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.

Hood
Unlike current Jaguar cars, the hood is hinged at
the rear with single pivot hinges and gas struts. It
has two primary and one secondary latch for
security. The primary latches are joined with an
intermediate cable and release of the primary
latches is by a single cable from the hood release
lever on the driver side of the vehicle. The two
primary latches are handed for LHD and RHD
vehicles. The secondary latch, mounted on the LH
side of the hood between the grille and inner
headlight, is provided for added safety and must
be hand released before the hood can be fully
opened. Hood sealing comprises front and rear
lengths of sponge bulb, pegged to the hood inner.

Fuel Filler Flap
The fuel filler flap/cap is located on the rear upper
part of the right fender. Fuel filler flap operation is
via an illuminated switch on the fascia or
emergency manual release by tag and wire in the
RH side of the luggage compartment. The cap,
when removed from the filler neck, is held by a
retaining strap which can be passed over the hook
on the flap to allow easy access for filling the tank
and to prevent scratching of the surrounding
paintwork.

JACK AND JACKING POINT
Jacking and Towing
The body has four jacking points located in
notches in the sill structure.
Caution:Extreme care must be taken when
positioning jacks or other lifting equipment that
the sills and sill panels are not damaged as the
vehicle is lifted.
For emergency short distance towing, or for
mounting the vehicle on a recovery trailer, LH
thread screw-in eye positions are located at both
the front and rear of the vehicle. The towing eye is
stowed with the vehicle jack in the luggage
compartment floor pan. To secure the vehicle
during road and ship transportation, tie-down
brackets are located under the floor pan. As with
current vehicles, the front vane must be removed
before attaching the towing cable.

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:

¥ 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

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.
Note:The torque settings are safety critical and
the figures given in the JTIS Service instructions
must be adhered to. RESTRAINTS CONTROL MODULE

Side Impact Sensor in order to deploy the
corresponding airbag.
Note:An impact at an oblique angle may cause
both frontal and side airbags to deploy, depending
on how much lateral acceleration is sensed.

compartment and a transfer module in the LH
compartment with external cross-over pipes for
fuel transfer between the compartments. Both
module assemblies have integral top plates for
external pipework and electrical connectors.
These are secured in the tank using screw on
plastic closure rings. The closure rings are
accessible from inside the vehicle via two access
holes in the floor panel below the rear seat. Due
to the confined working space and the possibilityof fuel spillage within the vehicle, it is advisable to
remove the tank completely before attempting to
remove the internal assemblies.

LOWER STEERING COLUMN
Lower Steering Column Assembly
The adjustable column assembly is connected to
the steering rack via a lower assembly consisting
of two shafts linked by a universal joint. The lower
shaft incorporates a sliding section which is
secured by a pinch bolt on installation. To stabilise
the shaft to shaft joint, the upper of the two shafts
is supported by a bearing assembly where it passes
through the bulkhead.
