Seats
All seats are completely new to Jaguar with no
commonality to previous models.
Front Seats
The drivers seat and front passenger seat are
electrically adjustable for front and rear seat
height, fore and aft movement and squab tilt with
optional lumbar adjustment. Optional heated
cushions and squabs may be fitted with the heater
switches located on the centre console. The head
restraints are manually adjustable for height (four
positions) and tilt. The drivers seat also has an
optional two position memory facility. Side airbags
are fitted to both front seat squabs (see Occupant
Protection section).
Seat Construction
The seat track assembly consists of two slider
rails, cross mounted drive mechanisms and anelectrical harness sub-assembly. The seat cushion
pan is supported on four brackets attached to the
height adjustment drive actuators. Two separate
drive motors and screw actuator mechanisms
provide raise/lower movements respectively for
the front and rear of the cushion. The seat fore
and aft motor and drive shaft are located across
the front of the track assembly: note the drive
shaft must not be used to lift the seat assembly
when fitting or removing a seat. Each drive has a
potentiometer to register the selected position for
memory storage.
The track assembly wiring harness and driver seat
control module (DSCM) (driverÕs side only) are
fixed to a plastic tray which clips onto the frame.
The squab frame is a welded steel construction
which bolts to the track assembly and carries the
recline drive, lumbar support mechanism and a

28bracket for the airbag. The recline motor is located
in the lower left side of the frame and drives both
sides of the squab. The position potentiometer is
mounted on the long drive shaft on the RH side.
Lumbar support comprises a flexible steel lumbar
plate, motor, drive cable and return spring. The
top of the plate has vertical slots, fitted to a cross
bar, which allows the plate to be pulled down and
deformed by the drive cable to provide increased
lumbar support. If powered lumbar support is not
fitted, the lumbar plate is used without the drive
system.
When seat heaters are fitted each front seat has a
driver or passenger seat heater control module
fitted (DSHCM/PSHCM).
Seat Covers
The cushion and squab cover are made of dual
density foam and have optional heater pad inserts.
The cushion and cushion pan have an anti-
submarining profile for increased safety.
J.501.1786
Front Seat Adjustment
The front seats are adjusted by three switches on
the seat cushion side panel. The key does not have
to be in the ignition switch for seat adjustment.
Referring to the diagram:
A.Switch forward/rearward: moves seat cushion
forward or rearward
Switch up/down: raises/lowers front/rear of
cushion
B.Switch forward/rearward: raises/reclines angle
of seat squab
C.Switch front/rear: increases/reduces lumbar
support.

The centre console carries the ashtray and cigar
lighter, the cupholder and the armrest/stowage
compartment.
Lift the front of the hinged armrest to gain access
to the stowage compartment. A telephone can
also be fitted into the centre stowage
compartment as an option.

Glove Compartment
A glove compartment is located below the
passengerÕs airbag. Stowage is provided for the
DriverÕs Literature Pack. A CD autochanger can be
fitted within the glovebox as an option. The
glovebox lid, when opened, has a pen holder and
a location for a cup. A hook for holding small
items forms part of the handle.JOL.105

Seatbelts

REAR SEAT BELT RETRACTOR ASSEMBLIES
D.501.1465
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:
¥ 140 litre bag

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

SIDE AIRBAGS the pressure vessel to inflate the airbag. The
airbag is a top mounted assembly and deploys in
an upwards direction, climbing the windshield
before folding downwards. After deployment, the
bag deflates through two vents.
The airbag deployment door is an integral part of
the top fascia moulding. The airbag module is
bolted to the underside of the fascia via a steel
deployment chute and is also bolted to two
brackets on the tubular cross car beam which
supports the fascia assembly.
Note:The module is not handed. To access the
airbag module, the complete fascia assembly must
be removed.
Side Airbag
Side airbags are incorporated into the driver and
front passenger seat squabs and are similar to
those fitted to the XJ Series, using compressed
argon to provide the inflation gas. The bag has a
capacity of 19 litres and provides protection to
both the head and chest regions.
The side airbag module is fixed to the outer seat
frame and is located within a fabric deployment
pocket. The pocket is stitched to the seat cover
seam and when the module is triggered, this
length of seam bursts to provide the deployment
exit for the airbag.
D.501.1474
If a damaged seat cover is to be replaced, the side
airbag module must be removed and re-located in
the deployment pocket of the new seat cover.
The complete seat must be replaced if the airbag
has been deployed.

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
