fitted to the
front seatbelt reel assemblies. The reduced size is
achieved by the use of rack and pinion gearing to
retract the seatbelt reel when the unit is fired.
The initiator is a conventional pyrotechnic device
which is electrically triggered from the Restraints
Control Module (RCM).
Fault diagnosis of the pre-tensioner firing circuits
is carried out by the RCM and the presence of a
fault is indicated by the airbag warning lamp (see
Diagnostics).
The pre-tensioner is an integral part of the seatbelt
assembly and is not serviceable. Normal safety
procedures applicable to the handling of
pyrotechnic devices must be followed.
Note that plastic belt guides are fitted to the B
posts: if the pre-tensioners are fired, these guides
will fracture.
Rear Seatbelts
All three rear seatbelts are of the inertia reel type
with child seat automatic locking retractors.
The two outboard retractor assemblies are
mounted on the rear quarter panels. The centre
retractor is reverse wound and mounted in a
recess on the rear parcel shelf.

Airbags
Driver Airbag
The driver airbag module is fitted in the centre of
the steering wheel and is of conventional design.
A reduced charge propellant (Ôde-poweredÕ) is
used to minimise impact effects where the driver
is seated close to the wheel.
The module is secured by two side screws on the
left and right underside of the steering wheel.
Passenger Airbag
WARNING:
Do not place objects on the passenger airbag
deployment panel. Injury could occur if the
airbag contacts an object during inflation.
The passenger airbag uses a heated gas inflator
(HGI) system instead of a solid propellant. This
system is inherently ÔcleanÕ since the inflation gas
is a lean hydrogen/air mixture and the by-
products are water vapour and air. Although the
gas is not classified as an explosive, the possible
effects of accidental deployment when handling
or working close to the unit are similar to those of
other types of airbag. It is recommended that
current safety procedures are also followed when
handling the HGI modules.
The HGI airbag module has fewer components
than previous types, consisting of:

PASSENGER AIRBAG
¥ Aluminium pressure vessel containing a
mixture of 12% hydrogen/88% air at a
pressure of 180 bar.
¥ Pressure vessel end plug with burst disc.
¥ Pyrotechnic igniter assembly fitted to
pressure vessel end plug.
The igniter is electrically triggered from the
Restraints Control Module (RCM). When triggered,
the igniter fires a high speed ÔdartÕ along the
length of the pressurised cylinder, producing a
heated trail (due to friction) which causes rapid
and even combustion of the gas throughout the
cylinder. The igniter also ruptures the burst disc in
the end plug, allowing the expanding gases from

SRS Operation
J.501.940
AIRBAG SYSTEM (LHD) The Supplementary Restraints System (SRS)
provides impact sensing, control of deployment
and fault diagnosis of the control module, airbags,
pretensioners and associated circuits. Most of
these functions are carried out by the Restraints
Control Module (RCM).A front impact triggers the driver and passenger
airbags and both pre-tensioners provided the
impact is above a set threshold as detected by the
two longitudinal sensors in the RCM.
When a side impact occurs, the lateral safing
sensor in the RCM must also agree with an impact

Power Assisted Steering
Introduction
The Jaguar S-TYPE has a variable assist rack and
pinion steering gear and variable rack ratio. The
variable steering rack ratio reduces the number of
turns from lock to lock (2.8) to enhance parking
manoeuvrability whilst maintaining the on-centre
steering precision required at high speed. Full
power assistance is provided for parking. Steering
assistance decreases smoothly at a calibrated rate
to raise driver steering efforts as vehicle speed
increases.
Servicing
There are no carry over parts from XK or XJ Series
vehicles.
The rack is mounted to the rear of cross member
Number 2. The PAS pump is belt driven. A PAS
cooler matrix is located within the radiator
package.
Low PAS pump speeds problems are prevented by
increasing engine speed. A power steering
pressure (PSP) switch senses the demand on the
pump at low engine speeds and increases the
speed to a pre-set minimum.
Hose connections to the pump and the steering
gear are quickfit connectors. The quick connect
tube must be pushed into the existing tube nut
port, along the centreline. The assembly is
complete when the tube end bottoms out in the
port with an audible click/snap. Correct assembly
should be verified by pulling the quickfit tube end.
Servicing of the PAS line involves removal of the
quickfit nut. Replacement PAS lines are supplied
complete with quickfit nut and sealing washer. If
the joint is disturbed it is compulsory to replace
the PTFE sealing ring otherwise leaks are
inevitable. Replacement sealing washers may be
installed with the use of Service tool
D90P-3517-A.
Care must be taken when removing the quickfit
nut from the V6 engine pump as the pulley is
PHENOLIC and is susceptible to damage. The V8
pump installation provides a short jumper tube
from the pump to improve accessibility to the
high-pressure hose connection. The PAS pulley

The driver warning chime provides the driver with
an audible warning for the ignition on, key in
ignition, all doors open and the headlamps on,
hood open, trunk open, lamps on and safety belt
not engaged. A chime will sound every one
second when a fault in the air bag circuit is
detected.
The driver is also provided with a visual message
or warning displayed in the information message
center.
