Introduction
The Jaguar S-TYPE is an all-new, luxury sports sedan with a distinctive style, refined power, agile
handling, supple ride and luxurious comfort.
Powertrains are a V8 (AJ28) petrol engine, derived from the engines currently used in XJ and XK Series
vehicles, with a new five-speed automatic transmission or alternatively, a V6 (AJ-V6) petrol engine
coupled with either a five-speed automatic transmission or a five-speed manual transmission. The new
V6 engine and transmission units and the updated variations to the V8 engine are described in the
ÔJaguar S-TYPE Powertrain IntroductionÕ Technical Guide, which compliments this Guide.
As with current vehicles, variable rate steering control is fitted and all vehicles have ABS brakes with
traction control as standard. A new, optional feature with the Jaguar S-TYPE is Dynamic Stability Control
(DSC), yaw control, which assists the driver in maintaining directional control of the vehicle.
Unlike current vehicles, the hood is hinged at its rear with a safety catch provided at the front of the
hood. A tilt and slide sliding roof with a sunshade is an optional feature.
Both front seats have electrically operated 8-way adjustments as standard and memory equipment is
available as an option. To allow a greater load to be carried in the luggage compartment, the rear seats
can be folded forwards and are split in a 60/40 configuration.
Automatic climate control, with dual temperature control for the driver and front passenger, is a
standard feature on all vehicles. Another new item is reverse park control, a system giving the driver
audible warning of obstructions which could damage the vehicle during reversing.
A standard fit radio/cassette unit provides in-car entertainment with a CD autochanger also being
offered. Other options include a phone, navigation system, vehicle emergency monitoring system and
certain voice activated systems. Optional cruise control and audio switches are fitted to the steering
wheel. All vehicles have a trip computer system and a message center.
Security features are immobiliser and alarm. Optional features include intruder sensor and inclination
sensor. The 3 or 4 button key-ring transmitter has radio frequency operation with an encrypted rolling
code to help prevent theft of the vehicle.
Standard Corporate Protocol (SCP) is the only computer system highway for all the vehicle electronic
controls, CAN is not used.

Front Fenders and Bumpers
Unique fenders with one style to all markets
incorporating side markers/repeaters.
Front bumper covers are single piece, body
coloured, flexible, low speed impact resistance
(5 mph/8km/h) with a steel beam, attached to the
cross rails and integral grille assembly. The front
bumper has an energy absorbing foam core and
includes provision for air ducts for brake cooling
and telescopic nozzles for headlamp power wash.
Chromed bumper blades and provision for front
fog lamps (or blanking plates), are included. All
vehicles have a removable front splitter vane.
Care is required when refitting the bumper to
ensure correct alignment.
Rear Fenders and Bumpers
The bumper beam is an aluminium extrusion,
mounted to rear rail brackets (5mph (8km/h)
bumper system).
As with the front bumper it has compression
moulded polypropylene foam and is colour keyed
with chromed inserts.
Reverse Park Control system, assisting the driver in
reversing manoeuvres, operates through four
sensors, bumper mounted, at the rear of the
vehicle. The system provides audible warnings to
indicate the distance to an object behind the
vehicle (see Electrical/Electronic section).

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:

¥ 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

Restraints Control Module (RCM)
The RCM:
¥ Houses the electro-mechanical safing sensor
and electronic discrimination sensor which
detect a frontal impact.
¥ Houses the electronic safing sensor to detect
a side impact.
¥ Identifies severity and direction of impact
and makes decision on deployment of airbags
and pre-tensioners.
¥ Provides firing signals to all airbags and pre-
tensioners.
¥ Performs on board testing of the airbag and
pretensioner firing circuits, warning indicator
circuits and module status (Side Impact
Sensor performs its own internal checks).
¥ Stores fault codes in non-volatile memory.
¥ Drives the airbag warning lamp on the
instrument pack: if the warning lamp is
faulty (fault code recorded) an audible
warning tone is sounded.
¥ In the event of an impact, sends a signal to
the vehicle emergency message system
(VEMS) and the PCM to indicate that a crash
has occurred.
¥ Is connected to the data link connector via
the SCP data bus to enable communication
with an external PDU or scan tool.
¥ Provides temporary back-up power to operate
the airbags in the event of loss of battery
supply in an impact.
¥ In the event of an impact, records certain
data for subsequent access via the data link
connector. This data includes deceleration
information, firing delay and fault codes.
The RCM is bolted to the top of the driveshaft
tunnel below the center stack. Due to the
importance of the module being securely fixed to
the vehicle body, the ground connection is made
via the fixing bolts and is monitored by the
diagnostic system. A bad connection causes a fault
code to be generated.

the figures given in the JTIS Service instructions
must be adhered to. RESTRAINTS CONTROL MODULE

Note:An impact at an oblique angle may cause
both frontal and side airbags to deploy, depending
on how much lateral acceleration is sensed.

SIDE IMPACT SENSORSide Impact Sensor
The side impact sensors are mounted on brackets
attached to each inner sill.
The side impact sensor contains an electronic
discriminator sensor which detects side impacts
above a set threshold and signals a deployment
request to the RCM. Bag deployment only occurs
if the side safing sensor in the RCM has also
detected an impact.
The side impact sensor monitors its own internal
state, including correct ground connection, and
sends a regular ÔheartbeatÕ signal to the RCM
indicating that it is functioning correctly and is
available.
A 2 wire cable is connected between the RCM
and the side impact sensor. The cable has a dual
function, supplying power to the side impact
sensor and transmitting digital data to the RCM.
Diagnostics
The restraints control module (RCM) performs all
SRS diagnostics except those relating to the side
impact sensor internal faults and grounding faults.
When the ignition is switched on, the RCM carries
out a system Ôprove outÕ over an 8 second period
during which the airbag warning lamp on the
instrument pack is lit for the first 6 seconds.
During the prove out period all circuits connected
to the RCM are tested and also the state of the
RCM and side impact sensors (including ground
resistance and supply voltage).
If no faults are detected, the airbag warning lamp
remains off after the 8 second period.
If a fault is detected the warning lamp flashes a
two digit code five times and then remains lit until
the ignition is switched off. This is repeated on
each ignition cycle until the fault is cleared. Fault
codes are allocated a priority and if more than
one fault is stored in the RCM memory, the
highest priority fault is flashed. When this fault is
rectified, the next priority fault is indicated.
If the warning lamp itself is inoperative, the RCM
stores a fault code but no other action occurs. If a
system fault occurs when the lamp is inoperative,
a five ÔbleepÕ audible warning is sounded five
times with 5 second intervals. The audible
warning is repeated every 30 minutes and on
subsequent ignition cycles until the fault is
cleared.
If no faults are found during the system prove out
period the RCM continues to test the SRS system
during the remainder of the ignition cycle.Fault diagnosis of the side impact sensor is
normally carried out using the portable diagnostic
unit (PDU). Where the PDU is not available, the
flashing code on the airbag warning lamp indicates
the likely circuit or component fault.
